Observation of Ignition Process in Micro Wave-Assisted Plasma Combustion Engine
Published September 29, 2010 by Society of Automotive Engineers of Japan in Japan
The ignition process is an extremely important process in a spark ignition engine where the success or failure of combustion afterwards is decided. In this study, it has aimed to investigate the ignition process of the new ignition system that adds the micro wave (MW) to the electrical discharge spark ignition system. Using the compression-expansion engine, flame kernel formation process was observed and the relation between the micro wave turning on time and the ignition time was investigated. As a result, some of the demand for ignition at initial ignition stage, area of initial flame core, thickness of initial flame core, etc., were found and MW plasma is useful especially for ultra lean mixture condition.
