ABSTRACT:
A system is provided for regenerating an exhaust gas aftertreatment component of an internal combustion engine. The system is operable to determine an output torque of the engine, and to supply a single quantity of fuel to the engine after combustion of a main quantity of fuel if the output torque is greater than a torque threshold, and to otherwise supply a first quantity of fuel to the engine near an end of combustion of the main quantity of fuel followed by supplying a second quantity of fuel after combustion of the main quantity of fuel.
