The finest miniature engines in the world

Dyno 0.25

The Swiss Dyno 2.04 was one of my favored diesel engines. The Dyno runs so smooth and what a great sound. Therefore I was wondering how a smaller scale would run. I manufactured the Dyno 0.6 ccm and now here is one size smaller the Dyno 0.25 ccm. It runs, sounds and smells great.
