Of course, there were the, under the Mercedes-license built, non-Mercedes D.III engines.
But there also was an Argus D.III engine being developed alone and not being connected to the Mercedes, and some others like the Benz D.III 180 hp.
"D.III" was just an army designation for an engine suited to fit certain demands, and those demands changed with the years.
The D.III "au" was said to run smooth at 1500 to 1700 rpm, and very rough at lower - like 1300-1400.
All not so easy to model, if you do not have access to knowledge, because it plain does not exist anymore.
This, e.g., is said to be a 200 hp engine. Certainly a D.III, but which ? Huh ?http://thevintageaviator.co.nz/projects/mercedes-engine/mercedes-engine-restoration
It entered the store without those red rings around the cylinders. From when or which engine type on were those red rings used, and did they paint it on all cylinders, of an engine having six similar cylinders ?
This is said to be a D.IIIa engine:http://s1011.photobucket.com/albums/af23...fold/?start=all
Notice the red ring, but why only on one cyl. (#1) ?
The pilots in various publications like Zuerl's "Pour le mťrite" or Langsdorff's "Flieger am Feind", pilots speak of flying Albatrosses with 200-220 hp ?
I would really like to have a complete history of, say, the Mercedes D.III without "holes" in it, from the first 140 hp D.III on.
Thanks and greetings,
