Benz Bz.IIIb

The Benz Bz.IIIb was an eight-cylinder, water-cooled, V-engine developed in Germany for use in aircraft in 1918.

Design and development

Inspired by the Hispano-Suiza 8, some of which were captured and tested, the Benz Bz.IIIb was a fairly large engine, but its performance was disappointing. Despite not being accepted for service use, a number of late World War I prototype German aircraft used the Bz.IIIb, the Benz IIIbo and the geared Benz IIIbm. The latter suffered vibration problems.
