Abstract (en)
[origin: EP0520492A2] Spark plug apparatus includes a spark-enhancing construction operative during the time between sparks to create spark-enhancing conditions for the sparks. In one type of construction, a corona wind is produced in the air gap to direct the ignited mixture away from both electrodes in order to reduce heat loss from the ignited mixture by heat transfer to the electrodes. In a second type of construction, a plasma cloud is produced in the air gap enhancing the production of the sparks.
