Abstract
A method of controlling the combustion of a spark-ignition engine having application to gasoline engines is disclosed. An engine control system controls actuators so that the values of physical parameters linked with the combustion of a mixture of gas and fuel in a combustion chamber are equal to their setpoint values, to optimize the combustion. A setpoint value is determined for an ignition crank angle of the fuel mixture which is then corrected before the physical parameters reach their setpoint values. A correction to be applied to this ignition angle setpoint value is calculated so that the crank angle CAis equal to its setpoint value. Finally, the engine control system controls the ignition of the mixture in the combustion chamber when the crank angle is equal to the corrected setpoint value to optimize combustion.
