Zusammenfassung:Ignition apparatus for developing and applying sparks to the cylinders of an internal combustion engine (16). A plurality of secondary spark developing units (18) are respectively associated with the cylinders of the engine. Each secondary unit comprises a spark plug and a secondary winding carried by the spark 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 (10). The module has a support portion (12) and a plurality of spaced tubular members (14). A primary winding having a bore is located in each tubular member. A tubular flux carrying part formed of magnetic material is located about each primary winding. 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.
