摘要： One embodiment of the invention relates to an electronic fuel injection module including a throttle body including a throat extending between an inlet port and an outlet port and a fuel delivery injector too unit. The fuel delivery injector unit includes a cavity, a fuel inlet, a magnetic assembly, a pumping assembly, a spring, a valve seat, a valve, and an out valve. The fuel inlet receives fuel and directs fuel into the cavity. The magnetic assembly is within the cavity and includes a magnet, a pole, and a hollow sleeve. The pumping assembly includes a bobbin and piston. The bobbin is configured to move the pumping assembly. The piston is coupled to the bobbin. The valve seat is located at one end of the piston. The valve selectively allows fuel to flow into a pressure chamber. The out valve is configured to provide fuel to the throat.

摘要： A marine propulsion system includes an internal combustion engine; a fuel reservoir; a pump that pumps fuel from the fuel reservoir to the internal combustion engine; and a fuel filter that filters the fuel. The fuel filter includes a canister and a fuel inlet that conveys the fuel adjacent to cylindrical sidewalls of the canister so that the fuel immediately spirally flows around and down the cylindrical sidewalls under centrifugal force and under force of gravity, and then is drawn radially inwardly through a filter element by the pump. A fuel outlet extends at least partially along a center axis of the canister and discharges the fuel from the canister. A drain is located at the bottom of the canister and configured to drain water that separates from the fuel as the fuel flows around and down the cylindrical sidewalls.

摘要： A fuel system includes an air residence chamber operative to receive fuel from a fuel tank and allow degassed air to separate from fuel to an upper portion, and a boost pump including a boost pump inlet and a boost pump outlet. The boost pump inlet is in fluid communication with a lower portion of the air residence chamber to pump fluid from the air residence chamber. The system also includes an accumulator in fluid communication with the boost pump outlet. The accumulator includes a reservoir having a reservoir inlet in fluid communication with the boost pump outlet and a reservoir outlet. The accumulator also includes a piston slidably disposed in the reservoir. The piston is operative to push fluid through the reservoir outlet when a pump pressure of the boost pump drops below a predetermined pressure value.

摘要： A carburetor base of an engine defines an axial through hole and a pulsation hole channel. An anti-blocking component is mounted inside the axial through hole and defines an air inlet channel. The air inlet channel communicates with the pulsation hole channel so as to avoid blocking of condensed fuel oil inside the pulsation hole channel.

摘要： A fuel introducing member is connected to an opening end of a siphon pipe forming a fuel tank. The fuel introducing member has an opening for introducing fuel within the tank, and the opening is formed in the upper surface of a cover section. A lid body is pivotably mounted to the upper surface. When the opening is above the level of fuel, the lid body closes the opening by the weight of the lid body, and when the opening is below the level of the fuel, the lid body floats in the fuel to open the opening. The opening is located below the upper end of the inner diameter of the opening end of the siphon pipe.

摘要： A fuel injection system for an internal combustion engine, comprises: a pump comprising a pumping plunger which is driven, in use, to cause pressurization of fuel within a pump chamber, an accumulator volume for supplying fuel to a fuel injector, a fuel passage providing fluid communication between the pump chamber and the accumulator volume, and an inlet control valve operable to control fuel flow into the pump chamber from a low pressure reservoir; wherein the inlet control valve is a latching inlet valve. The fuel injection system may be a hybrid fuel injection system, having a rail valve located in the fuel passage between the pump chamber and the accumulator volume. The latching inlet valve may be a two-way electronic latching poppet valve, and the rail valve may be a non-return valve. A method of operating such a fuel injection system for an internal combustion engine is also described.
