摘要： A fuel injector assembly includes a first coil that induces a time varying magnetic field into a second coil that is utilized to heat fuel flowing through the fuel injector. The second coil generates a second magnetic field generated by a current induced by the first coil into the second coil. The induced current is generated by an alternating current signal that is interposed onto a direct current signal sent to the first coil. The second coil also is electrically connected to pass current induced from the first coil into a component in thermal contact with the flowing fuel. The current from the secondary coil resistibly heats the component to provide an alternate mode of heating fuel flow.

The metering orifice disc has an outer diameter from 4 to 6 millimeters with at least one orifice disposed through the metering disc of about 75 to 150 microns in effective diameter.

摘要： A gasoline unit injector includes a high speed, high force actuator such as a magnetrostrictive or piezoelectric actuator. The actuator operates a positive displacement diaphragm pump. The pumping volume is isolated from a supply rail by an inlet check valve, and is isolated from the engine manifold by an outlet check valve. Each of the check valves includes a disk having a central anchor and a peripheral valve seat. Diaphragm movement reduces pump volume and thereby displaces fuel at high pressure through outlet valve. Fuel spray is formed by geometry of outlet valve, the frequency of actuation, and mass and pressure of the displaced fuel. Relaxation of actuator, and therefore diaphragm, increases pump volume and thereby draws fuel into pump volume through the check valve.

摘要： A fuel rail that forms a conduit for pressurized fuel to be delivered to at least one fuel injector. The fuel rail includes an elongated member that is corrugated such that the fuel rail acts as a pressure damper. A method of reducing pressure pulsation in a fuel system is achieved by configuring a fuel of a second configuration from an initial configuration, the second configuration having a first portion and a second portion, the first portion having at least three points defining a virtual plane, the first portion including a continuous surface that intersects the virtual plane at a plurality of positions.
