Converting Wasted Spark Ignition to Sequential Spark, for High Efficiency Combustion

Last Updated on November 8, 2021 by Swagatam 37 Comments

wasted spark 1

In this post I have explained a simple method of converting a wasted spark type ignition system in an automobile, into an enhanced, sequential spark, 6 cylinder engine type ignition system. The idea was requested by Mr. Brenton, as given below: Main Requirements I was looking through the car and motorcycle section but couldn’t find […]
