Evaluation of Spark Plug Energy and Efficiency for Two Wheeler Ignition System

The paper describes theoretical and experimental method to calculate and measure Spark Energy and Spark Efficiency. Also the paper concludes the variable(s) affecting Spark Efficiency and Spark Energy. The new method adopted has an ascendancy over the existing methods, i.e., holographic interferometry and calorimetry, the new measurement method directly measures the energy in the two sparking regions, i.e., high current and low current region. Using this method it is possible to clearly identify the influencer and the significance of the two regions of sparking. The total energy delivered by the spark plug is majorly impacted by the low current region of sparking, and the high current region has minimal impact on the same. The tenor of results from new measurement method harmonizes with the test results from existing methods for certain variants such as gap and pressure, but it disaffirms in other variants such as electrode dimensions. The reason for this disaffirmation is also addressed in this paper. The paper also studies various other variants which were not considered on in the existing method.
