Message:	I found this article at autospeed.com and thought you might be interested in reading it: 'Getting the Spark!' - Crane Cams - makers of FireBall ignition systems - takes us on a quick tour of how different ignition systems work. The ignition process is key to the operation of internal combustion engines. Four-cycle engines require external combustion, and this is accomplished by discharging electrical energy through a spark gap. Heat transfer and gas ionisation (splitting apart of gas molecules) caused by the spark discharge initiates a flame kernel. The flame kernel then grows into a flame front that spreads through the combustion chamber. The stages of a spark discharge include breakdown, arc, and glow discharges.
