PURPOSE:To obtain the maximum capacity of an engine constantly in the whole state of operation by selecting the optimum values of ignition timing and opening/closing angle of a valve memorized corresponding to the revolution number and the load of the engine in accordance with the loaded state of the engine automatically detected. CONSTITUTION:A spool valve to change the operation angle of a fuel injection pump 30 in accordance with the operation of a control motor 14 is provided within a car shaft gear 8 in gear lines 7, 8, 27, and 28 to connect a crank shaft 6 with the fuel injection pump 30 for constructing a fuel injection angle control device 4. Meanwhile, a can shaft 9 is provided on the same axis of the cam shaft gear 8, and a roller 37 to be rolled in touch with a cam of the said shaft 9 is supported against an eccentric shaft 39 whose eccentricity is changed by a control motor 41 for constructing a valve opening/closing angle control device 5. Control motors 14 and 41 of control devices 4 and 5 are feedback controlled by a microcomputer 3 to obtain the optimum ignition timing and valve opening/ closing angle looked for in accordance with the detected signal of an engine load. |
