Apparatus and method for flow generated noise reduction of vehicle engine

摘要

The present invention is characterized in that the first compressed air generated in accordance with the operation of the accelerator pedal and the second compressed air generated from the hydraulic pressure generator installed in the commercial engine are selectively introduced, and the first compressed air or the second compressed air is introduced The actuator being operated by a pressure generated by the lifting and lowering of the lifting plate to open the actuator and a waste gate for bypassing the exhaust gas on the turbine side through the opening of the actuator, Valve.
