Ignition coil with microencapsulated magnets |
摘要 |
An ignition coil for a spark ignition engine includes a cylindrical magnetic core having opposite first and second ends. Preferably, the magnetic core has a circular cross section. Permanent magnets similarly shaped as the core are disposed at the ends of the magnetic core. The magnets are made from a microencapsulated magnetic material, resulting in increased resisitivity and decreased eddy current loss. By using the microencapsulated magnets, the voltage output of the ignition coil is increased while requiring no additional input energy. A primary winding is wound about the magnetic core between the first and second ends. A secondary winding assembly is disposed about the primary winding and the core. The secondary winding assembly includes a spool and secondary winding wound thereon. The secondary winding is inductively coupled to the primary winding. An outer case is disposed about said magnetic core, magnets and the primary and secondary windings.
