This was one of the last engines that Rudy Kouhoupt built. It serves as a nice reminder of the wide variety of projects that he was involved with. In the video below, Rudy explains what a non-compressive engine is and how it works.

One of the first large donations to the Miniature Engineering Craftsmanship Museum was the collection of famed model engine builder Rudy Kouhoupt. After retiring as a chemist, Rudy had a second career building engines and writing magazine articles documenting the process. Many people have built his models, but we have the honor of displaying all of his original prototypes. Rudy’s collection includes scale model engines, locomotives, tractors and more. Additionally, thirteen of Rudy’s model steam engines are hooked up to run on compressed air to demonstrate their function.

Another look at the Pioneer engine.
