PURPOSE:To inject a correct fuel amount in accordance with starting operation of an engine, by using arithmetic data on the basis of an air flow amount within a prescribed time at starting of the engine and calculating the fuel feed amount from predetermined start arithmetic data. CONSTITUTION:When a starter signal is turned on by an ignition switch 2, a main arithmetic circuit 12 obtains voltage V5 by multiplying (second arithmetic operation) output of the second arithmetic circuit 13, outputting output voltage V2 inversely proportional to speed N and output voltage V12 proportional to the speed N, output of the third arithmetic circuit 14, outputting output voltage V3 on the basis of cooling water temperature T, and output voltage V4 of a timer circuit 15. On the basis of this voltage V5, a fuel injection valve 6 is controlled. While after complete explosion of the engine, output of the first arithmetic circuit 11, outputting output voltage V1 proportional to an air flow amount Q, and said output voltages V2, V12 and V3 are respectively multiplied (the first arithmetic operation) to obtain the voltage V5, on the basis of this voltage V5, the fuel injection valve 6 is similarly controlled. |
