エンジンの吸気装置。 A main intake passage whose downstream end opens into the combustion chamber of the cylinder and is equipped with an intake valve at the opening, and which is equipped with a control valve in the middle of the passage that closes during low load, and whose upstream end is downstream of the throttle valve and which is equipped with the control valve. opens into the main intake passage upstream of the control valve, and the downstream side opens into the main intake passage downstream of the control valve and immediately upstream of the intake valve,
In an engine intake system having a sub-intake passage whose downstream end opening is oriented in the tangential direction of the cylinder, the upstream end of the inner circumferential side of the cylinder of the sub-intake passage is upstream of the outer circumferential side of the cylinder. An intake device for an engine, characterized in that an opening on the upstream end side of the sub-intake passage is formed so as to open into the main intake passage at a position upstream from the end.
