Structure.
Background technology
To obtain bigger torque output, the mode of exhaust-driven turbo-charger exhaust-gas turbo charger of gasoline engine often taking improve admission pressure with
Increase air inflow.But because the operating condition of gasoline engine is transition, engine speed can directly change to highest from idling
Rotating speed, can also be from Smaller load mutation to big load, therefore fixed volute and the exhaust-driven turbo-charger exhaust-gas turbo charger of turbine size can not
All keep efficient in all condition ranges that gasoline engine is run, exhaust-driven turbo-charger exhaust-gas turbo charger matches the big load of high rotating speed and can caused
Moment of torsion is not enough during the slow-speed of revolution, and supercharging and larger exhaust can be produced in the big load of high rotating speed by matching slow-speed of revolution Smaller load
Resistance.For reply above mentioned problem, more universal solution is that exhaust-driven turbo-charger exhaust-gas turbo charger is matched into the slow-speed of revolution now, it is ensured that
The low speed torque output of gasoline engine, and the form deflated during load big to high rotating speed using by-passing valve is by excessive exhaust gas bypass
Fall, reduce the boost pressure of compressor.Exhaust-driven turbo-charger exhaust-gas turbo charger using it is more be capsule type exhaust gas by-pass valve deflation structure,
Bellows upper chamber directly communicates with blower outlet, when boost pressure exceedes the pressure limit of setting, in bellows upper chamber
Pressure can extrude diaphragm and overcome outside atmospheric pressure and spring force to promote push rod that exhaust gas by-pass valve is opened into realization deflation.
Exhaust-driven turbo-charger exhaust-gas turbo charger also increases the exhaust resistance of engine while admission pressure is lifted, also just because of its
The power output of engine is increased, this partial loss also tends to be ignored.The load control manner adjusted for gasoline engine amount
For, the non-standard-sized sheet of sub-load air throttle, pressure is often below local atmospheric pressure after air throttle, that is to say, that engine is not required to
Want plenum also to meet the air inflow demand of partial load condition, now continue to keep exhaust-driven turbo-charger exhaust-gas turbo charger pressurized state
The exhaust resistance of engine can be increased on the contrary, the economy of part load engine is reduced.In consideration of it, the present invention proposes one kind
Double capsule type gasoline exhaust turbine bypass valve control methods and structure, while Pressurized deflating was ensured, moreover it is possible to realize
Admission pressure, which is less than, equally opens exhaust gas by-pass valve when local atmospheric pressure does not need super charge, increase waste gas circulation interface, drop
Low exhaust resistance loss, improves the fuel economy of gasoline engine sub-load.
