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 a transformer, an 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 the transformer, and delivers it to the spark plug upon formation of a spark.
