BMC C-Series Engine
The BMC C-Series is a straight-6 automobile engine produced from 1954 to 1971. Unlike the Austin-designed A-Series and B-Series engines, it came from the Morris Engines drawing office in Coventry and therefore differed significantly in its layout and design from the two other designs which were closely related. This was due to the C-Series being in essence an enlarged overhead valve development of the earlier 2.2 L Straight-6 overhead camshaft engine used in the post-war Morris Six MS and Wolseley 6/80 from 1948 until 1954, which itself also formed the basis of a related 1.5 L 4-cylinder engine for the Morris Oxford MO in side-valve form and the Wolseley 4/50 in overhead camshaft form. Displacement was 2.6 to 2.9 L with an undersquare stroke of , bored out to increase capacity. Mission The revised engine was required to replace BMC's inherited diverse collection of engines made to prewar designs and Austin's wartime designed four-cylinder BS1. A long-stroke engine, thoug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Motor Corporation
The British Motor Corporation Limited (BMC) was a UK-based vehicle manufacturer, formed in early 1952 to give effect to an agreed merger of the Morris and Austin businesses.Morris-Austin Merger Company Named. ''The Times'', Friday, 29 February 1952; pg. 9; Issue 52248 BMC acquired the shares in Morris Motors and the Austin Motor Company. Morris Motors, the holding company of the productive businesses of the Nuffield Organization, owned MG, Riley, and Wolseley. The agreed exchange of shares in Morris or Austin for shares in the new holding company, BMC, became effective in mid-April 1952. In September 1965, BMC took control of its major supplier of bodies, Pressed Steel, acquiring Jaguar's body supplier in the process. In September 1966, BMC absorbed with Jaguar Cars. In December 1966, BMC changed its name to British Motor Holdings Limited (BMH).British Motor Takes That New Label ''The Times'', Thursday, 15 December 1966; pg. 17; Issue 56815 BMH merged, in May 1968, with ...

Morris Engines
Morris Engines Limited was located in Coventry, Coventry, England. It specialised in the mass production of engines and gearboxes for vehicles made by W. R. Morris's businesses, later known as the Nuffield Organization. Morris Engines Ltd. was, therefore, partly responsible for Morris Motors Ltd. becoming Britain's leading motor manufacturer. Early years The Hotchkiss et Cie, Hotchkiss company of France, who were makers of the famous machine gun, hurriedly transferred production to England during World War I when it looked as if their Saint-Denis, Seine-Saint-Denis, St. Denis factory near Paris was going to be overrun by the Germans. Consequently, a factory was erected at Gosford Street, Coventry, and both machines and key staff were brought over to England so that production could start as soon as possible. At the end of the War in 1918, the factory suddenly became short of work so Hotchkiss agreed to manufacture engines and gearboxes, copied from American designs, for Morris ...

MG MGA
The MGA is a sports car that was produced by MG from 1955 until 1962. The MGA replaced the MG TF 1500 Midget and represented a complete styling break from MG's earlier sports cars. Announced on 26 September 1955 the car was officially launched at the Frankfurt Motor Show. A total of 101,081 units were marketed through the end of production in July 1962, the vast majority of which were exported. 5869 cars were sold on the home market, and the MGA was replaced by the MGB. Design The MGA design dates back to 1951, when MG designer Syd Enever created a streamlined body for George Philips' TD Le Mans car. The new bodywork traded the MG TF's articulated fenders and running board for ponton styling, with a single styled envelope fully enclosing the width and uninterrupted length of a car. The TF featured a high driver seating position. A new chassis was designed with the side members further apart and the floor attached to the bottom rather than the top of the frame sections. A p ...

Overhead Camshaft
An overhead camshaft (OHC) engine is a piston engine where the camshaft is located in the cylinder head above the combustion chamber. This contrasts with earlier overhead valve engines (OHV), where the camshaft is located below the combustion chamber in the engine block. ''Single overhead camshaft'' (SOHC) engines have one camshaft per bank of cylinders. ''Dual overhead camshaft'' (DOHC, also known as "twin-cam".) engines have two camshafts per bank. The first production car to use a DOHC engine was built in 1910. Use of DOHC engines slowly increased from the 1940s, leading to many automobiles by the early 2000s using DOHC engines. Design In an OHC engine, the camshaft is located at the top of the engine, above the combustion chamber. This contrasts the earlier overhead valve engine (OHV) and flathead engine configurations, where the camshaft is located down in the engine block. The valves in both OHC and OHV engines are located above the combustion chamber; however an OHV ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carburetor Icing
Carburetor icing, or carb icing, is an atmospheric icing, icing condition which can affect any carburetor under certain weather, atmospheric conditions. The problem is most notable in certain realms of aviation. Carburetor icing is caused by the temperature drop in the carburetor, as an effect of fuel vaporization, and the temperature drop associated with the pressure drop in the venturi effect, venturi. If the temperature drops below freezing, water vapor will freeze onto the throttle valve, and other internal surfaces of the carburetor. The Venturi effect can drop the ambient air temperature by 70 absolute degrees Fahrenheit (F) (40 degrees Celsius). In other words, air at an outside temperature of 100 degree F, can drop to 30 degrees F in the carburetor. Carburetor icing most often occurs when the outside air temperature is below 70 degrees F (21 degrees C) and the relative humidity is above 80 percent. Unfortunately, the warm air temperature often causes pilots of aircraft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carburettor
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 a ...

Harry Weslake
Weslake & Co also known as Weslake Research and Development was founded by Harry Weslake, described as England's greatest expert on cylinder head design, with premises in Rye, East Sussex, England. Weslake is most famous for its work with Bentley, Austin, Jaguar and the Gulf-Wyer Ford GT40 Mk.I. Early days Harry Weslake was born in Exeter in 1897 to Henry John Weslake, a director of Willey and Co, gas engineers, whom he would join from school. At 16, he modified a Rudge Multi to race at local hill climbing events. In World War I, he joined the Royal Flying Corp, against the wishes of his employers Willey & Co, who wanted him to continue his apprenticeship. When he was demobbed in 1919, he had already received his first patent with his father in 1918 for a device to improve carburettors. However both his parents died shortly after, and with no link to Willey's, Weslake left and set up a workshop with 3 others in Exeter. The workshop marketed his Wex carburettor design, whi ...

Combustion Chamber
A combustion chamber is part of an internal combustion engine in which the fuel/air mix is burned. For steam engines, the term has also been used for an extension of the firebox which is used to allow a more complete combustion process. Internal combustion engines In an internal combustion engine, the pressure caused by the burning air/fuel mixture applies direct force to part of the engine (e.g. for a piston engine, the force is applied to the top of the piston), which converts the gas pressure into mechanical energy (often in the form of a rotating output shaft). This contrasts an external combustion engine, where the combustion takes place in a separate part of the engine to where the gas pressure is converted into mechanical energy. Spark-ignition engines In spark ignition engines, such as petrol (gasoline) engines, the combustion chamber is usually located in the cylinder head. The engines are often designed such that the bottom of combustion chamber is roughly in li ... [...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] |

Undersquare
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] |
Morris Oxford MO
Morris Oxford Series MO is an automobile produced by Morris Motors of the United Kingdom from 1948 to 1954. It was one of several models to carry the Morris Oxford name between 1913 and 1971. __TOC__ Saloon After the Second World War the 13.5 fiscal horsepower Oxford MO had to replace the Ten horsepower series M, Morris's Twelve and Morris's Fourteen. It was announced along with the new 918cc Morris Minor and the 2.2-litre Morris Six MS on 26 October 1948 and was produced until 1954. The core design was shared with Nuffield Organization stable-mate Wolseley 4/50 which used a traditional grille and better finishes. Designed by Alec Issigonis, the Oxford, along with the Minor, introduced unit construction techniques such as Unibody construction even though it is not widely recognized as a true unibody car. Torsion bar front suspension was another novelty, and hydraulically operated 8-inch (200 mm) drum brakes were fitted all around. Under the bonnet, the MO was a step ...
