International ClassF01L 013/02Foreign Application Priority Data1990-03-13 CAAbstractA reversing internal combustion engine has an ignition system controlled by a microprocessor which samples the magneto voltage output in order to make decisions concerning spark/timing. By suppressing the spark to allow the engine to slow down, and reapplying the spark at a suitable advance, reversal of the engine is effected from forward to reverse or reverse to forward. | |
