PROBLEM TO BE SOLVED: To provide a motorcycle engine intake system capable of enhancing responsiveness to a change in an amount of intake air flowing into a supercharger through an intake control valve.SOLUTION: A supercharger 42 of a motorcycle is driven by power of a crank shaft 26 of an engine E and compresses intake air I to be sent to the engine E. The supercharger 42 has a centrifugal type impeller 60 and an intake control valve 69 at an upstream side of the impeller 60. The intake control valve 69 is arranged opposite to an intake port 46 of the supercharger 42 with respect to an intake air flow direction, adjusts an amount of the intake air I flowing into the impeller 60 and causes the intake air I flowing thereinto to have prerotation.SELECTED DRAWING: Figure 2

    【課題】吸気制御弁による過給機への吸気流入量の変化に対する応答性を高めることができる自動二輪車のエンジン吸気システムを提供する。【解決手段】自動二輪車の過給機42は、エンジンEのクランク軸26の動力により駆動され、エンジンEへの吸気Iを圧縮する。過給機42は遠心式のインペラ60を有し、過給機42のインペラ60の上流側に吸気制御弁69が配置されている。吸気制御弁69は、吸気の流れ方向に関して過給機42の吸込口46に対向配置されている。吸気制御弁69は、インペラ60への吸気Iの流入量を調整するとともに、インペラ60に流入する吸気Iに予旋回を与える。【選択図】図2
