Regenerating vehicle exhaust gas particle filter by fitting heat proof electrical resistance across filter entry to ignite collected particles when excessive deposition is detected by temperature

摘要

An electrically conducting heat proof resistance (22) is located at the entry (15) to a particle filter box (30) and may be disposed as a straight line, circle or spiral. The resistance is energized from a control unit (26) using battery or alternator energy when the motor functioning point is suitable and the filter temperature indicates that there has been excessive particle accumulation in the filter.
