摘要： A spark plug coil assembly includes a primary core inside a secondary winding spool that is formed with a closed end. A terminal is embedded in the closed end of the spool and the secondary windings are terminated to the terminal, with the terminal being couplable to a spark plug. Ignition voltage generated in the secondary windings is thus routed to a center of the secondary windings to terminate at the terminal. No pole piece need be disposed between the primary core and the closed end of the spool.

摘要： A suppressor diode for use in an ignition coil, the suppressor diode provides a diode that prevents “make voltages” from breaking down a spark gap of a spark plug. In addition, the resistive inductor prevents electromagnetic interference from the spark plug. The suppressor diode is configured for securement in a confined area of an ignition coil. In particular, the suppressor diode is located between a high-voltage terminal and a high-voltage end of a secondary coil. The suppressor diode includes a spool with a winding surface, a diode is molded into the spool and the diode has a first end connection and a second end connection. The diode is oriented to prevent current flow from the first end connection to the second end connection. A suppressive winding is disposed on to the winding surface, an end cap electrically connects the first end connection of the diode to the suppressor winding. A first termination electrically connects the suppressor winding to a high-voltage end of a secondary winding and a second termination electrically connects the second end of the diode to a high-voltage terminal of the ignition coil.
