Patent ID: 7562649

Claim:
A method of controlling fuel delivered to a diesel engine, comprising: storing a first base map that defines values for control of an air handling actuator in terms of engine speed and acceleration pedal position; storing a second base map that defines values for control of a fueling parameter in terms of engine speed and intake manifold pressure; storing a correction map that defines values for a correction factor in terms of intake manifold pressure and combustion temperature; wherein the combustion temperature is determined on the basis of at least one or more of the following correction factors: coolant temperature, intake manifold temperature, and intake manifold oxygen concentration; receiving values representing pedal position and engine speed; in response to the preceding step, using the first base map to determine at least one air handling actuator control value; receiving values representing the intake manifold pressure and at least one of the correction factors; and in response to the preceding step, calculating the combustion temperature, and using the second base map and the correction map to generate at least one fueling control value.
