After the invention of the compressed-air engine, there have already been compressed-air car engines on the market that are both environmentally friendly and economically efficient. In order to facilitate the understanding of the emerging green energy and its applications, and in view of the lack of teaching aids for compressed-air engines, it is the purpose of this study to design and manufacture a teaching aid for compressed-air engines, thus helping students to learn the processing steps and methods of the various components of such engine, and to comprehend its working principle. The teaching aid provided in this study can be readily made in a short time, with easily available and inexpensive material. In addition, the transparent cylinder is perfect for observing engine operation. This study makes the following findings: (1) A heavier flywheel of the engine leads to a lower starting pressure, a higher pressure tolerance value of the engine, and given a fixed volume of the pressure storage tank and a constant initial pressure, a longer operating time. (2) The engine A designed in this study is capable of stable operation. The research process and results of this study not only provide directions for science projects in colleges and universities, but also serve as supplementary teaching material for physics and mechanics courses in senior high school and vocational high school. This study has potential for commercialization and can be implemented as a teaching aid and teaching material for science experiments in high school and elementary school, thereby promoting the education of green energy through compressed-air engines.
