The Argus 110 hp aircraft powerplant, also referred to as Argus Type III (distinct from As.III), was introduced circa 1912 by the German manufacturer Argus Motoren. This model featured a six-cylinder, water-cooled inline configuration.
Design and development
Argus Motoren's initial production of a six-cylinder aircraft engine is documented in the submissions for the 1912/13 Kaiserpreis aviation engine competition. According to the entry list, this engine was rated at approximately 110 hp (82 kW), with cylinder bore and stroke measuring 125 mm (4.92 in) and 130 mm (5.12 in), respectively.[1] During testing for the contest, it achieved an output of 103.5 hp (77.2 kW) at 1,370 rpm while weighing 205.55 kg (453 lb).[1]
The engine’s fundamental architecture was derived from earlier four-cylinder Argus models, notably the 70 hp (52 kW) variant, sharing identical cylinder dimensions. Cylinders were constructed from cast iron in pairs, with integrated cooling jackets within each casting. Each cylinder contained two overhead valves actuated by pushrods and rocker arms connected to a camshaft positioned on the engine’s left side. Intake valves were centrally located between each cylinder pair, combining their intake passages into a single external port oriented to the left.
A notable advancement compared to previous Argus engines was the integration of the oil pump alongside the water pump and magneto at the rear section of the unit. The centrifugal water pump was repositioned from the left to the right side of the engine and driven by spur gears linked to the crankshaft; concurrently, the magneto was powered via the same layshaft. The oil pump received its drive from the camshaft.
Although equipped with dual spark plugs per cylinder, this model retained only one magneto. The absence of a separate second magneto on Argus engines during this period drew criticism in evaluations related to the prize contest.[1]
Applications
