の負圧取出構造。 In a V-type engine in which an intake collecting passage is arranged between banks, and a shutter valve that closes at low load is interposed in the independent intake passage of each cylinder that branches from the intake collecting passage, each of the intake collecting passages below the intake collecting passage A vacuum chamber communicating with the independent intake passage downstream of the shutter valve is provided in the interbank space located between the independent intake passages, and intake negative pressure for operating the actuator is taken out through the vacuum chamber. Features a negative pressure extraction structure for V-type engines.
