Triumph Spitfire
The Triumph Spitfire is a British sports car and manufactured over five production iterations between 1962-1980. Styled for Standard-Triumph in 1957 by Italian designer Giovanni Michelotti, the Spitfire was introduced at the London Motor Show in 1962. It was manufactured at the Standard-Triumph Canley works, with approximately 315,000 produced over 18 years. Developed on a shortened variant of the Triumph Herald saloon/sedan's chassis, the Spitfire shared the Herald's running gear and Standard SC engine. The design used body-on-frame construction, augmented by structural components within the bodywork and rear trailing arms attached to the body rather than the chassis. A manually deployable convertible top, substantially improved on later models, provided weather protection and a bespoke hard-top was available as a factory option. Popular in street and rally racing, Spitfires won numerous SCCA National Sports Car Championships in F and G Production classes; won its class at th ...

Standard Motor Company
The Standard Motor Company Limited was a motor vehicle manufacturer, founded in Coventry, England, in 1903 by Reginald Walter Maudslay. For many years, it manufactured Ferguson TE20 tractors powered by its Vanguard engine. All Standard's tractor assets were sold to Massey Ferguson in 1959. Standard purchased Triumph Motor Company, Triumph in 1945 and in 1959 officially changed its name to Standard-Triumph International and began to put the Triumph brand name on all its products. A new subsidiary took the name The Standard Motor Company Limited and took over the manufacture of the group's products. The Standard name was last used in Britain in 1963, and in India in 1988. History 1903–14 Maudslay, great-grandson of the eminent engineer Henry Maudslay, had trained under John Wolfe-Barry, Sir John Wolfe-Barry as a civil engineer. In 1902 he joined his cousin Cyril Charles Maudslay at his Maudslay Motor Company to make marine internal combustion engines. The marine engines did not ...

Alpine Rally
The Alpine Rally, also known by its official name Coupe des Alpes, was a rally competition based in Marseille and held from 1932 to 1971. In the 1950s and the 1960s, it was among the most prestigious rallies in the world and featured an international route, consisting of famous mountain passes in Europe. History The rally was first held in 1932 under the name ''Rallye des Alpes Françaises''. After World War II, it continued as the ''Rallye International des Alpes'' in 1946. Although the event still started and finished in France, the route became international in 1948 and until 1965 featured famous mountain passes in Austria, Germany, Italy and Switzerland. In 1953, the Alpine Rally was included in the inaugural European Rally Championship (ERC) calendar. The rally was very popular during its heyday; '' Autocar'' wrote in 1958 that "without doubt, the Alpine Rally was one of the most formidable motoring events of any type in the international calendar." The car manufacturer Alpi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SU Carburetor
SU carburettors were a British manufacturer of constant-depression carburettors. Their designs were in mass production during most of the twentieth century. The S.U. Carburetter Company Limited also manufactured dual-choke updraught carburettors for aero-engines such as the Rolls-Royce Merlin and Rolls-Royce Griffon.

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] |
Overhead Valve
An overhead valve (OHV) engine, sometimes called a ''pushrod engine'', is a piston engine whose valves are located in the cylinder head above the combustion chamber. This contrasts with earlier flathead engines, where the valves were located below the combustion chamber in the engine block. Although an overhead camshaft (OHC) engine also has overhead valves, the common usage of the term "overhead valve engine" is limited to engines where the camshaft is located in the engine block. In these traditional OHV engines, the motion of the camshaft is transferred using pushrods (hence the term "pushrod engine") and rocker arms to operate the valves at the top of the engine. Some early intake-over-exhaust engines used a hybrid design combining elements of both side-valves and overhead valves. History Predecessors The first internal combustion engines were based on steam engines and therefore used slide valves. This was the case for the first Otto engine, which was first succ ...

Overdrive (mechanics)
Overdrive is the operation of an automobile cruising at sustained speed with reduced engine revolutions per minute (RPM), leading to better fuel consumption, lower noise, and lower wear. The term is ambiguous. The most fundamental meaning is that of an overall gear ratio between engine and wheels, such that the car is ''over-geared'', and cannot reach its potential top speed, i.e. the car could travel faster if it were in a lower gear, with the engine turning at higher RPM. The power produced by an engine increases with the engine's RPM to a maximum, then falls away. The point of maximum power is somewhat lower than the absolute maximum RPM to which the engine is limited, the " redline" RPM. A car's speed is limited by the power required to drive it against air resistance, which increases with speed. At the maximum possible speed, the engine is running at its point of maximum power, or ''power peak'', and the car is traveling at the speed where air resistance equals that max ...

Manual Transmission
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canada, the United Kingdom, and the United States), or stick shift (in the United States), is a multi-speed motor vehicle transmission (mechanics), transmission system, where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually a foot pedal for cars or a hand lever for motorcycles). Early automobiles used ''sliding-mesh'' manual transmissions with up to three forward gear ratios. Since the 1950s, ''constant-mesh'' manual transmissions have become increasingly commonplace and the number of forward ratios has increased to 5-speed and 6-speed manual transmissions for current vehicles. The alternative to a manual transmission is an automatic transmission; common types of automatic transmissions are the Automatic transmission#Hydraulic automatic transmissions, hydraulic automatic transmission (AT), and the continuously variable transmissio ...

Straight-four Engine
A straight-four engine (also called an inline-four) is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. The vast majority of automotive four-cylinder engines use a straight-four layout (with the exceptions of the flat-four engines produced by Subaru and Porsche) and the layout is also very common in motorcycles and other machinery. Therefore the term "four-cylinder engine" is usually synonymous with straight-four engines. When a straight-four engine is installed at an inclined angle (instead of with the cylinders oriented vertically), it is sometimes called a slant-four. Between 2005 and 2008, the proportion of new vehicles sold in the United States with four-cylinder engines rose from 30% to 47%. By the 2020 model year, the share for light-duty vehicles had risen to 59%. Design A four-stroke straight-four engine always has a cylinder on its power stroke, unlike engines with fewer cylinders where there is no power stroke occu ...

MG Midget
The MG Midget is a small two-seater sports car produced by MG from 1961 to 1979. It revived a name that had been used on earlier models such as the MG M-type, MG D-type, MG J-type and MG T-type. MG Midget MkI (1961–64) The first version, announced at the end of June 1961, was essentially a slightly more expensive badge-engineered version of the MkII Austin-Healey Sprite deluxe version. The original 'frogeye' Sprite had been introduced specifically to fill the gap in the market left by the end of production of the MG T-type Midget as its replacement, the MGA had been a significantly larger and more expensive car with greater performance. Many existing MG buyers turned to the Sprite to provide a modern low-cost sports car and so a badge-engineered MG version reusing the Midget name made sense. The new Midget differed from the Sprite only in grille design, badging, improved interior trim, better instruments and added external polished trim to justify its higher price. Mechani ...

Monocoque
Monocoque ( ), also called structural skin, is a structural system in which loads are supported by an object's external skin, in a manner similar to an egg shell. The word ''monocoque'' is a French term for "single shell". First used for boats, a true monocoque carries both tensile and compressive forces within the skin and can be recognised by the absence of a load-carrying internal frame. Few metal aircraft other than those with milled skins can strictly be regarded as pure monocoques, as they use a metal shell or sheeting reinforced with frames riveted to the skin, but most wooden aircraft are described as monocoques, even though they also incorporate frames. By contrast, a semi-monocoque is a hybrid combining a tensile stressed skin and a compressive structure made up of longerons and ribs or frames. Other semi-monocoques, not to be confused with true monocoques, include vehicle unibodies, which tend to be composites, and inflatable shells or balloon tanks, both of which ...

Austin A30
The Austin A30 is a small family car produced by Austin from May 1952 to September 1956. It was launched at the 1951 Earls Court Motor Show as the "''New'' Austin Seven" and was Austin's competitor with the Morris Minor. At launch, the car cost £507 (equivalent to £15,793.36 in 2019) undercutting the Minor by £62. Styling Though Austin had previously contracted the American industrial designer, Raymond Loewy in the task, the designs of Holden 'Bob' Koto were discarded and the car we know was eventually styled in-house by Ricardo 'Dick' Burzi. Features The body structure was designed by T.K. Garrett, who had been an aeronautical engineer before joining Austin. It was of fully stressed monocoque chassis-less construction, which made it lighter and stiffer than most contemporary vehicles, the first Austin to be made in this way. Inside there were individual seats at the front and a bench at the rear covered in PVC with an option of leather facings on the seats. Evidence of ...
