Abstract

L'invention concerne généralement un système de commande de moteur à combustion interne, permettant de faire fonctionner le moteur soit sur le nombre total de cylindres, soit sur un nombre partiel de cylindres. Le système comprend une unité 12 de commande d'injection de carburant, un convertisseur fréquence-tension 20 donnant un signal représentant la vitesse du moteur, une source 28 de tensions de référence, des comparateurs 30, 32 et un circuit bistable 40 permettant de rendre actifs ou inactifs un certain nombre de cylindres du moteur. L'invention concerne les moteurs à combustion interne de véhicule automobile.The invention generally relates to an internal combustion engine control system for operating the engine either on the total number of cylinders or on a partial number of cylinders. The system comprises a fuel injection control unit 12, a frequency-voltage converter 20 giving a signal representing the speed of the engine, a source 28 of reference voltages, comparators 30, 32 and a bistable circuit 40 for rendering active or inactive a number of engine cylinders. The invention relates to internal combustion engines of motor vehicles.
