Understanding DPF Maintenance Services

Diesel particulate filters (DPFs) are emission control devices designed to clean the exhaust emitted by vehicles' diesel engines. Diesel Performance Specialist's (DPS) proprietary cleaning process thoroughly cleans DPFs, restoring them to nearly 90% or better of "new" condition.



How DPFs Work

In the diesel particulate matter filter, exhaust gasses pass through the open end of a channel and at the opposite end is a plug that forces the gases through the porous channel wall, allowing the exhaust to escape through the neighboring channel wall trapping as much as 90% of the solid particle matter.

Why DPF Maintenance Is Necessary

Unfortunately, many vehicle dealers imply that all that is needed to keep DPFs clean is to hit the vehicle's "regeneration" button. While it's true that the regen cycle is necessary and will combust much of the accumulated particulate matter, noncombustible materials trapped in the filter will still be left behind. This remaining residue creates back pressure that will eventually lead to increased regeneration down time, loss of horsepower, reduced fuel economy, filter damage and, ultimately, engine damage.

To properly clean the DPF it must be removed from the vehicle and put through a special cleaning process. Regens alone will not do the job.
