Claims

[Scope of utility model registration request]

A butterfly valve is pivotally supported in the exhaust pipe of an internal combustion engine via a rotating shaft located offset from the center of the exhaust pipe, and receives a moment in the opening direction about the rotating shaft due to exhaust gas, and the butterfly valve is integrally mounted on the butterfly valve. For the actuating piece that rotates,
first and second air cylinders that apply a moment in the closing direction opposite to the moment in the opening direction, a first supply path that supplies high-pressure gas to the first air syringe according to the output signal of the low temperature start output signal generator, and an exhaust gas cylinder. and a second supply path for supplying high-pressure gas to a second air cylinder in response to an output signal from the brake switch, and the first air cylinder applies a moment in the closing direction to the butterfly valve that balances the moment in the opening direction. The cold start assist device is configured to be connected to a first set position on the actuating piece, and the second air cylinder is connected to a second set position on the actuating piece so as to apply a closing moment to the butterfly valve that is greater than an opening moment.
