燃機関の吸気装置。 An intake system for a multi-cylinder internal combustion engine, in which a communication pipe is fixed to a plurality of throttle bodies with bolts to connect the throttle bodies to each other, and the connection pipe is formed with a communication passage that communicates the insides of the throttle bodies with each other. In the multi-cylinder internal combustion engine, the bolt extends through the communication passage, and a sealing mechanism is provided between the bolt and the communication pipe to shut off the communication passage and the atmosphere. Intake device.
