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] |
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 ...

Ford 335 Engine
The Ford 335 engine family was a group of engines built by the Ford Motor Company between 1969 and 1982. The "335" designation reflected Ford management's decision to produce an engine of that size (335 cubic inches) with room for expansion during its development. This engine family began production in late 1969 with a 351 cu in (5.8 L) engine, commonly called the 351C. It later expanded to include a 400 cu in (6.6 L) engine which used a taller version of the engine block, commonly referred to as a tall deck engine block, a 351 cu in (5.8 L) tall deck variant, called the 351M, and a 302 cu in (4.9 L) engine which was exclusive to Australia. The 351C, introduced in 1969 for the 1970 model year, is commonly referred to as the 351 Cleveland after the Brook Park, Ohio, Cleveland Engine plant in which most of these engines were manufactured. This plant complex included a gray iron foundry (Cleveland Casting Plant), and two eng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saab Automobile
Saab Automobile AB () is a defunct car manufacturer that was founded in Sweden in 1945 when its parent company, Saab AB, began a project to design a small automobile. The first production model, the Saab 92, was launched in 1949. In 1968 the parent company merged with Scania-Vabis, and ten years later the Saab 900 was launched, in time becoming Saab's best-selling model. In the mid-1980s the new Saab 9000 model also appeared. In 1989, the automobile division of Saab-Scania was restructured into an independent company, Saab Automobile AB. The American manufacturer General Motors (GM) took 50 percent ownership. Two well-known models to come out of this period were the Saab 9-3 and the Saab 9-5. Then in 2000, GM exercised its option to acquire the remaining 50 percent. In 2010 GM sold Saab Automobile AB to the Dutch automobile manufacturer Spyker Cars N.V. After many years establishing a sound engineering reputation and ultimately a luxury price tag, Saab failed to build i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V8 Engine
A V8 engine is an eight-cylinder piston engine in which two banks of four cylinders share a common crankshaft and are arranged in a V configuration. The first V8 engine was produced by the French Antoinette company in 1904, developed and used in cars and speedboats but primarily aircraft; while the American 1914–1935 ''Cadillac L-Head'' engine is considered the first road going V8 engine to be mass produced in significant quantities. The popularity of V8 engines in cars was greatly increased following the 1932 introduction of the ''Ford Flathead V8''. In the early 21st century, use of V8 engines in passenger vehicles declined as automobile manufacturers opted for more fuel efficient, lower capacity engines, or hybrid and electric drivetrains. Design V-angle The majority of V8 engines use a V-angle (the angle between the two banks of cylinders) of 90 degrees. This angle results in good engine balance, which results in low vibrations; however, the downside is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maserati Shamal
The Maserati Shamal (''Tipo AM339'') is a two-door grand touring coupé produced by Italian automobile manufacturer Maserati from 1990 to 1996. In keeping with an established Maserati tradition, it is named after a wind: shamal (Arabic for ‘north’), a hot summer wind that blows in large areas of Mesopotamia, particularly in the large plain between the Tigris and Euphrates. With its newly developed twin-turbocharged V8, the Shamal was Maserati's flagship grand tourer, topping the lineup of V6-engined Biturbo coupés in both performance and price (at 125 million Lire). History The Shamal was introduced on 14 December 1989 in Modena, when Maserati president and owner Alejandro de Tomaso showed it to the press. It was the last model announced under the De Tomaso ownership: in January 1990, half of debt-plagued Maserati was acquired by Fiat S.p.A. Sales began in 1990. The final year of production for the Maserati Shamal was 1996; factory figures indicate that 369 examples were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

C20NE
The Family II is a straight-4 piston engine that was originally developed by Opel in the 1970s, debuting in 1979. Available in a wide range of cubic capacities ranging from 1598 to 2405 cc, it simultaneously replaced the Opel OHV, Opel CIH and Vauxhall Slant-4 engines, and was GM Europe's core powerplant design for much of the 1980s. The engine features a cast iron block, an aluminium head, and a timing belt driven valvetrain. The timing belt also drives the water pump. It was first used in the Opel Kadett D, Ascona B, Corsa, and their corresponding Vauxhall sister models, the Astra, Cavalier, and Nova. Many General Motors subsidiaries, including Daewoo, GM do Brasil, GM Powertrain, and Holden have used this design. By 1986, the Family II unit had completely supplanted the CIH engine as Opel's core 4-cylinder powerplant. although the 6-cylinder versions of the CIH continued in the larger Omega and Senator models until 1995.
