Flat-twelve Engine
A flat-twelve engine, also known as a horizontally opposed-twelve, is a twelve-cylinder piston engine with six cylinders on each side of a central crankshaft. Flat-twelve engines are less common than V12 engines, but they have been used in various racing cars during the 1960s and 1970s, and in mid-engined Ferrari road cars from 1973 to 1996. Design Unlike most flat-twin, flat-four, and flat-six engines, flat-twelve engines typically use the crankshaft configuration of a 180° V engine. Instead of the boxer engine design of each piston having its own crankpin, flat-twelve engines have each pair of pistons sharing a crankpin, and thus are flat, but not true boxers. Compared with a V12 engine, a flat-twelve has a lower center of gravity, but because a flat-twelve is wider they are rarely used in front-engined cars. Racing cars Formula One The first known flat-twelve engine was built by Porsche in 1947 for the abandoned Cisitalia Grand Prix racing car. The engine, known a ...

Ferrari Testarossa Motor
Ferrari S.p.A. (; ) is an Italian luxury sports car manufacturer based in Maranello. Founded in 1939 by Enzo Ferrari (1898–1988), the company built its first car in 1940, adopted its current name in 1945, and began to produce its current line of road cars in 1947. Ferrari became a public company in 1960, and from 1963 to 2014 it was a subsidiary of Fiat S.p.A. It was spun off from Fiat's successor entity, Fiat Chrysler Automobiles, in 2016. The company currently offers a large model range which includes several supercars, grand tourers, and one SUV. Many early Ferraris, dating to the 1950s and 1960s, count among the most expensive cars ever sold at auction. Throughout its history, the company has been noted for its continued participation in racing, especially in Formula One, where its team, Scuderia Ferrari, is the series' single oldest and most successful. Scuderia Ferrari has raced since 1929, first in Grand Prix events and later in Formula One, where it holds m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferrari 312 PB
The Ferrari 312 PB was a Group 6 prototype sports car introduced in 1971 by Italian carmaker Ferrari. It was officially designated the 312 P, but often known as the 312 PB to avoid confusion with a previous car of the same name. It was part of the Ferrari P series of Prototype-Sports Cars but was redesignated as a Group 5 Sports Car for 1972. Development In 1970, a change in the regulations for sportscar racing for 1972 was announced. The loophole for sports cars like Porsche 917, Ferrari 512, Ford GT40 and Lola T70, which could have engines up to 5 litre if a least 25 were made, was closed. The minimum weight of the 3-litre prototypes was raised to . Porsche considered this too heavy as their Porsche 908/03 were lighter, and this advantage would have been lost. On the other hand, their air-cooled two-valve engine was low on power with , and the development of a new normally aspirated race engine would have been necessary. In the following years, Porsche focussed on t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Franklin Engine Company
The Franklin Engine Company was an American manufacturer of aircraft engines. Its designs were used primarily in the civilian market, both in fixed wing and helicopter designs. It was briefly directed towards automobile engines as part of the Tucker Car Corporation, returning to aviation when that company failed. The company was later purchased by the Government of Poland. History The firm began as the H. H. Franklin Co. in 1902 in Syracuse, New York, US, to produce Franklin air-cooled automobiles. Barely surviving bankruptcy in 1933, the company was purchased by a group of ex-employees and renamed Air-cooled Motors in 1937. While the company kept the name of "Air-cooled Motors," its engines continued to be marketed under the Franklin name. Engineers Carl Doman and Ed Marks kept the company alive through the depression by manufacturing air-cooled truck and industrial engines. During World War II Air-cooled Motors was very successful producing helicopter and airplane engines. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panhard EBR
The Panhard EBR (Panhard ''Engin Blindé de Reconnaissance'', French: Armored Reconnaissance Vehicle) is an armoured car designed by Panhard for the French Army and later used across the globe, notably by the French Army during the Algerian War and by the Portuguese Army during the Portuguese Colonial War. Development history The EBR is an 8x8 wheeled reconnaissance vehicle based on the previous Panhard AM 40 P/Model 201, a light armored car born before the Second World War, but which remained only at prototype level. After the war, the new contest for a postwar armored car saw the Panhard proposal as winner against two other French firms. While the two basic concepts developed with the M.201 were retained (8 wheels and oscillating turret), the new armoured car was a new project, much heavier (13 t vs 8), with a larger crew (4 vs 2) and a 75 mm gun (vs 25 mm). Other innovations included new anti-bullet Michelin tyres and Veil-Picard tubes, which feature a series ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Tank Museum
The Tank Museum (previously the Bovington Tank Museum) is a collection of armoured fighting vehicles at Bovington Camp in Dorset, South West England. It is about north of the village of Wool and west of the major port of Poole. The collection traces the history of the tank with almost 300 vehicles on display. It includes Tiger 131, the only working example of a German Tiger I tank, and a British First World War Mark I, the world's oldest surviving combat tank. It is the museum of the Royal Tank Regiment and the Royal Armoured Corps and is a registered charity. History The writer Rudyard Kipling visited Bovington in 1923 and, after viewing the damaged tanks that had been salvaged at the end of the First World War, recommended that a museum be set up. A shed was established to house the collection but was not opened to the general public until 1947. George Forty, who was appointed director of the museum in 1982, expanded and modernized the collection. He retired in 1993 afte ...

Churchill Tank
The Tank, Infantry, Mk IV (A22) Churchill was a British infantry tank used in the Second World War, best known for its heavy armour, large longitudinal chassis with all-around tracks with multiple Bogie#Tracked vehicles, bogies, its ability to climb Grade (slope), steep slopes, and its use as the basis of many specialist vehicles. It was one of the heaviest Allies of World War II, Allied tanks of the war. The origins of the Churchill's design lay in the expectation that war in Europe might be fought in conditions similar to those of the First World War, and thus emphasised the ability to cross difficult ground. The Churchill was hurried into production in order to build up British defences against a possible German invasion. The first vehicles had flaws that had to be overcome before the Churchill was accepted for wide use. After several Mark (designation), marks (versions) had been built, a better-armoured specification, the Mark VII, entered service with the British Army. The ...

Henry Meadows
Henry Meadows, usually known simply as Meadows, of Wolverhampton, England, were major suppliers of Internal combustion engine, engines and transmission (mechanics), transmissions to the smaller companies in the British motor industry. Founded in 1920 in Park Lane, Wolverhampton, as a car gearbox maker, they expanded into petrol engines in 1922 and in the 1930s built a large factory in Fallings Park, Wolverhampton. Products Petrol engines Early production was connected with the move from W.H. Dorman & Co of the Dorman works manager (W.H. Dorman's son, John E. Dorman) in August 1921, and a design engineer Mr R.S. Crump. Dorman had been producing engines from 1903. The early Meadows engines and gearboxes were produced with Meadows-Dorman on the castings. This resulted in a court case between Dorman and Meadows, claiming that this was a misuse of the Dorman name and reputation. Dorman won the case One of the most popular petrol engines was the 1½-litre four-cylinder Type 4ED eng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Covenanter Tank
The Cruiser tank Mk V or A13 Mk III Covenanter was a British cruiser tank of the Second World War. The Covenanter was the first cruiser tank design to be given a name. Designed by the London, Midland and Scottish Railway as a better-armoured replacement for the Cruiser Mark IV, it was ordered into production in 1939 before pilot models were built. Problems with the design became apparent only after production was under way. The tank equipped various British armoured divisions for home defence and training. It never left the UK as poor engine cooling caused the Mk I to Mk III to be declared unfit for overseas service, especially in hot climates. This was rectified in the Mk IV after many corrective actions were undertaken but, by February 1944, it was declared obsolete. More than 1,700 of the type were built. It was named after the Covenanters, a Scottish religious and political movement at the time of the Wars of the Three Kingdoms. Development In 1938, the War Office had issu ...

Ferrari Testarossa
The Ferrari Testarossa (Type F110) is a 12-cylinder mid-engine sports car manufactured by Ferrari, which went into production in 1984 as the successor to the Ferrari Berlinetta Boxer. The Pininfarina-designed car was originally produced from 1984 until 1991, with two model revisions following the end of Testarossa production called the 512 TR and F512 M, which were produced from 1992 until 1996. Including revised variations, almost 10,000 cars in total were produced, making it at the time one of the most mass-produced Ferrari models. The Testarossa is a two-door coupé that premiered at the 1984 Paris Auto Show. All versions of the Testarossa were available with a rear-mounted, five-speed manual transmission. The rear mid-engine design (engine between the axles but behind the cabin) keeps the centre of gravity in the middle of the car, which increases stability and improves the car's cornering ability, and thus results in a standing weight distribution of 40% front: 60% re ...

Ferrari Berlinetta Boxer
The Ferrari Berlinetta Boxer (BB) is a series of sports cars produced by Ferrari in Italy between 1973 and 1984. The BB was designed by Leonardo Fioravanti at Pininfarina. The first BB model, the 365 GT4 BB, replaced the front engined Daytona and was the first in a series of road-going Ferraris equipped with a mid-mounted flat-twelve engine. The 365 GT4 BB was succeeded in 1976 by the BB 512, equipped with a larger displacement engine, then by the fuel-injected BB 512i in 1981. The series was discontinued in 1984 when the BB 512i was replaced by the Testarossa, which used a revised version of the flat-twelve engine. Background Production of the BB was a major step for Enzo Ferrari. He felt that a mid-engined road car would be too difficult for his buyers to handle, and it took many years for his engineers to convince him to adopt the layout. This attitude began to change as the marque lost its racing dominance in the late 1950s to mid-engined competitors. As a result, the rear ...

Mercedes-Benz C291
The Mercedes-Benz C291 was a sports-prototype racing car introduced for the 1991 World Sportscar Championship season. It was Mercedes-Benz’ final car in the Group C category. Introduction The 1991 season marked the introduction of the FIA’s new, and controversial, 3.5 litre formula which replaced the highly successful Group C category that had been used in the World Sportscar Championship since 1982, though due to a small number of entries for the 3.5 litre formula heavily penalised Group C cars (which were subject to weight penalties and started behind the new-style C1 entries on the grid) were allowed to participate in the season's C2 category. To meet the new regulations Mercedes-Benz came up with an all-new car; the C291 which was designed by its racing partner Sauber. One survived and is on display in the Carl Benz Museum in Ladenburg, Germany. Another one is located in the Michael Schumacher Collection in Cologne, and this is the Autopolis-winning chassis.
