ABSTRACT:
An electronic injection-amount regulating apparatus in auto-ignited internal combustion engines in which the injection amount can be regulated by means of a regulator preferably having a PID characteristic and in which the injection amount is apportioned via a solenoid actuator and which includes a safety switching arrangement having an integral timing circuit resettable at each initiation of a control impulse for the solenoid actuator to prevent damage to the solenoid actuator in case of failure of the control signal, as well as a switching circuit for engine starting enhancement in a predetermined rpm range having as its most significant concept a series switching arrangement which includes a low-pass filter and a controllable threshold switch.
