 Rotary engine - Wikipedia, the free encyclopedia
The rotary engine was a common type of internal combustion aircraft engine in the early years of the 20th century.
It is a standard Otto cycle engine, but instead of having an orthodox fixed cylinder block with rotating crankshaft, the crankshaft remains stationary and the entire cylinder block rotates around it.
Most rotary engines were arranged with the cylinders pointed outwards from a single crankshaft, in the same general form as a radial, but there were also rotary boxer engines and even one cylinder rotaries.

 Gnome Monosoupape - Wikipedia, the free encyclopedia
The Monosoupape, French for single-valve, was a particular engine design used by Gnome et Rhône's later rotary engines.
Beginning with the power stroke, the four-stroke engine operated normally until the piston was just about to reach the bottom of its stroke (bottom dead center, or BDC), when the exhaust valve was opened "early".
This had to be used sparingly, as the engine would continue to pull fuel into the crank and cylinders, so turning the ignition back on after too long a period could cause the engine to explode.

 A History of Aeronautics - Chapter IV.
In 1913 the Gnome Monosoupape engine was introduced, a model in which the inlet valve to the cylinder was omitted, while the piston was of the ordinary cast-iron type.
The speed variation of this engine was obtained by varying the extent and duration of the opening of the exhaust valves, and was controlled by the pilot by hand-operated levers acting on the valve tappet rollers.
An engine of the rotary type, almost as well known as the Gnome, is the Clerget, in which both cylinders and crank case are made of steel, the former having the usual radial fins for cooling.

The engine was at this later standard when WWI started, and the Gnome quicklyfound itself being used in a large number of aircraft designs.
Although the rotary engines were mostly used in aircraft, there were also a few cars and motorcycles with rotary engines, ofwhich the most famous is the Mazda RX-7 sports car (which is followed by the Mazda RX-8, currently in production).
In 1904, the Barry engine was built in Wales, a rotating 2 cylinder boxer engine inside a motorcycle frame, weighting 6.5kg.

Notably, the fuel was mixedand sprayed into the center of the engine through a hollow crankshaft, and then into the cylinders through the piston itself, asingle valve on the top of the piston let the mixture in when opened.
Of course with no throttle, the engine was either on oroff, so something as simple as reducing power for landing required the pilot to cut the ignition, "blipping" the engine on andoff.
Another motorcycle with a radial rotary engine was the Redrup Radial, which had a rotating 3cylinder engine in its frame.

 Rotary Engine Theory - 100 hp Gnome Monosoupape
That the rotary engine dominated the early years of aviation is evident - although there were some very fine engines extant such as the twins of Duthiel-Chalmers and Darracq, the Antoinette by Levavasseur, and those of Fiat.
However, the engine also delivered sharp torque reversals when the ignition was cut which was tough on the engine mounts and the airframe.
It is arguable that the reason for cowling the engine had as much to do with trying to control the wildly spewing oil as it was to do with the concepts of streamlining.

 Rotary piston engine
:''Alternative meaning: Wankel engine or Quasiturbine The rotary engine was a common type of internal combustion aircraft engine in the early years of the 20th century.
Vibration was such a serious problem on early engines that a flywheel would otherwise have to be added as a separate block of metal, so the rotaries had a somewhat better power-to-weight ratio than other designs.
Of course with no throttle, the engine was either on or off, so something as simple as reducing power for landing required the pilot to cut the ignition, "blipping" the engine on and off.

The wing structure was of wood, whereas the fuselage frame departed from common practice in that it was constructed of welded steel tubing with wire bracing.
The horizontal and vertical tail surfaces were mounted behind the engine on an arrangement of four strut-and-wire-braced outriggers, or booms, which extended rearward from the wings.
Thus in the Camel the pilot's feet were beneath the rear components of the engine, the guns were over his legs, and the fuel tank was immediately behind his back in the fuselage.

 Internal combustion engine - Patent 4372259
Secondly, as the rotary valves are designed to run at half the engine speed, the inlet port cannot fully open until well into the intake stroke and the exhaust port has to commence closing before the end of the exhaust stroke.
Fuel for the combustion engine is fed in appropriate timed relation into the combustion chamber 14 by an injector 15 of conventional design and operated in a conventional manner known to those skilled in the art.
Differently shaped and/or constructed diverter valves may also be utilized to accomplish applicant's function of appropriately directing the flow of gases to and from the combustion chamber and from the inlet to the outlet for purging at the end of the exhaust portion of the cycle.
