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 prevent malfunctioning of an apparatus for controlling the fuel injection timing, by providing an ignition judging means for judging whether fuel is ignited normally or not in feedback controlling the fuel injection timing of a diesel engine by detecting the actual ignition timing. CONSTITUTION:The actual ignition timing is detected from the output signals of a reference position detector 4 and an ignition timing detector 5, and an aimed ignition timing is detected from the output signal of an engine speed detector 6D. The fuel injection timing is corrected according to the deviation between the aimed ignition timing and the actual ignition timing. Further, whether ignition of fuel is normal or not is judged from the output signals of an injection quantity detector 6A, engine speed detector 6D and ignition timing detector 5. If ignition is not normal, feedback control is stopped. With such an arrangement, it is enabled to prevent malfunctioning of the apparatus even if no ignition signal is obtained, for instance, when trouble is caused with the ignition timing detector or fuel supply is interrupted.
