[1] Five of them powered the German airship Graf Zeppelin, housed in separate nacelles.
The engines developed 410 kW (550 hp) and were of 33.251 L (2,029.1 cu in) capacity.
[1][2] The American USS Akron used eight of them, mounted internally,[3] as did its sister ship Macon.
[4] The engines were reversible, meaning different cams could be engaged allowing the engine crankshaft to run in either direction, enabling reverse thrust.
