Abstract

L'invention permet de discerner la combustion normale de la combustion anormale liée au cliquetis, et de prendre les mesures correctives nécessaires. Dans un cylindre d'un moteur sont disposés deux senseurs de température, l'un dans une zone proche de la bougie, l'autre dans une zone plus éloignée. Ces senseurs génèrent des signaux dont la différence est utilisée pour déceler le cliquetis : lorsqu'elle excède une certaine valeur, un signal est émis et/ou le système d'allumage peut recevoir un ordre de réduction de l'angle d'avance jusqu'à ce que les conditions sans cliquetis soient rétablies. L'invention s'applique aux moteurs à combustion interne (à allumage commandé) fixes ou pour véhicules quelconques.
