Definitions

  • the present invention relates to a fuel supply device that supplies gas fuel to an engine that uses gas fuel.
  • the present disclosure relates to a fuel supply device that supplies gas fuel as fuel to an engine.
  • the fuel supply device connects the fuel container for accumulating and storing the gaseous fuel, the fuel injection valve for injecting the gaseous fuel so as to be burned by the engine, the fuel container and the fuel injection valve, and connecting the gas A fuel passage through which the fuel flows; and an addition unit that adds a lubricant that improves the slidability inside the fuel injection valve to the gas fuel that flows through the fuel passage.
  • the exhaust pipe 14 is provided with exhaust sensors 18a and 18b for detecting components in the exhaust.
  • the exhaust sensors 18a and 18b are oxygen sensors that output a detection signal corresponding to the oxygen concentration in the exhaust.
  • a main stop valve 44 and a shut-off valve 45 disposed downstream of the main stop valve 44 are provided between the fuel container 42 and the pressure reducing valve 43. These valves 44 and 45 allow and block the flow of gas fuel in the fuel passage 41.
  • the main stop valve 44 and the shut-off valve 45 are electromagnetic on-off valves, and are a normally closed type in which the flow of gas fuel is blocked when not energized and the gas fuel is allowed to flow when energized.
  • step S11 the fuel temperature Tf of the gas fuel in the fuel passage 41 is acquired. Specifically, the detection value of the temperature sensor 48 is acquired as the fuel temperature Tf.
  • the fuel supply device 40 can reduce the frictional resistance on the friction surface in the injector 21 by including the addition unit 50. Therefore, the fuel supply device 40 can use an injector for liquid fuel as the injector 21, and can reduce the cost compared to the case where an injector for gaseous fuel is used.
  • a lubricant for improving the slidability inside the injector 21 water may be used instead of the lubricating oil.
