Abstract
Dispositif de dosage du carburant pour un moteur à combustion interne équipé d'un dispositif d'injection et à allumage indépendant, avec un appareil de commande (17) produisant au moins en fonction de la vitesse de rotation (12) du moteur à combustion interne des impulsions d'injection destinées aux soupapes d'injection, une commutation (19) s'opérant pour une commande des soupapes d'injection au moyen des impulsions d'injection dérivées de l'installation d'allumage (15) du moteur à combustion interne en cas de perturbation de l'appareil de commande. La commutation peut s'effectuer soit par le retrait de la prise centrale de l'appareil de commande, soit par une détection automatique d'erreur au moyen d'un relais de vitesse de rotation.Fuel metering device for an internal combustion engine equipped with an injection and independent ignition device, with a control unit (17) producing at least as a function of the rotational speed (12) of the internal combustion engine injection pulses for the injection valves, switching (19) taking place to control the injection valves by means of injection pulses derived from the ignition system (15) of the combustion engine internal in the event of a disturbance to the control unit. Switching can take place either by removing the central plug from the control unit or by automatic error detection by means of a speed relay.
