摘要： A device for the electronically controlled lean out of mechanical fuel injected engines comprising a wide band air fuel ratio sensor and a printed circuit board (PCB) connected to the wide band air fuel ratio gauge/controller. The printed circuit board (PCB) is connected to the wide band air fuel ratio sensor's power, ground, and signal wires. The computer controlled stepper motor is connected to the printed circuit board (PCB). A variable valve spool is retained in a fuel block and connected to the computer controlled stepper motor. Rotating the variable valve spool continuously adjusts and controls the air fuel ratio of the engine in real time by regulating the amount of fuel returned the fuel tank and the amount of fuel delivered to the barrel valve in a mechanically fuel injected engine. A jet can be used in combination with the fuel bock to further fine tune the fuel flow.

摘要： A fuel metering valve includes a main flow path extending axially between an inlet and an outlet. Also included is a plunger disposed around a portion of a plunger guide, the plunger and the plunger guide configured to translate between an open position and a closed position to selectively distribute a fuel flowing through the main flow path to the outlet of the fuel metering valve. Further included is a solenoid coil disposed between a solenoid outer body and a solenoid inner body, the solenoid coil configured to magnetically attract the plunger to the open position. Yet further included is a secondary flow path for routing a stagnant volume of fuel upon translation of the plunger from the closed position to the open position.

摘要： A valve assembly in an internal combustion engine fuel system includes a valve member movable within a valve body to contact a valve seat and block fluid communication between first and second passages. The valve seat and valve member each include a multi-layered coating having a harder metal nitride base layer and a softer metal nitride outer layer. The base layer is relatively incompliant to impacts between the valve member and the valve seat, and the outer layer is relatively compliant to the impacts and thereby deformable. Related methodology is disclosed.

摘要： A valve assembly suitable for use as an inlet metering valve of a fuel injection system comprises an inlet opening, an outlet aperture, and a valve element arranged to control fluid flow between the inlet opening and the outlet aperture. The valve element is moveable in response to an applied control signal to a closed position and to a fully-open position, and is biased to return to a rest position when the control signal is absent. When the valve element is in the rest position, fluid flow between the inlet opening and the outlet aperture is permitted at a relatively low rate. When the valve element is in the closed position, fluid flow between the inlet opening and the outlet aperture is substantially prevented. When the valve element is in the fully-open position, fluid flow between the inlet opening and the outlet aperture is permitted at a relatively high rate.

摘要： A fuel injector comprising a hollow body for housing a metering valve with a calibrated pipe for outlet of the fuel from a control chamber. The calibrated pipe is normally kept closed by a shutter controlled by an electromagnet comprising a magnetic core and an electric coil housed in an annular slot of the core. The coil outer cylindrical surface forms a gap with the annular slot so as to be lapped by the fuel coming out of the calibrated pipe. The coil comprises a bobbin having a pair of appendages for supporting electric supply plugs, which are englobed at least in part in a block of non-magnetic material. The bobbin has a substantially cylindrical rib, one flange adjacent to an end portion of the plugs, and another flange having a smaller diameter that forms a passage for the fuel between the calibrated pipe and the gap.
