This paper proposes a novel engine using periodic phase transition of matter between the liquid state and the gas state, namely geysering engine. The geysering engine consists of a closed thermosyphon, a moving part and a working fluid, and it can repeatedly operate without such mechanical structures as flywheels or cranks. Fluorinert is used as the working fluid. The amplitude and the period of pressure oscillation in a closed thermosyphon are measured to find out the characteristics of geysering in terms of an engine. In the experiments, we observed more than 10kPa pressure changes. For obtaining kinetic energy from pressure changes of geysering, we also made a simple geysering engine using a rubber balloon.
