Title (EN) INTERNAL COMBUSTION ENGINE CONTROL DEVICE AND CONTROL METHOD
(FR) DISPOSITIF DE COMMANDE ET PROCÉDÉ DE COMMANDE DE MOTEUR À COMBUSTION INTERNE
(JA) 内燃機関の制御装置および制御方法
Abstract:
(EN) Provided are an internal combustion engine control device and control method in which a multi-injection process comprises performing an intake synchronized injection and an intake asynchronous injection to inject a required injection amount (Qd) of fuel by operating a port injection valve (16) for injecting fuel into an intake passageway (12). A variable process includes variably setting an injection timing (Is) for the intake synchronized injection on the basis of at least two of three parameters. The injection timing for the intake synchronized injection is expressed by the rotation angle of a crank shaft (28) of an internal combustion engine (10). The three parameters include a rotational speed (NE) of the crank shaft of the internal combustion engine, a valve-opening start timing (DIN, AEs) of an intake valve (18), and a temperature (THW) of an intake system of the internal combustion engine (10).
(FR) L'invention concerne un dispositif de commande et un procédé de commande de moteur à combustion interne dans lesquels un processus d'injection multiple comprend la réalisation d'une injection synchronisée d'admission et d'une injection asynchrone d'admission pour injecter une quantité d'injection requise (Qd) de carburant en actionnant une vanne d'injection d'orifice (16) pour injecter du carburant dans un passage d'admission (12). Un processus variable comprend le réglage variable d'une base de temps d'injection (Is) pour l'injection synchronisée d'admission en se basant sur au moins deux paramètres parmi trois. La base de temps d'injection pour l'injection synchronisée d'admission est exprimée par l'angle de rotation d'un vilebrequin (28) d'un moteur à combustion interne (10). Les trois paramètres comprennent une vitesse de rotation (NE) du vilebrequin du moteur à combustion interne, une base de temps de début d'ouverture de soupape (DIN, AEs) d'une soupape d'admission (18) et une température (THW) d'un système d'admission du moteur à combustion interne (10).
(JA) マルチ噴射処理は、吸気通路(12)に燃料を噴射するポート噴射弁(16)を操作することで、要求噴射量(Qd)の燃料を噴射すべく、吸気同期噴射と吸気非同期噴射とを実行する。可変処理は、吸気同期噴射の噴射時期(Is)を、3つのパラメータのうちの少なくとも2つのパラメータに基づき可変設定する。吸気同期噴射の噴射時期は内燃機関(10)のクランクシャフト(28)の回転角度で表現される。3つのパラメータは、内燃機関のクランクシャフトの回転速度(NE)、吸気バルブ(18)の開弁開始時期(DIN、AEs)、および内燃機関(10)の吸気系の温度(THW)である。
