摘要： Disclosed are a fuel supply system and method for a ship engine. The fuel supply system for a ship engine of the present invention comprises: a first flow channel which is connected to an LNG storage tank of a ship, pumps and vaporizes liquid natural gas stored in the LNG storage tank, and supplies the same to a first engine provided to the ship; a pressure reducing flow channel which branches out from the first flow channel, reduces the pressure of the pumped and vaporized natural gas, and supplies the same to a second engine provided to the ship; and a pressure maintaining flow channel which branches out from the pressure reducing flow channel and supplies the pressure reduced natural gas to the LNG storage tank.

摘要： A vehicle natural gas fuel supply system includes a vehicle-tank natural gas fuel supply assembly and a vehicle natural gas fuel supply assembly, and at least one quick-connect-coupler for removably coupling the vehicle-tank natural gas fuel supply assembly and the vehicle natural gas fuel supply assembly. The vehicle-tank includes a natural gas tanker-trailer and the vehicle-tank is a pressurized vessel. A vehicle natural gas fuel supply system may eliminate a need to vent captured natural gas from the vehicle-tank. The captured natural gas, by remaining in a closed system and not being vented, effectively prevents unburned methane from entering into an ambient environment. The captured natural gas is directed through an air-gas mixer before reaching the engine of the prime-mover for motive action.

摘要： An object is to improve a trap effect to trap ignition fuel gas supplied to a pre-combustion chamber and reduce an amount of non-combusted ignition fuel gas flowing out of the pre-combustion chamber to suppress a decrease in combustion efficiency. A pre-combustion-chamber type gas engine includes: a pre-combustion chamber Sr disposed on a cylinder head portion 10; a spark plug 20 disposed on an upper part of the pre-combustion chamber Sr; a pre-combustion-chamber gas supply mechanism configured to supply ignition fuel gas “g” to the pre-combustion chamber Sr via gas supply channels for the pre-combustion chamber 22a and 22b with an opening on an upper part of the pre-combustion chamber Sr; and a check valve 24 disposed in the gas supply channel 22b for the pre-combustion chamber. The opening of the gas supply channel 22a for the pre-combustion chamber is disposed on a lower surface of a cover member 16 forming the pre-combustion chamber Sr or on an upper section of a side wall of a pre-combustion-chamber member 14, the opening facing in a tangent direction of a side-wall inner peripheral surface 14a of the pre-combustion-chamber member 14. The ignition fuel gas “g” supplied to the pre-combustion chamber Sr forms a swirl flow s1 which swirls about a longitudinal axis x of the pre-combustion chamber Sr inside the pre-combustion chamber Sr.

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