置。An on-off valve that can open and close the exhaust passage of the engine, a working gas receiving chamber that is supplied with working gas from a pressure supply source, and a movable member that fluctuates in response to the operating force of the on-off valve from the working gas in this working gas receiving chamber. A means for regulating the flow of the working gas is installed in the path through which the working gas in the working gas receiving chamber is released to the atmosphere, and this means for regulating the flow of the working gas controls the opening operation of the on-off valve. A cold start assist device configured to slow down the speed.
