Mercedes D.IV
From Wikipedia, the free encyclopedia
The Mercedes D.IV was a 8-cylinder, liquid cooled inline aircraft engine built by Daimler and used on a small number of German aircraft during World War I. The design was based around the pistons of the ubiquitous D.III 6-cylinder design and developed 162 kW (217 hp), making it a Class IV motor under the classification system then in use in Germany. When the reliability of the engine proved disappointing, it was supplanted in production by the unrelated 6-cylinder Mercedes D.IVa.
