DPFs, also known as ‘particulate traps', remove particulate matter from diesel engine exhausts. DPFs are becoming more common in trucks, buses and cars due to increasingly stringent international emissions regulations.
Diesel Particulate Filters are made up of an extruded matrix of channels; adjacent channels are blocked at alternate ends. This structure forces the exhaust gas to flow through the channel wall and this is how the particulate matter is trapped.
DPFs are used extensively to allow vehicles to meet the standards of Low Emission Zones and E-Zones in many major cities including London, Berlin, Amsterdam and Stockholm.
