Abstract
An apparatus for combustion initiation in an internal combustion engine is provided. A capacitive spark plug boot uses the engine cylinder head as an outer capacitor member. The capacitive spark plug boot contains the inner capacitor member and an insulator. The insulator surrounds the inner capacitor member, with an outer surface of the insulator sized to engage a cylinder head cavity surrounding the spark plug. The capacitor stores electrical energy received from a power source, and delivers it to the spark plug upon formation of a spark.
