Abstract

Système et procédé d'injection de combustible pour un moteur à combustion interne ayant au moins un injecteur de combustible décalé contrôlé et un unique injecteur de combustible ajusté contrôlé. Système dans lequel les injecteurs décalés produisent une quantité constante de combustible en étant excités par une impulsion de durée fixe durant chaque cycle d'injection, tandis que la différence entre la quantité constante et une quantité désirée de combustible calculée à partir d'un planning d'injection de combustible est fournie par l'injecteur ajusté, le planning d'injection de combustible étant déterminé depuis des paramètres de fonctionnement du moteur par un planificateur électronique qui procure en outre des impulsions de cadencement destinées à déclencher le début du cycle d'injection. Système applicable aux moteurs d'automobiles.
