摘要： A distribution type fuel injection pump includes a control cylindrical bore into which a control plunger is fitted. The control plunger partitions the control cylindrical bore into first and second chambers. The same pressure as that of fuel in the pumping chamber (which serves to feed fuel) is transmitted to the first chamber, while fuel is supplied to the second chamber through a control passage. An electromagnetic valve is arranged in the control passage and the amount of fuel with which the second chamber is filled is adjusted by controlling the electromagnetic valve.

摘要： The engine speed is periodically detected at every predetermined crankshaft angles for obtaining a plurality of engine speed data whose number equals an integral multiple of the number of cylinders of an internal combustion engine. Either maximum or minimum values among the plurality of engine speed data is determined, and such operations are repeated for a duration covering all power strokes within all the cylinders, thereby obtaining a plurality of sets of engine speed data. Then the order of engine speed data giving the maximum or minimum value within each set is obtained, and majority decision is effected to determine which order of data gives the maximum or minimum most frequently throughout all the sets. The difference between the maximum and minimum values is obtained for each set, and the amount of fuel to be supplied to the engine is controlled so that the difference becomes common to all the cylinders. The fuel amount control may be effected by means of an actuator which controls the position of a spill ring of a distributor injection pump.

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.

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： In a fuel injection pump, an engine drives a rotary plunger having an axially extending bore connected to a compression chamber, plural fuel inlet ports alignable with an inlet passage for introducing fuel to the compression chamber, fuel distribution ports for distributing the compressed fuel through the bore to each one of the fuel delivery passages and plural spill ports. A spill-port timing control unit is provided comprising a stator core, a coil wound on thereon, a magnetized ring having a spill groove, and a spring for resiliently maintaining the ring in a reference angular position with respect to the stator core. The magnetized ring is mounted on the plunger so that it can rotate from the reference angular position to an angularly displaced position in proportion to the magnetic flux of the coil to align the spill groove of the ring with each spill port of the plunger to create a passageway through which the compressed fuel is allowed to escape at the termination of fuel injection.

摘要： Fuel injection pump of the type arranged to inject fuel into engine cylinders with the fuel flow being controlled by an electromagnetic valve, comprises a rotor arranged to rotate in timed relation to engine rotation, and a shuttle movably received in an axial bore made in the rotor. Opposite sides of the shuttle define first and second chambers within the axial bore, where the first chamber is used as a compression chamber to pressurize fuel introduced therein via the electromagnetic valve to inject the same into engine cylinders, and the second chamber is communicable with a low pressure fuel reservoir. Fuel is fed into the first and second chambers during an intake stroke or mode, and then the second chamber fuel is pressurized by means of an inner cam mechanism so that the shuttle moves toward the first chamber to pressurize the fuel therein, thereby injecting the fuel during a compression stroke. When the shuttle has been moved toward the first chamber beyond a predetermined position, the second chamber communicates with the low pressure fuel reservoir via a by-pass, lowering fuel pressure in the second chamber to terminate injection. The amount of fuel injected into cylinders is controlled by the stroke of the shuttle toward the first chamber, which stroke is initially determined by the energizing interval of the electromagnetic valve.

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： An apparatus for measuring a flow of intake air to an engine includes a bridge circuit including a heat resistor placed in an intake air path of the engine, a resistor for sensing the temperature of the intake air, and a plurality of balance resistors. A heating current is supplied to this bridge circuit through a transistor controlled by a periodical current-passage control signal generated by a microcomputer. A signal Vh, representing a temperature change of the heat resistor heated by the heating current, is detected by the microcomputer. A first correction value is computed by using a difference between the detected value from the microcomputer and a signal Vho, representing temperature of the heat resistor when the bridge circuit is balanced at normal temperature. A time width correction value .DELTA.Do1 is computed from a table on the basis of the first correction value. The correction signal .DELTA.Do1 is used for correcting the current passage time. The current passage time width as corrected is used for computing a flow of the intake air.

摘要： A distributor type fuel injection pump of the present invention is of the Lucas type having a rotor rotatably driven by an engine but not reciprocated. Spill ports of the same number as that of the cylinders of the engine communicating with a pump chamber are opened at an equal peripheral interval on the outer peripheral surface of the rotor, and a spill ring to cover the spill ports is slidably mounted on the outer peripheral surface of the rotor. A spill groove is formed to extend axially on the inner peripheral surface of this spill ring. One edge of the spill groove, which initially meets the respective spill ports during the pressurizing step for pressurizing the fuel in the pump chamber, is inclined to the axis, and the other edge of the spill groove is parallel to the axis.
