Title
(EN) COMBUSTION CONTROL DEVICE
(FR) DISPOSITIF DE COMMANDE DE COMBUSTION
(JA) 燃焼制御装置
Abstract
(EN)
A combustion control device (28) equipped with: injectors (5) that inject fuel into the combustion chamber of an engine; an electronic control unit (24) configured so as to operate the injectors (5) such that fuel is injected at least twice; and a temperature sensor (27) that detects the temperature of the intake air drawn into the combustion chamber, or the outside air temperature. The electronic control unit (24) obtains the engine load and, on the basis of the obtained engine load, determines the fuel injection amount and the fuel injection timing for the two or more fuel injections. When the intake air temperature or the outside air temperature detected by the temperature sensor (27) is higher than a prescribed temperature the electronic control unit (24) reduces the fuel injection amount for the second determined fuel injection in accordance with the intake air temperature or the outside air temperature.
(FR)
L'invention porte sur un dispositif de commande de combustion (28) comportant : des injecteurs (5) qui injectent du carburant dans la chambre de combustion d'un moteur ; une unité de commande électronique (24) conçue pour commander les injecteurs (5) de telle sorte que du carburant est injecté au moins deux fois ; et un capteur de température (27) qui détecte la température de l'air d'admission aspiré dans la chambre de combustion, ou la température de l'air extérieur. L'unité de commande électronique (24) obtient la charge de moteur et, sur la base de la charge de moteur obtenue, détermine la quantité d'injection de carburant et le calage d'injection de carburant pour les deux ou plusieurs injections de carburant. Lorsque la température d'air d'admission ou la température d'air extérieur détectée par le capteur de température (27) est supérieure à une température prescrite, l'unité de commande électronique (24) réduit la quantité d'injection de carburant pour la seconde injection de carburant déterminée en fonction de la température d'air d'admission ou de la température d'air extérieur.

 燃焼制御装置28は、エンジンの燃焼室内に燃料を噴射するインジェクタ5と、燃料を少なくとも2回に分けて噴射させるようにインジェクタ5を操作するように構成された電子制御ユニット24と、燃焼室内への吸気温度又は外気温度を検出する温度センサ27と、を備える。電子制御ユニット24は、エンジンの負荷を取得して、取得したエンジンの負荷に基づいて、少なくとも2回の燃料噴射の燃料噴射量及び燃料噴射時期を決定する。電子制御ユニット24は、温度センサ27により検出された吸気温度又は外気温度が所定温度よりも高いときに、吸気温度又は外気温度に応じて、決定された2回目の燃料噴射の燃料噴射量を減量する。
