What is a DPF?

A diesel particulate filter (or DPF) is a device designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine that could be otherwise harmful to the environment & humans alike.

A DPF or Diesel Particulate Filter is a part within the exhaust system of diesel engines that removes diesel particulate matter or soot (the black stuff that comes out of the exhaust) from the exhaust gas as it flows out of the engine.
The device looks like a big metal container with metal pipes coming out of either end. Inside the DPF are special metals that look like a grate. As exhaust gas flows through the grate soot is left behind. Overtime, or due to incorrect oils or maintenance, your car, truck or van’s DPF can become blocked causing expensive problems.

Diesel particulate filters usually remove 85% or more of the carbon build up in your exhaust and under certain conditions can even remove almost 100% of soot.

DPF’s are designed to burn off the accumulated particulate, either passively, through the use of a catalyst or actively by using a fuel burner which heats the filter to soot combustion temperatures. Active methods to do DPF burn offs are programmed into your engine’s management system by the Manufacturer. When your engine management system recognizes that your DPF is full exhaust temperatures will be raised to burn off the excessive soot build up on the DPF. Some burn off systems also use an extra fuel injector whereby they inject fuel into the exhaust stream, when the fuel enters the stream it ignites burning off the accumulated soot which is then converted into ash.  Unfortunately the systems designed to keep your DPF clean and unblocked can be unreliable, ineffective and damaged by poor or incorrect maintenance.

Failure of fuel injectors or turbochargers can result in contamination of your DPF with raw diesel or engine oil thereby damaging the DPF.

Why DPF’s are important

Lynx Auto Services knows a damaged DPF will lead to performance inefficiency and if the DPF becomes blocked could lead to catastrophic engine failure. In addition to being bad for your vehicle, DPF’s are important to protect you and your family from harmful exhaust gases and ensure that your vehicle is in compliance with environmental laws.

Diesel particulate filter cleaning is also required as part of periodic maintenance.

Failed DPF regeneration(Don't ignore the warnings)

The normal DPF regeneration process occurs in your vehicle at road speeds higher than usual city traffic speed. Vehicles driven exclusively at low speeds in urban traffic can therefore require DPF regeneration more frequently because they do not travel at speeds high enough for DPF regeneration to occur.

When DPF regeneration fails a warning light will come on in your vehicles dash. If you ignore the engine warning light that comes on when your DPF cannot be cleaned and wait too long to have your DPF regenerated or cleaned, it may damage the DPF resulting in lowered fuel economy, sluggish engine performance, destroying the diesel particulate filter and even damaging your diesel engine.

In Australia, the average cost for replacement of a DPF for a passenger vehicle is anywhere between $4000.00 and $6000.00. At Lynx Auto Services we use the latest cleaning process that will help restore your DPF and maintain the health of your vehicle for a fraction of the price of a replacement.
