Electronic Engine Ignition Systems
The fuel air mixture in the combustion chamber needs to be ignited at the correct moment to ensure efficient combustion and power generation by the engine. This is the job of the ignition system, be that the old fashion magneto of the good old days or a modern fully electronic microprocessor controlled FADEC system. For safety reasons the ignition system does not rely on the the aircraft electrical system and is dual and each system operates one of the two spark plugs in each cylinder.
