Why DPF and DOC Recycling is Important

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

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

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

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.

Turbochargers

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

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

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

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 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

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.

Maintenance

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.
