Title
(EN) CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE
(FR) APPAREIL DE COMMANDE POUR MOTEUR A COMBUSTION INTERNE
Abstract
(EN) An engine ECU executes a program including the steps of: determining presence of abnormality in a low-pressure fuel system (S100); ceasing an intake manifold injector when determination is made of abnormality in the low-pressure fuel system (YES at S100); increasing the target purge rate (S130) when the engine operation state attains an injection partaking state between an in-cylinder injector and an intake manifold injector (YES at S120); reducing the VVT overlap (S140); and retarding the ignition timing (S150).
(FR) L'invention porte sur une unité de commande électronique (ECU) de moteur qui exécute un programme en plusieurs étapes consistant à déterminer la présence d'une anomalie dans un système de carburant à basse pression (S100) ; à arrêter l'injecteur collecteur d'admission lorsqu'une anomalie est repérée dans le système de carburant à basse pression (OUI à S100) ; à augmenter la vitesse de purge cible (S130) lorsque l'état de fonctionnement du moteur atteint un état de partage d'injection entre un injecteur dans le cylindre et un injecteur collecteur d'admission (OUI à S120) ; à réduire le chevauchement de réglage de distribution variable (VVT) (S140) ; et à retarder la séquence d'allumage (S150).
