Pressure is small, and the aperture of flow control valve is adjusted by manual adjustment or program, makes the pressurized air in part (more or less), combustion
Gas mixture is back to the mixed gas inlet end of front end system booster, after re-mixing with air, fuel gas mixture, enters
Booster is pressurized, and the air into gas engine cylinder, the fuel gas mixture scale of construction are reduced, and realizes that control combustion gas is started
The purpose of machine revolving speed and power.
2, by cancelling the air throttle at gas engine cylinder, air, fuel gas mixture enter gas engine cylinder
Without restriction loss, the charging efficiency of booster is improved, meanwhile, air, combustion gas mixing into booster mixed gas inlet end
Object pressure is larger, and the booster of the directly smaller boost horsepower of matching can meet pressurization and require, and reduces the purchase cost of booster,
Further decrease the use cost of gas engine.
3, the powered controls of gas engine of the present invention, air, fuel gas mixture into gas engine cylinder
Variable quantity (variable quantity is only to pass through the regurgitant volume of flow control valve) smaller, gas engine revolving speed and power swing range
It is small, moreover it is possible to effectively to avoid booster that surge occurs, guarantee that booster is normal, is safely operated.
4, inventive flow regulating valve is stepper motor driven control valve, can be accurately adjusted opening for flow control valve
Degree realizes the purpose of accurate control gas engine revolving speed, power.
5, air throttle is arranged in the present invention at gas engine cylinder, in case of emergency closes and realizes that stopping is sent out to combustion gas
Motivation cylinder provides air, fuel gas mixture, meets associated safety demand.
It is further described with reference to the accompanying drawings and detailed description.
Detailed description of the invention
Fig. 1 is the principle of the present invention schematic diagram；
Fig. 2 is connection schematic diagram of the invention；
Fig. 3 is the connection schematic diagram of inventive flow regulating valve.
In attached drawing, 1 is booster, and 2 be intercooler, and 3 be the first gas circuit, and 4 be the second gas circuit, and 5 be flow control valve, and 6 are
