Development of a model car with low temperature difference Stirling Engine by using 3D printers

Abstract

In order to expand the opportunities for low temperature difference Stirling engine to be adapted to teaching material for engineering education, we tried more difficult challenge for low temperature difference Stirling engine. RC-class in Stirling Technorally is much more difficult challenge because of many functions required as the machine is required to run 50 m by radio control and rough surface of the course. So, we tried to develop a model car equipped with low temperature difference Stirling engine that can complete the RC class in Stirling Technorally. By equipping a low temperature difference Stirling engine that has arrayed plastic regenerator and continuously variable transmission manufactured by 3D printers, it could successfully complete RC-class in 26th Stirling Technorally. By this achievement, it was shown that more possibility of low temperature difference Stirling engine for education.
