This Design Quietly Solved the Big Problem with Radial Engines

Описание: The Zoche Aero-Diesel is almost a revival of the Packard DR-980, except Zoche actually got the Aero-diesel's design right. Not only that, they managed to make a radial engine small enough to compete with horizontally opposed engines. How did they accomplish that? Let's explore the fascinating design of the Zoche Aero-diesel.
