OSTI ID:6188741
In an engine system including an internal combustion engine and an exhaust turbine supercharger, a valve stop mechanism is provided to stop the throttle valve of the engine in an angular position anterior to the idle position thereof when the throttle valve is suddenly moved toward the idle position in the presence of an air pressure higher than a predetermined value in the air induction passageway of the engine downstream of the compressor unit of the supercharger and upstream of the throttle valve of the engine so as to preclude production of pressure surges in exhaust turbine supercharger.
