Characterization of spark ignition energy transfer at different phases using pressure-rise calorimetry
The paper presents novel studies on the electrical-to-thermal energy deposition to gas at different phases of a spark. The experiments utilized a 10.9 milliliter custom-built spark calorimeter. The energy transfer efficiencies across spark phases—breakdown+arc, and glow are quantified, emphasizing their importance in ensuring robust ignition. An AC capacitive ignition system was considered in the
