A V4 engine is a four-cylinder piston engine where the cylinders share a common crankshaft and are arranged in a V configuration.
A flat engine is a piston engine where the cylinders are located on either side of a central crankshaft. Flat engines are also known as horizontally opposed engines, however this is distinct from the less common opposed-piston engine design, whereby each cylinder has two pistons sharing a central combustion chamber.
A flat-twin engine is a two-cylinder internal combustion engine with the cylinders on opposite sides of the crankshaft. The most common type of flat-twin engine is the boxer-twin engine, where both pistons move inwards and outwards at the same time.
A straight-twin engine, also known as an inline-twin, vertical-twin, or parallel-twin, is a two-cylinder piston engine whose cylinders are arranged in a line along a common crankshaft.
A straight-three engine is a three-cylinder piston engine where cylinders are arranged in a line along a common crankshaft.

The Swift Motor Company made Swift Cars in Coventry, England from 1900 until 1931. It grew progressively from James Starley's Coventry Sewing Machine Company, via bicycle and motorised cycle manufacture. The cars ranged from a single-cylinder car in 1900 using an MMC engine, through a Swift-engined twin-cylinder 7-horsepower light car in 1904, and a 3-litre model in 1913. After the First World War a successful range was sold during the 1920s, but the Cadet of 1930 was its last vehicle as it could not compete economically with volume manufacturers such as Ford and Morris Motors.
A motorcycle engine is an engine that powers a motorcycle. Motorcycle engines are typically two-stroke or four-stroke internal combustion engines, but other engine types, such as Wankels and electric motors, have been used.
A single-cylinder engine, sometimes called a thumper, is a piston engine with one cylinder. This engine is often used for motorcycles, motor scooters, go-karts, all-terrain vehicles, radio-controlled vehicles, portable tools and garden machinery. Single-cylinder engines are made both as 4-strokes and 2-strokes.
Wooler was a British manufacturer of motorcycles and automobiles, founded by engineer John Wooler in 1911 based in Alperton, Middlesex. The company became known for its unconventional designs which included several fore-and-aft twins, a vertical camshaft single cylinder machine, a transverse-four beam engine, and a transverse flat four. Most machines possessed Wooler's enduring design features of a petrol tank which extended past the steering head.
Ariel Motorcycles was a British maker of bicycles and then motorcycles in Bournbrook, Birmingham. It was an innovator in British motorcycling, part of the Ariel marque. The company was sold to BSA in 1951 but the brand survived until 1967. Influential Ariel designers included Val Page and Edward Turner. The last motorcycle-type vehicle to carry the Ariel name was a short-lived three-wheel tilting moped in 1970.
Douglas was a British motorcycle manufacturer from 1907 to 1957 based in Kingswood, Bristol, owned by the Douglas family, and especially known for its horizontally opposed twin cylinder engined bikes and as manufacturers of speedway machines. The company also built a range of cars between 1913 and 1922.
Rex, Rex Motorcycles, Rex-Acme, was a car and motorcycle company which began in Birmingham, England in 1900. Rex soon merged with a Coventry maker of bicycles and cars named Allard and then later in 1922 the company merged with Coventry's 'Acme' motorcycle company forming 'Rex Acme'. The company existed until 1933, and, in its heyday, was considered one of the greatest names in the British motorcycle industry.
The Advance Motor Manufacturing Company was a British motorcycle and engine manufacturer established in 1905. As well as supplying aircraft engines to the pioneering monoplane developers, Advance engines were also used by Captain Robert Scott to power Antarctic snow sleds. After the end of the Second World War the company was sold to Sheepbridge Engineering and became a motor supplies organisation.
The Standard wet liner inline-four engine was an inline four cylinder petrol engine produced by the Standard Motor Company. Originally developed concurrently for passenger car use and for the Ferguson TE20 tractor, it was widely used for Standard passenger cars of the 1950s, most notably the Vanguard. Later it was successfully used in Standard's popular early generation Triumph TR series sports cars.
W.H. Dorman & Co was a company formed by William Henry Dorman in 1870 making cutting tools for the footwear industry. It diversified into other tools including grinders, and in 1903 into internal combustion engines. This was to be its main product up to the point where it was taken over by the English Electric Company in 1961, though the Dorman name continued as a diesel engine trademark until 1995. William Henry Dorman retired in 1911, and died in 1926.
F. E. Baker Ltd was a British motorcycle engine and cyclecar engine manufacturer based in the Precision Works, Moorsom Street, Birmingham, England. Founded in 1906 by Frank Edward Baker, the company produced motorcycle engines under the Precision trademark until 1919. Precision engines were used by a wide range of motorcycle manufacturers in the United Kingdom and in other parts of the Commonwealth and were also used in cyclecars. Many manufacturers used the 'Precision' trademark as part of their model names, and in 1912 there was a 'Precision' motorcycle sold in Australia, but it is unclear if this was manufactured by F. E. Baker or just permitted use of the trademark by a motorcycle manufacturer.
The Turner Manufacturing Company was an engineering company based in Wolverhampton, England. Among their products were steam and petrol cars, small boat engines, the Turner winch, a range of diesel engines made in the 1940s and 1950s, the Yeoman of England agricultural tractor, and truck transmissions - the latter leading to their eventual takeover.
