Engine system having intake conduit with surge inhibitor and method

摘要

An engine system includes a plurality of turbochargers each including a compressor outlet fluidly connected to an intake manifold of an engine. A plurality of intake conduits are configured to each convey incoming combustion air to one of the turbochargers, and each includes a casing, and a duct within the casing having a surge inhibitor mounted thereon which includes a flow-directing surface oriented obliquely to an axis of the duct to direct combustion air leaked back out of the compressor inlet away from a discharging stream of combustion air exiting the duct. Related methodology is also disclosed.

1. An internal combustion engine system comprising:
an internal combustion engine including an intake manifold and an exhaust manifold; a turbocharger including a turbocharger housing defining a compressor inlet, and a compressor outlet fluidly connected to the intake manifold; an intake conduit configured to convey incoming combustion air to the turbocharger; the intake conduit including a casing, and a duct within the casing and defining a longitudinal axis extending between a combustion air inlet, and a combustion air outlet within the casing and axially spaced from the compressor inlet such that the duct discharges a stream of the incoming combustion air through the casing and toward the compressor inlet; and the intake conduit further including a surge inhibitor having a flow directing surface mounted to the duct, the flow-directing surface being oriented obliquely to the longitudinal axis to direct combustion air leaked back out of the compressor inlet away from the discharging stream.
