Lotus TwinCam
The Lotus-Ford Twin Cam is an inline-four petrol engine developed by Lotus for the 1962 Lotus Elan. A few early examples displaced 1.5 litres, but the majority were 1.55-litre (1557ml) engines. It used a Ford 116E iron cylinder block and a new aluminium cylinder head with dual overhead camshafts. The Twin Cam was used in a variety of vehicles until Lotus stopped production in 1973. It was succeeded by the Lotus 907 engine. History For the Lotus Elan, Lotus founder Colin Chapman wanted to find a less expensive engine than the costly all-alloy Coventry Climax FWE used in the original Lotus Elite. He felt that basing his new power-plant on an engine built in large volumes would keep costs down. Chapman initially chose the Ford 105E inline four used in the Ford Anglia as the basis of this new engine. The 105E displaced and had a cast iron block produced with Ford's thin-wall casting process, resulting in a relatively light part. While the 105E block only provided three main ...

Colin Chapman
Anthony Colin Bruce Chapman (19 May 1928 – 16 December 1982) was an English design engineer, inventor, and builder in the automotive industry, and founder of Lotus Cars. In 1952 he founded the sports car company Lotus Cars. Chapman initially ran Lotus in his spare time, assisted by a group of enthusiasts. His knowledge of the latest aeronautical engineering techniques would prove vital towards achieving the major automotive technical advances for which he is remembered. His design philosophy focused on cars with light weight and fine handling instead of bulking up on horsepower and spring rates, which he famously summarised as "Adding power makes you faster on the straights. Subtracting weight makes you faster everywhere." Under his direction, Team Lotus won seven Formula One Constructors' titles, six Drivers' Championships, and the Indianapolis 500 in the United States, between 1962 and 1978. The production side of Lotus Cars has built tens of thousands of relati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drive Chain
Chain drive is a way of transmitting mechanical power from one place to another. It is often used to convey power to the wheels of a vehicle, particularly bicycles and motorcycles. It is also used in a wide variety of machines besides vehicles. Most often, the power is conveyed by a roller chain, known as the drive chain or transmission chain, passing over a sprocket gear, with the teeth of the gear meshing with the holes in the links of the chain. The gear is turned, and this pulls the chain putting mechanical force into the system. Another type of drive chain is the Morse chain, invented by the Morse Chain Company of Ithaca, New York, United States. This has inverted teeth. Sometimes the power is output by simply rotating the chain, which can be used to lift or drag objects. In other situations, a second gear is placed and the power is recovered by attaching shafts or hubs to this gear. Though drive chains are often simple oval loops, they can also go around corners by placin ... [...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] |
Facel Vega
Facel S.A. was a French manufacturer of pressed steel automobile components, later complete automobiles of their own design. To intensify its World War II war effort, French subcontracting company for military aeronautics Bronzavia created a subsidiary called Facel (acronym of ''Forges et Ateliers de Constructions d'Eure-et-Loir'') in December 1939. After the war, in 1945, by merging with Métallon, Facel began to make short-run special bodies, coupés or cabriolets for Simca, Ford of France, Panhard and Delahaye. Approximately 2,900 cars of all models were hand-built in Facel's short life. Unitary bodies without a chassis became general for mass-produced cars, and Facel lost its big customers. French niche manufacturers ceased production. Métallon left the partnership in 1953, and Facel set about designing and making its own complete cars using engines made by Chrysler, Volvo and Austin. Its first design, named Vega, was shown to the public in 1954. The Facellia model, intr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean Daninos
Jean Daninos (2 December 1906 – 13 October 2001) was a Greek-French constructor of luxury cars Facel Vega, born in Paris. The brother of the Pierre Daninos, Jean Daninos had founded the company FACEL (Forges et Ateliers des Constructions d'Eure-et-Loir, ''forge and construction workshop for the department of Eure-et-Loir'') in 1939 with hopes of one day designing and manufacturing his own automobile. An engineer, he had previously collaborated with Citroën on the Traction Avant and had worked in the aviation field. The FACEL company produced the bodies of custom cars like the Panhard Dyna cabriolet and the Ford Comète. The first Facel Vega model, designed by Daninos himself, debuted in 1954, equipped with a Chrysler engine. Daninos counted among his clients celebrities including (Tony Curtis, Ava Gardner) and racing drivers ( Stirling Moss, Maurice Trintignant). Several sports car models followed until the company's demise in the mid-1960s. During ten years of production, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harry Mundy
Harry Mundy (1915–1988) was a British car engine designer and motoring magazine editor. He was educated at King Henry VIII School in Coventry and went on to serve his apprenticeship with Alvis. He left them in 1936 to join English Racing Automobiles (ERA) in Bourne, Lincolnshire as a draughtsman. Also at ERA was Walter Hassan who became a lifelong friend; the two would work together later at Jaguar on engine development. He left ERA in 1939 and returned to Coventry to work at the Morris Engines factory. After World War II he moved to British Racing Motors (BRM) in 1946 as head of the design office, being involved in the design of the BRM V16 Formula One engine, before moving on again in 1950 to Coventry Climax engines as chief designer working on the FWA engine. His career then took a change in direction and he moved into journalism becoming Technical Editor of '' The Autocar'' magazine in 1955 but while there he also worked on the design of the Ford based twin-cam engine ...

Ford Consul Classic
The Ford Consul Classic is a mid-sized car that was launched in May 1961 and built by Ford UK from 1961 to 1963. It was available in two or four door saloon form, in Standard or De Luxe versions, and with floor or column gearshift. The name Ford Consul 315 was used for export markets. The Ford Consul Capri was a 2-door coupé version of the Classic, and was available from 1961 until 1964. The four-cylinder pre-crossflow Kent engine was replaced in August 1962 by an over-square engine with a new five-bearing crankshaft and a new gearbox with synchromesh on all four forward ratios. Steering and suspension also received "greased for life" joints. It is sometimes referred to as the Ford 109E, though that was only one of four such codes utilized for the Consul Classic, as explained below. Obvious competitor models at the time included the Hillman Minx and Singer Gazelle from Rootes Group. __TOC__ Ford Classic model codes The Classic (and related Consul Capri) had the right-ha ...

Oversquare
In a reciprocating piston engine, the stroke ratio, defined by either bore/stroke ratio or stroke/bore ratio, is a term to describe the ratio between cylinder bore diameter and piston stroke length. This can be used for either an internal combustion engine, where the fuel is burned within the cylinders of the engine, or external combustion engine, such as a steam engine, where the combustion of the fuel takes place ''outside'' the working cylinders of the engine. A fairly comprehensive yet understandable study of stroke/bore effects was published in ''Horseless Age'', 1916. Conventions In a piston engine, there are two different ways of describing the ''stroke ratio'' of its cylinders, namely: ''bore/stroke'' ratio, and ''stroke/bore'' ratio. Bore/stroke ratio Bore/stroke is the more commonly used term, with usage in North America, Europe, United Kingdom, Asia, and Australia. The diameter of the cylinder bore is divided by the length of the piston stroke to give the ratio. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Engine Displacement
Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. It is commonly used as an expression of an engine's size, and by extension as a loose indicator of the power an engine might be capable of producing and the amount of fuel it should be expected to consume. For this reason displacement is one of the measures often used in advertising, as well as regulating, motor vehicles. It is usually expressed using the metric units of cubic centimetres (cc or cm3, equivalent to millilitres) or litres (l or L), orparticularly in the United States cubic inches (CID, cu in, or in3). Definition The overall displacement for a typical reciprocating piston engine is calculated by multiplying together three values; the distance travelled by the piston (the stroke length), the circular area of the cylinder, and the number of cylinders in the whole engine. The formula is: : \text = \text \times \frac \times ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
