Jaguar V12 Engine
The Jaguar V12 engine is a V12 internal combustion engine produced by Jaguar Cars. The engine was based on a prototype design by Claude Baily for an intended Le Mans car—the Jaguar XJ13. The XJ13 project was terminated in 1966 before the car was ever entered into competition, but under the direction of Jaguar Chief Engineer William Heynes the V12 engine design was reworked by engineers Walter Hassan and Harry Mundy into a production-ready version, first installed in the Series 3 Jaguar E-Type of 1971. The V12 was the second production engine design in Jaguar's history. The all-aluminium block was fitted with removable wet iron liners, complete with single overhead camshaft aluminium heads with two valves per cylinder. It was regarded as one of the premier power plants of the 1970s and 1980s. Development Initial designs for a V12 engine were produced by engineer Claude Baily as early as 1951, with a view to using it in a Le Mans car. Baily's original 8.0 L design used double o ...

Jaguar Cars
Jaguar (, ) is the luxury vehicle brand of Jaguar Land Rover, a British multinational car manufacturer with its headquarters in Whitley, Coventry, England. Jaguar Cars was the company that was responsible for the production of Jaguar cars until its operations were fully merged with those of Land Rover to form Jaguar Land Rover on 1 January 2013. Jaguar's business was founded as the Swallow Sidecar Company in 1922, originally making motorcycle sidecars before developing bodies for passenger cars. Under the ownership of S. S. Cars Limited, the business extended to complete cars made in association with Standard Motor Co, many bearing ''Jaguar'' as a model name. The company's name was changed from S. S. Cars to Jaguar Cars in 1945. A merger with the British Motor Corporation followed in 1966, the resulting enlarged company now being renamed as British Motor Holdings (BMH), which in 1968 merged with Leyland Motor Corporation and became British Leyland, itself to be nationali ...

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 ...

Stroke (engine)
In the context of an internal combustion engine, the term stroke has the following related meanings: * A phase of the engine's cycle (e.g. compression stroke, exhaust stroke), during which the piston travels from top to bottom or vice versa. * The type of power cycle used by a piston engine (e.g. two-stroke engine, four-stroke engine). * "Stroke length", the distance travelled by the piston during each cycle. The stroke length––along with bore diameter––determines the engine's displacement. Phases in the power cycle Commonly used engine phases or strokes (i.e. those used in a four-stroke engine) are described below. Other types of engines can have very different phases. Induction-intake stroke The induction stroke is the first phase in a four-stroke (e.g. Otto cycle or Diesel cycle) engine. It involves the downward movement of the piston, creating a partial vacuum that draws a air-fuel mixture (or air alone, in the case of a direct injection engine) into the combus ...

Bore (engine)
In a piston engine, the bore (or cylinder bore) is the diameter of each cylinder. Engine displacement is calculated based on bore, stroke length and the number of cylinders: displacement = The stroke ratio, determined by dividing the bore by the stroke, traditionally indicated whether an engine was designed for power at high engine speeds (rpm) or torque at lower engine speeds. The term "bore" can also be applied to the bore of a locomotive cylinder or steam engine pistons. Steam locomotive The term bore also applies to the cylinder of a steam locomotive or steam engine. See also * Bore pitch * Compression ratio * 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 ... References {{Steam engine configurations Engine technology ...

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] |
