可変吸気装置。[Scope of Claim for Utility Model Registration] Two intake pipes are provided in the engine intake system, one for low speed and one for high speed, with different lengths and diameters, and the flow of intake air is blocked in the intake pipe for high speed. Equipped with an intake control valve, in the low-to-medium speed range, the intake control valve is closed and intake air is introduced into the cylinder from the long intake pipe side for low speeds, and in the high speed range, the intake control valve is opened and both intakes are In a variable intake system that controls intake air to be introduced into a cylinder from a pipe, intake air is allowed to flow in the intake pipe in the intake pipe for low speeds, but intake air is allowed to flow in the opposite direction. A variable intake system for an engine, characterized by being provided with a reed valve that operates to prevent backflow.
