FUEL GAS SUPPLY SYSTEM OF GAS ENGINE

The present invention provides a fuel gas supply system of a gas engine, the fuel gas supply system being capable of supplying to a fuel gas supply unit a fuel gas of constant pressure which fluctuates little. In a fuel gas supply system 1, a high-pressure tank 3 and a gas injector 5 are connected t...

Beschreibung
Zusammenfassung:	The present invention provides a fuel gas supply system of a gas engine, the fuel gas supply system being capable of supplying to a fuel gas supply unit a fuel gas of constant pressure which fluctuates little. In a fuel gas supply system 1, a high-pressure tank 3 and a gas injector 5 are connected to each other by a supply passage 4, and an electromagnetic pressure regulating valve 6 is provided on the supply passage 4. The electromagnetic pressure regulating valve 6 is configured to regulate the pressure of the gas, flowing through the supply passage 4, to pressure corresponding to a current supplied to the electromagnetic pressure regulating valve 6. The gas pressure downstream of the electromagnetic pressure regulating valve 6 is detected by a low-pressure-side pressure sensor 9. A controller 10 is electrically connected to the electromagnetic pressure regulating valve 6. The controller 10 controls the current supplied to the electromagnetic pressure regulating valve 6 such that pressure detected by the low-pressure-side pressure sensor 9 becomes predetermined target pressure.
