The use of smaller turbines, combined with exhaust gas bypass at high speeds, is a key technology to address this problem. In the starting stage of the vehicle, the energy of the waste gas of the engine is limited, and a smaller turbine can be driven to work efficiently more easily; and in the high-power stage of the engine, the excessive waste gas is directly discharged by adopting the bypass of the air release valve mechanism without passing through the turbine, so that the overspeed problem of the engine is effectively solved while the supercharging capacity is met.
