Measurement of CN Emissions from Engine Spark Igniter for Characterization of Spark Igniter Energy

Abstract: 

A method and system for measuring the amount of energy released by a spark ignition system. This energy can be quantified spectroscopically by measuring the emission of cyanogen radicals in the presence of a ignition event and a known A/F ratio.
