Abstract
PURPOSE: To simplify the circuitry of electronically controlled fuel injection system for internal combustion engine, through provision of a 1/2-pulse generating means which produces a signal for causing one injection for two turns of crank shaft.
CONSTITUTION: Revolutional number of engine, quantity of suction air and other parameters are furnished from detectors 5, 6 to control pulse generating means 1 for controlling operation of injection valve driving means 4. In the control pulse generating means 1, there are provided a wave-form shaping means 7, flip-flop 8, and circuits 9, 10 for shaping the pulse signal into 1/2-pulse signal. Signals from these two circuits 9, 10 are furnished to AND-circuit 21 via TpMAX generating circuit 19, etc., and on the basis of the output signal of circuit 21, pulse signal to be furnished to injection valves is divided into two halves.
