Title (EN) METHOD AND DEVICE FOR CONTROLLING INTERNAL COMBUSTION ENGINE
(FR) PROCÉDÉ ET DISPOSITIF PERMETTANT DE COMMANDER UN MOTEUR À COMBUSTION INTERNE
(JA) 内燃機関の制御方法及び制御装置
Abstract:
(EN) In this method for controlling an internal combustion engine, an air-fuel mixture which has an air-fuel ratio leaner than a theoretical air-fuel ratio is formed in a cylinder by a first fuel injection, and while a low-temperature oxidation reaction is taking place in the air-fuel mixture during a compression stroke, a second fuel injection is carried out to inject fuel toward the vicinity of a discharge channel of an ignition plug, and following the second fuel injection, spark ignition of the fuel injected by the second fuel injection is carried out by a spark plug when a spark discharge from the spark plug is able to reach the fuel.
(FR) La présente invention concerne un procédé permettant de commander un moteur à combustion interne selon lequel un mélange air-carburant qui présente un rapport air-carburant plus pauvre qu'un rapport air-carburant théorique, est formé dans un cylindre par une première injection de carburant et, pendant qu'une réaction d'oxydation à basse température a lieu dans le mélange air-carburant pendant une course de compression, une seconde injection de carburant est réalisée pour injecter du carburant à proximité d'un canal de décharge d'une bougie d'allumage, et après la seconde injection de carburant, un allumage par étincelle du carburant injecté par la seconde injection de carburant est réalisé par une bougie d'allumage lorsqu'une décharge d'étincelle de la bougie d'allumage peut atteindre le carburant.
(JA) 内燃機関の制御方法は、第1燃料噴射により筒内に理論空燃比よりもリーンな混合気を形成し、混合気が圧縮行程において低温酸化反応を起こしている期間中に、点火プラグの放電チャンネル近傍に向けて燃料を噴射する第2燃料噴射を行い、第2燃料噴射の後、第2燃料噴射で噴射された燃料に点火プラグの火花が届くタイミングで点火プラグによる火花点火を行う。
