摘要： A fuel delivery system includes a fuel pump assembly, an extension tube, and an injection nozzle assembly. The fuel pump assembly includes a pumping chamber, an inlet valve configured to direct fuel to the pumping chamber, a piston configured to pressurize fuel in the pumping chamber, an electromagnetic actuator operatively coupled to the piston, and an outlet check valve configured to direct pressurized fuel out of the pumping chamber. The electromagnetic actuator is configured to produce a force sufficient to move the piston to pressurize fuel in the pumping chamber and direct pressurized fuel through the outlet check valve. The extension tube is located downstream of the outlet check valve, and the injection nozzle assembly is located downstream of the extension tube. The injection nozzle assembly includes a nozzle check valve configured to selectively permit pressurized fuel received from the outlet check valve through the extension tube to exit the fuel delivery system.

摘要： A vehicle and a method of reducing sound produced by a liquid fluid pump are disclosed. A pump is activated when a predetermined event is detected. A control valve of the pump is operated in one of an initial and a standard mode when the pump is activated. The control valve is operable to allow a gaseous fluid to vent out of the pump when in the initial mode corresponding to the pump being in a first phase. The control valve is operable to allow a liquid fluid to move through the pump when in the standard mode corresponding to the pump being in a second phase. A solenoid of the control valve is energized and de-energized, at a calibrated frequency, in a sequence when in the initial mode to reduce the sound in the pump during the initial mode.

摘要： A fuel system is provided for supplying pressurized fuel, in particular dimethyl ether (DME) or a blend thereof, to an internal combustion engine. The fuel system includes a fuel pump, which has a pumping mechanism arranged partly in a housing containing lube oil, a drain line connected to the housing and suitable for draining at least fuel vapor from an interior of the housing, a lube oil supply line connected to the housing, a lube oil supply valve installed in the lube oil supply line, a seal installed between the pumping mechanism and the housing for preventing at least lube oil leakage to the outside of the housing, and a drain valve installed in the drain line, wherein both the drain valve and lube oil supply valve are controlled to be closed during an engine non-running state for preventing fuel vapor leakage from the housing.

摘要： The mechanical lifter generally includes an inner lift member, an outer lift member, and a roller. The inner lift member is at least partly made of a metallic material. The outer lift member is at least partly made of a polymeric material and surrounds the inner lift member. The roller is rotatably coupled with respect to the inner lift member and is partly disposed within the inner lift member. The inner lift member is configured to move a first component in response to a force applied to the roller by a second component.

摘要： A method for operating a fuel pump is provided. The method may include decreasing a pump chamber pressure, passively opening a metering valve coupled to a pump chamber in response to the decreasing, and while the metering valve is open, generating a rotational output via a motor, transferring the rotational output into an actuation force applied to the metering valve via a metering valve actuation device, and inhibiting the metering valve from closing via sustaining application of the actuation force.

摘要： A carburetor improves the starting performance of an engine. The carburetor includes a main body, a pump oil ball and a fuel-air mixing channel which extends through the main body. The pump oil ball is mounted to an air strangler spindle via a spiral groove. When the pump oil ball is pressed, the air strangler spindle is driven to rotate by the spiral groove and thus to control the air strangler spindle between the fully open state and the fully closed state. The carburetor dramatically improves the starting performance of the engine.

摘要： An automobile fuel system pressurization apparatus includes an inflatable bladder having a proximal end, a distal end, an exterior surface, and an inlet accessing an interior. The inflatable bladder being deformable between an expanded state and a deflated state. In the expanded state, the exterior surface of the inflatable bladder is configured to provide an air-tight seal in a filler neck of a fuel tank. A pump is coupled to the inlet of the inflatable bladder and is configured to supply air pressure to the interior of the inflatable bladder. A pressure relief valve is disposed at the distal end of the inflatable bladder and is in fluid communication with the interior of the inflatable bladder. When the inflatable bladder is in the expanded state, the pressure relief valve is configured to release a portion of the air pressure from the interior of the inflatable bladder into the fuel tank.
