Abstract
A module for use in the ignition system of a spark ignited engine combines in one unit a spark plug connector or cap and an ignition coil for converting low voltage current changes into the high voltage pulses required for firing the associated plug, the module, therefore, eliminating the need for a separate high-tension conductor of substantial length between the ignition coil and the spark plug. The module is mounted to an engine shroud directly outboard of the spark plug so as to electrically cooperate with the plug while nevertheless not relying on the plug for its structural support.
