Method and apparatus for regulating a bypass flow of a supercharged internal combustion engine

摘要

A method and apparatus for regulating a bypass flow of a turbocharged internal combustion engine is disclosed. A first preferred embodiment of the apparatus includes an air receiver which is in fluid communication with a turbocharger and an air oscillation pipe. The air oscillation pipe is in fluid communication with an inlet manifold, which inlet manifold is in fluid communication with a bypass duct and the turbocharged engine. The bypass duct is in fluid communication with the turbocharger. Pressure pulsations emanating from the engine propagate into the inlet manifold and the air oscillation pipe causing an air column within the inlet manifold and air oscillation pipe to oscillate. Periodic oscillations of the air column produces periodic pressure differences across the bypass duct, facilitating a bypass flow of air through the bypass duct.
