Method for controlling the combustion of a spark-ignition engine by controlling combustion phasing

摘要

The method involves correcting a setpoint value of an ignition crank angle before physical parameters linked with combustion of a gas and fuel mixture in a combustion chamber reach setpoint values, by calculating correction to be applied such that a crank angle is equal to the setpoint value of the ignition crank angle for an optimized combustion. Ignition of the mixture in the chamber is controlled by an engine control system when the crank angle is equal to the corrected setpoint value of the ignition crank angle to optimize combustion.
