吸気装置。 A multi-cylinder engine is equipped with a low-load intake port and a high-load intake port that open into each combustion chamber, and a high-load intake passage leading to the high-load port is provided with a control valve that closes at low load. In the intake system, high-load intake ports of adjacent cylinders are arranged at positions adjacent to each other, and the high-load intake ports are communicated with each other by a communication passage near an intake valve. Intake device.
