Marcos Engineering
Marcos Engineering was a British sports car automaker, manufacturer. The name derives from the surnames of founders Jem ''Mar''sh and Frank ''Cos''tin. History Marcos was founded in Dolgellau, North Wales, in 1959, by Speedex cars' Jem Marsh with aerodynamicist Frank Costin. Costin had earlier worked on the de Havilland Mosquito fighter-bombers and from there he got the idea to use plywood for the chassis. The company moved to a converted mill in Bradford on Avon, Wiltshire, in 1963; in 1971 they relocated to a £125,000 purpose-built factory at nearby Westbury, Wiltshire, Westbury. Problems with exporting cars to the US and the move to the expensive new premises led to financial troubles, and in 1971 Marcos went out of business. In July 1971 it was reported that the Rob Walker Group of Companies, a principal dealer, had acquired the stocks and assets and established a new company, Marcos Ltd. The new owners said production would continue, albeit, at least in the short term, onl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British GT Championship
The British GT Championship is a sports car racing series based predominantly in the United Kingdom. The series was originally created by the British Racing Drivers' Club in 1993 and, for its first two seasons, was known as the National Sports GT Challenge. The series is currently run by the SRO Motorsports Group, while Pirelli began its first season as the championship's official sole tyre supplier in 2016. Two classes currently compete in the championship: GT3 and GT4. A consolidation of GT regulations and significant manufacturer support saw British GT first introduce a GT3 class in 2005. The category later mirrored FIA Group GT3 and used near-identical regulations to the FIA GT3 European Championship from 2006 onwards. GT3 rules include extensive balance of performance and handicap weights to make cars artificially more equal. Cost-saving measures saw the series' previous premier class, GT2, phased out at the end of 2006. The SRO GT4 class was adopted in 2008 intended as a d ...

Steel
Steel is an alloy of iron and carbon that demonstrates improved mechanical properties compared to the pure form of iron. Due to steel's high Young's modulus, elastic modulus, Yield (engineering), yield strength, Fracture, fracture strength and low raw material cost, steel is one of the most commonly manufactured materials in the world. Steel is used in structures (as concrete Rebar, reinforcing rods), in Bridge, bridges, infrastructure, Tool, tools, Ship, ships, Train, trains, Car, cars, Bicycle, bicycles, Machine, machines, Home appliance, electrical appliances, furniture, and Weapon, weapons. Iron is always the main element in steel, but other elements are used to produce various grades of steel demonstrating altered material, mechanical, and microstructural properties. Stainless steels, for example, typically contain 18% chromium and exhibit improved corrosion and Redox, oxidation resistance versus its carbon steel counterpart. Under atmospheric pressures, steels generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Frame
In architecture and structural engineering, a space frame or space structure (Three-dimensional space, 3D truss) is a rigid, lightweight, truss-like structure constructed from interlocking struts in a geometry, geometric pattern. Space frames can be used to span large areas with few interior supports. Like the truss, a space frame is strong because of the inherent rigidity of the triangle; flexing Structural load, loads (bending moment (physics), moments) are transmitted as tension (mechanics), tension and compression (physical), compression loads along the length of each strut. Chief applications include buildings and vehicles. History Alexander Graham Bell from 1898 to 1908 developed space frames based on tetrahedral geometry. Bell's interest was primarily in using them to make rigid frames for nautical and aeronautical engineering, with the tetrahedral kite, tetrahedral truss being one of his inventions. Mero-Schmidlin, Max Mengeringhausen developed the space grid system cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Fiber
Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers ( Commonwealth English), carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic (CFRP, CRP, CFRTP), also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications. The binding polymer is often a thermoset resin such as epoxy, but other thermoset or thermoplastic polymers, such as polyester, vinyl ester, or nylon, are sometimes used. The properties of the final CFRP product can be affected by the type of additives introduced to the binding matrix (resin). The most common additive is silica, but other ...

Rover V8 Engine
The Rover V8 engine is a compact OHV V8 internal combustion engine with aluminium cylinder block and cylinder heads, designed and produced by Rover in the United Kingdom, based on a General Motors engine. It has been used in a wide range of vehicles from Rover and other manufacturers since its British debut in 1967. History The Rover V8 began life as the Buick 215, an all-aluminium OHV pushrod engine introduced in 1960 for the 1961 US model year (it was on their drawing boards in the late 1950s). The compact alloy engine was light, at just , and capable of high power outputs: the most powerful Buick version of this engine rated , and the very similar Oldsmobile "Jetfire" turbocharged version made , both numbers SAE gross. Based on sales volume and press reports, the engine was a success. Buick produced 376,799 cars with this engine in just three years. A comparable number of Oldsmobile 215 engines were produced. In addition, some Pontiac models were fitted with the Buick ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overhead Valve Engine
An overhead valve engine, abbreviated (OHV) and sometimes called a pushrod engine, is a piston engine whose valves are located in the cylinder head above the combustion chamber. This contrasts with flathead (or "sidevalve") engines, where the valves were located below the combustion chamber in the engine block. Although an overhead camshaft (OHC) engine also has overhead valves, the common usage of the term "overhead valve engine" is limited to engines where the camshaft is located in the engine block. In these traditional OHV engines, the motion of the camshaft is transferred using pushrods (hence the term "pushrod engine") and rocker arms to operate the valves at the top of the engine. However, some designs have the camshaft in the cylinder head but still sit below or alongside the valves (the Ford CVH and Opel CIH are good examples), so they can essentially be considered overhead valve designs. Some early intake-over-exhaust engines used a hybrid design combining eleme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V8 Engine
A V8 engine is an eight- cylinder piston engine in which two banks of four cylinders share a common crankshaft and are arranged in a V configuration. Origins The first known V8 was the Antoinette, designed by Léon Levavasseur, and built in 1904 by the French Antoinette company for use in speedboat racing, cars, and later, airplanes. Also in 1904, V8 engines began small-scale production by Renault and Buchet for use in race cars. Design V-angle Most engines use a V-angle (the angle between the two banks of cylinders) of 90 degrees. This angle results in good engine balance, which results in low vibrations. However, the downside is the greater width of the engine compared to those that use a smaller V-angle. V8 engines with a 60-degree V-angle were used in the 1996–1999 Ford Taurus SHO, the 2005–2011 Volvo XC90, and the 2006–2009 Volvo S80. The Ford engine used a 60-degree V-angle because it was based on a V6 engine with a 60-degree V-angle. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naturally-aspirated
A naturally aspirated engine, also known as a normally aspirated engine, and abbreviated to N/A or NA, is an internal combustion engine in which air intake depends solely on atmospheric pressure and does not have forced induction through a turbocharger or a supercharger. Description In a naturally aspirated engine, air for combustion ( Diesel cycle in a diesel engine or specific types of Otto cycle in petrol engines, namely petrol direct injection) or an air/fuel mixture (traditional Otto cycle petrol engines), is drawn into the engine's cylinders by atmospheric pressure acting against a partial vacuum that occurs as the piston travels downwards toward bottom dead centre during the intake stroke. Owing to innate restriction in the engine's inlet tract, which includes the intake manifold, a small pressure drop occurs as air is drawn in, resulting in a volumetric efficiency of less than 100 percent—and a less than complete air charge in the cylinder. The density of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manual Transmission
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canadian English, Canada, British English, the United Kingdom and American English, the United States), or stick shift (in the United States), is a multi-speed motor vehicle Transmission (mechanical device), 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 ...

Hewland
Hewland is a British engineering company, founded in 1957 by Mike Hewland, which specialises in racing-car gearboxes. Hewland currently employ 130 people at their Maidenhead facility and have diversified into a variety of markets being particularly successful in electric vehicle transmission supply. Hewland are currently supplying into Formula 1, Formula E, DTM, LMP, Rallycross, Prototype and GT Sportscar. At the beginning of 2021, Hewland was acquired by Indian Hero Motors Company. History Mike Hewland ran a small engineering business at Maidenhead in the UK with the speciality in gear cutting. In 1959, Bob Gibson-Jarvie, the Chief Mechanic of UDT Laystall racing team running Cooper F2 cars, sought help from Hewland as gearbox troubles were experienced. The result of this request came out as six successful gearboxes being designed and built in 1959, and Hewland was in the gearbox business. The first transaxle product, the Hewland Mk.I of 1960, was a minor modification of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sequential Gearbox
A sequential manual transmission, also known as a sequential gearbox or sequential transmission, is a type of non-synchronous manual transmission used mostly in motorcycles and racing cars. It produces faster shift times than traditional synchronized manual transmissions, and restricts the driver to selecting either the next or previous gear, in a successive order. Design A sequential manual transmission is unsynchronized, and allows the driver to select either the next gear (e.g. shifting from first gear to second gear) or the previous gear (e.g., shifting from third gear to second gear), operated either via electronic paddle-shifters mounted behind the steering wheel or with a sequential shifter. This restriction avoids accidentally selecting the wrong gear; however, it also prevents the driver from deliberately "skipping" gears. The use of dog clutches (rather than synchromesh) results in faster shift speeds than a conventional manual transmission. On a sequential manu ...
