To provide an internal combustion engine intake duct capable of preventing water from entering into an internal combustion engine when a vehicle travels in a deep puddle, and supplying low-temperature air to the internal combustion engine when the vehicle is in normal traveling operation.SOLUTION: In an intake duct 6, a downstream side duct section 12 is attached at a position deviated to the left side of an upstream side duct section 11, and an air exhaust port 11e for exhausting air to the rear from the upstream side duct section 11 is installed on the right side of the upstream side duct section 11. The downstream side duct section 12 has a downstream side air intake port 12b which is open toward the right side. The downstream side air intake port 12b is installed close to the air exhaust port 11e of the upstream side duct section 11.SELECTED DRAWING: Figure 5

    【課題】車両が水深の深い水溜りを走行する際に、内燃機関に水が吸入されることを防止でき、かつ、車両の通常走行時に低温の空気を内燃機関に供給できる内燃機関の吸気ダクトを提供すること。【解決手段】吸気ダクト6において、下流側ダクト部12は、上流側ダクト部11の左方側に偏った位置に取付けられており、上流側ダクト部11の右方側に、上流側ダクト部11から後方に空気を排出する空気排出口11eが設けられている。下流側ダクト部12は、右方に開口する下流側空気取入口12bを有し、下流側空気取入口12bは、上流側ダクト部11の空気排出口11eの近傍に設けられている。【選択図】図5
