PURPOSE: To automatically follow a load fluctuation in a gas engine so as to prevent excess rotation and so as to improve load responsiveness by providing a device, which increases a pressure of auxiliary fuel gas, a device, which separately recovers a lubricating oil, a device, which automatically supplies the lubricating oil, and a valve unit for the auxiliary fuel gas.
CONSTITUTION: Fuel gas is fed from a main fuel gas equipment unit 1 to a gas control valve 2 to be mixed with air, and then a fuel-air mixture is compressed by a turbocharger 3. The fuel-air mixture is cooled down by an aftercooler 4, fed to an intake manifold 5, and inhaled by a cylinder 6. In an auxiliary combustion gas compressor unit, the fuel gas is compressed by a compressor 11 to be fed to an aftercooler 8. In this process, the compressor 11 opens/closes an electromagnetic valve 13 by its oil level switch 12. On the other hand, an oil separator unit 9 feeds the oil among the fuel gas, which is cooled down by the aftercooler 8, to the compressor 11, and refluxes the fuel gas to an auxiliary gas valve unit 10.
