What is a Diesel Particulate Filter? A Diesel Particulate Filter is a device fitted to a modern diesel vehicles exhaust system which filters particulate matter (PM) from exhaust gases.
DPF’s need to be emptied of trapped particulate matter regularly. This is done by a process called “regeneration” which involves burning the soot to gas at a very high temperature.
An underlying engine or fuel system fault, incorrect vehicle usage or lack of regeneration can cause an excessive build up of soot which subsequently affects vehicle performance and can lead to expensive repair costs. This has led to some vehicle owners removing the DPF entirely however, DPF removal has both social and legal implications.
“It is an offence under the Road vehicles (Construction and Use) Regulations (Regulation61a(3) to use a vehicle which has been modified in such a way that it no longer complies with the air pollutant emission standards it was designed to meet. Removal of the DPF will almost invariably contravene these requirements making the vehicle illegal for road use”
Historically DPF blockages have necessitated replacement of the unit; However Fuel Injection Services can now offer an alternative through our collaboration with Hartridge DPF cleaning solutions..
