Rolls-Royce 20 hp (1905)
The Rolls-Royce 20 hp was one of four car models to be produced as a result of an agreement of 23 December 1904 between Charles Rolls and Henry Royce. Badged as a Rolls-Royce, the 20 hp was produced during 1905 and 1906 by Royce's company, Royce Ltd. at its factory in Cooke Street, Hulme, Manchester. It was sold exclusively by Rolls' motor dealership, C.S.Rolls & Co., at a price of GBP650.In chassis only form. The 20 hp was exhibited at the Paris Salon in December 1904, along with the 10 hp, 15 hp and engine for the 30 hp models. The engine was made of two separately cast two-cylinder units which were common with the two-cylinder 10 hp and six-cylinder 30 hp types sharing their bore of and stroke of . It is water-cooled and of 4118 cc capacity with overhead inlet and side exhaust valves Early cars had a high-tension ignition system using pre-charged accumulators, a trembler and a coil ignition system; on later cars this was supplement ...

Cubic Metre
The cubic metre (in Commonwealth English and international spelling as used by the International Bureau of Weights and Measures) or cubic meter (in American English) is the unit of volume in the International System of Units (SI). Its symbol is m3. Bureau International de Poids et Mesures.Derived units expressed in terms of base units". 2014. Accessed 7 August 2014. It is the volume of a cube with edges one metre in length. An alternative name, which allowed a different usage with metric prefixes, was the stère, still sometimes used for dry measure (for instance, in reference to wood). Another alternative name, no longer widely used, was the kilolitre. Conversions : A cubic metre of pure water at the temperature of maximum density (3.983 °C) and standard atmospheric pressure (101.325 kPa) has a mass of , or one tonne. At 0 °C, the freezing point of water, a cubic metre of water has slightly less mass, 999.85 kilograms. A cubic metre is sometimes abbreviated ...

Side Valve
A flathead engine, also known as a sidevalve engine''American Rodder'', 6/94, pp.45 & 93. or valve-in-block engine, is an internal combustion engine with its poppet valves contained within the engine block, instead of in the cylinder head, as in an overhead valve engine. Flatheads were widely used internationally by automobile manufacturers from the late 1890s until the mid-1960s but were replaced by more efficient overhead valve and overhead camshaft engines. They are currently experiencing a revival in low-revving aero-engines such as the D-Motor. The side-valve design The valve gear comprises a camshaft sited low in the cylinder block which operates the poppet valves via tappets and short pushrods (or sometimes with no pushrods at all). The flathead system obviates the need for further valvetrain components such as lengthy pushrods, rocker arms, overhead valves or overhead camshafts. The sidevalves are typically adjacent, sited on one side of the cylinder(s), though s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cars Introduced In 1905
A car, or an automobile, is a motor vehicle with wheels. Most definitions of cars state that they run primarily on roads, seat one to eight people, have four wheels, and mainly transport people rather than cargo. There are around one billion cars in use worldwide. The French inventor Nicolas-Joseph Cugnot built the first steam-powered road vehicle in 1769, while the Swiss inventor François Isaac de Rivaz designed and constructed the first internal combustion-powered automobile in 1808. The modern car—a practical, marketable automobile for everyday use—was invented in 1886, when the German inventor Carl Benz patented his Benz Patent-Motorwagen. Commercial cars became widely available during the 20th century. The 1901 Oldsmobile Curved Dash and the 1908 Ford Model T, both American cars, are widely considered the first mass-produced and mass-affordable cars, respectively. Cars were rapidly adopted in the US, where they replaced horse-drawn carriages. In Europe and other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Artillery Wheel
The artillery wheel was a nineteenth-century and early-twentieth-century style of wagon, gun carriage, and automobile wheel. Rather than having its spokes mortised into a wooden nave (hub), it has them fitted together in a keystone fashion with miter joints, bolted into a two-piece metal nave. Its tyre is shrunk onto the rim in the usual way, but it may also be bolted on for security. The design evolved over the nineteenth and early twentieth century, and was ultimately imitated in drawn steel for auto wheels, which sometimes show little immediate resemblance to most of their design ancestry. Wood artillery wheels Wheels with wood spokes fitted together in a keystone fashion with miter joints, bolted into a two-piece metal Nave (wheel hub), nave, were called "wedge wheels" by Walter Hancock who described them in 1834, as he used them on his steam-powered road vehicles. In response to Hancock's description, John Robison said he had wheels of the same description built in 1811 f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isle Of Man
The Isle of Man ( , also ), or Mann ( ), is a self-governing British Crown Dependency in the Irish Sea, between Great Britain and Ireland. As head of state, Charles III holds the title Lord of Mann and is represented by a Lieutenant Governor. The government of the United Kingdom is responsible for the Isle of Man's military defence and represents it abroad, but the Isle of Man still has a separate international identity. Humans have lived on the island since before 6500 BC. Gaelic cultural influence began in the 5th century AD, when Irish missionaries following the teaching of St Patrick began settling the island, and the Manx language, a branch of the Goidelic languages, emerged. In 627, King Edwin of Northumbria conquered the Isle of Man along with most of Mercia. In the 9th century, Norsemen established the thalassocratic Kingdom of the Isles, which included the Hebrides and the Northern Isles, along with the Isle of Man as the southernmost island.

Overdrive (mechanics)
Overdrive is the operation of an automobile cruising at sustained speed with reduced engine speed (rpm), leading to better fuel consumption, lower noise, and lower wear. The term is ambiguous. The most fundamental meaning is that of an overall gear ratio between engine and wheels, such that the car is ''over-geared'', and cannot reach its potential top speed, i.e. the car could travel faster if it were in a lower gear, with the engine turning at higher RPM. The power produced by an engine increases with the engine's RPM to a maximum, then falls away. The point of maximum power is somewhat lower than the absolute maximum engine speed to which it is limited, the "redline". A car's speed is limited by the power required to drive it against air resistance, which increases with speed. At the maximum possible speed, the engine is running at its point of maximum power, or ''power peak'', and the car is traveling at the speed where air resistance equals that maximum power. There ...

Cone Clutch
A cone clutch serves the same purpose as a disk or plate clutch; however, instead of mating two spinning disks, the cone clutch uses two conical surfaces to transmit torque by friction. The cone clutch transfers a higher torque than plate or disk clutches of the same size due to the wedging action and increased surface area. Cone clutches are generally now only used in low-peripheral-speed applications, although they were once common in automobiles and other internal combustion engine transmissions. They are usually now confined to very specialist transmissions used in racing, rallying, or extreme off-road vehicles, although they are common in power boats, dredge pumps and other ship-drive lines. This is because the clutch does not have to be pushed in all the way, which allows the gears to be changed more quickly. Small cone clutches are used in synchronizer mechanisms in manual transmissions and some limited-slip differential A limited-slip differential (LSD) is a type of ...

Governor (device)
A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow of steam. History Centrifugal governors were used to regulate the distance and pressure between millstones in windmills since the 17th century. Early steam engines employed a purely reciprocating motion, and were used for pumping water – an application that could tolerate variations in the working speed. It was not until the Scottish engineer James Watt introduced the ''rotative'' steam engine, for driving factory machinery, that a constant operating speed became necessary. Between the years 1775 and 1800, Watt, in partnership with industrialist Matthew Boulton, produced so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbide Lamp
A carbide lamp or acetylene gas lamp is a simple lamp that produces and burns acetylene (C2H2), which is created by the reaction of calcium carbide (CaC2) with water (H2O). Acetylene gas lamps were used to illuminate buildings, as lighthouse beacons, and as headlights on motor-cars and bicycles. Portable acetylene gas lamps, worn on the hat or carried by hand, were widely used in mining in the early twentieth century. They are still employed by Caving, cavers, hunters, and cataphiles. History In 1892, Thomas Willson discovered an economically efficient process for creating calcium carbide in an electric arc furnace from a mixture of Lime (material), lime and Coke (fuel), coke. The arc furnace provides the high temperature required to drive the reaction. Manufacture of calcium carbide was an important part of the industrial revolution in chemistry, and was made possible in the United States as a result of massive amounts of inexpensive hydroelectric power produced at Niagara Fal ...

Ignition Magneto
An ignition magneto (also called a high-tension magneto) is an older type of ignition system used in spark-ignition engines (such as petrol engines). It uses a magneto and a transformer to make pulses of high voltage for the spark plugs. The older term "high-tension" means "high-voltage". Design A simple magneto (an electrical generator using permanent magnets) is able to produce relatively low voltage electricity, however it is unable to produce the high voltages required by a spark plug as used in most modern engines (aside from diesel engines). An ''ignition magneto'' also includes an electrical transformer, which converts the electricity to a higher voltage (with the trade-off being a corresponding reduction in the output electric current, current). As the points begin to open, point spacing is initially such that the voltage across the primary coil would arc across the points. A capacitor is placed across the points which absorbs the energy stored in the leakage inductanc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trembler Coil
A trembler coil, buzz coil or vibrator coil is a type of high-voltage ignition coil used in the ignition system of early automobiles, most notably the Benz Patent-Motorwagen and the Ford Model T. Its distinguishing feature is a vibrating magnetically-activated electrical contact, contact called a ''trembler'' or ''Induction coil#The interrupter, interrupter'', which breaks the primary current, generating multiple sparks during each cylinder's power stroke. Trembler coils were first used on the 1886 Benz Patent-Motorwagen, Benz automobile, and were used on the Model T until 1927. Operation The trembler coil was a device called a Ruhmkorff or induction coil, widely used in the 19th century. It combines two magnetic devices on the same iron-cored solenoid. The first is a transformer, used to transform low voltage electricity to a high voltage, suitable for an engine's spark plug. Two coils of wire are wound around an magnetic core, iron core. The ''primary winding'' carries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
