Title (EN) ENGINE CONTROL DEVICE
(FR) DISPOSITIF DE COMMANDE DE MOTEUR
(JA) エンジンの制御装置
Abstract:
(EN) An engine control device that has: a turbocharger 4; an EGR device 26 that comprises an EGR passage 27, an EGR valve 29, and an EGR cooler 28; and a PCM 60 that, on the basis of the operation state of an engine 10, controls the EGR valve 29 so as to adjust an EGR rate that is the ratio of the amount of an EGR gas to the total amount of gas that is introduced to a cylinder of the engine 10. The PCM 60: controls the EGR valve 29 such that, in a high load range R11 for the engine, the EGR device 26 makes the EGR gas reflux into an intake passage 1; and, in operation ranges for the engine 10 in which the EGR device 26 makes the EGR gas reflux, controls the EGR valve 29 such that the EGR rate increases to the extent that engine speed increases at the same engine load.
(FR) La présente invention concerne un dispositif de commande de moteur qui comporte : un turbocompresseur (4); un dispositif de RGE (26) qui comprend un passage de RGE (27), une soupape de RGE (29), et un dispositif de refroidissement de RGE (28); et un PCM (60) qui, sur la base de l'état de fonctionnement d'un moteur (10), commande la soupape de RGE (29) de manière à ajuster un taux de RGE qui est le rapport de la quantité de gaz de RGE sur la quantité totale de gaz qui est introduit dans un cylindre du moteur (10). Le PCM (60) : commande la soupape de RGE (29) de telle sorte que, dans une plage de charge élevée (R11) pour le moteur, le dispositif de RGE (26) entraîne le reflux de gaz de RGE dans un passage d'admission (1); et, dans les plages de fonctionnement pour le moteur (10) où le dispositif de RGE (26) entraîne le reflux de gaz de RGE, commande la soupape de RGE (29) afin que le taux de RGE augmente jusqu'à ce que le régime moteur augmente à la même charge de moteur.
(JA) エンジンの制御装置は、ターボ過給機4と、EGR通路27、EGRバルブ29及びEGRクーラ28を備えるEGR装置26と、エンジン10の運転状態に基づいて、エンジン10の気筒に導入される全ガス量に対するEGRガス量の割合であるEGR率を調整するようにEGRバルブ29を制御するPCM60と、を有し、このPCM60は、エンジンの高負荷域R11において、EGR装置26によってEGRガスを吸気通路1に還流させるようにEGRバルブ29を制御し、EGR装置26によってEGRガスを還流させるエンジン10の運転領域では、同一のエンジン負荷において、エンジン回転数が大きくなるほど、EGR率を大きくするようにEGRバルブ29を制御する。
