Abstract

L'invention porte sur un procédé de détermination d'une sensibilité anormale d'un moteur à allumage commandé à une apparition de phénomènes de pré-allumage sporadiques à faible régime engendrant une combustion prématurée et non désirée d'une partie du mélange de carburant dans le moteur, caractérisé en ce qu'il est effectué un calcul d'une fréquence (3) de phénomènes de pré-allumage sur une distance calibrable A pour chaque cylindre du moteur et, quand la fréquence est supérieure à au moins un seuil (S1 à Sx) calibrable, il est conclu à une sensibilité anormale du moteur vis-à-vis de phénomènes de pré-allumage et cette fréquence est mémorisée.The invention relates to a method for determining an abnormal sensitivity of a spark-ignition engine to an occurrence of sporadic, low-speed pre-ignition phenomena causing premature and unwanted combustion of a portion of the fuel mixture in the invention. the engine, characterized in that a calculation is made of a frequency (3) of pre-ignition phenomena over a calibratable distance A for each cylinder of the engine and, when the frequency is greater than at least one threshold (S1 at Sx) calibratable, it is concluded that the engine is abnormally sensitive to pre-ignition phenomena and this frequency is stored.
