Abstract: An ignition coil for delivering a spark-generating current to a spark plug includes a magnetically-permeable core; a primary winding disposed outward of the core; and a secondary winding radially surrounding the primary winding and inductively coupled to the primary winding, the secondary winding having a low-voltage end and a high-voltage end. The secondary winding includes a secondary winding first section proximal to the low-voltage end and having a first thickness. The secondary winding also includes a secondary winding second section proximal to the high-voltage end and having a second thickness that is less than the first thickness of the secondary winding first section.

Abstract: An ignition system for a spark ignition internal combustion engine includes a transformer, a switching device, a spark-plug, and a controller. The switching-device is operable to an off-state, an on-state, and a linear-state to control a primary current through a primary coil and a secondary current through a secondary coil. The controller is configured to receive a single control-signal that includes a spark-control portion followed by a snubbing-control portion, and operate the switching-device based on the single control-signal. The controller operates the switching device from the off-state to the on-state and back to the off-state in response to the spark-control portion, whereby the secondary current is sufficient for the spark-plug to generate a spark, and operates the switching-device from the off-state to the on-state followed by the linear-state in response to the snubbing-control portion, whereby the secondary current is suppressed such that the spark-plug does not generate a spark.
