Title (EN) INTERNAL COMBUSTION ENGINE CONTROLLER
(FR) CONTROLEUR DE MOTEUR A COMBUSTION INTERNE
Abstract:
(EN) An engine ECU executes a program including: the step of outputting a fuel-cut instruction (S200) when conditions that an accelerator position PA is not higher than a threshold value and a rate of increase DNE of engine speed NE is not lower than a determination value DNE(0) are satisfied (YES at S100); the step of fully closing throttle opening (S300); and the step of suspending ignition of air-fuel mixture by a spark plug (S500).
(FR) Une ECU du moteur exécute un programme qui comprend: le stade d'émission d'une commande de coupure de carburant (S200), lorsque les conditions sont réunies (YES at S100) pour qu'une position d'accélérateur ne dépasse pas une valeur de seuil et qu'une vitesse d'augmentation DNE de la vitesse NE du moteur ne soit pas inférieure à une valeur de détermination DNE(0); le stade de fermeture complète de l'ouverture des gaz (S300); et le stade d'interruption d'allumage du mélange air-carburant par une bougie d'allumage (S500).
