Abstract
An ignition coil for an internal combustion engine includes a magnetically-permeable core a primary winding disposed outward of the core, and a secondary winding disposed outward of the primary winding and inductively coupled to the primary winding. The secondary winding has a left secondary winding section and right secondary winding section. A first end of the left secondary winding section is in electrical contact with a first terminal for delivering a first spark-generating current to a first spark plug. A first end of the right secondary winding section is in electrical contact with a second terminal for delivering a second spark-generating current to a second spark plug. A second end of the first secondary winding and a second end of a the second secondary winding is connected to a third terminal for delivering a third spark-generating current to a third spark plug.
