Patent

CA 2501402

An apparatus for and method of providing improved engine performance during a change in engine load conditions reduces or eliminates engine stumbling or hesitation and/or reduces emissions levels. When an engine load change is detected (201), a compensation factor for fuel injection timing is determined (205) and combined with a base timing for fuel injection, thereby altering fuel injector timing during the transition period.

L'invention concerne un appareil et un procédé permettant d'obtenir des performances améliorées d'un moteur pendant le changement d'états de la charge du moteur, de manière à réduire ou éliminer le trou dans la carburation ou l'hésitation du moteur et/ou à réduire les niveaux d'émissions. Quand un changement de la charge du moteur est détecté (201), un facteur de compensation destiné à l'avance à l'injection du carburant est déterminé (205) et combiné à une avance de base destinée à l'injection du carburant, modifiant ainsi l'avance à l'injection du carburant pendant la période de transition.
