摘要:
A diesel particulate collector (10) based on the principles of inertial impaction, virtual impaction, and filtration, for controlling exhaust emissions (12) from a diesel internal combustion engine (14) includes a housing (16) having a first plate (24) with a plurality of nozzles (26) directing exhaust flow therethrough, a first impactor (28) causing particle separation and a change of flow direction, a second plate (30) having a second set of nozzles (32) directing exhaust flow therethrough, and a second impactor (34) causing particle separation and a change of flow direction, in a first of multiple stages in a sequential cascaded separation and collection system.
