Diesel Particulate Filters (DPF’s) remove particulate matter, such as soot and ash, from diesel engine exhausts. DPF’s are known as ‘particulate traps’ and consist of numerous small channels in a porous ceramic material.
When the exhaust gas passes through the filter’s inlet channels, it’s forced through the porous walls of the filter before emerging from the outlet channels. The particulate matter is then trapped when the exhaust passes through these channel walls, removing up to 99% of the particulate matter in the exhaust flow.
