An ignition coil has a capacitor for detecting ignition voltage of a spark-ignition internal combustion engine to determine if misfire occurs. The ignition coil has a primary winding and a secondary winding both wound around a core. A connector section, connected to the secondary winding by a lead, is...http://www.google.es/patents/US5461316?utm_source=gb-gplus-sharePatente US5461316 - Ignition coil with misfire detecting capacitor for internal combustion engine
