Turbocharging
In an internal combustion engine, a turbocharger (also known as a turbo or a turbosupercharger) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake air, forcing more air into the engine in order to produce more power for a given displacement. Turbochargers are distinguished from superchargers in that a turbocharger is powered by the kinetic energy of the exhaust gases, 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.

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 incre ...

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 German ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chevrolet Corvair
The Chevrolet Corvair is a Rear-engine design, rear-engined, Chevrolet Turbo-Air 6 engine, air-cooled compact car manufactured and marketed by Chevrolet over two generations between 1960 and 1969. A response to the Volkswagen Beetle, it was offered in 4-door sedan, 2-door coupe, convertible and 4-door station wagon in its first generation (1960–1964), and as a 2-door coupe, convertible or 4-door hardtop in its second (1965–1969). It was also offered as a subseries known as the Chevrolet Corvair 95, Corvair 95 (1961–1965), which consisted of a passenger van, commercial van, and pickup truck variant. Total production was approximately 1.8 million vehicles from 1960 until 1969. The name "Corvair" was first applied in 1954 to a Corvette-based concept with a hardtop fastback-styled roof, part of the General Motors Motorama, Motorama traveling exhibition. When applied to the production models, the "air" part referenced the engine's cooling system. A prominent aspect of the Cor ...

Boeing B-17 Flying Fortress
The Boeing B-17 Flying Fortress is an American four-engined heavy bomber aircraft developed in the 1930s for the United States Army Air Corps (USAAC). A fast and high-flying bomber, the B-17 dropped more bombs than any other aircraft during World War II, used primarily in the European Theater of Operations, United States Army, European Theater of Operations. It is the List of most-produced aircraft, third-most produced bomber in history, behind the American four-engined Consolidated B-24 Liberator and the German multirole, twin-engined Junkers Ju 88. The B-17 was also employed in transport, anti-submarine warfare, and search and rescue roles. In a USAAC competition, Boeing, Boeing's prototype Model 299/XB-17 outperformed two other entries but crashed, losing the initial 200-bomber contract to the Douglas B-18 Bolo. Still, the Air Corps ordered 13 more B-17s for further evaluation, which were introduced into service in 1938. The B-17 evolved through numerous Boeing B-17 Flyin ...

1968 Indianapolis 500
The 52nd International 500 Mile Sweepstakes was held at the Indianapolis Motor Speedway in Speedway, Indiana on Thursday May 30, 1968. Bobby Unser won the first of his three Indy 500 victories (1968, 1975, 1981). This was the final Indianapolis 500 to feature a front-engined car in the starting field. Of the 33 cars, 32 were rear-engined machines (including three turbines). Jim Hurtubise's entry, which dropped out after only nine laps, was the last front-engine car to race in the 500. This was also the first 500 won by a turbocharged engine. For the second year in a row, one of Andy Granatelli's STP Turbine-powered machines was leading late in the race, but once again, it failed within sight of victory. On lap 174, Lloyd Ruby's engine misfired allowing Joe Leonard to take the lead in the Lotus 56 Turbine. Leonard, however, suffered a flameout on the lap 191 restart, and rolled to a silent and shocking halt. Unser, in the venerable piston-powered Offenhauser, inherited ...

Saurer
Adolph Saurer AG was a Swiss manufacturer of embroidery and textile machines, trucks and buses under the Saurer and Berna (beginning in 1929) brand names. Based in Arbon, Switzerland, the firm was active between 1903 and 1982. Their vehicles were widely used across mainland Europe, particularly in the interwar period. History In 1853 Franz Saurer (1806–1882) from Veringenstadt, Germany established an iron foundry for household goods near the Swiss town of Sankt Gallen. Eastern Switzerland was a center for both embroidery and embroidery machine development. In approximately 1850, Franz Rittmeyer built the first practical satin stitch embroidery machine, known as the '' Handstickmaschine''. Several Swiss companies began building and improving these machines, their heyday lasting from roughly 1865 until the end of the century. Two of Franz Saurer's sons – Anton and Adolph – were aware of this invention, saw an opportunity, and began building hand embroidery machines in ...
