The Wankel engine is a type of internal combustion engine using an eccentric rotary design to convert pressure into rotating motion. The concept was invented and proven by German engineer Felix Wankel, and the commercially feasible engine designed by German engineer Hanns-Dieter Paschke. The Wankel engine's rotor, which creates the turning motion, is similar in shape to a Reuleaux triangle, with the sides having less curvature. The rotor spins inside a figure-eight-like epitrochoidal housing, around a fixed toothed gearing. The midpoint of the rotor moves in a circle around the output shaft, spinning the shaft via a cam.
NSU Motorenwerke AG, or NSU, was a German manufacturer of automobiles, motorcycles and pedal cycles, founded in 1873. Acquired by Volkswagen Group in 1969, VW merged NSU with Auto Union, creating Audi NSU Auto Union AG, ultimately Audi. The name NSU originated as an abbreviation of "Neckarsulm", the city where NSU was located.
The Mazda Wankel engines are a family of Wankel rotary combustion car engines produced by Mazda.
ZF Sachs AG, also known as Fichtel & Sachs, was founded in Schweinfurt in 1895 and was a well-known German family business. At its last point as an independent company, the company name was Fichtel & Sachs AG.
A motorcycle engine is an engine that powers a motorcycle. Motorcycle engines are typically two-stroke or four-stroke internal combustion engines, but other engine types, such as Wankels and electric motors, have been used.
The Yamaha FZR1000 is a motorcycle produced by Yamaha from 1987 to 1995. Classed as a sports motorcycle.
The Suzuki RE5 is a motorcycle with a liquid-cooled single-rotor Wankel engine, manufactured by Suzuki from 1974 to 1976. Apart from its unusual engine, the RE5 is mostly a conventional roadster, albeit with some peculiar styling details thanks to Italian industrial designer Giorgetto Giugiaro.
Sachs Bikes International Company Limited is a German-based motorcycle manufacturer, founded in 1886 in Schweinfurt as Schweinfurter Präzisions-Kugellagerwerke Fichtel & Sachs, formerly known as Fichtel & Sachs, Mannesmann Sachs and later just Sachs.
Tempo was a Norwegian motorcycle and moped brand. Jonas Øglænd made the rolling chassis and most of the parts thereof, and Fichtel & Sachs AG made the engines for the majority of the models. After 1972 the company made mopeds only.
Motorcycle components and systems for a motorcycle are engineered, manufactured, and assembled in order to produce motorcycle models with the desired performance, aesthetics, and cost. The key components of modern motorcycles are presented below.
Van Veen or Van Veen Kreid is a former motorcycle manufacturer. It was founded in Amsterdam by Henk van Veen, the Dutch importer of Kreidler motorcycles.
The Norton Classic is a rotary-engined motorcycle built in 1987 by Norton as a special edition of just 100 machines.
The Suzuki Intruder is a series of cruiser motorcycles made by Suzuki from 1985 to 2005. After 2005, the Intruder lineup was replaced by the Boulevard range. In Europe, the Intruder name remains in use on certain models. The VS Intruder bikes all have 4-stroke V-twin engines.
A plenum chamber is a pressurised housing containing a fluid at positive pressure. One of its functions is to equalise pressure for more even distribution, compensating for irregular supply or demand. It is typically relatively large in volume and thus has relatively low velocity compared to the system's other components. In wind tunnels, rockets, and many flow applications, it is a chamber upstream on the fluid flow where the fluid initially resides. It can also work as an acoustic silencer.
The MidWest AE series are lightweight, liquid-cooled, single- and twin-rotor Wankel engines, with dual ignition, designed for light aircraft. They were produced by Mid-West Engines Ltd. at Staverton Airport, Gloucestershire, UK.
A total-loss oiling system is an engine lubrication system whereby oil is introduced into the engine, and then either burned or ejected overboard. Now rare in four-stroke engines, total loss oiling is still used in many two-stroke engines.
The Hercules W-2000 is a motorcycle which was made by Hercules in Germany. It was the first production motorcycle with a Wankel engine.
The Norton RCW588 is a Works Racing motorcycle, produced for the 1988 to 1994 racing seasons, initially with an air-cooled version of the road-going twin-rotor Wankel engine used in the Classic soon followed by watercooled versions from 1989.
David W. Garside is an inventor and former project engineer at BSA's Umberslade Hall research facility. He is notable for having developed an air-cooled twin-rotor Wankel motorcycle engine which powered the Norton Classic road bike. Although the Classic was not the first production rotary-engined bike, it was significantly lighter, smoother, more powerful and better-handling than the contemporary Suzuki RE5.
The Mazda HR-X was the first hydrogen powered concept car produced by Mazda. The car was unveiled at the Tokyo Motor Show in 1991. The car seated four people in a plastic shell and was powered by a two rotor Wankel engine which propelled it to 130 km/h (81 mph). The hydrogen was stored in a cooled metal hydride tank and 3.32 kilograms (7.3 lb) provided a range of 190 km (120 mi). It was the first in a series of demonstration hydrogen internal combustion engine vehicles produced by Mazda.
