。[Claims for Utility Model Registration] An intake system for an engine equipped with a throttle valve that throttles the amount of intake air and independent intake passages of different lengths for independently introducing intake air into each cylinder downstream of the throttle valve. In addition to providing an auxiliary intake passage that bypasses intake air from the upstream side of the throttle valve to each independent intake passage, the length of the auxiliary intake passage is made shorter or the cross-sectional area becomes larger as the auxiliary intake passage communicates with the longer independent intake passage. An engine intake system characterized by:
