Douvrin Engine
The Douvrin family was an all-aluminum inline-four automobile engine designed in the early 1970s and produced from 1977 to 1996 by ''Compagnie Française de Mécanique'', a joint-venture between PSA and Renault located in the town of Douvrin in northern France. This engine is designed by the engineer Jean-Jacques His (father of Formula 1 engines from Renault and Ferrari). It was produced in the same factory as the ''PRV'' V6, which also is sometimes known outside France as the "Douvrin" V6. The Douvrin engine is also referred to as the ZDJ/ZEJ engine by Peugeot, and as the J-type engine by Renault. Construction This engine had an aluminium alloy block with cast iron liners, and an aluminium alloy head with one overhead camshaft driven by belt. Its displacement varied from 1995 to 2165 cc. This engine should not be confused with the PSA-Renault X-Type engine whose displacement varied from 954 to 1360 cc and had a gearbox integrated to the block. The Douvrin engine on the contrary, ...

Inline-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 ...

Piston Engine
A reciprocating engine, also often known as a piston engine, is typically 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 intro ...

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]   |

Belt Drive
A belt is a loop of flexible material used to link two or more rotating shafts mechanically, most often parallel. Belts may be used as a source of motion, to transmit power efficiently or to track relative movement. Belts are looped over pulleys and may have a twist between the pulleys, and the shafts need not be parallel. In a two pulley system, the belt can either drive the pulleys normally in one direction (the same if on parallel shafts), or the belt may be crossed, so that the direction of the driven shaft is reversed (the opposite direction to the driver if on parallel shafts). The belt drive can also be used to change the speed of rotation, either up or down, by using different sized pulleys. As a source of motion, a conveyor belt is one application where the belt is adapted to carry a load continuously between two points. History The mechanical belt drive, using a pulley machine, was first mentioned in the text the ''Dictionary of Local Expressions'' by the Han Dyna ...

Oversquare
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]   |

PSA-Renault X-Type Engine
The PSA X engine is a family of internal combustion engines used in Citroën, Peugeot, Talbot and Renault automobiles. The X family was mainly used in superminis and the entry level models of midsize vehicles. It was designed and manufactured by the company "Française de Mécanique", a joint venture created by Peugeot (as predecessor to Groupe PSA) and Renault in 1969, and built in Douvrin in northern France. It is commonly called the "Suitcase" engine, the "Douvrin" nickname being commonly given to the bigger 2.0-2.2 L J-Type engine, which was also built in Douvrin. The X design was introduced in 1972 with the Peugeot 104. It was an all-aluminium alloy SOHC inline-four design with two valves per cylinder driven by a chain, using petrol as fuel. It was applied transversely in front wheel drive vehicles only, tilted by an almost horizontal attitude of 72°. The integral transmission is mounted on the rear side of the crankcase (thus appearing to be underneath the power unit whe ...

Peugeot
Peugeot (, , ) is a French brand of automobiles owned by Stellantis. The family business that preceded the current Peugeot companies was founded in 1810, with a steel foundry that soon started making hand tools and kitchen equipment, and then bicycles. On 20 November 1858, Émile Peugeot applied for the lion trademark. Armand Peugeot (1849–1915) built the company's first car steam tricycle, in collaboration with Léon Serpollet in 1889; this was followed in 1890 by an internal combustion car with a Panhard- Daimler engine. The Peugeot company and family are originally from Sochaux. Peugeot retains a large manufacturing plant and Peugeot museum there. In February 2014, the shareholders agreed to a recapitalisation plan for the PSA Group, in which Dongfeng Motors and the French government each bought a 14% stake in the company. Peugeot has received many international awards for its vehicles, including six European Car of the Year awards. Peugeot has been involved suc ...

PRV Engine
The V6 PRV engine is an automobile petrol V6 engine that was developed jointly by Peugeot, Renault and Volvo Cars – and sold from 1974 to 1998. It was gradually replaced after 1994 by another joint PSA-Renault design, known as the ''ES'' engine at PSA and the ''L'' engine at Renault. It was designed and manufactured by the company "Française de Mécanique" for PSA, Renault and Volvo. Corporate history In 1966, Peugeot and Renault entered a cooperative agreement to manufacture common components. The first joint subsidiary, ''La Française de Mécanique'' (also called ''Compagnie Française de Mécanique'' or simply ''FM'') was launched in 1969. The FM factory was built in Douvrin near Lens in northern France. The PRV engines are sometimes referred to as "Douvrin" engines, though that name is more commonly applied to a family of straight-fours produced at the same time. In 1971, Volvo joined Peugeot and Renault in the creation of the PRV company, a public limited company (p ...

Ferrari
Ferrari S.p.A. (; ) is an Italian luxury sports car manufacturer based in Maranello, Italy. Founded by Enzo Ferrari (1898–1988) in 1939 from the Alfa Romeo racing division as ''Auto Avio Costruzioni'', the company built its first car in 1940, and produced its first Ferrari-badged car in 1947. Fiat S.p.A. acquired 50% of Ferrari in 1969 and expanded its stake to 90% in 1988. In October 2014, Fiat Chrysler Automobiles (FCA) announced its intentions to separate Ferrari S.p.A. from FCA; as of the announcement FCA owned 90% of Ferrari. The separation began in October 2015 with a restructuring that established Ferrari N.V. (a company incorporated in the Netherlands) as the new holding company of the Ferrari S.p.A. group, and the subsequent sale by FCA of 10% of the shares in an IPO and concurrent listing of common shares on the New York Stock Exchange. Through the remaining steps of the separation, FCA's interest in Ferrari's business was distributed to shareholders of FCA, ...

Formula 1
Formula One (also known as Formula 1 or F1) is the highest class of international racing for open-wheel single-seater formula racing cars sanctioned by the Fédération Internationale de l'Automobile (FIA). The World Drivers' Championship, which became the FIA Formula One World Championship in 1981, has been one of the premier forms of racing around the world since its inaugural season in 1950. The word ''formula'' in the name refers to the set of rules to which all participants' cars must conform. A Formula One season consists of a series of races, known as ''Grands Prix'', which take place worldwide on both purpose-built circuits and closed public roads. A points system is used at Grands Prix to determine two annual World Championships: one for drivers, the other for constructors. Each driver must hold a valid Super Licence, the highest class of racing licence issued by the FIA. The races must run on tracks graded "1" (formerly "A"), the highest grade-rating issue ...

Douvrin
Douvrin (; vls, Doverin) is a commune in the Pas-de-Calais department in the Hauts-de-France region of France. Geography Douvrin is an ex-coalmining town some east of Béthune and southwest of Lille, at the junction of the D165, the D163 and the N47 roads. Since the mid-1960s, farming and light industry have replaced coal mining as the principle occupations. History First recorded in the eleventh century, the town has been known by several variations of the name: Doverin (in 1098), Dovring (in 1120), Dovrin (in 1149), Dovrign (in 1218), Douvringnum (in 1229), Douvrin (in the fifteenth century) and also as Douvrain (in 1652). The town suffered considerable damage during World War I. Coal mining was the main livelihood here for around 100 years, from the mid-nineteenth century until the 1960s when the reserves became uneconomic. Since 1969, Française de Mécanique, part of PSA Peugeot Citroen has produced motor-car engines at the plant immediately north of the commune. Over 3, ...
