DPF  Diesel Particulate Filter

A Diesel Particulate Filter is a device designed to reduce the emissions from diesel fuelled vehicles. The filter, traps particulate matter (soot) which it then when full, reduces to ash during regeneration. Regeneration is controlled by the correct driving cycle of the vehicle and its engine management system. Faults that occur with a vehicle can cause the DPF to become blocked or damaged and then regeneration is not possible.

DPF Regeneration
Over time soot builds up inside the filter increasingly blocking the Diesel Particulate Filter. Unfortunately when the DPF reaches about 80% soot saturation (this varies based on manufacturer), regeneration is no longer possible. This occurs if there are other mechanical issues which can affect the DPF, but also when poor quality or incorrect engine oil is used, when poor quality or incorrect fuel is used, or even if the vehicle is only used over short distances.

To avoid your Diesel Particulate Filter becoming blocked due to short driving trips, Ecotech Auto has the latest equipment which enables us to access your vehicle’s engine management system and perform a forced DPF Regeneration. If the soot accumulation is not too high we can do an electronic regeneration. The electronic regeneration is done by raising the temperature of the exhaust gas up to 700 degrees Celsius enough to burn off the soot accumulation.

DPF Cleaning
If the DPF is too full, we can do a chemical cleaning which helps to reduce the soot emissions generated by your engine, regenerate the Diesel Particulate Filter and clean away any existing soot particles.

DPF Filter Replacement
After time the filter efficiency will decease until regeneration will not be effective and the DPF filter cannot be cleaned anymore at this stage the particulate filter will need replaced. Having regular cleans will allow regeneration to take place and it will extend the life of the filter, however eventually with high mileage a Disel Particulate Filter replacement will be necessary.
