PROBLEM TO BE SOLVED: To provide an intake passage structure of a vehicular internal combustion engine which can prevent easily water penetration into an internal combustion engine while a vehicle travels on a flooding road.SOLUTION: An intake duct part 10 for introducing outside air into an engine is provided at the vehicular width direction outside of a shroud, and the intake duct part 10 is formed at the side wall 9C of the shroud. There are included an intake port 9c which makes a space 12 surrounded by a bumper, the shroud, and a heat exchanger communicate with the intake duct part 10, and an intake port 11f which is formed at a partition plate 11F and communicates with an engine room excluding the space 12. And, the intake duct part 10 is configured to include an opening-closing plate 13 which is provided as rotatable with a rotation axis 14 extending in the vehicular longitudinal direction as the center and is rotatable between a first rotation position at that the intake port 9c is opened and the intake port 11f is closed and a second rotation position at that the intake port 9c is closed and the intake port 11f is opened.SELECTED DRAWING: Figure 5
【課題】車両が冠水路を走行中に内燃機関に水が侵入することを容易に防止できる車両用内燃機関の吸気通路構造を提供すること。【解決手段】シュラウドの車幅方向外方に、エンジンに外気を導入する吸気ダクト部10を備え、吸気ダクト部10が、シュラウドの側壁9Cに形成され、バンパ、シュラウドおよび熱交換器に囲まれる空間12と吸気ダクト部10とを連通する吸気口9cと、仕切板11Fに形成され、空間12を除いたエンジンルームに連通する吸気口11fとを有する。さらに、吸気ダクト部10が、車両の前後方向に延びる回転軸14を中心に回転自在に設けられ、吸気口9cを開放し、かつ、吸気口11fを閉止する第1の回転位置と、吸気口9cを閉止し、かつ吸気口11fを開放する第2の回転位置との間で回転自在な開閉板13を含んで構成される。【選択図】図5
