摘要： An ignition apparatus includes a core, primary and secondary windings and a loop-shaped magnetic return path structure. The structure includes layers of wound strip steel or wound ferritic wire stacked in an outward fashion. The core is placed in an interior of the loop forming at least one air gap between a core end surfaces and the structure. A combined core and magnetic return path structure includes a continuous loop formed by winding ferritic wire either on a spool or on a mandrel and is then bonded. The bonded winding is cut to form two C-shaped portions. Each C-shaped portion has a central yoke that extends into a pair of parallel legs. The C-shaped portions are re-assembled over primary and second windings so that the legs form a pair of parallel branches. One branch acts as the core and the other branch acts as the magnetic return path.

摘要： An ignition apparatus having twin spark high-voltage outputs incorporates features of a pencil coil wherein at least a portion of a transformer assembly is disposed within a spark plug well when installed in an internal combustion engine, thereby reducing the space required on the top of the engine. A secondary winding spool is configured to retain a secondary winding in first and second portions, wound either the same way for use in waste spark ignition systems or in opposite orientations for two-plug-per-cylinder systems. An alternate configuration includes an isolated shield that is internal to the case.

摘要： An ignition coil cassette having bushings retained by an irregularity of the bushings being encased by epoxy. As a result, the process by which the bushings are installed into the ignition coil cassette avoids the cost associated with the overmolding installation process, and further avoids the potential for damage associated with the ultrasonic insertion process. The irregularity is located generally adjacent one end of each of the bushings and may be, for example, in the form of an undercut or a protrusion.

摘要： An ignition apparatus includes a suppression device comprising a suppression winding that is in series with the secondary winding and is further located outside of a magnetic circuit. The suppression winding is made from the same wire as used in the secondary winding and is wound on a reduced diameter portion of a secondary winding spool. A carbon resistor is disposed in series with the suppression winding in another embodiment. Nickel wire may be substituted for the suppression winding and carbon resistor in order to obtain both inductance and resistance characteristics for the suppression device.

摘要： An ignition apparatus includes a high voltage (HV) terminal to which a high voltage end of the secondary winding is attached. The ignition apparatus further includes an electrically conductive cup configured to surround the high voltage terminal when the secondary winding spool is inserted in the case. The high voltage terminal has one end that comes into engagement with an inner annular surface of the cup. Electromagnetic interference suppression is provided by a resistor disposed between the cup and a high voltage connector assembly that connects to a spark plug. The resistor is formed of electrically conductive plastic material.
