Claims

[Scope of utility model registration request]

A deflection plate is rotatably supported on the inner wall surface of one side of the intake port, and a deflection air passage is formed between the inner wall surface of the other side of the intake port opposite to the inner wall surface of the one side and the downstream end of the deflection plate. In the intake air control device, the downstream end of the deflection plate that forms the deflection air passage is made of a material that deforms depending on temperature, and deforms when cold, so that the inner wall surface on the one side of the intake port An intake control device for a fuel-injected internal combustion engine, characterized in that the air intake control device has a shape that approaches that of a fuel-injected internal combustion engine.
