ABSTRACT:
Ignition apparatus for developing and applying sparks to the cylinders of an internal combustion engine. A plurality of a secondary spark developing units are respectively associated with the cylinders of the engine. Each secondary unit comprises a spark plug and a secondary winding carried by the spark plug that is connected to the electrodes of the spark plug. Magnetic flux is coupled to the secondary winding of the secondary units by a primary winding module. The module has a support portion and a plurality of spaced tubular members. A primary coil having a bore is located in each tubular member. A tubular flux carrying part formed of magnetic material is located about each primary coil. The module is supported by the engine in such a position that portions of the secondary units project into the bores when the module is mounted on an engine.
