気装置。 A plurality of independent intake passages each independently connected to each cylinder of the engine are curved in the middle so that they face each other, and each of the independent intake passages is placed in a state where they face each other in a specific operating range in the opposing part. The intake system for an engine is provided with a control valve that communicates with the control valve in each of the intake passages. The upstream portion of the side passage portion is curved toward the control valve side, and the upstream passage portion is curved toward the control valve side with respect to the straight line connecting the confluence with the downstream passage portion and its upstream end. An intake device for an engine, characterized in that it is curved so as to bulge out in a substantially arc shape on the opposite side.
