In a small-scale LNG (Liquefied Natural Gas) satellite station, a lot of cold energy is released to atmosphere when the LNG is vaporized. In order to use the cold energy effectively, we have discussed to apply a cold energy used Stirling engine generator. As the first step for the application, we operate a Stirling engine with liquid nitrogen in our laboratory. In this paper, we show the construction of the experimental Stirling engine, and report detailed experimental results of the engine using the liquid nitrogen.
