Abstract
A system and method for controlling an engine in a hybrid vehicle based on the use of a calculated combustion stability value to modify a pulsewidth signal to fuel injectors of the engine to reduce hydrocarbon emissions, especially following an engine start. The calculated combustion stability value is determined as a function of a torque signal obtained from an electric motor of the hybrid vehicle.
