ABSTRACT:
A construction of an intake passage for an internal combustion engine in which a length of the intake passage is automatically varied in response to a variation in the cross-sectional area of the intake passage. The intake passage is provided for supplying intake air to an intake port of the engine. A first intake pipe has a first end connected to the intake port of the internal combustion engine. A second intake pipe is movably connected to the first intake pipe. The second intake pipe has an open end protruding from a second end of the first intake pipe so as to introduce air therethrough to the first intake pipe. A cross-sectional area of the second intake pipe gradually increases toward the open end. A projection protrudes into an interior of the second intake pipe through the open end.
