Abstract
An internal combustion engine is coupled to an oxidation catalyst disposed upstream of a second catalytic device. A controller includes an instruction set executable to detect a cold start engine starting event, monitor first and second temperature sensors, control each of the fuel injectors to execute a first set of fuel injection events for each cylinder event in response to an output torque request, and execute a second set of fuel injection events for each cylinder event after cylinder top-dead-center. The second set of fuel injection events includes a final injection event, and a duration of the final injection event is determined based upon the first and second temperatures.
