摘要： A fuel delivery system for an internal combustion engine that includes a fuel supply with a fuel pump responsive to application of electrical power for supplying fuel under pressure to fuel injectors mounted on the engine. A pressure sensor is coupled to the pump/injector fuel delivery line for measuring fuel delivery pressure. A second sensor is positioned within the fuel tank and is responsive to fuel alcohol concentration. The pump motor is energized by a pulsed d.c. signal having a duty cycle that varies as a combined function of the pressure and alcohol-concentration sensor output signals so as to maintain constant fuel pressure at the injectors while automatically compensating quantity of fuel delivered by the injectors for differing fuel alcohol concentrations.

摘要： A self-contained brushless electric-motor fuel pump for internal combustion engine fuel delivery systems and like applications in accordance with the present invention comprises a housing having a fuel inlet and fuel outlet, and a brushless electric motor with a permanent magnet armature mounted for rotation within the housing and stator windings surrounding the armature within the housing. A pump mechanism is positioned between the fuel inlet and outlet, and is coupled to the armature for corotation with the armature within the housing to pump fuel under pressure from the inlet to the outlet. A pressure sensor is operatively coupled to the fuel outlet within the housing for providing an electrical pressure signal as a function of fuel pressure at the outlet. Pump motor control electronics within the housing includes circuitry for comparing the pressure signal from the pressure sensor to a pump drive reference signal, and providing an error signal as a function of a difference therebetween. Drive current is applied to the stator windings of the motor as a function of such error signal.

摘要： A two-stroke internal combustion engine having at least one cylinder with a combustion chamber defined between the cylinder head and a reciprocating piston, and a carburetor which delivers a rich fuel and air mixture to a compressor with a reciprocating piston driven by the engine to compress the mixture until the mixture is under sufficient pressure to open a differential pressure injection valve and thereby inject the mixture directly into the engine combustion chamber. The mixture is ignited by a spark plug to drive the engine piston through its power stroke and rotate its associated crankshaft which is connected to a crankshaft of the compressor to reciprocate its piston and thereby compress the fuel and air mixture and inject it into the cylinder in timed relation with the engine piston.

摘要： An electric-motor fuel pump that includes a housing with a fuel inlet and a fuel outlet, and an electric motor with a rotor responsive to application of electrical power for rotating within the housing. A pump mechanism includes an impeller coupled to the rotor for corotation with the rotor and having a periphery with a circumferential array of impeller vanes. A pair of plates oppose the sides of the impeller and a split ring surrounds the periphery of the impeller to form an arcuate pumping channel around the periphery of the impeller. Inlet and outlet ports at opposed ends of the pumping channel are operatively coupled to the inlet and outlet in the pump housing. Channels extend radially inwardly from the pockets in each side face of the impeller, and are interconnected by through-passages that extend through the impeller. A vapor vent is disposed in one of the side plates for sequential registry with the impeller through-openings for venting vapor from the pumping channel.

摘要： In a fuel system for an internal combustion engine powering a motor vehicle, a fuel reservoir canister mounted in a main fuel tank. An annular fuel filter element is enclosed in an axially elongate housing with radially spaced apart inner and outer cylindrical side walls. The housing is received in the canister with its outer side wall bearing on and radially supported by a complementary side wall of the canister. Preferably, a fuel pump and pressure regulator are disposed in the canister preferably so they overlap with and are encircled by the filter housing. The high pressure outlet of the fuel pump is connected to the filter to supply filtered fuel to the engine at a pressure regulated and controlled by the pressure regulator.

摘要： A fuel pressure regulator for a no-return fuel system for an automotive engine with fuel injectors having a housing with a flexible diaphragm between first and second chambers. The second chamber has a fuel inlet with a valve therein to admit fuel to the second chamber and an outlet to supply fuel to the engine. The second chamber is in continuous communication with the engine to accumulate any fuel expansion that may occur during engine deceleration or when the engine is turned off due to heating the fuel. The first chamber continuously communicates with the engine air intake manifold so that fuel is supplied to the engine fuel injectors at a substantially constant pressure drop across the injectors.

摘要： A main fuel tank in an automotive vehicle contains a reservoir in which is located a two-stage electrically operated pump. The first stage is a jet pump which draws fuel from the main tank and delivers it to the reservoir. The second stage is a rotary pump which draws from the reservoir and delivers to the vehicle engine. The reservoir has overflow restriction means which allows air to vent while the reservoir is filling but which restricts fuel flow when the reservoir is full. This creates pressure in the reservoir to create back pressure against and shut down flow from the jet pump and also increase pressure on the fuel inlet of the main pump thus increasing the efficiency of the main fuel pump.

摘要： A fuel pressure regulator with a flexible diaphragm defining in part first and second chambers in a housing and moving a ball valve in the first chamber to open and closed positions to regulate pressure of fuel discharged from the first chamber through an outlet having a seat on which the ball is received when the valve is closed. A cage carried by the diaphragm cooperates with a carrier member or disc fixed to the ball to provide a lost motion coupling between the diaphragm and the ball valve. This coupling permits movement within predetermined limits of the diaphragm generally axially, radially and pivotally relative to the ball while it remains on its seat and upon further generally axial movement of the diaphragm open and partially closes the ball valve to regulate and maintain substantially constant the pressure of fuel discharged from the chamber over substantially the full range of the rate at which the fuel is discharged. Preferably, to further improve regulation, a restricted orifice is disposed in the outlet downstream of the valve seat.
