TLDR
In this article, an air bypass valve installed in the air bypass conduit is opened and the compressed air downstream of the throttle valve is returned to the upstream of the turbocharger compressor to suppress occurrence of a surging at the turbocharging compressor.Abstract:
An internal combustion engine with a dual turbocharger system includes an air bypass conduit connecting a downstream portion of a first turbocharger compressor with an upstream portion of a second turbocharger compressor so that the length of the air bypass conduit is relatively long. When a throttle is rapidly closed, an air bypass valve installed in the air bypass conduit is opened and the compressed air downstream of the throttle valve is returned to the upstream of the turbocharger compressor to suppress occurrence of a surging at the turbocharger compressor. Since the air bypass conduit is relatively long, the compressed and circulated air is effectively cooled when flowing through the air bypass conduit and melting of an impeller of the turbocharger compressor is prevented.read more
