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 comprising the steps of: calculating a post-warm-up steady-state port wall deposit quantity (a) (S100); calculating a shared-injection steady-state port wall deposit quantity (b) based on port wall deposit quantity (a) (S110); calculating a difference (c) in one cycle of shared-injection steady-state port wall deposit quantity (b) (S120); making a correction considering an engine temperature and an engine speed to calculate a transition correction quantity (d) (S130); and converting transition correction quantity (d) into a wave form representing temporal transition to make a wall deposit correction with higher priority on a port injection quantity (S140).
(FR) Selon cette invention, une ECU d'un moteur exécute un programme comprenant les étapes consistant à calculer une quantité de dépôt sur les parois de port à l'état permanent après réchauffage (a) (S100), à calculer une quantité de dépôt sur les parois de port à l'état permanent d'injection partagée (b) en fonction de la quantité (a) de dépôt sur les parois de port (S110), à calculer la différence (c) dans un cycle de quantité de dépôt sur les parois de port à l'état permanent d'injection partagée (b) (S120), à effectuer une correction en tenant compte de la température du moteur et de la vitesse du moteur pour calculer un quantité de correction de transition (d) (S130), à convertir cette quantité de correction de transition (d) en une forme d'onde représentant une transition temporelle pour effectuer une correction de dépôt sur les parois avec une priorité supérieure sur une certaine quantité d'injection (S140).
