摘要： Disclosed is a solenoid valve assembly for use in an fuel injection pump of a motor vehicle basically comprising an electromagnetic actuator section including a stator, a core and a winding and a valve section having a valve for interrupting flow of fuel in a fuel passage. A rod-like member is coupled between the valve and the core and is movable within a guide hole made at the center of the stator so that the movement of the core is transmitted to the valve. The valve is biased by a spring in a direction closing the fuel passage. The valve is actuated to open the fuel passage in response to energization of the winding and is actuated to close the fuel passage in response to deenergization of the winding, the opening degree of the valve being regulated and adjusted by a stopper. The spring and the stopper is provided at a high pressure side of the fuel passage communicating with a compression chamber of the fuel injection pump.

摘要： In a fuel injection control system for multi-cylinder internal combustion engines, the speed of the engine is monitored and sampled at predetermined angular intervals of engine revolution to detect instantaneous engine speed values identifiable by individual cylinders. From the successively detected instantaneous speeds is derived an average value which is used as a reference for the instantaneous speed values to detect their deviations therefrom. Cylinder-to-cylinder variations in engine speed are minimized by metering the fuel according to the individually derived engine speed deviations.

摘要： A fuel injection pump is described wherein a plunger is rotatingly and reciprocally movable in an enclosure to define a compression chamber which is connected to a fuel inlet during an intake stroke of the plunger and to a fuel outlet during a compression stroke thereby to initiate injection of fuel to the outlet. A solenoid valve is responsive to a voltage applied from a voltage source for providing a pressure relief action on the fuel in the compression chamber. A control unit is responsive to the onset of fuel injection to determine a basic timing at which fuel is to be terminated and corrects the basic timing as a function of the source voltage to compensate for a voltage variation thereof which would otherwise affect on the operation of the solenoid valve. The solenoid valve is then energized at the corrected timing.

摘要： A fuel injection pump of the distribution type is provided with an electromagnetic valve for escaping the fuel in the pump chamber of the fuel injection pump. The fuel injection pump is also provided with a sensor for detecting the rotary angle of a pump shaft. This sensor is attached to a roller ring of a converter mechanism which also comprises a face cam, for example, and which also serves to convert the rotation of the pump shaft the reciprocate with that of a pump plunger. The sensor generates signals which represent the rotary angles of the pump shaft. The operation of the electromagnetic valve is controlled to escape the fuel in the pump chamber, depending upon the signals supplied from the sensor.

摘要： A variable discharge high pressure pump for pumping a fuel into a common rail of a common rail type fuel injection system has a plunger reciprocable in a cylinder bore and a pumping chamber defined between and end face of the plunger and the inner peripheral surface of the cylinder bore. A solenoid valve has a valve member movable into an open position in which the valve member is moved out of engagement with an associated value seat into the pumping chamber when the solenoid valve is deenergized. When the solenoid valve is energized, the valve member is moved into a closed position in which the fuel pressure in the pumping chamber acts on the valve member to urge the same into engagement with the valve seat. The plunger is of a simple cylindrical structure free from any lead formed therein.

摘要： A fuel injection system for a diesel engine has fuel pump driven by the engine for producing highly pressurized fuel, a common rail for storing the pressurized fuel therein and injection nozzles for injecting the pressurized fuel stored in the common rail into the engine. The injection nozzles are electrically controlled in accordance with engine operating conditions (N, .alpha.) by the use of injection control solenoid valves provided between the injection nozzles and the common rail. The fuel pump is electrically controlled in accordance with the engine operating conditions by the use of a spill control solenoid valve which spills the pressurized fuel to a low pressure fuel channel so that loss of engine torque required by the pump is reduced.

摘要： A fuel injection pump according to the present invention is provided with a spill passage and an escape passage which are connected to a pump chamber. Disposed in the middle of the spill passage is a solenoid valve, which is adapted to open the spill passage to spill fuel in the pump chamber to the low-pressure side at predetermined times while the fuel in the pump chamber is pressurized by a pump plunger, thereby adjusting the delivery of compressed fuel from the fuel injection pump. The escape passage is formed in the pump plunger so as to be coaxial therewith. One end of the escape passage communicates with the pump chamber, while the other end opens to the outer peripheral surface of the pump plunger. An escape ring is fitted on the outer peripheral surface of the pump plunger, whereby the opening of the escape passage is opened when the pump plunger reaches a predetermined compression stroke.

摘要： A distributor type fuel-injection pump according to the present invention is provided with a rotor which is rotated by an engine. The rotor has a pair of plungers slidable in the radial direction of the rotor, and a fuel pumping chamber is defined between the plungers. The rotor is surrounded by a cam ring which reciprocates the plungers as the rotor rotates, thereby sucking fuel into the fuel pumping chamber and pressurizing the fuel therein. The fuel pressurized in the fuel pumping chamber is distributed to individual cylinders of the engine. A plurality of spill holes are formed in the rotor, communicating with the fuel pumping chamber and opening to the outer peripheral surface of the rotor. A control sleeve to open and close the spill holes is axially slidably fitted on the rotor. First and second spill grooves capable of communicating with the spill holes are formed on the inner peripheral surface of the control sleeve. The first and second spill grooves open or close the spill holes to define the timing for the start of fuel delivery in the fuel pumping chamber and the timing for the end of fuel delivery, thereby determining the amount of fuel delivery.
