摘要： PURPOSE: To feed predetermined amount of fuel at anytime by detecting the operation of fuel injection pump through the phase angle of driven shaft then time converting only such range as the detection of angle is substantially unable and injecting predetermined amount of fuel.
CONSTITUTION: On the basis of the load information from unit angle sensor 50, accelerator sensor 40 and temperature sensor 45, a control circuit 26 will determine the fuel injection to obtain the spill start timing of time unit from two-dimensional map of engine rotation thus to turn on a spill solenoid valve 21 upon elapse of Tθ from the referential angle signal detecting time point of referential angle sensor 30 and to finish injection. If there is variation of rotation, it will cause a spill timing error thereby the count of unit angle signal from the sensor 50 and the time count through a time counter are employed to execute control having low spill timing error. Consequently, specific amount of fuel is ensured irrespectively of the varying time point of engine rotation resulting in improvement of fuel consumption.

摘要： PURPOSE:To readily control fuel injection amount accurately with good stop of injection by providing an overflowing port at a fuel distribution rotary member capable of merely rotating and providing a groove in the bore side of a ring- shaped member which is externally engaged with the rotary member. CONSTITUTION:When a fuel distribution rotary member 4 is rotated at 1/2 of revolution (in case of four cylinders) to the rotation of an engine, pressure feed plungers 21, 22 reciprocate in accordance with the profile of an inner cam 1, thereby pressurizing the fuel in a pump chamber 2. This pressurized fuel is distributed through a guide hole 3 to a distribution port 6, and supplied from fuel supply passages 61-64 to the respective cylindrical bores into the respective fuel injection valves. In this case, overflowing ports 71-74 are formed to communicate with the hole 3 in the member 4, and a ring-shaped member 7 is engaged axially slidably with the port forming position. A lead groove 10 is formed in the bore side of the member 7, and when the ports 71-74 coincide with the groove 10, the pressurized fuel is overflowed, thereby stopping the injection of the fuel.

摘要： PURPOSE:To simplify the processing of injection quantity control, by storing the period from a reference time to the time when an overflow solenoid valve is opened by dividing the period into a pre-stroke period when fuel is not injected substantially and a period when fuel is injected actually. CONSTITUTION:Processing of interruption is started when a signal is furnished from a pump bottom dead point sensor 13 to an ECU9 during operation of an engine. That is, a solenoid valve 8 is at first de-energized to stop overflow of high-pressure fuel in a pump chamber 5, and then a time thetae corresponding to the injection quantity of fuel is searched from a prepared map on the basis of the output signals of an engine-speed sensor 10, a sensor 11 for detecting the position of an accelerator pedal, an idle-position sensor 12, sensors 14, 15 for detecting the ambient pressure and temperature of the engine, etc., and the time thetae is corrected appropriately according to the temperature, pressure, etc. Then, by reading a pre-stroke period thetaR and adding thetaethetaR to it, the total time (crank angle) is detected and the solenoid valve 8 is energized when the period from the time when the solenoid valve 8 is de-energized becomes equal to said total time.
