Evaluation of Spark Plug Energy and Efficiency for Two Wheeler Ignition System 2019-26-0330

This paper describes a testing methodology to measure Spark Energy and Spark Efficiency. In addition to that the paper concludes the variable(s) affecting Spark Efficiency and Spark Energy. Ignition system plays a significant role in an efficient burning of the fuel and performance of the vehicle. Whereas, Spark Plug with Ignition system is the highest electrical energy consuming component in the vehicle electrical system. The ignition coil energy is governed by amount of the energy spark plug needs to burn the fuel. The spark plug operates in two-phases, the arc and glow phase; glow phase helps to burn the fuel whereas, arc phase initiates the spark. The experimental setup specified in this paper derived to improve available methodologies documented in current literatures. The present experimental method uses the temperature calorimeter and holographic interferometry technic. These measurement technics can lead to measurement errors. The experimental methodology in this paper includes spark ignition system similar to a vehicle with TCI control unit and also includes pressurized chamber simulating vehicle operating condition at the time of sparking. The measurement system contains ignition coil, magneto-motor unit and measurement equipment to measure energy and efficiency of the spark plug. The new experimental set up limits the measurement error and can measure arc and glow phase output energies separately. The variable studied to understand parameters affecting Spark Energy and Spark Efficiency are combustion pressure loads, condition of spark plug, configuration of spark plug, heat value, and gap between the electrodes of the spark plug. The statistical result shows combustion pressure and spark plug gap has highest influence on Spark Energy and Spark Efficiency. Other variables as specified above have minimal influence on the Spark Energy and Spark Efficiency.
