The Mercedes D.III was a German aircraft engine from the First World War. His first tests took place in 1914. The engine - in the D.III au version - had a weight of 310 kilograms with a displacement volume of 14.8 liters. Its maximum power reached 174 HP. It was one of the most important German aircraft engines of the late World War I period.
The Mercedes D.III was a liquid-cooled 6-cylinder in-line engine. It was created as a development of the Mercedes D.II engine. Compared to its predecessor, however, it had greater weight, cubic capacity and generated greater maximum power. It also had a fuel pump located elsewhere and of a slightly different design. However, it was based on an almost identical body, as well as duplicated many design solutions from the D.II. In the course of serial production, only a few development versions of the Mercedes D.III engine were created, such as: D.III (first production version), D.IIIa (improved model, with a maximum power of 170 HP) or D.III au (unofficial, but very often used model designation with a maximum power of 180-200 HP). Mercedes D.III engines of various versions powered such planes as, for example: AEG C.IV, Albatros CI or C.III, Fokker D.IV or D.VII or Pfalz D.III.
