ABSTRACT:
An apparatus controls the operation of a regenerative device for generating a quantity of heat to burn the exhaust particles collected in a trap located in the exhaust conduit of an internal combustion engine. The apparatus is responsive to the pressures on the inlet and outlet sides of the trap to detect a regeneration requirement to operate the regenerative device so as to regenerate the trap. The apparatus is also responsive to the engine speed and engine load to control the quantity of heat the regenerative device generates so as to maintain the inlet side of the trap at a target temperature during the regeneration period.
