Abstract
A method of controlling fuel injection timing in a compression ignition engine including at least one cylinder. The method includes monitoring a parameter indicative of a commanded operating speed of the engine corresponding to an engine throttle notch and monitoring a parameter indicative of the actual operating speed of the engine. When the commanded engine speed exceeds the actual engine speed, the fuel injection timing for the engine may be advanced to reduce emissions.
