Abstract

La présente invention concerne un dispositif d'injection de carburant à mode de démarrage commutable. Ce dispositif utilise pour chaque cylindre un clapet d'injecteur actionné électromagnétiquement 28 commandé par la sortie d'un générateur d'impulsions de largeur variable 24. Chaque générateur d'impulsions 24 comprend un circuit de décharge à résistance-capacité et une thermistance unique 34 commune à tous les génerateurs 24. Cette thermistance est connectée aux circuits RC des générateurs selon une première configuration de circuit au cours du démarrage du moteur, pour fournir une large gamme de taux d'alimentation en carburant et selon une seconde configuration de circuit au cours du fonctionnement normal, les divers circuits étant alors isolés les uns des autres. La commutation entre les modes est déterminée par un commutateur de mode 36 commuté par un signal de démarrage en provenance d'un circuit 38. Application à la diminution de la pollution créée par les moteurs à explosion.
