PURPOSE:To achieve a highly accurate fuel injection in the low intake by correcting an intake detection signal with a revolutions detection signals as variables. CONSTITUTION:A fuel injection valve 2 is arranged in an engine 1 as illustrated. In addition, an intake sensor 3 is provided in an air cleaner 12 provided on the upstream and the output thereof inputted into a control unit 5. On the other hand, the revolutions of the engine 1 are detected with an ignition coil 4 and calculated with the unit 5. In the drawing, the numeral 6 indicates a tank, 7 a pump, 8 a filter and 9 a regulator. An analog signal such as intake detection signal is inputted into an A/D converter A/D of a control unit CL and a digital signal such as revolutions detection signal into a digital processing circuit IO or a switching signal into a DIO. The CL performs a data processing and a program processing with a CPU and a ROM to determine a pulse width to be outputted to a fuel injection valve INJ and outputs a control pulse from an output control stage 00. |
