Abstract

L'invention concerne un dispositif permettant d'empêcher le calage d'un moteur. Ce dispositif comprend un détecteur 1 de la vitesse de rotation du moteur, un circuit 2 de mise en forme, un compteur 4 qui est remis à zéro chaque fois qu'il reçoit un signal d'horloge d'un générateur 3, une unité arithmetique 5 et un comparateur 6, pour comparer le signal correspondant à la vitesse du moteur à un signal lu dans une mémoire 7, et un circuit de sortie 8 pour commander une augmentation de l'admission d'air dans le moteur si la vitesse de rotation du moteur est inférieure à la vitesse lue dans la mémoire 7. L'invention concerne les dispositifs anti-calage de moteurs à combustion interne.The invention relates to a device for preventing stalling of an engine. This device comprises a detector 1 of the speed of rotation of the engine, a shaping circuit 2, a counter 4 which is reset to zero each time it receives a clock signal from a generator 3, an arithmetic unit 5 and a comparator 6, for comparing the signal corresponding to the engine speed with a signal read from a memory 7, and an output circuit 8 for controlling an increase in the air intake in the engine if the speed of rotation engine speed is less than the speed read in memory 7. The invention relates to anti-stall devices for internal combustion engines.
