Abstract
(EN)
An internal combustion engine (1) for a vehicle is equipped with a variable compression ratio mechanism (2) capable of changing the mechanical compression ratio. An idle stop, which is for automatically stopping the internal combustion engine (1) when the vehicle stops, and a sailing stop, which is for stopping the internal combustion engine (1) in conjunction with the release of a forward clutch (8) during inertial travel, are carried out. A target compression ratio during normal travel is set on the basis of the load and rotation speed of the internal combustion engine (1). During an idle stop the target compression ratio is set to an idle stop restart compression ratio (εis). During a sailing stop the target compression ratio is set to a sailing stop restart compression ratio (εss). The sailing stop restart compression ratio (εss) is lower than the idle stop restart compression ratio (εis).

L'invention concerne un moteur à combustion interne (1) pour un véhicule qui est équipé d'un mécanisme à taux de compression variable (2) capable de modifier le taux de compression mécanique. Un arrêt au ralenti, qui est destiné à arrêter automatiquement le moteur à combustion interne (1) lorsque le véhicule s'arrête, et un arrêt de voyage, qui est destiné à arrêter le moteur à combustion interne (1) en conjonction avec le débrayage d'un embrayage de marche avant (8) pendant le déplacement inertiel, sont effectués. Un taux de compression cible pendant un déplacement normal est réglé sur la base de la charge et de la vitesse de rotation du moteur à combustion interne (1). Pendant un arrêt au ralenti, le taux de compression cible est réglé sur un taux de compression de redémarrage d'arrêt au ralenti (εis). Pendant un arrêt de voyage, le taux de compression cible est réglé sur un taux de compression de redémarrage d'arrêt de voyage (εss). Le taux de compression de redémarrage d'arrêt de voyage (εss) est inférieur au taux de compression de redémarrage d'arrêt au ralenti (εis).

車両用の内燃機関(1)は、機械的圧縮比を変更可能な可変圧縮比機構(2)を備える。車両停止時に内燃機関(1)を自動停止するアイドルストップと、惰行走行中にフォワードクラッチ(8)の開放を伴って内燃機関(1)を停止するセ一リングストップと、が行われる。通常走行中の目標圧縮比は、内燃機関(1)の負荷と回転速度とに基づいて設定される。アイドルストップ時には、目標圧縮比がアイドルストップ再始動用圧縮比(εis)に設定される。セ一リングストップ時には、目標圧縮比がセ一リングストップ再始動用圧縮比(εss)に設定される。セ一リングストップ再始動用圧縮比(εss)はアイドルストップ再始動用圧縮比(εis)よりも低い。
