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 introduced to a cylinder of the engine 10. The PCM 60: controls the EGR valve 29 such that, in a high load range R11 and a middle load range R12 for the engine 10, the EGR device 26 makes the EGR gas reflux into an intake passage 1; and controls the EGR valve 29 such that the EGR rate is lower in the high load range R11 than in the middle load range R12 at the same engine speed.
(FR) Dispositif de commande de moteur qui comporte : un turbocompresseur 4; un dispositif EGR 26 qui comprend un passage EGR 27, un clapet EGR 29 et un refroidisseur EGR 28; et un PCM 60 qui, sur la base de l'état de fonctionnement d'un moteur 10, commande le clapet EGR 29 de manière à régler un taux d'EGR qui est le rapport de la quantité de gaz EGR sur la quantité totale de gaz introduit dans un cylindre du moteur 10. Le PCM 60 : commande le clapet EGR 29 de telle sorte que, dans une plage de charge élevée R11 et une plage de charge moyenne R12 pour le moteur 10, le dispositif EGR 26 entraîne le reflux de gaz EGR dans un passage d'admission 1; et commande le clapet EGR 29 de telle sorte que le taux d'EGR est plus faible dans la plage de charge élevée R11 que dans la plage de charge moyenne R12 à la même vitesse 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10の高負荷域R11及び中負荷域R12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、同一のエンジン回転数において、高負荷域R11では中負荷域R12よりもEGR率が小さくなるようにEGRバルブ29を制御する。
