装置。 In an engine intake path device comprising a collector of a predetermined volume upstream of an intake port of each cylinder, the collector has a downstream volume section where the intake port opens, and an upstream volume section where an intake port that guides intake air to the collector opens. A partition plate that can be divided into two parts is provided, and a communication path is provided that bypasses the partition plate and communicates the upstream volume part and the downstream volume part, so that the intake port and the intake port open into the same volume part. An intake path device for an engine, characterized in that it is provided with a control means for displacing a partition plate according to operating conditions.
