AN EXHAUST SYSTEM FOR FILTERING PARTICULATES FROM DIESEL ENGINE EXHAUST IN A PARTICULATE FILTER

摘要

An exhaust system that processes exhaust generated by an engine is provided. The system includes: a particulate filter (PF) that is disposed downstream of the engine and that filters particulates from the exhaust; and a grid that includes electrically resistive material that is segmented by non- conductive material into a plurality of zones and wherein the grid is applied to an exterior upstream surface of the PF.
