Title (EN) FUEL INJECTION SYSTEM
(FR) SYSTEME D'INJECTION DE CARBURANT
Abstract:
(EN) Fuel injection system with an enriched mixture for acceleration and a leaner mixture for deceleration, in which the transition compensation is determined by the throttle valve variation speed as a function of throttle valve travel during variation. Measurement of the throttle valve position determines the cause of the variation in the air flow, with the result that information concerning a change in the operating state is more readily available, and consequently the enriched mixture or leaner mixture can also be more rapidly provided. In addition, an intermediate jet threshold system is incorporated which when exceeded initiates an intermediate jet calculation.
(FR) Système d'injection de carburant avec un mélange enrichi pour l'accélération et un mélange plus pauvre pour la décélération, dans lequel la compensation de transition est déterminée par la vitesse de variation de la vanne papillon en fonction de la course de ladite vanne pendant la variation. La mesure de la position de la vanne papillon détermine la cause de la variation de la quantité d'air, de sorte que l'on obtient plus rapidement des informations relatives à une modification dans l'état de fonctionnement, et par voie de conséquence il est également possible de fournir plus rapidement le mélange enrichi ou le mélange appauvri. En outre, pour l'enregistrement du mélange, un système de seuil à jet intermédiaire est incorporé qui, lorsque ce seuil est dépassé, déclenche le calcul d'un jet intermédiaire.
