Abstract (en)
[origin: WO2017144789A1] The invention relates mainly to a method for controlling the combustion of a combustion engine, characterized in that said method comprises: - a step of detecting abnormal combustion generating vibrations in a cylinder, known as "knocking", said vibrations having a frequency of between 600 Hz and 1200 Hz, - a step of calculating a load limitation depending notably, in a speed/load map, on an iso-probability curve (C1) of the occurrence of knocking following said detection, and - a step of applying said load limitation so as to cause said combustion engine to operate in the speed/load map at operating points minimizing the risk of knocking occurring.
