What is Flame initiation and development from glow discharges—Effect of electrode deposits about?
The predominant discharge mode in the spark from a conventional automobile coil ignition system is a glow discharge. It is also known that certain gasoline additives--alkali and alkaline earth metal compounds known as "spark-alders"--enhance the ignition process in spark ignition engines by forming deposits on the spark plug electrodes. This work describes experiments performed in a combustion bomb to study flame initiation and development from glow discharges, and the effects of electrode deposits on these phenomena. The two phenomena, which are intimately linked, are shown to be profoundly influenced by the presence of electrodes and to depend on electrode gap, material, shape and size as well as spark power, energy, mixture characteristics, and pressure. Marginal conditions for flame initiation can result from a suitable combination of any of these parameters. Crystalline deposits on the electrodes make breakdown of the gap easier and more repeatable, but breakdown itself plays a relatively unimportant role in flame initiation and development in the experiments described here. Only the potassium compound deposits on the electrodes lead to a reduction in the glow voltage, primari
