"Anyone who had physics in college knows the formula for power. In this
case we're referring to ignition spark power. Power equals work
divided by time (P=W/t). Thus, to get more power, you need to do the same
amount of work in less time." Sounds simple enough! Manufacturers of
conventional ignition systems though, want you to believe that it is possible to increase the power of ignition systems by lengthening the spark duration. This is not true! Lengthening the spark duration actually reduces spark power, as we already know P=W/t (Power=Energy/Time). "
"When the spark occurs, all the thermal energy (heat) is transferred to the fuel/air mixture, where it initiates combustion. A
hotter spark will transfer more thermal energy and therefore accelerates flame front propagation. The fuel is used more efficiently and engine performance increases."
"In a spark-ignited engine, ignition normally occurs when a small portion of the mixture is caused to react by the passage of a spark at a temperature between 3000 degrees C and 6000 degrees C. The effect of heat is of SECONDARY importance, the decisive factors for initiating ignition are molecular excitation and ionization. "
