Porsche 911 GT2 RS
The Porsche 911 GT2 is a high-performance, track-focused sports car built by the German automobile manufacturer Porsche from 1993 to 2009, and then since 2010 as the GT2 RS. It is based on the 911 Turbo, and uses a similar twin-turbocharged engine, but features numerous upgrades, including engine enhancements, larger brakes, and stiffer suspension calibration. The GT2 is significantly lighter than the Turbo due to its use of rear-wheel-drive instead of all-wheel-drive system and the reduction or removal of interior components. As a result, the GT2 (now GT2 RS) is the most expensive and fastest model among the 911 lineup. 993 generation The 993 GT2 was initially built in order to meet homologation requirements for GT2 class racing. Because the cars were built to meet the GT2 class regulations, the road cars were named accordingly (but badged as the 911 GT). The 993 GT2 featured widened plastic fenders and a larger rear wing with air scoops in the struts for improved engine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porsche
Dr. Ing. h.c. F. Porsche AG, usually shortened to Porsche (; see below), is a German automobile manufacturer specializing in high-performance sports cars, SUVs and sedans, headquartered in Stuttgart, Baden-Württemberg, Germany. The company is owned by Volkswagen AG, a controlling stake of which is owned by Porsche Automobil Holding SE. Porsche's current lineup includes the 718 Boxster/Cayman, 911 (992), Panamera, Macan, Cayenne and Taycan. History Origin Ferdinand Porsche (1875–1951) founded the company called "Dr. Ing. h. c. F. Porsche GmbH" with Adolf Rosenberger and Anton Piëch in 1931. The main offices was at Kronenstraße 24 in the centre of Stuttgart. Initially, the company offered motor vehicle development work and consulting, but did not build any cars under its own name. One of the first assignments the new company received was from the German government to design a car for the people; that is, a ''Volkswagen''. This resulted in the Volkswagen Beetle ...

Twin-turbo
Twin-turbo (not to be confused with a twincharger setup, which is a combination of a supercharger and a turbocharger) refers to an engine in which two turbochargers work in tandem to compress the intake fuel/air mixture (or intake air, in the case of a direct-injection engine). The most common layout features two identical or mirrored turbochargers in parallel, each processing half of a V engine's produced exhaust through independent piping. The two turbochargers can either be matching or different sizes. Types and combinations There are three types of turbine setups used for twin-turbo setups: * Parallel * Sequential * Series These can be applied to any of the five types of compressor setups (which theoretically could have 15 different setups): * Compound Compressors * Staged Compound Compressors * Staged Sequential Compressors * Parallel Sequential Compressors * Parallel Compressors Parallel A parallel configuration refers to using two equally-sized turbochargers whi ...

Turbocharged
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,[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stroke (engine)
In the context of an internal combustion engine, the term stroke has the following related meanings: * A phase of the engine's cycle (e.g. compression stroke, exhaust stroke), during which the piston travels from top to bottom or vice versa. * The type of power cycle used by a piston engine (e.g. two-stroke engine, four-stroke engine). * "Stroke length", the distance travelled by the piston during each cycle. The stroke length––along with bore diameter––determines the engine's displacement. Phases in the power cycle Commonly used engine phases or strokes (i.e. those used in a four-stroke engine) are described below. Other types of engines can have very different phases. Induction-intake stroke The induction stroke is the first phase in a four-stroke (e.g. Otto cycle or Diesel cycle) engine. It involves the downward movement of the piston, creating a partial vacuum that draws a air-fuel mixture (or air alone, in the case of a direct injection engine) into the com ...

Bore (engine)
In a piston engine, the bore (or cylinder bore) is the diameter of each cylinder. Engine displacement is calculated based on bore, stroke length and the number of cylinders: displacement = The stroke ratio, determined by dividing the bore by the stroke, traditionally indicated whether an engine was designed for power at high engine speeds ( rpm) or torque at lower engine speeds. The term "bore" can also be applied to the bore of a locomotive cylinder or steam engine pistons. Steam locomotive The term bore also applies to the cylinder of a steam locomotive or steam engine. See also * Bore pitch * Compression ratio * 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 ... References {{Steam engine configurations Engine technology ...

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 \times ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air-cooled Engine
Air-cooled engines rely on the circulation of air directly over heat dissipation fins or hot areas of the engine to cool them in order to keep the engine within operating temperatures. In all combustion engines, a great percentage of the heat generated (around 44%) escapes through the exhaust, not through the metal fins of an air-cooled engine (12%). About 8% of the heat energy is transferred to the oil, which although primarily meant for lubrication, also plays a role in heat dissipation via a cooler. ''Air-cooled engines'' are used generally in applications which would not suit liquid cooling, as such modern air-cooled engines are used in motorcycles, general aviation aircraft, lawn mowers, generators, outboard motors, pump sets, saw benches and auxiliary power units. Introduction Most modern internal combustion engines are cooled by a closed circuit carrying liquid coolant through channels in the engine block and cylinder head, where the coolant absorbs heat, to a h ...

FIA GT2 European Championship
The FIA GT Championship was a sports car racing series organized by the Stéphane Ratel Organisation (SRO) at the behest of the Fédération Internationale de l'Automobile (FIA). The championship was mostly concentrated in Europe, but throughout the years has visited other continents including Asia and South America. At the end of 2009, the championship was replaced by the FIA GT1 World Championship, which morphed into the FIA GT Series for 2013. Regulations FIA currently defines several categories of GT cars with the top two specifications being GT1, or Grand Touring Cars, and GT2, or Series Grand Touring Cars. Each category has an annual driver champion, team champion, and manufacturer champion. Both categories are based on production road car designs, which must be produced in a minimum quantity of 25 examples to qualify. Both types may undergo significant modifications from the road car they are based on, but GT1 allows the use of exotic materials, better aerodynamics, lar ...

Homologation (motorsport)
In motorsports, homologation is the type approval process through which a vehicle, a race track, or a standardised part is required to go for certification to race in a given league or series. The process of testing and certification for conformance to technical standards is usually known as type approval in English-language jurisdictions. The regulations and rules that must be met are generally set by the series's sanctioning body. The word is derived from Greek , . When a car loses the homologation form, that is, it becomes a historic vehicle, it can no longer be part of a competition and can only be used in historic competitions. Requirements In racing series that are "production-based", meaning that the vehicles entered in the series are based on production vehicles for sale to the public, homologation not only requires compliance with a racing series's technical guidelines (for example engine displacement, chassis construction, suspension design and such), but often ...

Porsche 993
The Porsche 993 is the internal designation for the Porsche 911 model manufactured and sold between January 1994 and early 1998 (model years 1995–1998 in the United States), replacing the 964. Its discontinuation marked the end of air-cooled 911 models. The 993 was much improved over and quite different from its predecessor. According to Porsche, every part of the car was designed from the ground up, including the engineAutoTraderClassics.com — Article Finding Porsche's best road car — Porsche 911S vs 993. and only 20% of its parts were carried over from the previous generation. Porsche refers to the 993 as "a significant advance, not just from a technical, but also a visual perspective." Porsche's engineers devised a new light-alloy subframe with coil and wishbone suspension (an all new multi-link system, Weissach axle), putting behind the previous lift-off oversteer and making significant progress with the engine and handling, creating a more civilized car ...
