Title (EN) DIESEL ENGINE FOR SHIP
(FR) MOTEUR DIESEL POUR NAVIRE
(JA) 舶用ディーゼルエンジン
Abstract:
(EN) Provided is a diesel engine for a ship in which an engine body can be operated under more favorable conditions. This diesel engine has: an engine body; a supercharger; an EGR system; an engine control device that controls the driving of the engine body, and controls the action of an exhaust valve in a combustion cycle on the basis of an exhaust valve closing timing pattern in which the timing of closing the exhaust valve comes later as the speed of the engine body increases; and an EGR control device. The exhaust valve closing timing pattern is such that the timing at which an operating condition of the engine body is a threshold value condition and the exhaust valve is closed while the EGR system is running is earlier than the timing at which the operating condition of the engine body is a threshold value condition and the exhaust valve is closed while the EGR system has stopped.
(FR) L'invention concerne un moteur diesel pour un navire dans lequel un corps de moteur peut être actionné dans des conditions plus favorables. Ce moteur diesel comporte : un corps de moteur ; un compresseur de suralimentation ; un système EGR ; un dispositif de commande de moteur qui commande l'entraînement du corps de moteur, et commande l'action d'une soupape d'échappement dans un cycle de combustion sur la base d'un modèle de synchronisation de fermeture de soupape d'échappement dans lequel la synchronisation de fermeture de la soupape d'échappement provient plus tard lorsque la vitesse du corps de moteur augmente ; et un dispositif de commande d'EGR. Le motif de synchronisation de fermeture de soupape d'échappement est tel que le moment auquel une condition de fonctionnement du corps de moteur est une condition de valeur seuil et la soupape d'échappement est fermée alors que le système EGR est en marche est antérieur au moment auquel la condition de fonctionnement du corps de moteur est une condition de valeur seuil et la soupape d'échappement est fermée alors que le système EGR est arrêté.
(JA) エンジン本体をより良い条件で運転させることができる舶用ディーゼルエンジンを提供する。エンジン本体と、過給機と、EGRシステムと、エンジン本体の駆動を制御し、エンジン本体の回転数が高くなるにしたがって、燃焼サイクルにおける排気弁を閉じるタイミングが遅くなる排気弁閉タイミングパターンに基づいて、排気弁の動作を制御するエンジン制御装置と、EGR制御装置と、を有し、排気弁閉タイミングパターンは、エンジン本体の運転条件が閾値条件であり、EGRシステムが稼動している場合の排気弁を閉じるタイミングが、エンジン本体の運転条件が閾値条件であり、EGRシステムが停止している場合の排気弁を閉じるタイミングよりも、早い。
