ンジンの吸気装置。[Scope of claim for utility model registration] A high-load intake passage equipped with an on-off valve that closes during low-load operation and opens during high-load operation, and a low-load intake passage that branches off from the high-load intake passage upstream of the on-off valve. In an engine intake system in which a fuel injection valve is arranged in a high-load intake passage downstream of an on-off valve, the intake system is located immediately upstream of the tip of the fuel injection valve when the upper edge of the on-off valve is closed. An intake system for an engine, characterized in that the rotational shaft of the on-off valve is located downstream of the upper edge.
