Oversquare
Stroke ratio, today universally defined as bore/stroke ratio, is a term to describe the ratio between cylinder bore diameter and piston stroke length in a reciprocating piston engine. 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. Conventions The contemporary convention for describing the ''stroke ratio'' of a piston engine‘s cylinders is its ''bore/stroke'' ratio. ''Stroke/bore'' ratio is an obsolete expression dating to the early era of reciprocating engine development. Bore/stroke ratio The diameter of the cylinder bore is divided by the length of the piston stroke to give the ratio. Square, oversquare and undersquare engines The following terms describe the naming conventions for the configurations of the various bore/stroke ratio: Square A square ...

Ferrari Lampredi Engine
The Ferrari Lampredi engine was a naturally aspirated all aluminum 60° V12 engine produced between 1950 and 1959. Inline-4 and Inline-6 variants for racing were derived from it. Aurelio Lampredi designed a number of racing engines for Ferrari. He was brought on to hedge the company's bets with a different engine family than the small V12s designed by Gioacchino Colombo. Variants of his design powered the company to a string of world championships in the 1950s. All were quickly abandoned due to changing engine displacement sizes (because, starting in 1958, the sports regulations required sport cars to have engines within 3 litres), with the Dino V6 and V8 taking the place of the fours and sixes and evolution of the older Colombo V12 continuing as the company's preeminent V12. V12 275 After little luck in Formula One with the supercharged Colombo V12, Ferrari returned to natural aspiration. The task of creating the new V12 for Formula One use fell to Aurelio Lampredi, who desig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reciprocating Engine
A reciprocating engine, more often known as a piston engine, is a heat engine that uses one or more reciprocating pistons to convert high temperature and high pressure into a rotating motion. This article describes the common features of all types. The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the Industrial Revolution; and the Stirling engine for niche applications. Internal combustion engines are further classified in two ways: either a spark-ignition (SI) engine, where the spark plug initiates the combustion; or a compression-ignition (CI) engine, where the air within the cylinder is compressed, thus heating it, so that the heated air ignites fuel that is injected then or earlier.''Thermodynamics: An Engineering Approach'' by Yunus A. Cengal and Michael A. Boles Common features in all types There may be one or more pistons. Each piston is inside a cylinder, into which a gas is introduced, e ...

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. In steam locomotives The term bore also applies to the cylinder of a steam locomotive or steam engine. Bore pitch Bore pitch is the distance between the centerline of a cylinder bore to the centerline of the next cylinder bore adjacent to it in an internal combustion engine. It's also referred to as the "mean cylinder width", "bore spacing", "bore center distance" and "cylinder spacing". The bore pitch is always larger than the inside diameter of the cylinder (the bore and piston diameter) sinc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maserati Quattroporte IV
The Maserati Quattroporte () is a four-door full-size luxury sedan produced by Italian automobile manufacturer Maserati. The name translated from Italian means " four doors". The production of the sixth generation ended in late 2023, with the first generation introduced in 1963. Quattroporte I (AM107, 1963–1969) The original Maserati Quattroporte (''Tipo AM107'') was built between 1963 and 1969. It was a large saloon powered by V8 engines—both firsts for a series production Maserati automobile. History The task of styling the Quattroporte was given to Turinese coachbuilder Pietro Frua, who drew inspiration from a special 5000 GT (chassis number 103.060) which he had designed in 1962 for Prince Karim Aga Khan. While the design was by Frua, body construction was carried out by Vignale. Series I (1963–1966) The Quattroporte was introduced at the October–November 1963 Turin Motor Show, where a pre-production prototype was on the Maserati stand next to the ...

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 wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kawasaki Z1
The Kawasaki Z1 is a four-cylinder, air-cooled, double-overhead camshaft, carbureted, chain-drive motorcycle introduced in 1972 by Kawasaki. Following the introduction of Honda's CB750 in 1968, the Z1 helped popularize the in-line, across-the-frame four-cylinder, a format that became known as the '' Universal Japanese Motorcycle'' or ''UJM.'' The Z1 was noted for being the first large-capacity Japanese four-cylinder motorcycle to use the double-overhead-camshaft system on a production motorcycle. When it was introduced, only the MV Agusta 750 S used this system; it was a very expensive limited-production machine, as opposed to the Kawasaki which was less than half the price. Marketed variously as the Z1-900, 900 Z1 or 900 S4 ("Super Four"), the Z1 was the first of Kawasaki's Z models. History The Kawasaki Z1 was developed under the project name "New York Steak". In the late 1960s Kawasaki, already an established manufacturer of two-stroke motorcycles, had begun prototyping ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
