To provide a supercharging device for an engine, capable of securing a function of a supercharger during its cold time.SOLUTION: A supercharging device for an engine includes: a travel wind control valve (8) capable of introducing travel wind into an engine room of a vehicle; a supercharger (2) provided in an intake passage of the engine; a drive part for driving the supercharger (2); and a control part (13) for controlling the travel wind control valve (8) and the driving part, the control part (13) serving for controlling the driving part so as to drive the supercharger (2) when an operation state is in a supercharging region and to stop driving of the supercharger (2) when the operation state is in a non-supercharging region. The control part (13) controls the travel wind control valve (8) to a closing side when the wall temperature of the supercharger (2) is lower than a first set temperature T1, and controls the travel wind control valve (8) to a closing side when the wall temperature of the supercharger (2) is lower than a second set temperature T2 set lower than the first set temperature T1, and causes the driving part to execute forcible drive control of the supercharger (2) even when the operation state of the engine is in the non-supercharging region.SELECTED DRAWING: Figure 1

    【課題】冷間時における過給機の機能を確保可能なエンジンの過給装置を提供する。【解決手段】車両のエンジンルーム内への走行風を導入可能な走行風制御弁(8)と、エンジンの吸気通路に設けた過給機(2)と、この過給機(2)を駆動する駆動部と、走行風制御弁(8)と駆動部を制御する制御部(13)であって運転状態が過給領域にあるときに過給機(2)を駆動し且つ運転状態が非過給領域のときに過給機(2)の駆動を停止するように駆動部を制御する制御部(13)とを備えたエンジンの過給装置において、前記制御部(13)は、過給機(2)の壁温が第1設定温度T1よりも低い時は走行風制御弁(8)を閉じ側に制御し、過給機(2)の壁温が第1設定温度T1よりも低く設定された第2設定温度T2よりも低い時は走行風制御弁(8)を閉じ側に制御すると共に、エンジンの運転状態が非過給領域にあるときであっても駆動部に過給機(2)の強制駆動制御を実行させる。【選択図】図1
