Turbocharge
In an internal combustion engine, a turbocharger (often called a turbo) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress 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 turbocharger is powered by the kinetic energy of the exhaust gasses, whereas a is mechanically powered (usually by a belt from the engine's crankshaft). However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. History Prior to the invention of the turbocharger, |

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. D ...

Alfred Büchi
Alfred Büchi (July 11, 1879 – October 27, 1959) was a Swiss engineer and inventor. He was best known as the inventor of turbocharging. Büchi was born July 11, 1879, in Winterthur, Switzerland, growing up there and in Ludwigshafen. He was the son of Johann Büchi, a chief executive at Swiss industrial engineering and manufacturing firm Sulzer. He was well-positioned to pursue a similar field and would eventually achieve fame as a result of his inventions. In 1899 he enrolled as a machine engineering student at Federal Polytechnic Institute (ETH) in Zürich, receiving a degree in 1903. From there he practised engineering in Belgium and England before returning to Switzerland ( Wetzikon) in 1908. The turbocharger During his early years outside Switzerland, Büchi became fascinated with the challenge of improving combustion engine efficiency relating to exhaust heat loss. Büchi's patents Büchi's patent, No. 204630 received from the Imperial Patent Office of the Ger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chevrolet Corvair
The Chevrolet Corvair is a compact car manufactured by Chevrolet for model years 1960–1969 in two generations. A response to the Volkswagen Beetle, it remains the only American-designed, mass-produced passenger car with a rear-mounted, air-cooled engine. The Corvair was manufactured and marketed in 4-door sedan, 2-door coupe, convertible, 4-door station wagon, passenger van, commercial van, and pickup truck body styles in its first generation (1960–1964) and as a 2-door coupe, convertible or 4-door hardtop in its second (1965–1969) – with a total production of approximately 1.8 million from 1960 until 1969. The name "Corvair" originated as a portmanteau of Corvette and Bel Air, a name first applied in 1954 to a Corvette-based concept with a hardtop fastback-styled roof, part of the Motorama traveling exhibition. When applied to the production models, the "air" part referenced the engine's cooling system. A prominent aspect of the Corvair's legacy derives fr ...

Oldsmobile Jetfire
The Oldsmobile Cutlass was a series of automobiles produced by General Motors' Oldsmobile division between 1961 and 1999. At its introduction, the Cutlass was Oldsmobile's entry-level model; it began as a unibody compact car, but saw its greatest success as a body-on-frame intermediate. The Cutlass was named after the type of sword, which was common during the Age of Sail. Introduced as the top trim level in Oldsmobile's compact F-85 Series, the Cutlass evolved into a distinct series of its own, spawning numerous variants, including the 4-4-2 muscle car in 1964, premium Cutlass Supreme in 1966, and outright performance Hurst/Olds in 1968, as well as the Vista Cruiser station wagon. By the 1980s, Oldsmobile was using the Cutlass as a sub-marque, with numerous vehicle lines bearing the name simultaneously. These included the Cutlass Calais compact, the midsize Cutlass Ciera, the Cutlass Cruiser station wagon, and top-of-the-line midsize Cutlass Supreme. Origins Olds ...

Centrifugal Compressor
Centrifugal compressors, sometimes called impeller compressors or radial compressors, are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. They achieve pressure rise by adding energy to the continuous flow of fluid through the rotor/impeller. The following equation shows this specific energy input. A substantial portion of this energy is kinetic which is converted to increased potential energy/static pressure by slowing the flow through a diffuser. The static pressure rise in the impeller may roughly equal the rise in the diffuser. Equation-0.1 : H = \left( \left( R \right)_2 - \left( R \right)_1 \right) :where the control volume nomenclature (illustrated in Figure-0.4) is: ::* subscript, is the impeller inlet location, station1 ::* subscript, is the impeller discharge/exit location, station2 ::* is the energy input per unit mass, units=(LP/m) ::* is the impeller's rotation speed, units=(radians/t) ::* is the radius of specified location, units=(L) ::* is ve ...

Forced Induction
In an internal combustion engine, forced induction is where turbocharging or supercharging is used to increase the density of the intake air. Engines without forced induction are classified as naturally aspirated. Operating principle Overview Forced induction is often used to increase the power output of an engine. This is achieved by compressing the intake air, to increase the mass of the air-fuel mixture present within the combustion chamber. A naturally aspirated engine is limited to a maximum intake air pressure equal to its surrounding atmosphere; however a forced induction engine produces "boost", whereby the air pressure is higher than the surrounding atmosphere. Since the density of air increases with pressure, this allows a greater mass of air to enter the combustion chamber. Theoretically, the vapour power cycle analysis of the second law of thermodynamics would suggest that increasing the mean effective pressure within the combustion chamber would also increa ...

Republic P-47 Thunderbolt
The Republic P-47 Thunderbolt is a World War II-era fighter aircraft produced by the American company Republic Aviation from 1941 through 1945. It was a successful high-altitude fighter and it also served as the foremost American fighter-bomber in the ground-attack role. Its primary armament was eight .50-caliber machine guns, and it could carry 5-inch rockets or a bomb load of . When fully loaded, the P-47 weighed up to 8 tons, making it one of the heaviest fighters of the war. The Thunderbolt was effective as a short-to medium-range escort fighter in high-altitude air-to-air combat and ground attack in both the European and Pacific theaters. The P-47 was designed around the powerful Pratt & Whitney R-2800 Double Wasp 18-cylinder radial engine, which also powered two U.S. Navy/U.S. Marine Corps fighters, the Grumman F6F Hellcat and the Vought F4U Corsair. An advanced turbosupercharger system ensured the aircraft's eventual dominance at high altitudes, while also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbine
A turbine ( or ) (from the Greek , ''tyrbē'', or Latin ''turbo'', meaning vortex) is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced by a turbine can be used for generating electrical power when combined with a generator.Munson, Bruce Roy, T. H. Okiishi, and Wade W. Huebsch. "Turbomachines." Fundamentals of Fluid Mechanics. 6th ed. Hoboken, NJ: J. Wiley & Sons, 2009. Print. A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor. Early turbine examples are windmills and waterwheels. Gas, steam, and water turbines have a casing around the blades that contains and controls the working fluid. Credit for invention of the steam turbine is given both to Anglo-Irish engineer Sir Charles Parsons (1854–1931) for invention of the reaction turbine, ...

Engine Displacement
Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. It is commonly used as an expression of an engine's size, and by extension as a loose indicator of the power an engine might be capable of producing and the amount of fuel it should be expected to consume. For this reason displacement is one of the measures often used in advertising, as well as regulating, motor vehicles. It is usually expressed using the metric units of cubic centimetres (cc or cm3, equivalent to millilitres) or litres (l or L), orparticularly in the United States cubic inches (CID, cu in, or in3). Definition The overall displacement for a typical reciprocating piston engine is calculated by multiplying together three values; the distance travelled by the piston (the stroke length), the circular area of the cylinder, and the number of cylinders in the whole engine. The formula is: : \text = \text \times \frac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sanford Alexander Moss
Sanford Alexander Moss (August 23, 1872 – November 10, 1946) was an American aviation engineer, who was the first to use a turbocharger on an aircraft engine. Life and career Sanford Moss was born 1872 in San Francisco, California to Ernest Goodman Moss and Josephine Sanford. He received his B.S. and M.S. in engineering from the University of California, San Francisco. On August 23, 1899, he married Jennie Edith Somerville Donnely in Chicago, Illinois. Moss received his Ph.D. from Cornell University where he built his first gas turbine engine. In 1903 after graduation, Moss became an engineer for General Electric's Steam Turbine Department in Lynn, Massachusetts.Leyes, p.231-232. At GE he worked with Elihu Thomson, Edwin W. Rice, and Charles Steinmetz. While there, he applied some of his concepts in the development of the turbosupercharger. His design used a small turbine wheel, driven by exhaust gases, to turn a supercharger. In autumn of 1917 William F. Durand, Directo ...

Internal Combustion Engine
An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high- temperature and high- pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons (piston engine), turbine blades ( gas turbine), a rotor (Wankel engine), or a nozzle (jet engine). This force moves the component over a distance, transforming chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to. This replaced the external combustion engine for applications where the weight or size of an engine was more important. The first commercially successful internal combustion engine was created by Étienne Lenoir around 1860, and the first modern internal combustion engine, ...
