PURPOSE:To feed such oil as being commensurate to engine load, by generating a motor driving signal with a proper oil fed signal commensurate to the engine load on the basis of a differential signal between a detected accelerator opening signal and an engine speed signal. CONSTITUTION:Opening of an accelerator 1 is detected with a potentiometer 2, while an accelerator opening signal in proportion to the opening is outputted and connected to a noninverted input terminal of a differential amplifer 4. In addition, an ignition pulse taken out of an ignition coil 5 is made into an F/V conversion, through which such an engine speed signal as being equivalent to the number of revolutions in an engine is generated. Output of a buffer amplifier 10 is connected to an inverted input terminal of the differential amplifier 4. On the other hand, this differential amplifier 4 generate a proper oil feed signal commensurate to engine load on the basis of a differential signal between an accelerator opening signal and an engine speed signal, while a comparator 13 is outputted to a driving circuit 14 of a motor 15 from an engine load signal and a saw-tooth type wave signal out of an integration circuit 12. |
