It is thought that the innovation of ignition system becomes more important toward the realization of ultra-lean combustion for gasoline engine. In this study, High Speed Plasma Ignition as the new ignition system for internal combustion engine was investigated. The high speed plasma is non-thermal plasma formed by impression of a high voltage with ultra-short duration between coaxial cylindrical electrodes. As the result of verification experiment by using a single-cylinder engine, a volumetric ignition with low energy consumption was realized. Also, an improvement of ignitability in comparison with a conventional spark plug was confirmed.
