PROBLEM TO BE SOLVED: To further increase safety while appropriately controlling a supercharging pressure.SOLUTION: In an engine with turbosupercharger, a first turbosupercharger 50 and a second turbosupercharger 60 are provided, and a bypass passage 132 for bypassing a first turbine 54 of the first turbosupercharger 50, a bypass valve 141 for opening/closing it, and a bypass valve driving device 142 for driving the bypass valve 141 are also provided. The turbosuperchargers 50, 60 are arranged in an engine room 100 formed at the front of a vehicle so that connection shafts 51, 61 on the rear side of an engine body 1 extend in the cross direction of the vehicle and the first turbosupercharger 50 is located under the second turbosupercharger 60, and a body part 142a of the bypass valve driving device 142 is arranged to protrude rearward from the first turbosupercharger 50 and overlap with the inside space of a floor tunnel 200 in a vehicle front view.SELECTED DRAWING: Figure 3
【課題】過給圧を適切に制御しつつ安全性をより高める。【解決手段】第1ターボ過給機50と第2ターボ過給機60とを設けるとともに、第1ターボ過給機50の第1タービン54をバイパスするバイパス通路132と、これを開閉するバイパス弁141と、バイパス弁141を駆動するバイパス弁駆動装置142とを設け、各ターボ過給機50,60をエンジン本体1の後方において各連結軸51,61が車幅方向に延び、かつ、第1ターボ過給機50が第2ターボ過給機60の下方となるように、車両の前部に形成されたエンジンルーム100に配置し、バイパス弁駆動装置142の本体部142aを、第1ターボ過給機50から後方に突出し、かつ、車両前方視でフロアトンネル200の内側空間と重複するように配置する。【選択図】図3
