Title (EN) EXHAUST GAS PURIFICATION SYSTEM IN INTERNAL COMBUSTION ENGINE
(FR) SYSTÈME DE PURIFICATION DE GAZ D’ÉCHAPPEMENT D’UN MOTEUR À COMBUSTION INTERNE
(JA) 内燃機関の排気浄化システム
Abstract:
(EN) This invention provides an exhaust gas purification system in an internal combustion engine provided with an exhaust gas purification device comprising a catalyst having an oxidation capability, which exhaust gas purification system is a technique capable of raising the temperature of the catalyst more rapidly. When the temperature of the catalyst is raised to an active temperature, an exhaust gas flow rate control valve is controlled in a valve closing direction and, at the same time, the intake airflow control valve is controlled in a valve opening direction (S102). The temperature of the exhaust gas discharged from the internal combustion engine is raised by providing the lag angle in fuel injection timing in the internal combustion engine (S105, S109).
(FR) La présente invention concerne un système de purification de gaz d’échappement d’un moteur à combustion interne doté d’un dispositif de purification de gaz d’échappement qui comprend un catalyseur ayant une capacité d’oxydation, le système de purification de gaz d’échappement correspondant à une technique qui permet d’augmenter plus rapidement la température du catalyseur. Lorsque la température du catalyseur est augmentée jusqu’à une température active, un clapet de commande du taux du débit des gaz d’échappement est commandé dans une direction de fermeture du clapet et, simultanément, le clapet de commande du débit d’air d’admission est commandé dans une direction d’ouverture du clapet (S102). La température des gaz d’échappement émis par le moteur à combustion interne est augmentée par le biais de l’angle de traînée dans la synchronisation de l’injection de carburant dans le moteur à combustion interne (S105, S109).
(JA) 本発明は、酸化機能を有する触媒を含んで構成される排気浄化装置を備えた内燃機関の排気浄化システムにおいて、触媒をより速やかに昇温させることが可能な技術を提供することを課題とする。本発明では、触媒を活性温度にまで昇温させるときに、排気流量制御弁を閉弁方向に制御すると共に吸入空気量制御弁を開弁方向に制御する(S102)。そして、さらに、内燃機関における燃料噴射時期を遅角することで機関排出排気を昇温させる(S105、S109)。
