PURPOSE:To assure good starting performance of an engine under low temperature by providing a circuit for setting the starting fuel injection and a circuit for switching the injection signal from the output of CPU to the output of setting circuit at the specific time. CONSTITUTION:CPU1 for operating the fuel injection and a monitor WDT3 for resetting the operation of CPU under abnormality are provided. A startor contact throw-in signal of an engine keyswitch 2 and the reset signal of WDT3 are inputted through AND gate 10 to function the analog switches 11, 12 complementally. The analog switch 11 will feed the output from D/A converter 6 to a servo circuit 7 while the analog switch 12 will feed the output from starting fuel injection signal setting circuit 14 to the servo circuit 7. Consequently, good starting performance of engine under low temperature can be assured. |
