PSA XU Engine
The PSA XU is a family of internal combustion engines used in Citroën and Peugeot automobiles. It became the dominant mid-size engine in Peugeot and Citroën products through the 1980s and 1990s. The XU design was introduced in 1981 with the Peugeot 305. It was a SOHC or DOHC straight-4 design with two or four valves per cylinder, using petrol as fuel. It was applied transversely in front wheel drive vehicles only, tilted by 30°. Displacement ranged between , and all production XU gasoline engines had a bore of . The engine uses an aluminium cylinder head in all models. All models' blocks are made, except XU10, in cast aluminium alloy with removable cast iron wet cylinder liners. XU10 blocks are made in cast iron, with bores machined directly in the block, without removable cylinder liners. Its first Citroën application was on the Citroën BX in 1982, where it appeared in format. The XU was replaced by the more modern EW/DW family. XU5 The XU5 had a displacement of , w ...

Straight-four Engine
A straight-four engine (also referred to as an inline-four engine) is a four-cylinder Reciprocating engine, piston engine where cylinders are arranged in a line along a common crankshaft. The 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-4 engine, 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 ...

Peugeot 305
The Peugeot 305 is a medium-sized car produced by the French automaker Peugeot from 1977 to 1989. It was offered as a four-door saloon, five-door estate, and as a three-door van derivative. History Origins During the mid 1970s, the motoring press speculated that a new Peugeot would soon arrive, in order to update the company's model lineup, in an attempt to make the Peugeot more internationally appealing. Since Peugeot had only recently discontinued their long-running 404 model, many people thought that the purpose of the new car would to fill the gap, previously occupied by the 404, between the 304 and 504 models, to compete against cars like the Ford Cortina/Taunus and Renault 12. It therefore would have been natural for the new car to be called the 405, commencing a new "05" generation of Peugeot models. However, in fact the car was developed from the running gear from the 304, but in terms of size and price, it was close to the already-defunct 404. The 304 would remain in pr ...

Carburettor
A carburetor (also spelled carburettor or carburetter) is a device used by a gasoline internal combustion engine to control and mix air and fuel entering the engine. The primary method of adding fuel to the intake air is through the Venturi effect or Bernoulli's principle or with a Pitot tube in the main metering circuit, though various other components are also used to provide extra fuel or air in specific circumstances. Since the 1990s, carburetors have been largely replaced by fuel injection for cars and trucks, but carburetors are still used by some small engines (e.g. lawnmowers, generators, and concrete mixers) and motorcycles. In addition, they are still widely used on piston-engine–driven aircraft. Diesel engines have always used fuel injection instead of carburetors, as the compression-based combustion of diesel requires the greater precision and pressure of fuel injection. Etymology The term ''carburetor'' is derived from the verb ''carburet'', which means ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Citroën Visa
The Citroën Visa is a five-door, front-engine, front wheel drive supermini car, supermini manufactured and marketed by Citroën from 1978 to 1988 in gasoline and diesel variants. 1,254,390 examples were ultimately manufactured over a single generation, with a single Facelift (automotive), facelift (1981). China has also assembled the car as the Liuzhou Wuling LZW 7100 minicar. Production started in 1991 and finished in 1994. Citroën commissioned Heuliez to produce a Visa convertible variant, marketed as the ''Décapotable'' (1984), and a box van variant (1985–2005) was marketed as the Citroën C15. A sedan variant was prototyped but never manufactured. Development In 1965 Robert Opron began working on the Citroën G-mini prototype and project EN101, a replacement for the 2CV using its flat twin engine and intended to launch in 1970. The advanced space efficient designs with compact exterior dimensions and an aerodynamic drag co-efficient Cd of 0.32, were never fully ...

Peugeot 205
The Peugeot 205 is a four-passenger, front-engine, supermini ( B-segment) car manufactured and marketed by Peugeot over a sixteen-year production run from 1983 to 1999, over a single generation. Developed from ''Projet'' M24 and introduced on 25 February 1983, the 205 replaced the Peugeot 104 and the Talbot Samba, using major elements from their design. It won '' What Car?'' Car of the Year for 1984. It was also declared "car of the decade" by CAR Magazine in 1990. Peugeot stopped marketing the 205 in 1999 in favor of its new front-engined 206. The 106, which was introduced in 1991, effectively took over as Peugeot's smaller front-engined model in their lineup. The latter was developed as a close sibling of the Citroën AX, sharing many components and a platform that later evolved into the Citroën Saxo. History Before the 205, Peugeot was considered the most conservative of France's "big three" car manufacturers, producing large saloons such as the 504 and 505, altho ...

Fuel Injection
Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of a fuel injector. This article focuses on fuel injection in reciprocating piston and Wankel rotary engines. All compression-ignition engines (e.g. diesel engines), and many spark-ignition engines (i.e. petrol (gasoline) engines, such as Otto or Wankel), use fuel injection of one kind or another. Mass-produced diesel engines for passenger cars (such as the Mercedes-Benz OM 138) became available in the late 1930s and early 1940s, being the first fuel-injected engines for passenger car use. In passenger car petrol engines, fuel injection was introduced in the early 1950s and gradually gained prevalence until it had largely replaced carburetors by the early 1990s. The primary difference between carburetion and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while carburetion relies on suction crea ...

Stroke (engine)
In the context of an internal combustion engine, the term stroke has the following related meanings: * A phase of the engine's cycle (e.g. compression stroke, exhaust stroke), during which the piston travels from top to bottom or vice versa. * The type of power cycle used by a piston engine (e.g. two-stroke engine, four-stroke engine). * "Stroke length", the distance travelled by the piston during each cycle. The stroke length, along with bore diameter, determines the engine's displacement. Phases in the power cycle Commonly used engine phases or strokes (i.e. those used in a four-stroke engine) are described below. Other types of engines can have very different phases. Induction-intake stroke The induction stroke is the first phase in a four-stroke (e.g. Otto cycle or Diesel cycle) engine. It involves the downward movement of the piston, creating a partial vacuum that draws an air-fuel mixture (or air alone, in the case of a direct injection engine) into the combustion ...

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] |
Citroën ZX
The Citroën ZX is a Compact car, small family car produced by the French manufacturer Citroën between 1991 and 1998. At the beginning of the 1990s, the ZX was Citroën's entry in the class traditionally dominated in Europe by the Ford Escort (European), Ford Escort and Vauxhall Astra, Vauxhall/Opel Astra, a market segment Citroën had briefly abandoned with the demise of the Citroën GS, GSA in 1986. The Citroën BX, BX had tried to address the small family car market and the large family car market by being "between sizes" but well packaged. For 1993, the Citroën ZX chassis was also used for the Peugeot 306 which, with its attractive Peugeot 205 derived styling, was an even more successful car than its twin. The Citroën Berlingo and Peugeot Partner were also built on the front half of the same platform, the rear coming from the 405, an arrangement shared underneath the Xsara Picasso. It was replaced by the Citroën Xsara, Xsara in September 1997, but production in Europe co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Citroën BX
The Citroën BX is a large family car which was produced by the French manufacturer Citroën from 1982 to 1994. In total, 2,315,739 BXs were built during its 12-year history. The hatchback was discontinued in 1993 with the arrival of the Xantia, but the estate continued for another year. The BX was designed to be lightweight, using particularly few body parts, including many made from plastics. History The Citroën BX was announced in June 1982, but its commercial life really only began in the Autumn of that year, with a Paris presentation on 2 October 1982 under the Eiffel Tower. The BX was designed to replace the successful small family car Citroën GS/GSA that was launched in 1970, with a larger vehicle (although the GSA continued until 1986). The French advertising campaign used the slogan "J'aime, j'aime, j'aime" showing the car accompanied by music written specially by Julien Clerc. The British advertising campaign used the slogan "Loves Driving, Hates Garages", reflec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cylinder Liner
In an engine, the cylinder is the space in which a piston travels. The inner surface of the cylinder is formed from either a thin metallic liner (also called "sleeve") or a surface coating applied to the engine block. A piston is seated inside each cylinder by several metal piston rings, which also provide seals for compression and the lubricating oil. The piston rings do not actually touch the cylinder walls, instead they ride on a thin layer of lubricating oil. Steam engines The cylinder in a steam engine is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were cast in cast iron and later in steel. The cylinder casting can include other features such as valve ports and mounting feet. Internal combustion engines The cylinder is the space through which the piston travels, propelled by the energy generated from the combustion of the air/fuel mixture in the combustion chamber. In an air-cooled engine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Front Wheel Drive
Front-wheel drive (FWD) is a form of internal combustion engine, engine and transmission (mechanics), transmission layout used in motor vehicles, in which the engine drives the front wheels only. Most modern front-wheel-drive vehicles feature a transverse engine, rather than the conventional longitudinal engine arrangement generally found in automobile layout#Rear wheel drive layouts, rear-wheel-drive and four-wheel drive, four-wheel-drive vehicles. Location of engine and transmission By far the most common layout for a front-wheel-drive car is with the engine and transmission at the front of the car, mounted transversely. Other layouts of front-wheel drive that have been occasionally produced are a front-engine mounted longitudinally, a mid-engine layout and a rear-engine layout. History Prior to 1900 Experiments with front-wheel-drive cars date to the early days of the automobile. The world's first self-propelled vehicle, Nicolas-Joseph Cugnot's 1769/1770 Nicola ...
