Abstract
An electronic ignition system for reversible internal combustion engines. The ignition system comprises a voltage generator (10, 11) for feeding the ignition circuit (12, 13) of the engine (P), a first signal pickup device (PK1) in the voltage generator (10, 11) for providing a first timing signal and a second signal pickup device (PK2) angularly spaced part in advance for providing a second timing signal to a microprocessor (18) operable to detect the direction and the speed of rotation of the engine, and to generate control signals for sparking during forward or reverse running, depending on timing information provided to the microprocessor (18) by the first and second signal pickup devices (PK1, PK2). Reversal of rotation is started by providing the microprocessor (18) with a reverse control signal by a manually actuable switch device.
