ABSTRACT:
A method of controlling the combustion of a compression ignition engine is disclosed having applications for diesel engine combustion control for CAI.The method comprises determining setpoint values for physical parameters linked with the intake of gaseous oxidizer in the combustion chamber, and a setpoint value (θinj)reffor the crank angle at which a fuel has to be injected into the combustion chamber. While the engine control system controls actuators so that the values of the physical parameters are equal to the setpoint values, setpoint value (θinj)refis corrected before the physical parameters reach their setpoint values. Angle CAy is controlled to be equal to a reference value for an optimized combustion while accounting for differences between the real values of the physical parameters and the setpoint values of these parameters and keeps the optimum combustion by fuel injection with the corrected setpoint value.
