Walter NZ 85

The Walter NZ 85 was a seven-cylinder, air-cooled, radial engine for aircraft use built in Czechoslovakia by Walter Aircraft Engines in the late-1920s.

Design and development
Using common cylinders and parts from the earlier Walter NZ 60 (Novák-Zeithammer) engine the NZ 85 and the nine-cylinder NZ 120 were designed together. Lightened and tuned developments were known as the NZ 90 and NZ 95.
