BRM P261
The BRM P261, also known as the BRM P61 Mark II, is a Formula One motor racing car, designed and built by the British Racing Motors team in Bourne, Lincolnshire, Bourne, Lincolnshire, England. The BRM P261 was introduced for the 1964 Formula One season, and its design was an evolution of Tony Rudd's one-off BRM P61 car of . The P261 had a relatively long racing career; variants of the car were still being entered for Formula One World Championship Grands Prix as late as . During the course of their front-line career, BRM P261s won six World Championship races, in the hands of works drivers Graham Hill and Jackie Stewart, and finished second in both the Drivers' and Constructors' Championship standings in 1964 and . Stewart, Hill and Richard Attwood also used works P261s to compete in the Tasman Series in 1966. The BRMs dominated, with Stewart winning four, Hill two, and Attwood one of the 1966 Tasman Series' eight races.''New Zealand Motor Racing'' Stewart also won the title. The wo ...

BRM P261 At Silverstone
British Racing Motors (BRM) was a British Formula One motor racing team. Founded in 1945 and based in the market town of Bourne, Lincolnshire, Bourne in Lincolnshire, it participated from 1951 to 1977, competing in 197 Grand Prix motor racing, grands prix and winning seventeen. BRM won the constructors' title in 1962 when its driver Graham Hill became world champion. In 1963, 1964, 1965 and 1971, BRM came second in the constructors' competition. History BRM was founded just after the World War II, Second World War by Raymond Mays, who had built several Hillclimbing, hillclimb and road racing cars under the English Racing Automobiles, ERA brand before the war, and Peter Berthon, a long-time associate. Mays' pre-war successes (and access to pre-war Mercedes-Benz and Auto Union design documents) inspired him to build an all-British grand prix car for the post-war era as a national prestige project, with financial and industrial backing from the British motor industry and its su ...

Chris Irwin
Christopher Frank Stuart Irwin (born 27 June 1942 in Wandsworth, London) is a British former racing driver. He participated in 10 Formula One World Championship Grands Prix, debuting on 16 July 1966. He scored two championship points. Irwin's career was ended prematurely by an accident he sustained when driving a Ford P68 sports prototype during practice for the 1968 1000km Nürburgring endurance race. He lost control of the notoriously twitchy car at the Flugplatz, the P68 flipping end over end after landing on its tail following a jump. He suffered severe head injuries but eventually recovered. However, it prevented him from racing again. Irwin is still alive and reasonably well, but his whereabouts are largely unknown as he stays out of the public eye and away from motor racing events. In 2006 it was reported that he had become re-acquainted with a racing rival from the 1960s after a chance meeting in London, and that he sometimes still suffers flashbacks to his accide ...

Dunlop Rubber
Dunlop Ltd. (formerly Dunlop Rubber) was a British multinational company involved in the manufacture of various natural rubber goods. Its business was founded in 1889 by Harvey du Cros and he involved John Boyd Dunlop who had re-invented and developed the first pneumatic tyre: he invented the first practical pneumatic tyres for his child's tricycle. It was one of the first multinationals, and under du Cros and, after him, under Eric Geddes, grew to be one of the largest British industrial companies. J. B. Dunlop had dropped any ties to it well before his name was used for any part of the business. The business and manufactory was founded in Upper Stephen Street, Dublin. A plaque marks the site, which is now part of the head office of the Irish multinational departments store brand, Dunnes Stores. Dunlop Rubber failed to adapt to evolving market conditions in the 1970s, despite having recognised by the mid-1960s the potential drop in demand as the more durable radial tyres s ...

Royal Dutch Shell
Shell plc is a British multinational oil and gas company, headquartered in London, England. Shell is a public limited company with a primary listing on the London Stock Exchange (LSE) and secondary listings on Euronext Amsterdam and the New York Stock Exchange. A core component of Big Oil, Shell is the second largest investor-owned oil and gas company in the world by revenue (after ExxonMobil), and among the world's largest companies out of any industry. Measured by both its own emissions, and the emissions of all the fossil fuels it sells, Shell was the ninth-largest corporate producer of greenhouse gas emissions in the period 1988–2015. Shell was formed in April 1907 through the merger of Royal Dutch Petroleum Company of the Netherlands and The "Shell" Transport and Trading Company of the United Kingdom. The combined company rapidly became the leading competitor of the American Standard Oil and by 1920 Shell was the largest producer of oil in the world. Shell first ente ...

Manual Gearbox
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 ...

RMR Layout
In automotive design, an RMR, or rear mid-engine, rear-wheel-drive layout is one in which the rear wheels are driven by an engine placed with its center of gravity in front of the rear axle, and thus right behind the passenger compartment. Nowadays more frequently called 'RMR', to acknowledge that certain sporty or performance focused front-engined cars are also "mid-engined", by having the main engine mass behind the front axle, RMR layout cars were previously (until ca. the 1990) just called MR, or mid-engine, rear-wheel-drive layout), because the nuance between distinctly front-engined vs. front ''mid-engined'' cars often remained undiscussed. In contrast to the fully rear-engine, rear-wheel-drive layout, the center of mass of the engine is in front of the rear axle. This layout is typically chosen for its favorable weight distribution. Placing the car's heaviest component within the wheelbase minimizes its rotational inertia around the vertical axis, facilitating turn-in or ...

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 Gasoline direct injection, petrol direct injection) or an air/fuel mixture (traditional Otto cycle petrol engines), is drawn into the engine's cylinder (engine), cylinders by atmospheric pressure acting against a Vacuum, partial vacuum that occurs as the piston travels downwards toward Dead centre (engineering), bottom dead centre during the intake stroke (engine), stroke. Owing to innate restriction in the engine's inlet tract, which includes the Inlet manifold, intake manifold, a small pressure drop occurs as air is drawn in, resulting in a volumetric effici ...

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] |
Coilover
A coilover is an automobile suspension (vehicle), suspension device. The name coilover is an abbreviation of "coil over shock absorber". Description Coilovers are found on many vehicles, from Radio-controlled car, RC cars to normal passenger cars, race cars and Four-wheel drive, 4x4 vehicles. They are sometimes used as a factory suspension option on new cars. Coilovers are used in double wishbone suspension systems, and are often a component of MacPherson struts. Two of the main types of coilovers are full coilovers and slip-on coilovers. Full coilovers are matched up with a shock absorber from the factory, while with slip-on coilovers, the dampers and springs are bought separately and then assembled. There are a large number of companies who make Aftermarket (merchandise), aftermarket coilovers for vehicles, many of which allow the customer to adjust various settings such as ride height and Damping ratio, damping. Camber angle, Camber and caster angles can also be adjusted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shock Absorber
A shock absorber or damper is a mechanical or hydraulics, hydraulic device designed to absorb and Damping ratio, damp shock (mechanics), shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically thermal energy, heat) which is then dissipated. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction). Description Pneumatic and hydraulic shock absorbers are used in conjunction with cushions and springs. An automobile shock absorber contains spring-loaded check valves and orifices to control the flow of oil through an internal piston (see below). One design consideration, when designing or choosing a shock absorber, is where that energy will go. In most shock absorbers, energy is converted to heat inside the viscous fluid. In hydraulic cylinders, the hydraulic fluid heats up, while in Pneumatic cylinder, air cylinders, the hot air is usually exhausted to the atmosphere. In other types of ...

Coil Spring
A tension coil spring A coil spring is a mechanical device that typically is used to store energy and subsequently release it, to absorb shock, or to maintain a force between contacting surfaces. It is made of an elastic material formed into the shape of a helix that returns to its natural length when unloaded. Under tension or compression, the material (wire) of a coil spring undergoes torsion. The spring characteristics therefore depend on the shear modulus. A coil spring may also be used as a torsion spring: in this case the spring as a whole is subjected to torsion about its helical axis. The material of the spring is thereby subjected to a bending moment, either reducing or increasing the helical radius. In this mode, it is the Young's modulus of the material that determines the spring characteristics. Spring rate A selection of conical coil springs Spring rate is the measurement of how much load (in pounds) a coil spring can hold until it compresses . The spring r ...

Double Wishbone Suspension
A double wishbone suspension is an independent suspension design for automobiles using two (occasionally parallel) wishbone-shaped arms to locate the wheel. Each wishbone or arm has two mounting points to the chassis and one joint at the knuckle. The shock absorber and coil spring mount to the wishbones to control vertical movement. Double wishbone designs allow the engineer to carefully control the motion of the wheel throughout suspension travel, controlling such parameters as camber angle, caster angle, toe pattern, roll center height, scrub radius, scuff ( mechanical abrasion), and more. Implementation The double-wishbone suspension can also be referred to as "double A-arms", though the arms themselves can be A-shaped or L-shaped. A single wishbone or A-arm can also be used in various other suspension types, such as variations of the MacPherson strut. The upper arm is usually shorter to induce negative camber as the suspension jounces (rises), and often this arrangement ...
