Design and development

The first known six-cylinder aircraft engine produced by Argus Motoren has been mentioned in the submissions to the Kaiserpreis contest for aviation engines which was held in 1912/13. The list of submissions states the engine having a nominal rating of , with a bore of and a stroke of .Bendemann, Seppeler, 1914, pp. 149-223 In the contest it developed at 1,370 rpm while weighing . The general design of the engine was carried over from the preceding four-cylinder Argus engines, particularly the Argus engine, with which it shared the same cylinder dimensions: the engine cylinders were of cast iron, cast in pairs of two cylinders, with the cooling jackets integral in the casting. There were two overhead valves per cylinder, which were operated via pushrods and

on the left side of the engine. The intake valves were oriented to the center of each cylinder pair, and their intake ducts were conjoined within the casting into a single external port facing to the left side of the engine. A design improvement over preceding Argus engines was the concentration of the oil pump together with the water pump and magneto at the rear of the engine. The centrifugal water pump was relocated from the left to the right side of the engine, where it was driven from the crankshaft via spur gears, with the magneto driven from the same layshaft. The oil pump was driven by the camshaft. While the engine had two spark plugs per cylinder, it still had just a single magneto, with the lack of an independent second magneto on Argus' contemporary engines being criticized in reports for the prize contest.
