Abstract

PURPOSE: To promote vaporization of liquid fuel, by arranging the fuel injection timing at the end of an intake stroke in each cylinder.
CONSTITUTION: A built-in speed sensor 10 in a distributor consists of a rotor 12 and pick-up element 13 having crest parts 111W114. The crest part 111 is formed higher than the other crest parts, when this part passes through the pick-up element 13, a voltage signal of larger level is generated by the pick-up element 13 than at passing of the other crest parts. The voltage signal is input to a waveform shaper circuit 14 and control circuit 15. The signal generated from the speed sensor 10 is input to the control circuit 15 as an engine speed signal and cylinder decision signal, simultaneously a generated signal from an air flow meter is input as an intake air quantity signal, then quantity of injection fuel is decided on the basis of the engine speed signal and the intake air quantity signal. An output signal of the control device 15 shall be an output at the end of an intake stroke in a cylinder.
