DIESEL PARTICULATE FILTER COMPRISING A FINELY DISPERSED DIESEL PARTICULATE CATALYST

摘要

The invention relates to a device for the, (in particular continuous), oxidation of particulates from the exhaust gases of diesel motors. Said devi ce consists of an open-pored body as a particle filter, on whose surface an oxidation catalyst is finely dispersed. The device is characterised in that from an exhaust gas temperature as low as 150 ~C, the catalyst causes the oxidation of particulates attached to the filter using the residual oxygen o f the exhaust gas, thus keeping the filter body continuously free of particulates during almost all the operating conditions of the motor.
