What You Need to Know About Diesel Air Filter Cleaning

The air filter is a key component for any fossil fuel driven engine, and this is particularly true in regard to diesel engines. Air filters help to remove dirt and contaminants before the air reaches the engine, thus preventing catastrophic issues. However, over time, air filters become clogged with debris and this reduces their effectiveness. Here is some information on what you need to know about diesel air filter cleaning.

Inspection Process

During the Inspection Process, the Air Filter will be Checked for Tears and Pinholes.

The first phase of air filter cleaning is the inspection process. During this process, the filter media will be evaluated to ensure that the filter itself is suitable for cleaning. In most cases, a high-powered light is used to check for imperfections, such as tears and pinholes. Using a light also helps to keep the filter from being damaged during the inspection.

Air Filter Testing

The Testing Phase is Used to Determine the Viability of the Filter.

Once the filter has been inspected, it will move on to the testing phase. The testing phase requires the use of a manometer, which will measure pressure fluctuations as air is passed through the filter. These measurements can then be compared to standard operating criteria in order to determine the quality of the filtration media. Testing will also indicate whether the filter is fit for service.

Cleaning Solutions

The final stage of air filter cleaning involves the use of a dry-cleaning machine. Dry-cleaning machines utilize several vacuum nozzles to pull debris from the filter, while the filter remains sealed in a cleaning chamber. This helps to ensure that the entire filter has been properly cleaned and is ready for use, and this includes both the inside and the outside of the filter.

Always Consider Air Filter Cleaning

Changing air filters can be an expensive undertaking and one that can be avoided by having the filter cleaned. In turn, your truck will increase its fuel mileage rate and run more smoothly. And although there are a few steps in the cleaning process, each is vital in ensuring that the air filter will function properly. The filter will first need to be inspected for tears and other imperfections. From there, it will be tested for unwanted drops in pressure. After the filter has been inspected and tested, it will be cleaned in a vacuum chamber, thus removing dirt and grime from both sides of the filter. If the air filter in your diesel truck is not functioning at full capacity, then you will surely want to consider having it professionally cleaned.

Benefits of Using Aftermarket DOC and DPF Replacement Parts

There is no doubt that on-road trucks take their fair share of abuse by racking up miles very quickly and as these miles accrue, it brings about the necessity for replacement parts. This is especially true when it comes to diesel oxidation catalysts (DOCs) and diesel particulate filters (DPFs). DOCs and DPFs are used together as a means of ensuring that diesel engine emissions are free of pollutants. And while these components can be purchased brand-new when the units need replacing, aftermarket parts are well worth the consideration. Here are the benefits of using aftermarket DOC and DPF replacement parts.

Newly Manufactured

Aftermarket Replacement Parts are Actually Newly Manufactured.

It may come as a surprise, but aftermarket replacement DOCs and DPFs, such as those by Roadwarrior, are actually newly manufactured products. This means that the primary components have been replaced with new parts and not those that have been re-manufactured or re-conditioned. In fact, these parts are typically made from high-quality materials, such as 409 stainless steel, and this helps to ensure that the unit functions as if it were new out of the box.

The Perfect Fit

If you are familiar with semi-trucks, then you are probably aware that there are many different manufacturers and many of these require unique DOCs and DPFs. Thankfully, these aftermarket parts are manufactured to fit nearly any model of truck, including popular brands like Caterpillar, Detroit Diesel, Cummins, Kenworth, and much more. To ensure that the part will fit your truck properly the unit can be cross-referenced with OEM part numbers.

Backed by a Warranty

With a Warranty, there is No Needed to Worry About the Part Malfunctioning.

Not only are aftermarket DOCs and DPFs designed to fit the vehicle perfectly, but they are often backed by a warranty. When you purchase a part that has a warranty there is no need to worry that the unit will malfunction, as it will be replaced with no cost to the operator. Of course, with such rigid manufacturing standards, issues with aftermarket DOCs and DPFs are kept to a minimum.

Always Consider Aftermarket Replacement Parts

Diesel oxidation catalysts and diesel particulate filters are a necessity in reducing the emission of harmful chemicals into the atmosphere, and, as with most parts, they require replacing before becoming faulty. When it comes time for maintenance, you will want to consider aftermarket parts. Both aftermarket DOCs and DPFs are newly manufactured and never remanufactured, and this means that they will function as if they were new. In addition, aftermarket replacement parts come in an array of sizes that will fit nearly any model of truck. Furthermore, most replacement components come backed by a warranty, so there is no need to worry about the parts operating properly. When the diesel oxidation catalyst or the diesel particulate filter on your truck becomes faulty, always consider these benefits of aftermarket DOC and DPF replacement parts.

Why DPF and DOC Recycling is Important

It is no secret that Diesel Particulate Filters (DPF) and Diesel Oxidation Catalysts (DOC) are vital in reducing the amount of harmful chemicals that are emitted into the atmosphere by diesel engines. But did you know that both DPFs and DOCs can be recycled, rather than being pitched in the trash? Here are some reasons why DPF and DOC recycling is important.

Monetary Value

One of the most overlooked aspects of DPF and DOC recycling is the monetary value of the components. This value comes from the platinum metals that are used as a means of ensuring that the chemicals in the exhaust stream are being mixed correctly. When properly recycled, these platinum-group metals can be extracted from DPFs and DOCs that are no longer functioning adequately. In fact, a spent DPF or DOC system can be worth over $500, and this is substantially more than the amount of money that would be received if the parts were to be scrapped. Not to mention, recycling is a far better option than having the part hauled away to the garbage dump.

Helps Lower New Part Prices

Recycling Parts Helps to Keep Supply and Demand in Balance.

Recycled DPF and DOC systems also help to keep new part prices down by because they make for a more sustainable supply chain. Since the spent parts can be reused, it costs manufacturers less money, as they will not have to continually invest in all new components. Not only this, but recycling also goes a long way in keeping the supply and demand curves at equilibrium, because there is less likelihood of a drop in supply. Therefore, so long as demand does not skyrocket, then prices will remain stable. In addition, this ability to reuse the certain parts means that there will be a decrease in waste materials and, in the end, these savings can really add up. These savings can then be passed on to customers through various discounts and refunds, and this bodes well for both businesses and consumers.

Always Consider Recycling DPFs and DOCs

Diesel particulate filters and diesel oxidation catalysts are very effective in keeping the environment a much cleaner place, and when they are recycled, rather than thrown in the garbage, it only increases the positive nature of the components. By recycling DPFs and DOCs, businesses can save money by extracting the valuable metals used in the system and that value can be passed on to customers in the form of savings or refunds. In addition, recycling parts help keep the supply in check, so that the overall prices do not rise unexpectedly. Keep these reasons in mind when recycling your DPF or DOC components.

External Factors that Can Affect DPF Performance

There is no doubt that a diesel particulate filter or DPF is very important in keeping harmful chemicals from being emitted into the atmosphere. After all, keeping the environment clean is something that everyone should be concerned with. And while having a clean DPF will help the environment, it can also go a long way in ensuring that your truck is running properly. Here are some external factors that can affect the performance of the DPF.

Air Filter Cleanliness

Ensuring that the Vehicles Air Filter is Clean is a Must for a Proper Functioning DPF.

Having a clean air filter is just as important as having a clean DPF, as an unclean air filter can actually lead to build-up within the DPF. If your truck’s air filter is dirty, then chances are it is not allowing for adequate airflow to the engine and this can cause changes to the air/fuel ratio. When the air to fuel ratio is not correct this means that the cylinders will not be able to process the fuel properly. In the end, this could lead to an increase in the potential of the DPF becoming clogged.


It is always recommended that you continually monitor your vehicles turbocharger to ensure that it is functioning properly. If a turbocharger has a leaky seal or it is not allowing for adequate amounts of air to enter, then this can lead to a buildup of oil and soot in the exhaust system of the truck. Down the line, this soot buildup could cause the DPF to become plugged, and thus, malfunction.

Engine Oil

Make Sure that You Use Certified Oil to Reduce Ash Emissions.

One of the most overlooked aspects in helping to keep the DPF clean is the type of oil that is being used in the vehicle. When you are considering oil for your truck, make sure that you go with one that is CJ-4 rated, as this type has minimal ash generating properties, and this can help increase the longevity of the DPF system and reduce harmful chemical emissions. Furthermore, if you notice that the vehicle is using excessive amounts of oil, you will want to have it inspected immediately to prevent further damage to the DPF.

In Summary

There are many facets of vehicle maintenance that can have an effect on the DPF, and therefore it is important to have your vehicle regularly inspected. For instance, a dirty air filter may be all that it takes to increase the amount of fuel being burned in the cylinders and this could eventually lead to DPF clogging. In addition, if there is a turbocharger installed on your vehicle, you will want to make sure that it is properly sealed so that it does not promote the buildup of soot. Lastly, it is vital that you use an approved oil that has low ash generating properties. By keeping these things in mind, you will help to ensure that the DPF functions correctly.

Reasons You Need to Use New Clamps After DPF Cleaning

One of the most important steps that over-the-road truck drivers need to take before hitting the highway is to ensure that their DPF system is properly cleaned. And although bake cleaning is necessary to clean the ash from this inside of the unit, there are external components that need to be replaced with every cleaning, such as the clamps and gaskets. Here are the reasons that you need to use new clamps with each DPF cleaning.

Clamps Are Often Over Tightened

If you are not used to replacing the clamps on a DPF device, then there is a chance that you will inadvertently over tighten the clamps. When the clamps are tightened too much it can make them difficult to remove, especially when they have been put through 150,000 miles of varying weather elements. In addition, when clamps are over tightened it can ruin the threading, which could cause a failure of the clamp altogether.

Clamps May Strip During Removal

Threads Can Become Stripped When They Corrode.

A common problem during the removal of the V-clamps that are used to hold the DPF unit in place is thread stripping. The primary reason that clamps strip during the removal process is because they have been over tightened and this causes the threading to become compromised. In addition, there is a certain level of corrosion that occurs with V-clamps when the have been subjected to wet conditions for extended periods of time and this can increase the chances of the clamp stripping during removal.

The V-Clamps are Meant for One-Time Use

V-Clamps on a DPF System are Only Meant to be Used One Time.

The foremost reason that you need to use new clamps after DPF cleaning is the simple fact that they are only meant to be used one time. This means they are not meant to be removed and then re-tightened after the cleaning process has been completed. As mentioned, there are various factors that will deteriorate the V-clamps, such as weather conditions and moisture, and in the end, this could cause the clamp to fail. While you are having the DPF bake cleaned and the gaskets replaced, you will want to ensure that new clamps are used as well.

To Conclude

There is no doubt that having the DPF cleaned is a great way to increase fuel mileage and ensure that the there is no ash built up within the unit. However, when you are considering a DPF cleaning, it is important to replace the V-clamps that hold the system in place, and also the gaskets. Always consider these reasons that you should replace the V-clamps with each DPF cleaning.


Fuel Economy and Your Truck Fleet

Fuel consumption is the second largest expense for any truck fleet and affects revenue more than anything besides labor. The long haul trucking industry has a thin profit margin, to begin with, and with the average truck drives thousands of kilometers each year fuel costs per unit to eat into the bottom line. When it comes to saving money; there are many things that you can do to stretch your company dollar.

Slow Down

Slowing Speed can Reduce Fuel Consumption by 27%.

Deadlines and delivery dates affect your bottom dollar but slowing down can have the same impact. Reducing your speed by just 15km per hour from 120km to 105 can reduce fuel consumption by 27%. With fuel prices rising and oil prices dropping, this is one of the quickest and easiest ways to lower your fleet’s fuel consumption and lessening the wear and tear on your engine as well.


Idling is a huge gas guzzler and during the Canadian winters, trying to eliminate idling is almost impossible. With many products and technologies on the market such as automatic engine shut down systems and truck stop electrification that will help reduce unnecessary idling, you can cut down on fuel consumption. The average long hauler can idle between 6-8 hours per day costing the fleet operator around $6000 per year per vehicle.


Proper Maintenance can Save Thousands.

Maintaining a properly running engine and its components can save thousands of dollars per year. From tire pressure to regular cleaning of DOC and DPF Filters, every bit of maintenance will cut down on wear and tear as well as fuel consumption. DOC filters should be cleaned every six months to 1 year.The process only has a 24-hour turnaround for regular cleaning and can save up to 5% in your overall fuel economy. Using low viscosity lubricants reduces friction and energy losses and on axle and transmission parts can save up to 2% fuel consumption during our cold winter months.

Drivers Training

When your drivers undergo drivers training and monitoring, the cost savings on fuel consumption are noteworthy. Studies have shown that drivers training can save over 1200 dollars per year which is about a 20% fuel consumption savings. Using cruise control, braking and accelerating smoothly, and block shifting are all skills that help in the amount of fuel your fleet consumes yearly.

Every fleet operator wants to maximize profit while minimizing costs. When you take into account the amount of money you could save by looking at your fleets habits and fuel consumption, the numbers are staggering. Start with regular maintenance of your long haulers, taking filter cleaning into account, then go down the checklist to see what other choices you can make to add extra profit to the bank and longevity within your fleet.

Greener Businesses Attract Public Support; Why Retrofitting Your Fleet Pays Dividends In The Long Run

Pollution on the Rise

As the amount of roadway traffic grows yearly, the need for greener alternatives and implementation also intensifies. The strict government standards regarding emissions evolves on a regular basis, and many companies are beginning to follow suit. Finding ways to gain public support and grow your business while doing your part in the environmental issues at hand has become a two-fold endeavor. What measures can you take that will meet government regulated standards, and build your public profile?

There are many retrofit items you can install post factory that will meet and exceed government regulations. The Diesel Oxidation Catalyst (DOC) is a proven choice for many heavy duty diesel owners. This aftermarket retrofit is a pollution controlling device that uses a chemical process to break down harmful emissions. The stainless steel casing houses a ceramic honeycomb substrate that is coated with a material which causes a chemical reaction with harmful pollutants like carbon monoxide, gaseous hydrocarbons, and sulfates. The contaminants are absorbed within the carbon particles, and less toxic components are emitted.

Making the Change to Sustainability

Taking the appropriate steps in outfitting your fleet with emission controlling add-ons, is a fantastic way to take that first step in becoming a sustainable, environmentally friendly enterprise. We all understand and recognize the damaging effects of pollution on our health, our children’s health, and the environment. There are more studies than we can count that prove this unfortunate branch of the transportation sector. 1/3 of NOx emissions and ¼ of particle matter emissions come from heavy-duty trucks and buses.

How does making the decision to retrofit your fleet with Diesel Oxidation Catalysts equate to more public support and perhaps a more profitable bottom line? Green initiatives can lead to a reduction in overall costs as well as higher sales. Many businesses are demanding their affiliates follow sustainable practices and as a result, those affiliates are reaping the rewards. When your fleet becomes greener, your pocketbook grows as well.

Gaining Support, Clients, and Contracts

Showing you are a sustainable business is great for marketing. There are large corporations like Wal-mart that will only deal with companies that are trying to demonstrate sustainability. Going Green is no longer a hippie movement. It has become a global movement, and individuals and business alike are taking a stand. Diesel Oxidation Catalysts are an integral step in taking that position and exceeding federal guidelines for fuel emissions. When you can showcase your efforts to potential clients, you can reap the rewards of gaining business,  attracting customer support and maximizing your profit.

DOC’s only take a small amount of time to install, and the initial investment will pay itself off quickly. Take the steps today to start gaining traction in the public eye as well as in business growth. Being environmentally sustainable does not have to affect your bottom line!

Bill M232 — Motor Vehicle Amendment Act, 2017

For many decades, researchers, scientists, intellectuals and environmentalists have been debating the bad state of air pollution that the planet has got into. Presumably, this air pollution will continue to worsen with the increase in vehicular air pollution.

Tiny, sooty particles released by the diesel engines have led to premature deaths and many health issues. Keeping this in mind, in 2009, diesel particulate filters (DPF’s) became a mandatory component for all diesel automobiles.

All was going well in the province – people were driving DPF installed vehicles, and the air pollution was being kept in check until people started committing the sin of removing DPFs from their vehicles. There were some compelling reasons why people made such an attempt:

  1. Removal of DPF was appealing to the owner since the harm caused by a blocked DPF led to expensive repairs.
  2. Removal of DPF reduced the need for maintenance and replacement of the filter.
  3. Removal of DPF meant lower consumption of fuel.

Though beneficial for the vehicle, such a move was extremely harmful for the environment.

According to Paul Clark, Managing Director at European Exhaust and Catalyst, DPF removal is a risky deal to seal. He stated, ‘Not only will it invalidate car insurance and potentially fall under the veil of tax evasion due to low emissions based road fund licensing, but it can damage the performance of the vehicle as well’.

To keep your expenses under control, you should get the DPF in your vehicle regularly cleaned to save yourself from the cost of buying a new one.

Considering the downsides of removal of DPF, the B.C. government has revised the Motor Vehicle Act that makes tampering with the emission systems in the vehicles a punishable offence.

A Brief about the Latest Bill That Amended the Motor Vehicle Act

Since the inception of The Motor Vehicle Act, the Act has been revised for a number of times to make the air safer to breathe.

This time, the bill introduced in the legislature focused on amending the Motor Vehicle Act by eliminating the interference with emissions control devices in motorized vehicles. With this alteration to the Act, the BC legislation would be able to stand in the same stead as that of Ontario’s Environmental Protection Act and the Clean Air Act in the United States.

The Key Points of the Act are:

  1. One should not drive an automobile in which there is no device incorporated to minimize the discharge of contaminants by the diesel vehicle.
  2. Nobody is permitted to remove the emission system installed in the vehicle to avert the release of any pollutant into the atmosphere unless permitted by subsection (6).
  3. In the case of impairment of the device installed, the owner is required to get it repaired or replaced.
  4. Breaching of this section by any individual is an offence that makes him/her accountable to pay a penalty of not less than $50 and not more than $5,000.

Ensure you abide by the rules and regulations of the Bill M232 — Motor Vehicle Amendment Act, 2017 to make sure the air we all breathe in is pollution free.

How Important Is It To Keep The Diesel Particles Out of the Atmosphere?

Diesel exhaust is a compound mix of gasses and fine particles. Diesel fuel emits several dangerous emissions when it is burned.

Diesel fuelled automobiles are the chief sources of harmful pollutants in the atmosphere. Various health studies have assertively claimed that diesel engines can have serious health dangers. Exposure to diesel exhaust largely disturbs the respiratory system and leads to asthma, allergies & bronchitis and deteriorates functions of lungs. Though everyone is vulnerable to diesel pollution, people with pre-existing respiratory issues are more susceptible to these harmful particles. High exposure to diesel exhausts has increased heart problems, premature deaths, and lung cancer.

Keeping in mind the threat of diesel exhaust, modern cars have to be fitted with a Diesel Particulate Filter (DPF) to stop this soot from passing into the air. Moreover, the government has made diesel particulate filter check mandatory for diesel cars and trucks.

Why is DPF necessary and beneficial for the atmosphere?  

Diesel vehicles have gained a lot of popularity throughout the world because of the advancement in diesel engine technology. Diesel cars give excellent fuel economy over petrol vehicles.

Since diesel cars emit a high amount of NOx and particulate emissions when juxtaposed to petrol cars, many green initiatives were introduced by vehicles manufacturers to minimize pollution. Out of the many green initiatives, the introduction of diesel particulate filters was considered to be one of the most significant initiatives.

When diesel is burned in a combustion engine, it produces large amounts of soot that is released in the exhaust. Soot particles are a by-product of the diesel exhaust that forms the primary cause of pollution in the atmosphere. It is compulsory to eradicate the soot particles for a smooth performance of the car and green environment.

The catalytic converters fixed in all vehicles are not adequate to make the harmful gases safe and eco-friendly. For this reason, DPFs have become a legal requirement. These devices eliminate soot from the exhaust of a diesel engine and help in averting the release of the dangerous particles into the atmosphere. The particles get trapped in the filter and are further emptied on a regular basis to sustain the performance of the automobile.

DPF Cleaning

The process of cleaning the DPF is known as regeneration. The regeneration method has three types – active, passive and forced. The collected soot is burnt off at a high temperature and leaves behind only a residue of ash. With efficient regeneration process, the DPF is ready to take on more pollution from the diesel engine.

In case, the regeneration process is not conducted properly, the soot will get accumulated, impacting the performance of the vehicle and leading to costly repairs. Many diesel car owners prefer deleting or removing the DPFs to escape expensive repair & replacement and increase the engine performance. However, one must never forget that removing, bypassing or modifying DPFs has both legal and social repercussions.

What are the Causes of DPF Failure Really?

Due to the high petrol prices and adequate performance, diesel vehicles have always been a more friendly option for people’s pockets. But what about the dreaded DPF filter?

Your vehicle’s particulate filter removes diesel soot from the exhaust gas of a diesel engine, and like any other filter, it slowly gets clogged up with the soot that it traps.

When you buy a diesel car, you think: ‘come on, the DPF located within my car’s exhaust system regenerates automatically, which is why this filter will never trouble my ride.’ Well, do you know that a DPF needs high temperatures to self-clean automatically? Low mileage and short journeys will leave you distressed with a blocked DPF. Let’s list down our top 4 causes of DPF failure:

Regular Short Start-Stop Journeys

Repeated short drive times at less than highway speeds is a practical reality in today’s world, where the roads witness high traffic, red lights and brake lights.

A good DPF regeneration takes place at a higher engine speed and with the kind of driving that most people are bound to practice, the vehicles probably never gets hot enough to regenerate.

The worst part is: when you drive with a dirty filter, your engine works harder than it should be; so, unfortunately, you have to experience less power, poor fuel economy, and more damage.

Wrong Engine Oil

Many people use standard engine oil for their vehicles. However, this is a wrong doing. Vehicles fitted with DPF’s are special vehicles that require a Low or Mid SAPS engine oil. SAPS means “Sulphated Ash, Phosphorous, and Sulphur.” A low SAPS engine oil has a smaller quantity of Sulphated Ash, Phosphorous, and Sulphur, preventing the DPF filter from becoming prematurely blocked.

Issues with EGR

An anti-pollution device, the Exhaust Gas Recirculation (EGR) valve is designed mainly for minimizing the amount of nitrogen oxide (NOx) emitting out of the vehicle’s exhaust pipe.

The carbon dust inside the exhaust gasses clogs up the EGR system, reducing the movement of EGR valve. Due to this, the engine doesn’t function properly, leading to inefficient fuel consumption and more carbon dust production.

Soon, this causes a DPF to become jammed.

Turbo Failure

Mind you; good quality turbochargers rarely become faulty. Let’s get this clear: without the correct operating conditions, these components will perform ineffectively.

So, if there’s a turbo failure, your diesel engine will produce more of the revolting black soot than the usual. In such a scenario, a faulty turbocharger will also be responsible for the leakage of a huge amount of oil into the fuel system, further leading to the DPF being drowned in an ocean of engine oil.

Implementation of new 2016 Vehicle Inspection Manual

British Columbia Takes Highway Safety Seriously

The Vehicle Inspection & Standards program is keen on improving vehicle and road safety in the westernmost province of Canada, British Columbia. This program covers all types of highway vehicles – both private and commercial.

Commercial Vehicle Safety and Enforcement (CVSE) endeavors to have only the most roadworthy and safest highway automobiles operating on BC’s highways, through the proper application of the British Columbia Motor Vehicle Act, Motor Vehicle Act Regulations, Vehicle Inspection Manual and Canadian vehicle manufacturing standards.

In this pursuit, CVSE has released an updated version of its Vehicle Inspection Manual. The new 2016 Vehicle Inspection Manual replaces the Vehicle Inspection Manual 2010 and comes with revised inspection criteria, which define the minimum mechanical standards that automobiles must fulfill to operate on-highway in British Columbia.

2016 Vehicle Inspection Manual will affect the whole MVA Truck, Trailer and Bus Inspection requirement

A new version of Vehicle Inspection Manual was enacted on July 1, 2016. Authorized inspectors who will conduct all inspections at a Designated Inspection Facilities (DIF) or Preventative Maintenance Facilities (PMP) throughout the province are required to inspect to the criteria noted in the current year’s Inspection Manual. It is necessary for these authorized inspectors to ensure that all vehicles satisfy minimum requirements and are in compliance before issuance a certificate of approval.

CVSE will provide a 90-day transition period to September 30, 2016, to ensure plenty opportunity for all facility operators and authorized inspectors to obtain and familiarize themselves with the new requirements and inspection criteria. Full enforcement will start following this transition period.

Get VIM and Other Documents in BC

The Vehicle Inspection Manual and the associated documents are available through the Queen’s Printer of BC at http://www.vsis.qp.gov.bc.ca. Additional information, bulletins, notices, and circulars are available from the CVSE website at http://www.cvse.ca– under “Vehicle Inspections & Standards.”

Had The Emission Altered On Your Vehicle’s DPF System? You’re In Trouble!

Whether you are living in British Columbia or moving to the province, it is necessary for your vehicle to pass a safety check. You must get safety inspections done by private mechanics, authorized by the B.C. Ministry of Transportation. These private mechanics will use the Vehicle Inspection Manual to guide them in measuring the safety of your vehicle during their inspection.

The inspection procedures and criteria for emission controls and devices have not altered in BC, but the profile of inspecting emission control equipment will be more important in the inspection process because this item is now recognized separately in the Vehicle Inspection Manual.

Over the past decade, some garages have dismantled emissions control devices to reprogram the engine for better performance, improve fuel efficiency and address reliability problems. This has become a serious concern for the British Columbia Trucking Association (BCTA), since altering or tampering emissions control devices undermines environmental benefits.

The new Vehicle Inspection Manual is a way to end such harmful practices and enforce clean diesel regulations. The 2016 VIP also ensures that BC Motor Vehicle regulatory standards, Canadian Manufacturing Standards, and National and International Vehicle Safety Standards are applied. Only safe, pollution-free and environmental-friendly vehicles will be operated on BC roads.

The new manual version will identify those vehicles that have had their emission systems modified. Therefore, those trucks that have had the emission altered on DPF system will fail the safety check; making it harder for these automobiles’ owners to get a Motor Vehicle Inspection sticker.

Purchase A New DPF To Certify Your Truck Under The VIP

This means that many drivers will be stuck with trucks they can no longer certify under the Vehicle Inspection Program. To obtain Motor Vehicle Inspection sticker, these truck owners need to reverse the process by purchasing a new particulate filter.

If you need to buy aftermarket DPFs in British Columbia, look no further than Re-Flow Solutions.

Diesel Filters – A Must for Every Vehicle

Since 2009, indispensable pollution filters called diesel particulate filters (DPFs) are a must for new diesel cars. Recently, more than a thousand diesel vehicles have been caught without a DPF, contributing largely to air pollution-related deaths.

Shocking Revelation of Removed Pollution Filters in Diesel Cars

In the United Kingdom, nearly 29,000 people die premature deaths each year due to tiny, sooty particles emitted by diesel engines. Soot can end up deep inside people’s lungs leading to an array of health problems. An investigation has revealed that pollution filters have been deliberately removed from the diesel cars when their DPFs become clogged and cause breakdowns.

Engines will breathe again, but humans may not!

According to a garage owner, the only solution for vehicles with DPF problems was DPF removal. Replacing DPFs can cost up to £2,500, so, it was a cheap shot to get it removed totally for a few hundred pounds. It’s shocking that many garages offer DPF removal and advise it for increasing power and fuel efficiency of vehicles, with one promise “your engine will breathe again”. These garage owners forget the harm they are causing to the health of living beings.

Driving a car without a diesel filter is an offence. This is because a car without a DPF is more polluting than ever and, therefore, it is unfit to drive. Recent tests have confirmed that diesel vehicles pollute far more in the real world than in laboratories. And so, removing pollution filters is the last thing on the planet that should be allowed.

Smart Move Will Not Be Smart Enough Anymore In the Future

Some corrupt garages remove filters in a manner which avoids detection. They offer to discreetly cut a small window in the top of the chamber, so as to remove the internal filter before re-welding the window and refitting to the diesel car. It is a dodgy move to show a vehicle has a DPF fitted. According to Clean Air in London (CAL), a lot of diesel vehicles are likely to have been interfered with in this way.

In 2014, the government ministers introduced a visual check into the MOT test, to end the unacceptable, dodgy DPF removal practice. According to new figures given to the Guardian by the Department for Transport (DfT), until now, 1,188 vehicles have been caught without DPFs.

The roads minister of UK, Andrew Jones, said that they are fully committed to improving air quality. Hundreds of polluting vehicles are getting off the road, and new ways are investigated to use the advanced technology to further improve detection methods.

So, people must ditch dirty diesel and switch to cleaner vehicles with DPFs.

Regular DPF Maintenance- An Ideal Solution for Maintaining Your DPF

Diesel Particulate Filter cleaning is possible and costs less than replacement. Not only does regular DPF maintenance ensure longer DPF life, but it also runs your equipment smoothly and efficiently.

Purchasing a Re-Manufactured DPF is a Big Mistake DPF: Earth’s Best Friend

Since diesel engines emit pollutants into the air, new diesel engines have been fitted with a diesel particulate filter (DPF) to reduce the amount of impurities in our air. DPFs have become crucial for new diesel cars since the year 2009.

Diesel Particulate Filter Failure

Like any other filter, the DPF will get clogged slowly with the soot that it traps. DPFs need high temperatures to regenerate (clean) themselves. However, due to low mileage stop-start motoring, regeneration may not complete, leading to DPF blockage. Should an orange light be ignored, the engine will lose power and eventually stop. Only if the car is driven at a constant speed, for at least fifteen minutes, the DPF will heat up enough to regenerate

Re-Manufactured DPF: The Worst Alternative to a New DPF

DPFs need replacement after a certain mileage (between 80,000 and 150,000 miles) has elapsed, depending on the usage and proper engine care. A new DPF for a diesel car costs more than £1000.This is why a lot of people these days are buying new aftermarket DPFs to save their money. But most people do not know how harmful this practice can be. Let us explore the risks of re-manufactured diesel particulate filters.

Although buying a re-manufactured DPF saves you up to 65% money compared with the main dealership price, it is nothing but a used DPF that has been cleaned and is being re-sold. Well, do you really want to pay a premium price for DPF cleaning?

Re-manufactured DPFs fail soon

Outwardly, almost all re-manufactured DPFs seem to be the same as any other DPF. The trouble is that one can never be aware of the condition of the DPF core.

Mostly, the core of a re-manufactured DPF has been used to a great degree. This is why a re-manufactured DPF has a short life span.

The truth is you have saved initially on a re-manufactured DPF only to erode your savings as soon as the part fails and demands to be replaced.



Cleaning A DPF: The Best Alternative to Re-Manufactured DPF

Cleaning a DPF will cost less than a re-manufactured DPF and offer the same end result. Avoid exchanging your DPF with a re-manufactured part. Simply get your DPF cleaned and avoid costly downtime of your vehicle.

When a DPF cannot be cleaned, it is worth the investment to buy a new one.

Why Diesel Oxidation Catalysts (DOC) Succeeds? Increasing number of Vehicles behind Pollution

Pollution, pollution, everywhere! With every passing day, as the number of vehicles increases on the roads, it seems that this social issue will never be taken care of!

Do you know that the heavy-duty trucks and buses account for about one-third of NOx emissions and one-quarter of PM emissions from mobile sources? Yes, it’s true!

Air Pollution and Human Health

Although in the present day, the government has imposed strict standards for the heavy-duty diesel vehicles, some existing trucks and buses still emit harmful gases that contribute to extremely serious health issues such as asthma & lung damage.

And, all this is because of the diesel exhaust released from the diesel vehicles that penetrates deeper into our lungs and affects our health. Children as compared to adults are more vulnerable to air pollution since their respiratory systems are still in the developing phase.

Solution to Pollution

But, as they say, where there’s a will, there’s a way, and so, there is hope for pollution too! With the advancement in technology, the device to reduce the pollutants (unwanted bi-product of older, diesel-fueled heavy duty vehicles) has become no less than a blessing to humankind.

Here, we are talking about diesel oxidation catalyst. This pollution controlling device is beneficial for upgrading a diesel engine to make the atmosphere less polluted.

What exactly is DOC?


Example of RoadWarrior DOC

A DOC is a pollutant reduction device that utilises a chemical procedure to break down pollutants in the exhaust stream into less injurious components. It consists of a stainless steel canister that contains a ceramic honeycomb-like structure called a substrate coated with a material that causes a chemical reaction to control pollution.

DOC- The solution for every diesel vehicle

In the case of diesel exhaust, the catalyst oxidises carbon monoxide, gaseous hydrocarbons, and unburned fuel and oil absorbed on the carbon particles. The unburned fuel and oil are called soluble organic fraction, and can make up a crucial part of the particulate matter.

A flow through oxidation catalytic converter installed on a vehicle can control the soluble organic fraction (containing harmful chemical pollutants) of the particulate by almost 90%. Not only this, but it also eliminates the detestable odour of diesel exhaust. It also reduces carbon monoxide and gaseous hydrocarbons emissions, from 60% to 90%.

Whether it is on-road sectors or non-road, DOC has become one of the most successful strategies to control pollution all around the world.

How DOC works with DPF to reduce emissions from a diesel engine?

Catalytic generation of NO2 more toxic than NO


Catalytic generation of NO2 can create air quality issues in some applications. Because of the thermodynamic equilibrium of reaction, reached in the atmosphere after a while, regardless of the original composition of NOx, the oxidation of NO tends to be of less concern in most surface applications. Nitrogen dioxide can be effectively used for the regeneration of diesel particulate filters (DPF).

In today’s diesel emission control systems, often DOCs are specifically designed for high NO2 production to support the operation of DPF systems.

Need DOC cleaning?

Do you know that after all the magical work that DOC performs, regarding pollution control, it even needs cleaning just like your DPF?

Yes, it’s a must!

Benefits of having proper maintenance of DPF New standards set for diesel vehicles

What role does the DPF play?

A Diesel Particulate Filter is located within the exhaust system to capture small soot particles and prevent them from being released into the atmosphere. The DPF’s role is to clean up particulate matter in an environmentally friendly way.

But being a filter, after all, it needs periodic emptying and most of it is done automatically through the process of regeneration. In this process, the captured soot particulates are burnt off.


Is regeneration enough for filtering the DPF?

Is hitting the regeneration button enough for the proper maintenance of DPF? Regeneration only burns up combustible particles, while the non-combustible materials are still left behind in this filtering process. So the answer is No! The right cleaning of Diesel Particulate Filter takes place when the DPF is removed from the automobile and put through a special cleaning process by an expert.


Why proper maintenance of DPF is essential?

The regen cycle is a great invention and vital to combust much of the accumulated particulate matter. However, when it comes to getting noncombustible materials filtered, there are people in British Columbia who tend to act lazily!

But do you know how much the remaining residue can damage your engine! Well, a lot! How?

Here’s how…In the DPF, the left out particles:

  • create back pressure that increases regeneration downtime
  • affect the vehicle by reducing its horsepower
  • impact the fuel economy negatively
  • damage the filter

And, finally, the engine starts getting damaged.


Whether it is your pick-up truck, Tier 4 Equipment or heavy-duty diesel engine  DPF cleaning is crucial. An unmaintained DPF runs your equipment unnecessarily hard and less efficient, so, it’s time you get it perfectly maintained!


Here are 6 benefits you can enjoy with regular DPF maintenance:

  • Increased Fuel Economy up to 5%
  • Increased Horsepower
  • Longer DPF Life
  • Optimized DPF Performance
  • Less Unwanted Downtime
  • Lower Overall Maintenance Costs


Maintenance of DPF is recommended every 6 months to 1 year (Intervals vary by usage). Save a lot of dollars & time by getting your DPF cleaned- the first time right. Get your DPFs absolutely clean in one go! Restore your DPF to nearly new!

If your Truck or Equipment DPF remains dirty after a DPF cleaning service, your fuel economy will reduce, costing you a lot of dollars with each mile driven. Get a really clean DPF and save ample amount of money spent on fuel & time spent on the regeneration process.


Also, get air filter cleaning done from time-to-time so as to avoid costly replacement of the filters.
