Claims

[Scope of Claim for Utility Model Registration] In an internal combustion engine with a turbocharger, a bypass passage that bypasses the compressor of the turbocharger, a bypass valve that opens and closes the bypass passage with respect to the intake pipe of the engine, and a switch between the open and closed positions of the bypass valve. means for biasing the bypass valve to the closed position during normal operation of the engine; means for driving the actuator so that the bypass valve remains open for a desired period of time during sudden acceleration or deceleration of the engine; A device for improving acceleration/deceleration response of a turbocharged internal combustion engine, comprising means for improving acceleration/deceleration response of a turbocharged internal combustion engine.
