Benz Bz.III
The Benz Bz.III was a six-cylinder, water-cooled, inline engine developed in Germany for use in aircraft in 1914. Developing 112 kW (150 hp) at 1,400 rpm from 14.3 L (875 cu in),[1] it powered many German military aircraft during World War I. It was replaced in production by the unrelated Benz Bz.IIIa[2].[1] and eventually the V-8 Benz Bz.IIIb. The Benz Bz.III was built under licence in Sweden by AB Thulinverken, known as the Thulin E.
