What is a Diesel Particulate filter (DPF)?
The Diesel Particulate Filter (DPF) is a device fitted to the exhaust system of a vehicle to remove diesel particulate matter (soot) from the exhaust gas. Soot is a by-product of the diesel combustion process and without the use of a DPF the soot particles would be emitted into our environment.The entire filter system consists of a pre catalytic converter, an oxidising catalytic converter and a DPF. The pre catalytic converter is installed in the exhaust gas flow, very close to the engine. The oxidising catalytic converter and the DPF form a single unit and are housed further downstream in the exhaust gas flow. For monitoring and diagnostic purposes, the system contains exhaust gas temperature sensors and a differential pressure sensor. The DPF consists of a ceramic core made of silicon carbide with alternately closed channels. The exhaust gas flows into the closed channels and is forced through the channel walls and out of the ceramic core. The filtered exhaust gas flows into the rest
