摘要：In an internal combustion engine with a variable nozzle vane turbocharger, whenthe flow rate (VN passage flow rate) of exhaust gas passing through nozzle vanes has
reached a spatial resonance region in an exhaust gas passage space between a turbinehousing and a catalyst during acceleration, the flow rate is increased so that the spatialresonance region can be quickly passed. When the flow rate (VN passage flow rate) ofexhaust gas passing through the nozzle vanes has reached the spatial resonance regionduring deceleration, the flow rate is decreased so that the spatial resonance region canbe quickly passed. Such a control can reduce a period of time during which the frequencyof pressure pulsation occurring at the rear ends of the nozzle vanes is amplified in thespatial resonance region, whereby noise caused by the pressure pulsation can bereduced.
