Abstract (en)

The method of starting a motor vehicle involves using an electronic control circuit (6) to reduce the fuel injection rate and retard the ignition when the starter is first used. The engine parameters and manifold (2) pressure to preset levels. The starter motor (10) is cut after a set interval.

Abstract (fr)

Pour son lancement, le moteur à combustion interne est couplé à une machine électrique (10) et alimenté en air par l'intermédiaire d'un collecteur d'admission (2) muni d'un organe (4) de réglage de débit d'air motorisé. Selon l'invention, à la suite d'un ordre de démarrage, on commande la machine électrique (10) pour qu'elle délivre sa puissance totale disponible, l'organe (4) de réglage de débit et l'avance à l'allumage (6) étant à des positions minimales. Pendant la rotation de la machine électrique, on compare le régime à un seuil de régime et la pression dans le collecteur d'admission (2) à un seuil de pression. Du carburant est injecté dès que les conditions conjuguées suivantes sont satisfaites: le seuil de régime est franchi vers le haut et le seuil de pression est franchi vers le bas. Puis, on coupe la machine électrique (10) . Ensuite, on régule les paramètres de fonctionnement du moteur pour établir son régime de ralenti. <IMAGE>
