Shock tubes have been applied to ignition research for a long time, because they can heat a combustible fuel mixture instantaneously to high temperatures and pressures. In recent years, the shock tube studies have gained attention as they could observe not only high-temperature ignition but also low-temperature ignition, due to the improvement of the equipment and novel experimental techniques. As a result, it became an effective tool for solving various problems of internal combustion engines such as knock phenomenon of gasoline engines and HCCI combustion. In the present paper, I introduce a high-pressure shock tube capable of observing low-temperature ignition, and have reported some results of our ignition research obtained since 2007. In order to aid future shock tube studies, the issues of the high-pressure shock tube and their latest solutions are also mentioned.
