Powerplant of many German bombers of WWI (G and R classes).

A successful replacement for the failed Mercedes D IV engine. This time the engineers applied the proven configuration of 6 inline cylinders, and the power increase was achieved by means of enlarging the capacity of the cylinders. In order to provide adequate feeding and emptying of the cylinders, four valves per cylinder and improved inlet manifold were utilised.

The engine powered e.g. the Albatros C.X, C. XII and C.XV reconnaissance aircraft as well as Gotha, Friedrichshafen, Linke-Hofmann and Zeppelin-Staaken bombers.
