Has anyone heard of Zoche diesel engines? What’s the status there? On paper they seem even better than deltahawk

None of these two stroke diesels seems to be going anywhere in the last 15-20 years. Deltahawk has been “just around the corner” for decades. They do appear to be certified a few days ago. which is a bit odd since they are targeting the experimental market.
I like the concept of the Zoche better. Aircooling should be lighter and more robust than watercooled. A radial with even number of cylinders is a bit odd, though (pun intended).
A pity it does not seem to be going anywhere
