To provide a vehicle intake system which enables adjustment of an air intake amount while decreasing a temperature of intake air supplied to an engine and also enables discharge of foreign objects included in outer air with a simple structure.SOLUTION: A vehicle intake system 10 includes a first intake passage part 20 having a first intake port 22 provided at a downstream side of a grille 6 at a vehicle front part and a foreign object discharge port 26. Further, the vehicle intake system 10 includes a second intake passage part 30 having a closable door 34 which is controlled to be opened or closed by a control part 40 and a second intake port 32 provided at a downstream side of the first intake port 22 relative to the grille 6. In the first intake passage part 20, an inner wall surface corresponding to the foreign object discharge port 26 has inclination that changes a route of a part of the intake air from the first intake port 22 to cause the intake air to flow from the foreign object discharge port 26 to the second intake port 32. The control part 40 causes the closable door 34 to be in a closed state when a vehicle is in an operation state in which discharge of the foreign objects from the foreign object discharge port 26 is estimated.SELECTED DRAWING: Figure 1

    【課題】車両用の吸気装置において、簡単な構造で、エンジンへ供給する吸気の温度を低くしながら、吸気量を調整でき、外気に含まれる異物の排出も可能とすることである。【解決手段】車両用の吸気装置10は、車両前部のグリル6の下流側に設けられた第一吸気口22を有し、異物排出口26を有する第一吸気通路部20を備える。また、制御部40によって開閉制御される開閉扉34を有し、グリル6に対し第一吸気口22よりも下流側に設けられた第二吸気口32を有する第二吸気通路部30を備える。第一吸気通路部20は、異物排出口26に対応する内壁面が、第一吸気口22からの吸気の一部の進路を変更させ異物排出口26から第二吸気口32に向かわせる傾斜を有する。制御部40は、車両の運行状況が異物排出口26から異物の排出が推定される場合に、開閉扉34を閉状態とする。【選択図】図1
