Title (EN) INTERNAL COMBUSTION ENGINE CONTROL DEVICE
(FR) DISPOSITIF DE COMMANDE DE MOTEUR À COMBUSTION INTERNE
(JA) 内燃機関制御装置
Abstract:
(EN) The purpose of the present invention is to reduce fuel consumption by making a correction per cycle upon predicting a change in combustion limit caused by cycle-to-cycle variation in temperature and EGR rate. To this end, the internal combustion engine control device for controlling an internal combustion engine comprising a cylinder and an exhaust pipe is characterized by comprising a control unit which performs EGR control for returning exhaust gas in the exhaust pipe into the cylinder, whereby the control unit obtains an in-cylinder gas temperature and an EGR rate in a state in which both an intake valve and an exhaust valve are closed in a combustion cycle, and corrects a combustion parameter to be used in the same combustion cycle as the aforementioned combustion cycle on the basis of the obtained gas temperature and the EGR rate.
(FR) La présente invention a pour objet de réduire la consommation de carburant en réalisant une correction par cycle lors de la prédiction d'un changement de limite de combustion provoqué par une variation de cycle à cycle en température et en taux de recirculation des gaz d'échappement. A cet effet, le dispositif de commande de moteur à combustion interne pour la commande d'un moteur à combustion interne comprenant un cylindre et un tuyau d'échappement est caractérisé en ce qu'il comprend une unité de commande qui effectue une commande de recirculation des gaz d'échappement (EGR) pour renvoyer les gaz d'échappement dans le tuyau d'échappement dans le cylindre, l'unité de commande obtenant de ce fait une température de gaz dans le cylindre et un taux d'EGR dans un état dans lequel à la fois une soupape d'admission et une soupape d'échappement sont fermées dans un cycle de combustion, et corrigeant un paramètre de combustion à utiliser dans le même cycle de combustion que le cycle de combustion susmentionné sur la base de la température du gaz obtenue et du taux d'EGR.
(JA) 本発明の目的は、温度およびEGR率のサイクルばらつきによる、燃焼限界の変化を予測し、サイクル毎に補正を行い、燃焼消費量を減少させることである。そのため、シリンダと排気管とを備えた内燃機関を制御する内燃機関制御装置において、前記排気管の排気ガスを前記シリンダの筒内に戻すように制御するEGR制御を行い、燃焼サイクルにおいて吸気バルブ及び排気バルブの双方が閉じている状態における筒内のガスの温度とEGR率とを求め、この求めたガスの温度とEGR率に基づいて前記燃焼サイクルと同じ燃焼サイクルにおける燃焼パラメータを補正する制御部を備えたことを特徴とする。
