Title (EN) CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
(FR) DISPOSITIF DE CONTRÔLE POUR UN MOTEUR À COMBUSTION INTERNE
(JA) 内燃機関の制御装置
Abstract:
(EN) The minimum value for the degree of opening of a wastegate valve (24), wherein the flow volume of exhaust air flowing via a wastegate port (22) when the degree of opening of the wastegate valve (24) is changed toward the open side stops increasing, is defined as a first prescribed degree of opening. An electronic control device (50) controls the degree of opening of the wastegate valve (24) on the basis of the engine operating state, and when the vehicle is running steadily at a high speed, that is, when the degree of opening of the wastegate valve (24) which has been set on the basis of the engine operating state is equal to or greater than the first prescribed degree of opening, the degree of opening of the wastegate valve (24) is varied between values equal to or greater than the first prescribed degree of opening.
(FR) La valeur minimale pour le degré d'ouverture d'une soupape de décharge (24), dans laquelle le volume d'écoulement de l'air d'échappement qui s'écoule par un orifice de décharge (22) quand le degré d'ouverture de la soupape de décharge (24) est changé vers le côté ouvert, arrête d'augmenter, est définie comme un premier degré d'ouverture prescrit. Un dispositif de contrôle électronique (50) contrôle le degré d'ouverture de la soupape de décharge (24) sur la base de l'état de fonctionnement du moteur, et quand le véhicule fonctionne de manière stable à grande vitesse, à savoir, quand le degré d'ouverture de la soupape de décharge (24) qui a été établi sur la base de l'état de fonctionnement du moteur est égal ou supérieur au premier degré d'ouverture prescrit, le degré d'ouverture de la soupape de décharge (24) varie entre des valeurs égales ou supérieures au premier degré d'ouverture prescrit.
(JA)  ウェイストゲートバルブ(24)の開度を開き側に変化させた際にウェイストゲートポート(22)を介して流れる排気の流量が増大しなくなる同ウェイストゲートバルブ(24)の開度の最小値を第1所定開度と定義する。電子制御装置(50)は機関運転状態に基づきウェイストゲートバルブ(24)の開度を制御する一方、車両が高速定常走行中であるときには、すなわち機関運転状態に基づき設定されるウェイストゲートバルブ(24)の開度が第1所定開度以上とされるときには、ウェイストゲートバルブ(24)の開度を同第1所定開度以上において変動させる。
