Turbocharger
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 supercharger 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,

Antar (company)
Antar is a former French petroleum company, founded by Pechelbronn SAEM in 1927 in Merkwiller-Pechelbronn, Bas-Rhin, Alsace. However, its origins go back to 1745 when a company was formed to develop the natural oil wells in the vicinity of Merkwiller-Pechelbronn. Prior to World War II it also used the brand Socaline for petrol. After the purchase of another domestic French marketer, the formal name changed to Antar Pétroles de l'Atlantique and the Antar name extended to use on fuels. Antar was largely active in France, although an affiliate had a Swiss joint venture (Socal Fina). The company may have been named after Rimsky-Korsakov's ''Antar'' Symphony about the Arab poet and warrior Antarah ibn Shaddad. In 1976 Elf-ERAP merged with Antar to form the Société National Elf Aquitaine which with over 6,000 outlets became France's second largest petrol retailer. In 2000 Elf was purchased by TotalFina (now Total S.A.). The final dissolution of the company occurred in 2005. The An ...

Manual Transmission
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canada, the United Kingdom, and the United States), or stick shift (in the United States), is a multi-speed motor vehicle transmission (mechanics), transmission system, where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually a foot pedal for cars or a hand lever for motorcycles). Early automobiles used ''sliding-mesh'' manual transmissions with up to three forward gear ratios. Since the 1950s, ''constant-mesh'' manual transmissions have become increasingly commonplace and the number of forward ratios has increased to 5-speed and 6-speed manual transmissions for current vehicles. The alternative to a manual transmission is an automatic transmission; common types of automatic transmissions are the Automatic transmission#Hydraulic automatic transmissions, hydraulic automatic transmission (AT), and the continuously variable transmissio ...
