The air inlet of the breather check valve of one bypass of setting, cold on air flue between mouth and the air inlet of exhaust-driven turbo-charger exhaust-gas turbo charger
The gas outlet of the breather check valve of one bypass is set on device to the air flue between the air inlet between inlet manifold；In exhaust gas whirlpool
It is total from throttler valve since the air pressure of the air inlet of breather check valve is higher than gas outlet before taking turns booster generation supercharging effect
At gas outlet outflow air by the air inlet of breather check valve, push valve blade open after, further through gas outlet, Zhi Houzai
Into the air inlet of inlet manifold, therebetween, breather check valve due to ventilation sectional area it is sufficiently large in the case of, the system into
Atmidometer is suitable with the gasoline engine inlet-air resistance of natural aspiration；After exhaust-driven turbo-charger exhaust-gas turbo charger generates supercharging effect, by
It is less than gas outlet in the air pressure of the air inlet of breather check valve, it is unidirectional by air inlet through exhaust-driven turbo-charger exhaust-gas turbo charger air after supercharged
The gas outlet of valve is flowed to air inlet direction, and pushes valve blade to valve seat rotation and closed airway, slave air throttle later
The air of the gas outlet outflow of valve assembly enters inlet manifold by charge air cooler again after being pressurized by exhaust-driven turbo-charger exhaust-gas turbo charger.
The technical solution adopted by the present invention to solve the technical problems is：By throttler valve assembly, exhaust-driven turbo-charger exhaust-gas turbo charger,
Charge air cooler, breather check valve, inlet manifold composition.The air inlet of breather check valve and the gas outlet of throttle valve body assembly and useless
The air inlet connection of air turbine supercharging, the gas outlet of breather check valve and the air inlet of the gas outlet of charge air cooler and inlet manifold connect
It is logical.
It is an advantage of the invention that make exhaust gas turbocharge petrol engine exhaust-driven turbo-charger exhaust-gas turbo charger generate supercharging effect it
Before, the reaction speed suddenly accelerated is suitable with the petrol engine of the natural aspiration of same discharge capacity；It is generated in exhaust-driven turbo-charger exhaust-gas turbo charger
After supercharging effect, the reaction speed accelerated and the exhaust gas turbocharge petrol engine phase for being fitted without breather check valve
When；The range of choice for having bigger in size, the generation supercharging effect initial speed of selection setting exhaust-driven turbo-charger exhaust-gas turbo charger, makes to give up
Influence of the weight difference of air turbine supercharger rotor to exhaust gas turbocharge effect minimizes, the convenient engine with discharge capacity
It selects larger exhaust gas turbocharge to have the supercharging effect of bigger in high engine speed range, while making exhaust-driven turbo-charger exhaust-gas turbo charger again
There is the comparable anxious accelerating ability of the petrol engine of the natural aspiration of same discharge capacity before generating supercharging effect.
