Abstract
A system for the automatic recommencing of the ignition function of an i.c. engine with a computer controlled ignition system. The system includes an oscillator which occasionally can stop working. An RC-circuit is charged by ignition pulses supplied by the micro-computer and is discharged by possible failure of these pulses. A sensing circuit influenced by the RC-circuit thereby supplies a reset pulse to the computer which then recommences the supply of ignition pulses.
