PURPOSE:To work for a stabilized air-fuel ratio eliminating the influence of a momentary intake pulse by providing an operational device producing a fundamental jet pulse with the first and second pulse generating circuits. CONSTITUTION:The first pulse generating circuit 4 operating by the rotary signals L or H from a rotary signals generating circuit 3 synchronizing the output voltage V(I) of a linearizing circuit 2 proportionating the output voltage VS of a hot-wire flow meter 1 to an intake air quantity G and the ignition signals (a) to the motor rotation is provided. When the rotary signals (b) change from L into H, the output current of linearizing circuit 2 flows to the base of transistor (not shown), the charging current in proportion to the output current I to an integration condenser (not shown) to make a stored charge quantity equal to the integration value of the intake air quantity. The second pulse (h) through the second pulse generation circuit 5 follows to the first pulse, the width thereof is in proportion to that of the first pulse to constitute the fundamental jet pulses (i) linking with both pulses. |
