Carnot cycle is effective for the purpose of understanding its principle for students. The video contents dealing with the principle of the Carnot cycle were already developed elsewhere. However, the current of video contents is a streaming image depending on the magnetic tape, and it is difficult to control freely the speed and the directions of the reproduction of the animation of video contents. On the other hand, CG animation contents are superior to video contents in controlling the speed and the directions of reproducing them according to student's understanding level. For such reasons, CG animation multi-media contents of the Carnot cycle engine which support teacher's explanation and help the understandings of its principle for students were developed and tested in a class of thermodynamics of engineering and the learning effects were examined by the questionnaire analysis.
