摘要： A method of pressuring fuel for a direct injection fuel system via a fuel pump in an engine is provided. The method includes, during a first mode, adjusting a magnetic solenoid valve (MSV) to control pump outlet pressure and during a second mode, deactivating the MSV and controlling pump outlet pressure via a noise-reducing valve assembly on an inlet side of the fuel pump.

摘要： Systems and methods are provided for a high-pressure fuel pump to mitigate audible ticking noise associated with opening and closing of a digital inlet valve of the high-pressure pump. To reduce the ticking noise associated with the high-pressure pump when the engine is idling, a solution is needed that is simple and does not involve retrofitting the fuel system with noise, vibration, and harshness countermeasures to mask the noise. Pressure devices and associated operation methods are provided that involve adding a combination of several check valves, an accumulator, and a flow control valve with weep channels to allow the digital inlet valve to be deactivated during engine idling as defined by a threshold engine speed.

摘要： A high pressure fuel pump for use with an internal combustion engine and a method of operation of a high pressure fuel pump are disclosed. The high pressure fuel pump may include a supply chamber and a pump chamber separated by a passage in sealing arrangement with a disk. The disk may have one or more holes therethrough and be rotatable in order to place the holes in the disk in varying degrees of alignment with the passage to allow respective, varying amounts of fuel to flow through the passage.

摘要： A direct fuel injection cylinder for an engine of a vehicle includes a direct fuel injector disposed in an injector bore within a cylinder head. A beveled conical wave washer is disposed between a shelf in the injector bore and a shoulder of the direct fuel injector. During operation of the vehicle, the beveled conical wave washer is elastically deformed by radial displacement caused by absorption of high frequency energy from the direct fuel injector. Elastic deformation of the beveled conical wave washer may reduce noise which may be caused by impact of the direct fuel injector and the cylinder head.

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.
