Restrictor Plate
A restrictor plate or air restrictor is a device installed at the intake of an engine to limit its power. This kind of system is occasionally used in road vehicles (e.g., motorcycles) for insurance purposes, but mainly in automobile racing, to limit top speed to provide Balance of performance, equal level of competition, and to lower costs; insurance purposes have also factored in for Motorsport, motorsports. Racing series A few top classes like Formula One limit only the displacement and air intake mouth dimension. However, in 2006 air restrictors (as well as rev limiters) were used by Scuderia Toro Rosso to facilitate the transition to a new engine formula. Many other racing series use additional air restrictors. * Formula 3, 2000cc, 215 hp * Formula SAE, 710cc, 20 mm restrictor. * Deutsche Tourenwagen Masters, 4000cc, 470 hp * FIA GT Championship (now FIA GT1 World Championship) and other series using FIA GT Championship#Regulations, FIA GT regulations * Le M ...

Petit Le Mans
Petit Le Mans (French language, French for ''Little Le Mans'') is a sports car racing, sports car Endurance racing (motorsport), endurance race held annually at Road Atlanta in Braselton, Georgia, United States. The race has been held for a duration of 10 hours since 2014, having previously been held for either or 10 hours, whichever came first. In addition to the overall race, teams compete for class victories in different categories, divided into Sports prototype, prototypes and grand tourers. The race was founded by Road Atlanta owner Don Panoz to bring the rules and spirit of the 24 Hours of Le Mans to North America. The success of the 1998 Petit Le Mans, inaugural event in 1998, held as part of the IMSA GT Championship, IMSA season with a special one-off format, led to the creation of the American Le Mans Series in 1999 with a similar formula. Petit Le Mans was a flagship event for the ALMS, which became the most prominent top-class sports car racing series during the 2000s. ...

Rev Limiter
A rev limiter is a device fitted in modern vehicles that have internal combustion engines. They are intended to protect an engine by restricting its maximum rotational speed, measured in revolutions per minute (RPM). Rev limiters are Engine control unit, pre-set by the engine manufacturer. There are also aftermarket units where a separate controller is installed using a custom RPM setting. A limiter prevents a vehicle's engine from being pushed beyond the manufacturer's limit, known as the ''redline'' (literally the red line marked on the tachometer). At some point beyond the redline, engine damage may occur. Operation Limiters usually work by shutting off a component necessary for the combustion processes to occur, whether it be fuel, air or spark. Internal combustion engine#Compression ignition process, Compression-ignition engines use mechanical Governor (device), governors or limiters to shut off electronic fuel injectors. A Internal combustion engine#Spark ignition process ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power (physics)
Power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. Power is a Scalar (physics), scalar quantity. Specifying power in particular systems may require attention to other quantities; for example, the power involved in moving a ground vehicle is the product of the aerodynamic drag plus traction (engineering), traction force on the wheels, and the velocity of the vehicle. The output power of a Engine, motor is the product of the torque that the motor generates and the angular velocity of its output shaft. Likewise, the power dissipated in an electrical element of a electrical circuit, circuit is the product of the electric current, current flowing through the element and of the voltage across the element. Definition Power is the Rate (mathematics), rate with respect to time at which work is done or, more generally, the rate of change of total mechanical energy. It is ...

Torque
In physics and mechanics, torque is the rotational analogue of linear force. It is also referred to as the moment of force (also abbreviated to moment). The symbol for torque is typically \boldsymbol\tau, the lowercase Greek letter ''tau''. When being referred to as moment of force, it is commonly denoted by . Just as a linear force is a push or a pull applied to a body, a torque can be thought of as a twist applied to an object with respect to a chosen point; for example, driving a screw uses torque to force it into an object, which is applied by the screwdriver rotating around its axis to the drives on the head. Historical terminology The term ''torque'' (from Latin , 'to twist') is said to have been suggested by James Thomson and appeared in print in April, 1884. Usage is attested the same year by Silvanus P. Thompson in the first edition of ''Dynamo-Electric Machinery''. Thompson describes his usage of the term as follows: Today, torque is referred to using d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitsubishi Lancer Evolution
The Mitsubishi Lancer Evolution, popularly referred to as the "Evo", is a sports sedan and rally car based on the Lancer that was manufactured by Japanese manufacturer Mitsubishi Motors from 1992 until 2016. There have been ten official versions to date, and the designation of each model is most commonly a Roman numeral. All generations use two-litre intercooled turbo inline four-cylinder engines and all-wheel drive systems."Development of Center-Differential Control System for High Performance Four-Wheel Drive Vehicles", Mitsubishi Motors Technology Review 2001, no.13, pp. 61–66 The Lancer was originally intended only for Japanese markets, but demand on the "grey import" market led the Evolution series to be offered through Ralliart dealer networks in the United Kingdom and in various European markets from around 1998. Mitsubishi decided to export the eighth generation Evolution to the United States in 2003 after witnessing the success Subaru had in that market the previous ...

Group N
In relation to international motorsport governed by the FIA, Group N refers to regulations providing "standard" large-scale series production vehicles for competition. They are limited in terms of modifications permitted to the standard specification by the manufacturer making them a cost effective method of production vehicle motorsport. Often referred to as the "showroom class", Group N contrasts with Group A which has greater freedom to modify and tune the cars to be more suitable to racing. Both groups may have the same or similar models homologated by a manufacturer. Group N was introduced by the FIA in 1982 to replace the outgoing Group 1 as "standard touring cars". At this time there were not specific formulae for production racing cars in competition. The World Rally Championship (WRC), for example, only permitted groups A, B and N cars to compete (Group B was banned from 1987). It was not until 1997 that the World Rally Car formula was introduced and other specific form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Rally Car
A World Rally Car is a racing automobile built to the specific regulations set by the Fédération Internationale de l'Automobile (FIA) and designed for competition in the World Rally Championship (WRC). The cars were introduced in 1997 as a replacement for Group A regulations used in the manufacturers' championship, and were replaced by Group Rally1 in 2022. Regulations 1997–2010 Between 1997 and 2010, the regulations mandated that World Rally Cars must have been built upon a production car with a minimum production run of 2500 units. A number of modifications could be made including increasing the engine displacement up to 2.0L, forced induction (including an anti-lag system), addition of four wheel drive, fitment of a sequential gearbox, modified suspension layout and attachment points, aerodynamic body modifications, weight reduction to a minimum of 1230 kg and chassis strengthening for greater rigidity. The maximum width was set at 1770 mm while front and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbocharged
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 engine displacement, displacement. Turbochargers are distinguished from superchargers in that a turbocharger is powered by the kinetic energy of the exhaust gases, 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, forced induction was only possible using mechanically-powered superchargers ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supercharged
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. It 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 gases. 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 increase power outputs, especially with reduced engine displacements.
