Abstract
The invention is a method of controlling the combustion of a diesel engine comprising determining setpoint values for physical parameters linked with the intake of gaseous oxidizer in the combustion chamber, and a setpoint value θfor the crank angle at which fuel has to be injected into the combustion chamber. While the engine control system controls actuators in such a way that the values of the physical parameters are equal to the setpoint values, setpoint value θis corrected before the physical parameters reach their setpoint values, by accounting for the differences between the real values of the physical parameters and the setpoint values of these parameters. Finally, the engine control system controls fuel injection into the combustion chamber when the crank angle is equal to this corrected setpoint value θin order to keep combustion optimal.
