Understanding the Diesel Particulate Filter

In the early 2000s a newly developed part was beginning to see regular use on the emissions system of diesel vehicles. Today, that part, the diesel particulate filter, is used on nearly all diesel vehicles as a means of trapping harmful diesel soot from being released out of the exhaust pipe. Modern diesel vehicles run more more cleanly than those of decades prior mainly due to heightened government mandated emissions restrictions. The diesel particulate filter is what helped many manufacturers meet those new standards.

What is the diesel particulate filter and how does it work?

The diesel particulate filter is fitted into the exhaust system of a diesel vehicle to remove the diesel particulate matter, or soot, from the exhaust gas. The main purpose of the filter is to trap any particulates produced by incomplete combustion. As exhaust gas passes through the porous filter, made of ceramic, the particulates become trapped, helping to reduce harmful emissions.

Importance of keeping it cleaned

Many diesel vehicles utilize computer aided regeneration methods to help keep the filter clean. However, automatic regeneration methods require extended drive times at highway speeds, which isn't something that happens for all drivers on a regular basis. The truth is, most people spend more time in their car traveling short distances through the city, or sitting in stop and go traffic on the freeway. This prevents proper regeneration from taking place. So as the miles add up, it is likely that manual assistance to clean the filter will be necessary, as a clogged filter can result in a number of problems.

A clogged filter can result in diesel soot backing up into the engine, which can cause issues with many parts. The turbo, fuel injectors, and EGR solenoid can all become damaged if the filter is clogged, thus resulting in major performance problems and a need for even more spendy repairs. Another thing that can happen to clogged filters is cracking. This is worrisome because DPFs can be quite expensive to replace.

How it is cleaned

Aside from the regeneration process that takes place onboard, it is crucial that you allow a professional technician the opportunity to conduct forced regeneration. G2 Automotive rejuvenates the filter by spraying a high pressured chemical cleaner that is manufactured by one of the top oil companies in the country through the system. The process takes approximately 1 - 1/2 hours to completely regenerate the filter. This is the best way to ensure that your diesel's emissions system is performing as it should.

A few of the signs of a clogged DPF include increased idle speed, a slight increase in fuel consumption, constant running of the cooling fans or a change in engine note. Your vehicle may also equipped with a DPF dashboard warning light, informing you it is in need of service. If you need diesel particulate filter regeneration in Cumming, GA head to G2 Automotive.
