Bentley Blower No.1
Bentley Blower No.1 is a racing car developed from the Bentley 4½ Litre by Sir Henry "Tim" Birkin to win the Le Mans twenty-four-hour race. The car was developed into its current form for racing at Brooklands. In June 2012, the car was sold by Bonhams for £5,042,000 at the Goodwood Festival of Speed. Background In 1921 Sir Henry "Tim" Birkin turned to motor racing, competing in a few races at Brooklands. Business and family pressure then forced him to retire from the tracks until 1927 when he entered a three-litre Bentley for a six-hour race. For 1928 he acquired a 4½ litre car and after some good results decided to return to motor racing, very much against his family's wishes. Soon Birkin was one of the Bentley Boys, described as "the greatest Briton of his time" by W. O. Bentley. In 1928 Birkin entered the Le Mans race again, leading the first twenty laps until a jammed wheel forced him to drop back, finishing fifth. He won the race in 1929, racing the Speed Six ...

Birkin Bentley 4½ Litre Blower
Birkin is a village and civil parish in the south-west of the Selby district of North Yorkshire, England. It is north of the River Aire, near Beal, North Yorkshire. The closest town is Knottingley, in West Yorkshire, to the south-west. The parish had a population of 146 at the 2001 census, which fell to 141 at the 2011 census. Until 1974, it was part of the West Riding district of Yorkshire. History Birkin is recorded in the Domesday Book as 'Birchinge'. This and the present name suggest that, when the village was first established, it was in an area heavily laden with birch trees. The village’s St Mary's Church, built around 1150, is a Grade I listed building. The village is also notable as the birthplace of the 19th-century political philosopher Thomas Hill Green (b. 1836.) The 2016 Tour de Yorkshire passed through Birkin in its second stage (Otley to Doncaster). Birkin has two lakes east of the village that are used for public fishing. It also has a tea room. St Ma ...

Woolf Barnato
Joel Woolf BarnatoPronounced Barnatoo – from Barnett too (27 September 1895 – 27 July 1948) was a British financier and racing driver, one of the "Bentley Boys" of the 1920s. He achieved three consecutive wins out of three entries in the 24 Hours of Le Mans race. Early life The youngest son of Fanny Bees and Barney Barnato, who had made a fortune as a "Randlord" in South African diamond and gold mining, he was a relative of the Joel family of entrepreneurs. He was born at Spencer House, 27 St James's Place, London. He had a sister, Leah Primrose (died 1933) and a brother, Isaac "Jack" Henry (died 1918 of bronchial pneumonia). The family divided their time between London, Brighton, Colwyn Bay and South Africa. In 1897, when Woolf was two years old, his father died near Madeira during a sea crossing from South Africa to London. The official verdict was suicide ("death by drowning while temporarily insane"). Woolf inherited his father's fortune, but with the monies place ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weymann Fabric Bodies
Weymann Fabric Bodies is a patented design system for fuselages for aircraft and superlight coachwork for motor vehicles. The system used a patent-jointed wood frame covered in fabric. It was popular on cars from the 1920s until the early 1930s as it reduced the usual squeaks and rattles of coachbuilt bodies by its use of flexible joints between body timbers.A-Z of British Coachbuilders. Nick Walker. Bay View Books 1997. The system when used on cars provided quieter travel, and improved performance because of the body's light weight; but gave little protection in the event of a serious accident, and without care (the materials being prone to rot), a potentially short life. Fabric provided a matt surface and the framework sharp corners. Later supporting metal corner-inserts were employed to smooth corners and the fabric could be finished with layer upon layer of hand-sanded paint, called ''Tôle Souple'', giving the impression of polished metal panelling. Introduced to the market ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carburetor
A carburetor (also spelled carburettor) is a device used by an internal combustion engine to control and mix air and fuel entering the engine. The primary method of adding fuel to the intake air is through the venturi tube in the main metering circuit, however various other components are also used to provide extra fuel or air in specific circumstances. Since the 1990s, carburetors have been largely replaced by fuel injection for cars and trucks, however carburetors are still used by some small engines (e.g. lawnmowers, generators and concrete mixers) and motorcycles. Diesel engines have always used fuel injection instead of carburetors. Etymology The name "carburetor" is derived from the verb ''carburet'', which means "to combine with carbon," or in particular, "to enrich a gas by combining it with carbon or hydrocarbons." Thus a carburetor mixes intake air with hydrocarbon-based fuel, such as petrol or autogas (LPG). The name is spelled "carburetor" in American English ...

Understeer And Oversteer
Understeer and oversteer are vehicle dynamics terms used to describe the sensitivity of a vehicle to steering. Oversteer is what occurs when a car turns (steers) by more than the amount commanded by the driver. Conversely, understeer is what occurs when a car steers less than the amount commanded by the driver. Automotive engineers define understeer and oversteer based on changes in steering angle associated with changes in lateral acceleration over a sequence of steady-state circular turning tests. Car and motorsport enthusiasts often use the terminology more generally in magazines and blogs to describe vehicle response to steering in a variety of maneuvers. Vehicle dynamics terminology Standard terminology used to describe understeer and oversteer are defined by the Society of Automotive Engineers (SAE) in document J670SAE International Surface Vehicle Recommended Practice, "Vehicle Dynamics Terminology", SAE Standard J670, Rev. 2008-01-24 and by the International Organization ...

Crankshaft
A crankshaft is a mechanical component used in a piston engine to convert the reciprocating motion into rotational motion. The crankshaft is a rotating shaft containing one or more crankpins, that are driven by the pistons via the connecting rods. The crankpins are also called ''rod bearing journals'', and they rotate within the "big end" of the connecting rods. Most modern crankshafts are located in the engine block. They are made from steel or cast iron, using either a forging, casting or machining process. Design The crankshaft located within the engine block, held in place via main bearings which allow the crankshaft to rotate within the block. The up-down motion of each piston is transferred to the crankshaft via connecting rods. A flywheel is often attached to one end of the crankshaft, in order to smoothen the power delivery and reduce vibration. A crankshaft is subjected to enormous stresses, in some cases more than per cylinder. Crankshafts for single-cylin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camshaft
A camshaft is a shaft that contains a row of pointed cams, in order to convert rotational motion to reciprocating motion. Camshafts are used in piston engines (to operate the intake and exhaust valves), mechanically controlled ignition systems and early electric motor speed controllers. Camshafts in piston engines are usually made from steel or cast iron, and the shape of the cams greatly affects the engine's characteristics. History Trip hammers are one of the early uses of a form of cam to convert rotating motion, e.g. from a waterwheel, into the reciprocating motion of a hammer used in forging or to pound grain. Evidence for these exists back to the Han Dynasty in China, and they were widespread by the medieval period. The camshaft was described in 1206 by engineer Al-Jazari. He employed it as part of his automata, water-raising machines, and water clocks such as the castle clock. Once the rotative version of the steam engine was developed in the late 18th century, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hertfordshire
Hertfordshire ( or ; often abbreviated Herts) is one of the home counties in southern England. It borders Bedfordshire and Cambridgeshire to the north, Essex to the east, Greater London to the south, and Buckinghamshire to the west. For government statistical purposes, it forms part of the East of England region. Hertfordshire covers . It derives its name – via the name of the county town of Hertford – from a hart (stag) and a ford, as represented on the county's coat of arms and on the flag. Hertfordshire County Council is based in Hertford, once the main market town and the current county town. The largest settlement is Watford. Since 1903 Letchworth has served as the prototype garden city; Stevenage became the first town to expand under post-war Britain's New Towns Act of 1946. In 2013 Hertfordshire had a population of about 1,140,700, with Hemel Hempstead, Stevenage, Watford and St Albans (the county's only ''city'') each having between 50,000 and 100,000 r ...

Welwyn Garden City
Welwyn Garden City ( ) is a town in Hertfordshire, England, north of London. It was the second garden city in England (founded 1920) and one of the first new towns (designated 1948). It is unique in being both a garden city and a new town and exemplifies the physical, social and cultural planning ideals of the periods in which it was built. History Welwyn Garden City was founded by Sir Ebenezer Howard in 1920 following his previous experiment in Letchworth Garden City. Howard had called for the creation of planned towns that were to combine the benefits of the city and the countryside and to avoid the disadvantages of both. It was designed to be 'The Perfect Town'. The Garden Cities and Town Planning Association had defined a garden city as "a town designed for healthy living and industry of a size that makes possible a full measure of social life but not larger, surrounded by a rural belt; the whole of the land being in public ownership, or held in trust for the community ...

Roots-type Supercharger
The Roots-type blower is a positive displacement lobe pump which operates by pumping a fluid with a pair of meshing lobes resembling a set of stretched gears. Fluid is trapped in pockets surrounding the lobes and carried from the intake side to the exhaust. The most common application of the Roots-type blower has been the induction device on two-stroke diesel engines, such as those produced by Detroit Diesel and Electro-Motive Diesel. Roots-type blowers are also used to supercharge four-stroke Otto cycle engines, with the blower being driven from the engine's crankshaft via a toothed or V-belt, a roller chain or a gear train. The Roots-type blower is named after American inventors and brothers Philander and Francis Marion Roots, founders of the Roots Blower Company of Connersville, Indiana USA, who patented the basic design in 1860 as an air pump for use in blast furnaces and other industrial applications. In 1900, Gottlieb Daimler included a Roots-style blower in a pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
