Rover K-Series Engine
The Rover K-series engine is a series of internal combustion engines built by Powertrain Ltd, a sister company of MG Rover. The engine was a straight-four cylinder built in two forms, SOHC and DOHC, ranging from . Design history The K series was introduced in 1988 by Rover Group as a powerplant for the Rover 200 car. It was the second volume-production implementation of the low-pressure sand-casting (or LPS) technique in a new plant sited between East Works and Cofton Hackett. (The first volume application of the LPS process had been for the M-16 cylinder head, produced in South Works, adjacent to the former forge). The LPS process pumped liquid aluminium into a chemically-bonded sand mould from below. This reduced oxide inclusions and gave a casting yield of around 90%, compared with 60% for more conventional gravity casting processes. The process avoided many of the inherent problems of casting aluminium components and consequently permitted lower casting wall thickness ...

Rover Group
The Rover Group plc was the British vehicle manufacturing conglomerate known as "BL plc" until 1986 (formerly British Leyland), which had been a state-owned company since 1975. It initially included the Austin Rover Group car business (comprising the Austin, Rover, Mini and MG marques), Land Rover Group, Freight Rover vans and Leyland Trucks. The Rover Group also owned the dormant trademarks from the many companies that had merged into British Leyland and its predecessors such as Triumph, Morris, Wolseley, Riley and Alvis. The Rover Group was owned by British Aerospace (BAe) from 1988 to 1994. In 1994, BAe sold the remaining car business of Rover Group plc to the German company BMW. The group was then broken up in 2000, when Ford acquired the Land Rover division, with the Rover and MG marques continuing with the much smaller MG Rover Group until 2005. Ownership of the original Rover Group marques is currently split between BMW (Germany), SAIC (China), and Tata Motors (In ...

Single Overhead Cam
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] |
Chesterfield, Derbyshire
Chesterfield is a market town and unparished area in the Borough of Chesterfield, Derbyshire, England, north of Derby and south of Sheffield at the confluence of the River Rother and River Hipper. In 2011 the built-up-area subdivision had a population of 88,483, making it the second-largest settlement in Derbyshire, after Derby. The wider borough had a population of 103,801 in 2011. In 2011, the town had a population of 76,753. It has been traced to a transitory Roman fort of the 1st century CE. The name of the later Anglo-Saxon village comes from the Old English ''ceaster'' (Roman fort) and ''feld'' (pasture). It has a sizeable street market three days a week. The town sits on an old coalfield, but little visual evidence of mining remains. The main landmark is the crooked spire of the Church of St Mary and All Saints. History Chesterfield was in the Hundred of Scarsdale. The town received its market charter in 1204 from King John, which constituted the town as a free b ...

Cylinder Liner
In a reciprocating 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 to the energy generated from the combustion of the air/fuel mixture in the combustion chamber. In an air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centrifugal Casting (industrial)
Centrifugal casting or rotocasting is a casting technique that is typically used to cast thin-walled cylinders. It is typically used to cast materials such as metals, glass, and concrete. A high quality is attainable by control of metallurgy and crystal structure. Unlike most other casting techniques, centrifugal casting is chiefly used to manufacture rotationally symmetric stock materials in standard sizes for further machining, rather than shaped parts tailored to a particular end-use. Materials Typical materials that can be centrifugal cast are metals, cements, concretes, glass, and pottery materials. Typical metals cast are iron, steel, stainless steels, and alloys of nickel, aluminum, and copper, magnesium. Two materials can be combined by introducing a second material during the process. A common example is cast iron pipe coated on the interior with cement. Process for casting metal In centrifugal casting, a permanent mold is rotated continuously at high speeds (300 t ...

Rover M-series Engine
The Rover M series (or M16) is a line of 4-cylinder, DOHC internal-combustion engine introduced by the Austin Rover Group in 1986 for the then-new Rover 800 series. The M series was produced only in one cubic capacity – 1994 cc (2.0 L), and was a 16 valve development of the older British Leyland O-series unit first seen in 1978. For the Rover 800, there were two different versions, with single point fuel injection (for the Rover 820e) or multi-point injection (for the 820i). The M series uses the same cylinder block as the O-series unit as found in the Maestro and Montego, which mates with the Powertrain Ltd PG-1 manual gearbox. These were also used in the Morgan Plus Four, the only rear wheel drive application this engine was used in, meaning these can be put in rear wheel drive layouts using the Rover LT77 transmission In 1990, the M series was also installed in the Rover 200 series The Rover 200 Series, and later the Rover 25, are a series of small family cars tha ...

Cofton Hackett
Cofton Hackett is a village and civil parish in the Bromsgrove District of north east Worcestershire, England. It is southwest of the city centre of Birmingham and northeast of Worcester. In 2011, the village had a population of 1,893 but with housing development on the former Austin Rover site, this is expected to double over the five years to 2023. The village is served by two main bus services, these being the 20 (Cofton Hackett – Queen Elizabeth Hospital) and 145/145A ( Longbridge – Droitwich) operated by National Express and Diamond Bus respectively. History Early history Cofton Hackett is an ancient settlement mentioned in historical documents dating back to 780 AD. ''Coſtune'' (Costune) was among places granted by King Offa to the minster of St Peter, Bredon in 780. The bounds for this estate probably covered the parishes of Alvechurch and Cofton. The spelling of the name has varied over the centuries: for many centuries, the usual spelling was Coston. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rover 200 / 25
The Rover 200 Series, and later the Rover 25, are a series of small family cars that were produced by British manufacturer Rover from 1984 until 2005. There have been three distinct generations of the Rover 200. The first generation was a four-door saloon car based on the Honda Ballade. The second generation was available in three or five-door hatchback forms, as well a coupé and cabriolet (in relatively small numbers). Its sister model, the Honda Concerto was built on the same production line in Rover's Longbridge factory. The final generation was developed independently by Rover on the platform of its predecessor, and was available as a three or five-door hatchback. Just before BMW's sale of Rover in 2000, and following a facelift, the model was renamed and sold as the Rover 25, and the MG ZR was based on the Rover 25 with mechanical changes to the suspension. Production ceased in 2005 when MG Rover went into administration. Production rights and tooling for the model, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...
