Characteristics of hydrogen internal combustion Stirling engine were analyzed by comparing the engine performances on steam injection and H_2-O_2 injection. The experimental results of the steam injection showed that the internal conversion efficiency and pressure ratio increased to comparable levels with H_2-O_2 injection. Also, a two-space model predicted the concentration of steam in high temperature space to be around 3% from the pressure rises in the steam injection and the H_2-O_2 injection experiment. Simulations and estimations on these characteristics suggested a large amount of steam condensed and the condensed water evaporated at the regenerator in a cycle, leading to the conclusion that the performance improvement in the hydrogen internal combustion Stirling engine was caused by not only temperature increase in the expansion space but also the condensation-evaporation of water at the regenerator.
