Abstract
(EN)
An engine system (1) is provided with an engine ECU (10), a shutoff valve (163) capable of shutting off an EGR passage (16), and a temperature sensor (42) for detecting the temperature of an exhaust gas purification device (30), and shuts off the EGR passage (16) by the shutoff valve (163) when the temperature of the exhaust gas purification device (30) is less than a predetermined threshold value. Further, the engine system (1) increases the fuel injection quantity of an injector (17) while decreasing the valve opening of a diesel throttle (19) in response to the increase of the quantity of flow of exhaust gas into a turbocharger (14) when the output of an engine (100) is less than a predetermined value. Meanwhile, when the output of the engine (100) is the predetermined value or more, the opening of a variable nozzle vane mechanism (141) of the turbocharger (14) is increased.

L'invention porte sur un système de moteur (1) qui est équipé d'une ECU de moteur (10), d'une vanne d'arrêt (1463) apte à fermer un passage d'EGR (recirculation des gaz d'échappement) (16) et d'un détecteur de température (42) destiné à détecter la température d'un dispositif d'épuration des gaz d'échappement (30), et qui ferme le passage d'EGR (16) au moyen de la vanne d'arrêt (163) lorsque la température du dispositif d'épuration des gaz d'échappement (30) est inférieure à une valeur de seuil prédéterminée. En outre, le système de moteur (1) accroît la quantité d'injection de carburant d'un injecteur (17) en même temps qu'il réduit l'ouverture d'une commande d'alimentation diesel (19) en réponse à l'accroissement du débit des gaz d'échappement d'un turbocompresseur (14) lorsque la sortie du moteur (100) est inférieure à une valeur prédéterminée. Entretemps, lorsque la sortie du moteur (100) est à la valeur prédéterminée ou plus, l'ouverture du mécanisme de vanne de buse variable (141) du turbocompresseur (14) est augmentée.

 エンジンシステム1は、エンジンECU10と、EGR通路16を遮断可能な遮断弁163と、排気浄化装置30の温度を検出する温度センサ42と、を備え、排気浄化装置30の温度が所定のしきい値未満の場合に、遮断弁163によってEGR通路16を遮断する。更に、エンジンシステム1は、エンジン100の出力が所定値未満の場合に、ターボチャージャ14への排ガスの流入量の増大に応じてディーゼルスロットル19の弁開度を小さくしつつインジェクタ17の燃料噴射量を増大させる。一方、エンジン100の出力が所定値以上の場合は、ターボチャージャ14の可変ノズルベーン機構141の開度を大きくする。
