ABSTRACT:
A control circuit for a fuel injection system which modifies the control pulses of the electromagnetic valves during engine starting. The width of the normal injection control pulses determines the amount of fuel and is derived from engine parameters, in particular rpm and air flow rate. When stating the engine, the control circuit is actuated by the starting switch of the engine and causes suppression of the normal control pulses. A multivibrator generates substitute starting control pulses whose duration is changed by altering the time constant of the multivibrator in response to the signal from a temperature transducer.
