The development of new designs of a diesel particulate control system is discussed herein. The system employs a single high collection efficiency ceramic monolith to filter the particulate emissions of the engine. Regeneration is achieved by intermittent pulses of pressurized reverse-flow air. After every regeneration the soot is collected at the bottom of the device where it is burned in an incinerator chamber. Different configurations of the system were tested satisfactorily for performance and durability for 100 hrs, coupled to a small experimental engine which was sooting at high rates. Subsequently, a system incorporating a long ventless chamber fitted with an electric burner was mounted on a diesel passenger car and tested for on-road performance evaluation and further development.
