Title (EN) INTERNAL-COMBUSTION ENGINE CONTROL METHOD AND CONTROL DEVICE
(FR) PROCÉDÉ DE COMMANDE ET DISPOSITIF DE COMMANDE DE MOTEUR À COMBUSTION INTERNE
(JA) 内燃機関の制御方法および制御装置
Abstract:
(EN) An internal-combustion engine (1) includes a variable compression ratio mechanism (2) for changing a mechanical compression ratio, and a variable valve timing mechanism (7) for changing the valve timing of an intake valve (4). When acceleration is demanded, a target compression ratio is set to a lower compression ratio than the target value in a normal condition, and the valve timing is set to the advance angle side. Since the allowable combustion pressure decreases in a prescribed intermediate compression ratio region, if an actual compression ratio (rVCR) exists in the prescribed intermediate compression ratio region in the course of a compression ratio change accompanying acceleration, the variable compression ratio mechanism (2) restricts the intake pressure by increasing a degree of opening of a wastegate valve (29) or reducing a degree of opening of a throttle valve (19), for example.
(FR) L'invention concerne un moteur à combustion interne (1), lequel moteur comprend un mécanisme à taux de compression variable (2) pour changer un taux de compression mécanique, et un mécanisme de calage de distribution variable (7) pour changer de calage de distribution d'une soupape d'admission (4). Quand une accélération est demandée, un taux de compression cible est établi à un taux de compression inférieur à la valeur cible dans une condition normale, et de calage de distribution est réglé sur le côté d'angle d'avance. Comme la pression de combustion admissible diminue dans une région de taux de compression intermédiaire prescrit, si un taux de compression effectif (rTCV) existe dans la région de taux de compression intermédiaire prescrit au cours d'un changement de taux de compression accompagnant une accélération, le mécanisme à taux de compression variable (2) restreint la pression d'admission par l'augmentation d'un degré d'ouverture d'une vanne de décharge (29) ou par la réduction d'un degré d'ouverture d'un papillon (19), par exemple.
(JA) 内燃機関(1)は、機械的圧縮比を変更する可変圧縮比機構(2)と、吸気弁(4)のバルブタイミングを変更する可変バルブタイミング機構(7)と、を有する。加速要求時には、定常時の目標値よりも目標圧縮比を低圧縮比とし、バルブタイミングを進角側とする。可変圧縮比機構(2)は、所定の中間圧縮比領域で許容燃焼圧が低くなるので、加速に伴う圧縮比変化の過程の中で、所定の中間圧縮比領域に実圧縮比(rVCR)があるときに、ウェストゲートバルブ(29)の開度増加やスロットルバルブ(19)の開度減少等により吸気圧を制限する。
