Title (EN) CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE
(FR) APPAREIL DE COMMANDE POUR MOTEUR À COMBUSTION INTERNE
(JA) 内燃機関の制御装置
Abstract:
(EN) The present invention relates to a control apparatus for an internal combustion engine which implements coordinated control of the quantity of EGR gas supplied by an exhaust gas recirculation (EGR) apparatus and the quantity of supercharging by a supercharger equipped with a variable flow rate mechanism. In particular, the control apparatus is characterized in being provided with: a state quantity estimation section (77) that calculates the excess oxygen factor in the cylinders on the basis of the operation state of the internal combustion engine; and a switching means (81) for switching the opening angle commands for the opening angle of the EGR valve and the opening angle of the variable flow rate mechanism of the supercharger when the internal combustion engine is determined to be in a state of transition on the basis of the excess oxygen factor, such that the opening angles of the EGR valve and the variable flow rate mechanism are smaller than normal.
(FR) La présente invention concerne un appareil de commande pour un moteur à combustion interne qui met en œuvre une commande coordonnée de la quantité de gaz EGR fourni par un appareil de recirculation de gaz d'échappement (EGR) et la quantité de suralimentation par un compresseur équipé d'un mécanisme de débit variable. En particulier, l'appareil de commande est caractérisé en étant doté de : une section d'estimation de quantité d'état (77) qui calcule le facteur d'oxygène en excès dans les cylindres sur la base de l'état de fonctionnement du moteur à combustion interne; et un moyen de commutation (81) pour la commutation des commandes d'angle d'ouverture pour l'angle d'ouverture de la soupape EGR et l'angle d'ouverture du mécanisme de débit variable du compresseur lorsque le moteur à combustion interne est déterminé de façon à être dans un état de transition sur la base du facteur d'oxygène en excès, tels que les angles d'ouverture de la soupape EGR et le mécanisme de débit variable sont plus petits que la normale.
(JA) 本発明は排気ガス再循環(EGR)装置によるEGRガス供給量と可変流量機構付き過給機の過給量とを協調制御する内燃機関の制御装置に関する。特に、内燃機関の運転状態に基づいて筒内酸素過剰率を算出する状態量推定演算部(77)と、該算出した筒内酸素過剰率に基づいて内燃機関が過渡状態にあると判定された場合に、EGRバルブの開度及び過給機に備えられた可変流量機構の開度が平常状態に比べて小さくなるように、それぞれの開度指令を切り換える切換手段(81)を備えたことを特徴とする。
