Abstract: A fuel pressure regulator controls the pressure differential across a nozzle which is subject to variations in exhaust gas backpressure having a solenoid actuated valve member which is actuable in response to signals from a controller to establish a predetermined fuel pressure across the nozzle consistent with a control strategy. A pressure dependent valve actuator is operable on the valve member, independently of the solenoid, to adjust the valve opening and, as such, the fuel pressure at the nozzle to adjust the fuel pressure in response to exhaust gas.

Abstract: In a fuel injection system for a multi-cylinder internal combustion engine, a plurality of injection nozzles discharge fuel adjacent the engine inlet ports, and a single injector meters the fuel to all of the injection nozzles. The injector may include an annular valve surface, a plurality of discharge passages opening through the valve surface to direct fuel to the nozzles, and a single valve member associated with the valve surface to control fuel delivery to the discharge passages. The injector may include a rectifier valve that admits air to the discharge passages when the valve member precludes fuel delivery to the discharge passages. The fuel discharge lines that connect the injector discharge passages to the nozzles may be surrounded by air lines.

Abstract: A remote control lever module comprising a support including a bearing and a lever including a shaft pivotably supported by the bearing for oscillation about the shaft axis between a nonactuating position and actuating positions. The lever further includes an actuating arm extending from the shaft at an angle thereto for moving the shaft between the nonactuating position and the actuating positions and a return spring acting on the lever when the shaft is in the actuating positions to urge the shaft to the nonactuating position. Magnets are fixed on the shaft and movable therewith to provide a movable magnetic field of varying strength in an effective zone adjacent one side of the shaft. A magnetic field sensor is fixed to the support adjacent to the shaft in the effective zone of the magnetic field and operative to sense the variation in strength of the magnetic field at various positions of the shaft and to form a readable output signal proportional to the variations for indicating the angular position of the shaft. The lever module may also have a lever force switch engageable by the shaft to close the switch when the actuating arm urges the shaft into the actuating positions.

Abstract: A system and method of limiting the wheel slip of a driven wheel of a vehicle to a maximum allowable value so as to maximize the driven wheel tractive force is described. The driven wheel tractive force represented by an expression including the engine intake air flow area, a load variable function and the speed of an undriven wheel is continually monitored. The value of the monitored tractive force at the time the driven wheel slip reaches a maximum allowable value is identified and stored. When the slip exceeds the maximum allowable value, an intake air flow area is limited to a value determined to return the driven wheel tractive force to the identified tractive force at the maximum allowable wheel slip value.

Abstract: A pressure regulator assembly, suitable for controlling the flow of compressed natural gas to fuel an internal combustion engine, has a small primary valve positioned by a regulator diaphragm to control the flow at high supply pressures and a large secondary valve to provide additional flow area at low supply pressures. Flow to the primary valve passes through a chamber having a restricted aperture from the inlet, and a control diaphragm responsive to the pressure in the chamber opens the secondary valve when the primary valve reaches its maximum flow capacity and the pressure in the chamber approaches the regulated pressure.

Abstract: Induction air flow to an internal combustion engine is controlled or measured by a butterfly valve which extends into undercut recesses on opposite sides of the valve bore. The valve member rotates in excess of 90.degree. between its minimum air flow position and its maximum air flow position and offers a relatively low normalized change in the flow area around the valve.

Abstract: An engine charge forming device controls the fuel metering orifice area in proportion to the throttled air flow area of the induction passage and controls the pressure drop across the fuel metering orifice in proportion to a vacuum signal which is substantially independent of the compressibility effects of throttled air flow; fuel flow is thereby proportioned to air flow throughout the range of engine operating conditions. Adjustments are provided for varying the fuel metering orifice area to set minimum and maximum fuel flows, and controls are provided for modifying the vacuum signal to vary air-fuel ratio.

Abstract: A command signal drives a carburetor metering valve to provide the carburetor fuel flow which will establish a desired air-fuel ratio; simultaneously, the command signal drives a control unit which purges fuel vapor from a fuel vapor storage region. The control unit minimizes purge flow when either maximum fuel flow or minimum fuel flow is commanded and maximizes purge flow when an intermediate fuel flow is commanded; accordingly, fuel vapor is purged from the vapor storage region only when the purge flow cannot unduly enrich or unduly lean the mixture.
