Jaguar D-Type
The Jaguar D-Type is a sports racing car that was produced by Jaguar Cars Ltd. between 1954 and 1957. Designed specifically to win the Le Mans 24-hour race, it shared the straight-6 XK engine and many mechanical components with its C-Type predecessor. Its structure, however, was radically different, with innovative monocoque construction and slippery aerodynamics that integrated aviation technology, including in some examples a distinctive vertical stabilizer. Engine displacement began at 3.4 litres, was enlarged to 3.8 L in 1957, and reduced to 3.0 L in 1958 when Le Mans rules limited engines for sports racing cars to that maximum. D-Types won Le Mans in 1955, 1956 and 1957. After Jaguar temporarily retired from racing as a factory team, the company offered the remaining unfinished D-Types as street-legal XKSS versions, whose perfunctory road-going equipment made them eligible for production sports car races in America. In 1957 25 of these cars were in various stages ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Duncan Hamilton (racing Driver)
James Duncan Hamilton (30 April 1920 in Cork, County Cork, Ireland – 13 May 1994 in Sherborne, Dorset, England) was a British racing driver. He was famed for his colourful and extrovert personality, which often overshadowed his genuine talent. After fighting in, and surviving the Second World War, he took up motorsport. Although adept in single-seaters, sportscars was where he enjoyed most success, winning the 1953 24 Heures du Mans, two Coupe de Paris events, and the 12 heures internationals Reims race in 1956. He retired in 1958 and ran a garage in Bagshot, Surrey for many years. He died from lung cancer in 1994. Early years Born in County Cork, Hamilton was brought up in relative obscurity. Prior to his 20th birthday, Europe was already embroiled in the Second World War. As a result, he would spend the war years as part of the Fleet Air Arm flying Lysanders. After the war ended, he opened a car garage. During the years between the war ending and the start of the 1950s, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1954 24 Hours Of Le Mans
The 1954 24 Hours of Le Mans was a 22nd race for Sports Cars, and took place on 12 and 13 June 1954, at the Circuit de la Sarthe, Le Mans, France. It was also the fourth race of the 1954 World Sportscar Championship. The race was won by José Froilán González and Maurice Trintignant driving a Ferrari 375 Plus. People viewed this race as a battle between brute force and science (per the July 1954 "Motor Sport" article Clarke 1997, p.99: Motor Sport July 1954). In the high technology corner, with its sleek, aerodynamic bodywork was the new 3.4-litre Jaguar D-Type, and in the other corner was Ferrari's formidable 5.0-litre V12 375 Plus. Ranged in between was everyone else. The race was heavily affected by poor weather throughout and was a thriller right to the end, producing the closest finish for the race since 1933: less than 5km (half a lap).Spurring 2011, p.183 Regulations The ACO again extended the replenishment window (last updated in 1952) of fuel, oil and water from 28 ...

Lofty England
Frank Raymond Wilton "Lofty" England (24 August 1911, Finchley, Middlesex – 30 May 1995, Austria) was an engineer and motor company manager from Britain. He rose to fame as the manager of the Jaguar Cars sports car racing team in the 1950s, during which time Jaguar cars won the prestigious 24 Hours of Le Mans race on five occasions. After the company's withdrawal from racing England moved into the mainstream management of Jaguar Cars, later succeeding Sir William Lyons as its chairman and Chief Executive, before retiring in 1974. Early life Frank England was born in Finchley, Middlesex, and found an aptitude and interest in motor engineering during his schooling at Christ's College.Wood, J. 1995. ''Obituaries: Lofty England''. The Independent. 9 June 1995. At the age of 14 the England family moved to Edgware. Here the young Frank was able to watch Bentley chassis, built in nearby Cricklewood, being tested along the long, straight A5 road, formerly part of the Roman Road of Watl ...

Jaguar XKD403
The jaguar (''Panthera onca'') is a large cat species and the only living member of the genus ''Panthera'' native to the Americas. With a body length of up to and a weight of up to , it is the largest cat species in the Americas and the third largest in the world. Its distinctively marked coat features pale yellow to tan colored fur covered by spots that transition to rosettes on the sides, although a melanistic black coat appears in some individuals. The jaguar's powerful bite allows it to pierce the carapaces of turtles and tortoises, and to employ an unusual killing method: it bites directly through the skull of mammalian prey between the ears to deliver a fatal blow to the brain. The modern jaguar's ancestors probably entered the Americas from Eurasia during the Early Pleistocene via the land bridge that once spanned the Bering Strait. Today, the jaguar's range extends from core Southwestern United States across Mexico and much of Central America, the Amazon rainforest ...

Cylinder Head
In an internal combustion engine, the cylinder head (often abbreviated to simply "head") sits above the cylinders and forms the roof of the combustion chamber. In sidevalve engines, the head is a simple sheet of metal; whereas in more modern overhead valve and overhead camshaft engines, the cylinder head is a more complicated block often containing inlet and exhaust passages, coolant passages, valves, camshafts, spark plugs and fuel injectors. Most straight engines have a single cylinder head shared by all of the cylinders and most V engines have two cylinder heads (one per bank of cylinders). Design A summary of engine designs is shown below, in chronological order for automobile usage. Sidevalve engines In a flathead (''sidevalve'') engine, all of the valvetrain components are contained within the block, therefore the head is usually a simple sheet of metal bolted to the top of the engine block. Sidevalve engines were once universal in automobiles but are now lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poppet Valve
A poppet valve (also called mushroom valve) is a valve typically used to control the timing and quantity of gas or vapor flow into an engine. It consists of a hole or open-ended chamber, usually round or oval in cross-section, and a plug, usually a disk shape on the end of a shaft known as a valve stem. The working end of this plug, the valve face, is typically ground at a 45° bevel to seal against a corresponding valve seat ground into the rim of the chamber being sealed. The shaft travels through a valve guide to maintain its alignment. A pressure differential on either side of the valve can assist or impair its performance. In exhaust applications higher pressure against the valve helps to seal it, and in intake applications lower pressure helps open it. The poppet valve was invented in 1833 by American E.A.G. Young of the New Castle and Frenchtown Turnpike and Railroad Company, Newcastle and Frenchtown Railroad. Young had patented his idea, but the 1836 U.S. Patent Offic ...

Disc Brakes
A disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a disc or a "rotor" to create friction. This action slows the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary. The energy of motion is converted into waste heat which must be dispersed. Hydraulically actuated disc brakes are the most commonly used form of brake for motor vehicles, but the principles of a disc brake are applicable to almost any rotating shaft. The components include the disc, master cylinder, and caliper (which contains a cylinder and two brake pads) on both sides of the disc. Design The development of disc-type brakes began in England in the 1890s. In 1902, the Lanchester Motor Company designed brakes that looked and operated in a similar way to a modern disc-brake system even though the disc was thin and a cable activated the brake pad. Other designs were not practical or widely available in cars for another 6 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Mulsanne Straight
The Mulsanne Straight (''Ligne Droite des Hunaudières'' in French) is the name used in English for a formerly long straight of the Circuit de la Sarthe around which the 24 Hours of Le Mans auto race takes place. Since 1990, the straight is interrupted by two chicanes, with the last section (that includes a slight right turn known as the "Kink") leading to a sharp corner near the village of Mulsanne. French name When races are not taking place, the Mulsanne Straight is part of the national road system of France. It is called the ''Ligne Droite des Hunaudières'', a part of the ''route départementale'' RD 338 (formerly Route Nationale RN 138) in the Sarthe department. The ''Hunaudières'' leads to the village of Mulsanne, its English namesake (though the French ''Route de Mulsanne'' is the name for the road between Mulsanne and Arnage, with the ''Indianapolis'' corner in between). History During the 1911 Grand Prix season, the Grand Prix de France used an early version of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dry Sump
A dry-sump system is a method to manage the lubricating motor oil in four-stroke and large two-stroke piston driven internal combustion engines. The dry-sump system uses two or more oil pumps and a separate oil reservoir, as opposed to a conventional wet-sump system, which uses only the main sump (U.S.: oil pan) below the engine and a single pump. A dry-sump engine requires a pressure relief valve to regulate negative pressure inside the engine, so internal seals are not inverted. Dry-sumps are common on larger diesel engines such as those used in ships, as well as gasoline engines used in racing cars, aerobatic aircraft, high-performance personal watercraft and motorcycles. Dry sump lubrication may be chosen for these applications due to increased reliability, oil capacity, reduction of oil starvation under high g-loads and/or other technical or performance reasons. Dry sump systems may not be suitable for all applications due to increased cost, complexity, and/or bulk, am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
