Wankel Engine
The Wankel engine (, ) is a type of internal combustion engine using an eccentric rotary design to convert pressure into rotating motion. It was invented by German engineer Felix Wankel, and 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 rotates inside an oval-like epitrochoidal housing, around a central output shaft. The rotor spins in a hula-hoop fashion around the central output shaft, spinning the shaft via toothed gearing. Due to its inherent poor thermodynamics, the Wankel engine has a significantly worse thermal efficiency and worse exhaust gas behaviour when compared against the Otto engine or the Diesel engine, which is why the Wankel engine has seen limited use since its introduction in the 1960s. However, its advantages of compact design, smoothness, lower weight and less parts over the aforementioned reciproca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Racing Car
Auto racing (also known as car racing, motor racing, or automobile racing) is a motorsport involving the racing of automobiles for competition. Auto racing has existed since the invention of the automobile. Races of various sorts were organised, with the first recorded as early as 1867. Many of the earliest events were effectively reliability trials, aimed at proving these new machines were a practical mode of transport, but soon became an important way for automobile makers to demonstrate their machines. By the 1930s, specialist racing cars had developed. There are now numerous different categories, each with different rules and regulations. History The first prearranged match race of two self-powered road vehicles over a prescribed route occurred at 4:30 A.M. on August 30, 1867, between Ashton-under-Lyne and Old Trafford, a distance of eight miles. It was won by the carriage of Isaac Watt Boulton. Internal combustion auto racing events began soon after the construct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mean Effective Pressure
The mean effective pressure (MEP) is a quantity relating to the operation of a reciprocating engine and is a measure of an engine's capacity to do work that is independent of engine displacement.Heywood, J. B., "Internal Combustion Engine Fundamentals", McGraw-Hill Inc., 1988, p. 50 When quoted as an ''indicated mean effective pressure'' (''IMEP''), it may be thought of as the average pressure acting on a piston during the different portions of its cycle. Derivation Let: :W = work per cycle in joule; :P = power output in watt; :p_\text = mean effective pressure in pascal; :V_\text = displacement volume in cubic metre; :n_\text = number of revolutions per power stroke (for a 4-stroke engine, n_\text =2);Wankel engines are four-stroke engines, so n_\text =2; the displacement V_\text is derived from the chamber volume V_\text by multiplying it with the number of rotary pistons i and 2: V_\text = 2 V_\text i (see Wolf-Dieter Bensinger: ''Rotationskolben-Verbrennungsmotoren'', Spring ...

NSU Spider
The NSU Spider is an automobile which was produced by NSU Motorenwerke AG from 1963 to 1967. The Spider was the first Western production car in the world to be powered by a Wankel rotary engine. The water-cooled single rotor engine and standard front disc brakes differentiated the car from other cars of similar type of the period. The body was designed by Bertone. Body First appearing in 1963, the Spider featured a two-door cabriolet body based on that of the NSU Sport Prinz coupé introduced in 1959. In addition to the folding roof, the Spider was distinguishable from the hard top car by a grill at the front. As with all NSU cars at the time, the engine was rear-mounted: in order to improve weight distribution, space was found for the Spider’s radiator and for its fuel tank ahead of the driver. The front luggage locker was, in consequence, small. There was a second luggage area in the rear of the car above the engine. Rotary engine The NSU Spider is the first series ...

NSU Delphin III
The NSU Delphin III streamliner motorcycle set the motorcycle land speed record in 1956. Wilhelm Herz rode the machine to at Bonneville Speedway in Utah, to break 200 mph (320 km/h) for the first time. Its fairing, designed in a wind tunnel at University of Stuttgart (then Stuttgart Technical College), gave it a drag coefficient of 0.19. The same engine powered Herz to a 1951 world speed record, with a less efficient frame/fairing, the ''Delphin I''. The engine used an unusual rotary supercharger related to NSU's eventual development of the Wankel engine. In the supercharger, both a trochoidal inner rotor and epitrochoid In geometry, an epitrochoid ( or ) is a roulette traced by a point attached to a circle of radius rolling around the outside of a fixed circle of radius , where the point is at a distance from the center of the exterior circle. The parametric ...al outer rotor spun around a stationary shaft. References External links * from Technikmuseum Spey ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supercharger
In an internal combustion engine, a supercharger compresses the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a supercharger is a form of forced induction that is mechanically powered (usually by a belt from the engine's crankshaft), as opposed to a turbocharger, which is powered by the kinetic energy of the exhaust gasses. However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. The first supercharged engine was built in 1878, with usage in aircraft engines beginning in the 1910s and usage in car engines beginning in the 1920s. In piston engines used by aircraft, supercharging was often used to compensate for the lower air density at high altitudes. Supercharging is less commonly used in the 21st century, as manufacturers have shifted to turbochargers to reduce fuel consumption and/or increase power outputs. ...

NSU Motorenwerke
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. History Origin NSU originated as the "Mechanische Werkstätte zur Herstellung von Strickmaschinen", a knitting machine manufacturer established in 1873 by Christian Schmidt, a technically astute entrepreneur, in the town of Riedlingen on the Danube. The business relocated in 1880 to Neckarsulm. There followed a period of rapid growth and in 1886, the company began to produce bicycles, the first of them a 'high wheeler' or 'Penny-farthing' branded as the "Germania". By 1892, bicycle manufacturing had completely replaced knitting machine production. At about this time, the name NSU appeared as a brand name. The first NSU motorcycle appeared in 1901, ...
