ABSTRACT:
A direct ignition system includes a main high voltage coil electrically connected to a distributer which has a central pole electrically connected to the main high voltage coil for receiving a high voltage signal therefrom and rotating in concert with an engine, and a plurality of output poles spaced around the central pole and being alternately and repeatedly in electrical contact with the central pole for receiving the high voltage signal when the engine is in rotation, a control circuit comprising a plurality of identical control units each of which is electrically connected to a corresponding one of the output poles of the distributer, a plurality of high voltage coils each of which has a primary winding connected to an output terminal of one of the control units and a secondary winding connected to a corresponding spark plug. Each control unit is adapted to a preceding control unit in such a way that when one of the control units is charged at the high voltage coil thereof, the preceding control unit will enable the high voltage coil to energize the corresponding plug to ignite the corresponding cylinder.
