Operating method of this negative pressure generator and internal combustion piston engine having to load control, without the throttle valve, the negative pressure generating device

摘要

(57) [summary] The present invention relates to internal combustion piston engine equipped with a gas exchange valve. This gas exchange valve is fully variable control possible through the engine control unit (2), gas exchange valve can be connected to the air supply passage (4), this air supply passage, the air flowing therethrough and a device for generating negative pressure by utilizing energy portion (6), and a controllable means for adapting to changes in flow energy due to operation, the apparatus at least the device (6) It is connected to the negative cost one device in (8, 9, 10) at least through the negative pressure line of the one (7).
