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

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.

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

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.
