Title (EN) SPARK-IGNITED INTERNAL COMBUSTION ENGINE
(FR) MOTEUR À COMBUSTION INTERNE À ALLUMAGE COMMANDÉ
(JA) 火花点火式内燃機関
Abstract: front page image
(EN)An internal combustion engine comprises a variable compression ratio mechanism (A) capable of varying the mechanical compression ratio and a variable valve timing mechanism (B) capable of controlling the closing timing of an intake valve (7). In a low-load operating range except an idling operation, the mechanical compression ratio is maintained at a maximum mechanical compression ratio, and in the idling operation, the mechanical compression ratio is lower than the maximum mechanical ratio.
(FR)L'invention concerne un moteur à combustion interne qui comprend un mécanisme à taux de compression variable (A) capable de faire varier le taux de compression mécanique et un mécanisme de réglage de distribution variable (B) capable de commander la temporisation de fermeture d'une soupape d'admission (7). Lors d'une plage de fonctionnement à faible charge, à l'exception d'un fonctionnement au ralenti, le taux de compression mécanique est maintenu à un taux de compression mécanique maximal, et dans le fonctionnement au ralenti, le taux de compression mécanique est inférieur au taux de compression mécanique maximal.
(JA)内燃機関において、機械圧縮比を変更可能な可変圧縮比機構(A)と、吸気弁(7)の閉弁時期を制御可能な可変バルブタイミング機構(B)とを具備する。機械圧縮比はアイドリング運転を除く低負荷運転領域において最大機械圧縮比とされ、アイドリング運転時には機械圧縮比が最大機械圧縮比よりも低くされる。
