Norton RCW588
The Norton RCW588 is a Works Racing motorcycle, produced for the 1988 to 1994 racing seasons, initially with an air-cooled version of the road-going twin-rotor Wankel engine used in the Classic soon followed by watercooled versions from 1989. Racing started in late 1987 with employee Malcolm Heath as development rider on a limited budget, then with a six-man team from 1989 including riders Trevor Nation and Simon Buckmaster. With major sponsor John Player & Sons, the Norton Rotary achieved significant racing success with riders Steve Spray, Robert Dunlop, and Ron Haslam, together with stand-in riders Andy McGladdery and Terry Rymer. Steve Hislop achieved a win at the 1992 Senior TT race, the first time Norton had won the class since 1961, and Ian Simpson won the 1994 British Superbike Championship. The unique Wankel engine configuration measured at a capacity of 588 cc was accepted by the FIM in 1990, allowing the Norton to enter the 500 cc Grand Prix premier racing cl ...

Norton Commander (motorcycle)
The Commander was a Norton motorcycle with a Wankel rotary engine. The first Norton Wankel motorcycle was the 1987 Classic using an air-cooled engine, built as a special edition of just 100 machines. It was followed by the air-cooled Interpol 2 model. The Commander was a liquid-cooled successor to the Interpol 2, liquid cooling being adopted for greater power and reliability. The Commander's final-drive chain was protected by a full enclosure. Some cycle parts (such as wheels, forks, switchgear, clocks & brakes) were bought-in Yamaha items from the XJ900. Two types of Commander were built. The P52 was a single-seat model equipped for police use. The second was the dual-seat P53 civilian tourer. Both the P52 and P53 had panniers integral with their fibreglass bodywork. The P53 bodywork was later revised to have detachable K2 panniers.

Duckham's Oils
Alexander Duckham (11 March 1877 – 1 February 1945) was an English chemist and businessman, best known for the development of machine lubricants. The son of an engineer, after university he specialised in lubrication, working briefly for Fleming's Oil Company before founding his own company, Alexander Duckham & Co, in Millwall in 1899. By the outbreak of World War I, he was an authority on technological problems relating to lubrication, and the company went public in about 1920, relocating from Millwall to Hammersmith. By the time he died in 1945, Duckhams had assumed a dominant position for the supply of lubricants and corrosion inhibitors to the motor industry in Britain and other markets. A new manufacturing plant was opened in Staffordshire in 1968, and soon thereafter the company was taken over by BP. Early career Duckham was born in Blackheath, London, the eldest son of a Falmouth-born mechanical and civil engineer, Frederic Eliot Duckham (1841 - died 13 January 1918 in ...

Compression Ratio
The compression ratio is the ratio between the volume of the cylinder and combustion chamber in an internal combustion engine at their maximum and minimum values. A fundamental specification for such engines, it is measured two ways: the static compression ratio, calculated based on the relative volumes of the combustion chamber and the cylinder when the piston is at the bottom of its stroke, and the volume of the combustion chamber when the piston is at the top of its stroke. The dynamic compression ratio is a more advanced calculation which also takes into account gasses entering and exiting the cylinder during the compression phase. Effect and typical ratios A high compression ratio is desirable because it allows an engine to extract more mechanical energy from a given mass of air–fuel mixture due to its higher thermal efficiency. This occurs because internal combustion engines are heat engines, and higher compression ratios permit the same combustion temperature to ...

Venturi Effect
The Venturi effect is the reduction in fluid pressure that results when a fluid flows through a constricted section (or choke) of a pipe. The Venturi effect is named after its discoverer, the 18th century Italian physicist, Giovanni Battista Venturi. Background In inviscid fluid dynamics, an incompressible fluid's velocity must ''increase'' as it passes through a constriction in accord with the principle of mass continuity, while its static pressure must ''decrease'' in accord with the principle of conservation of mechanical energy (Bernoulli's principle). Thus, any gain in kinetic energy a fluid may attain by its increased velocity through a constriction is balanced by a drop in pressure. By measuring pressure, the flow rate can be determined, as in various flow measurement devices such as Venturi meters, Venturi nozzles and orifice plates. Referring to the adjacent diagram, using Bernoulli's equation in the special case of steady, incompressible, inviscid flows (such as t ...

Motorcycle Fork
A motorcycle fork connects a motorcycle's front wheel and axle to its frame, typically via a yoke, also known as a triple clamp, which consists of an upper yoke joined to a lower yoke via a steering stem, a shaft that runs through the steering head, creating the steering axis. Most forks incorporate the front suspension and front brake, and allow the front wheel to rotate about the steering axis so that the bike may be steered. Most handlebars attach to the top clamp in various ways, while clip-on handlebars clamp to the fork tubes, either just above or just below the upper triple clamp. The fork and its attachment points on the frame establish the critical geometric parameters of rake and trail, which play a major role in defining how a motorcycle handles and dives during braking. While the standard telescopic fork arrangement is found with few major differences among mainstream street motorcycles since the 1970s, historically there have been many variations, including trailin ...

Monoshock
A motorcycle's suspension serves a dual purpose: contributing to the vehicle's handling and braking, and providing safety and comfort by keeping the vehicle's passengers comfortably isolated from road noise, bumps and vibrations. The typical motorcycle has a pair of fork tubes for the front suspension, and a swingarm with one or two shock absorbers for the rear suspension. Front suspension The most common form of front suspension for a modern motorcycle is the telescopic fork. Other fork designs are girder forks, suspended on sprung parallel links (not common since the 1940s) and bottom leading link designs, not common since the 1960s. Some manufacturers (e.g. Greeves) used a version of the swinging arm for front suspension on their motocross designs. A single-sided version of the idea is also used in motor scooters such as the Vespa. The hub-center steering as developed by Ascanio Rodorigo, on a concept associated to Massimo Tamburini is a complex front swingarm alternat ...

Ram-air Intake
A ram-air intake is any intake design which uses the dynamic air pressure created by vehicle motion, or ram pressure, to increase the static air pressure inside of the intake manifold on an internal combustion engine, thus allowing a greater massflow through the engine and hence increasing engine power. Design features The ram-air intake works by reducing the intake air velocity by increasing the cross-sectional area of the intake ducting. When gas velocity goes down the dynamic pressure is reduced, while the static pressure is increased. The increased static pressure in the plenum chamber has a positive effect on engine power, both because of the pressure itself and the increased air density that this higher pressure gives. Ram-air systems are used on high-performance vehicles, most often on motorcycles and performance cars. The 1990 Kawasaki Ninja ZX-11 C1 model used a ram-air intake, the very first on any production motorcycle. Ram-air was a feature on some cars in the six ...

Fin (extended Surface)
In the study of heat transfer, fins are surfaces that extend from an object to increase the rate of heat transfer to or from the environment by increasing convection. The amount of conduction, convection, or radiation of an object determines the amount of heat it transfers. Increasing the temperature gradient between the object and the environment, increasing the convection heat transfer coefficient, or increasing the surface area of the object increases the heat transfer. Sometimes it is not feasible or economical to change the first two options. Thus, adding a fin to an object, increases the surface area and can sometimes be an economical solution to heat transfer problems. One-piece finned heat sinks are produced by extrusion, casting, skiving, or milling. General case To create a tractable equation for the heat transfer of a fin, many assumptions need to be made: # Steady state # Constant material properties (independent of temperature) # No internal heat generation # On ...
