  • Apparatus and method for reducing flow noise in a commercial engine vehicle
    Patent number: 10047667
    Abstract: An apparatus for reducing flow noise in a commercial engine vehicle includes an actuator into which first compressed air generated according to operation of an accelerator pedal and second pressed air generated from an air tank of a vehicle are selectively introduced. The apparatus also includes a lift plate moving up and down in the actuator by a pressure of the first or second compressed air introduced thereinto. The apparatus also includes a waste gate valve operated by a pressure according to the up and down movement of the lift plate in the actuator, in order to bypass exhaust gas in a turbine when the waste gate valve is opened.
