摘要： A particular trap is regenerated without the use of heat. The regeneration is accomplished using a valving mechanism for periodically creating a reverse pressure throughout the entire trap, after the reverse pressure is created controls are operative to start a regeneration cycle by creating a substantially instantaneous reverse pressure drop across the porous walls of the entire trap to dislodge accumulated particulate cake and by causing the filtered exhaust gas to flow back through the porous walls to remove the dislodged particulate from the trap. A settling tank is connected to the exhaust pipe upstream of the trap to receive and store the dislodged particulate. The controls are operative to return the system to its filtering operation. Gaseous effluent from the tank is returned to the exhaust system upstream of the filter to provide a "closed system" in which only filter gas is discharged to atmosphere.
