	Wankel engine
		The German firm NSU supported Wankel a lot and 1967 the fist car using a Wankel engine, the NSU Ro 80, was produced (See biography Wankel).
		In the center of the epitrochoidal housing is an eccentric cam (emphasis and fulcrum not in same place).
		The wankel engine was developed in the 70's by many companies, e.g.

	Wankel Engine - BikersUnite (Site not responding. Last check: )
		Since the Wankel output shaft is geared to spin at three times the rotor speed, this becomes one combustion 'stroke' per output shaft revolution per rotor, twice as many as the four-stroke piston engine, and similar to the output of a two stroke cycle engine.
		Wankel engines also generally have a much higher redline than a similarly sized reciprocating engine since the strokes are completed with a rotary motion as opposed to a reciprocating engine with must use connecting rods and a crankshaft to convert reciprocating motion into rotary motion.
		The design of the Wankel engine requires numerous sliding seals and a housing that is typically built as a sandwich of cast iron and aluminum pieces that expand and contract by different degrees when exposed to heating and cooling cycles in use.

	Quasiturbine> Theory> Wankel Differences
		The Wankel explanation attempt based on centrifugal in-homogeneous mixture (or high gas speed at peripheral) is in contradiction in rotary engines, with the gas rolling mixing effect between the two near surfaces moving one in relation to the other.
		The Wankel residual geometric Vmin is substantial and 3/4 of this residual Vmin is swept during the stroke.
		The center of mass of the Wankel triangular piston is moving in circle with the crank, and this whole triangular mass tends to bang the seals against the housing, requiring the protection of a housing synchronization gear.

	The Wankel Engine History
		But it was not until the 1950s, when Wankel began collaboration with German car and motorcycle manufacturer NSU, that the Wankel rotary was developed to the point of actually being useable in a motor vehicle.
		Wankel thoroughly investigated shapes for both the rotor and the housing of the engine to bear his name, discovering over 800 possible shapes.
		It was thought that no Wankel could meet current California emissions requirements, but Mazda engineers persevered and met those stringent regulations, primarily by reconfiguring the design so that the intake and exhaust ports are on the sides of the RX-8's chamber instead on the periphery.

	Why QT is not a Wankel engine
		The Wankel engine is based on the principle of volume variation between a curve and a moving cord (a sliding single piston-object on the curve).
		Now, observe the residual minimum volume in the Wankel at TDC (which can not be reduced due to the Wankel concept geometry), and notice its variation during the strokes as the apex seal move into this minimum volume area.
		The center of mass of the Wankel triangular piston is moving in circle with the crank, and this whole triangular mass bangs the seals against the housing, requiring the protection of a housing synchronization gear.

	cars - Mazda Wankel engine (Site not responding. Last check: )
		All Mazda Wankel "rotary" engines are essentially a single family - they all derive from the first Wankel experiments in the early 1960s.
		Wankel engines can be classified by their rotor size in terms of width (diameter) and depth (thickness).
		This was the only production Mazda Wankel with different rotor dimensions: Diameter was 120 mm (4.7 in) and offset was 17.5 mm (0.7 in), but depth remained the same as the 10A at 60 mm (2.4 in).

		Wankel was born in 1903 in Lahr in the Schwarzwald.

	The OS-Graupner Wankel engine
		The Wankel was also used in motorcycles, generator units, airplanes, boats, as an auxiliary engine for sailplanes, and even a very large Wankel for use in tanks was developed.
		The OS Wankel sounds more like a 2-cycle model engine than like a 4-cycle one, but specially at idle speed the sound is dominated by the grinding noise of the rotor gearing.
		The only way a Wankel could approach a piston engine in efficiency would be by using materials that either are thermally nonconductive (impossible for now), or by operating the entire engine at such a temperature that little heat is extracted from the gases.

	The Wankel Rotary Engine
		Felix Wankel (who hailed from Swabia, Germany, the same region as famous auto designers Otto, Daimler, and Benz) basically took the principle of the internal combustion engine, and fixed the ridiculously counterintuitive features of the original design.
		During the depression and inflation of the 20’s Wankel was very much a national socialist, was in the Hitler youth, where he fell in love with his future wife; Emmy Kirn.
		The only disadvantages of the Wankel Engine are the higher emissions and low compression ratios that come from the long combustion chamber and the ineffective seals of the rotor points to the housing surfaces.

		In spring 1954 Felix Wankel in conjunction with his long time associate Ernst Höppner, realised that a triangular rotor running in an epitrochoidal bore could form the basis of a four stroke cycle engine.
		Unfortunately management had personality conflicts with Wankel so he was not invited on February 1, 1957 when the DKM 54 was fired up for the first time on the third try.
		Wankel spoke to the conference and won over the many skeptics in the audience.

	Wankel, Wankel Rotary engine, Wankel rotary aircraft engine.
		A Wankel engine has a disk,shaped like a triangle, that rotates in a circle, thus there is no top and bottom of the stroke, which practically eliminates vibration.
		The Wankel is a four stroke engine, and it is liquid cooled, the aircraft Wankel engines are unique in that they use both a charged oil lubrication system and that charged water cooled system.
		During the interview with the factor representative from Germany for Wankel the theme, reliability durability, and dependability were stressed.

	Mazda Wankel 13B Engine Aircraft Use
		Description: The Mazda Wankel 13B engine is unique in that it employs two rotors with 3 faces on each rotor which are similar in function to a reciprocating engine’s pistons.
		The Wankel engine is inherently smoother than a reciprocating engine in that there are no linear to rotational translations as exists in a reciprocating engine.
		While the upper limit estimated has varied, depending on a number of conditions, the consensus appears to be that there is no reason to expect any less than the typical 2000 hour TBO of a certified aircraft engine and some indications are that it could be as much as 4000 hours.

	Rotary History
		Since most of the Wankel patents didn't expire until the '80s, Avtovaz would probably be liable for back license fees and penalties if it or Aviadvigatel tried to sell these rotaries in the West.
		Wankel research began in China back in early 1960 (!); the paper reports a claim that over 150 "factories and research institutes" were involved with the engine in the '60s.
		Testing was rather extensive, including engines of 1 to 3 rotors, "water and air cooled, compression- and spark-ignition, with a displacement per rotor ranging from 150 to 1500 c.c." In the early '70s "common technical key difficulties" led most researchers to end their work.

		Rotary engines produced for cars today are all the Wankel type, named after the German inventor Dr. Felix Wankel.
		The Wankel is essentially a water-cooled engine with oil-cooling for the rotor.
		The turning of the flywheel goes through various gears and finally turns the wheels.All these combined with the fact that there are three power strokes for each revolution (since the cycle goes on in all three chambers simultaneously) makes the Wankel engine tremendously powerful for its size.
