摘要： An ignition system for a multi-cylinder internal combustion engine eliminates high-voltage cables and a mechanical distributor in order to reduce electrical power losses due to joule effect caused mainly by the high voltage circuit, comprises a plurality of ignition coils and plugs, one provided for each cylinder, a distribution unit for distributing advance-angle control signals into the respective cylinders, and a booster for boosting the supply voltage in order to reduce the size of the ignition coil, in addition to the conventional ignition system. Furthermore, the ignition coil can be built integrally with the ignition plug for eliminating high-voltage cables connected between coil and plug.
