Abstract

L'invention concerne les moteurs à combustion interne. Elle a pour objet un dispositif de détection des pré-allumages éventuels, qui comprend un circuit 32, 33, 34, 35 indiquant si le mélange présent entre les électrodes 19, 23 de l'une des bougies est ionisé, donc est en combustion, et fournissant un signal qui n'est appliqué à un étage de signalisation 44 qu'en l'absence d'un signal sur le fil 42 traduisant l'existence d'une étincelle d'allumage entre lesdites électrodes. Application à la détection des préallumages sur les moteurs de véhicules automobiles.
