Rover K 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 ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BL O-series Engine
The BL O-series engine is an automobile straight-four engine family that was produced by the Austin-Morris division of British Leyland (BL) as a development of the BMC B-series engine family. (See also another B-series successor, the BMC E-series engine.) Introduced by BL in 1978 in the rear wheel drive Series 3 Morris Marina and the smaller engined versions of the front-wheel-drive Princess, it was intended to replace the 1.8 L B-series unit. The main advance over the B series was that the new unit was of belt driven overhead camshaft configuration, with an aluminium cylinder head. Design Offered in the unusual capacity of 1.7 L as well as 2.0 L, it proved to be reliable and was widely used in BL vehicles. These included the rear wheel drive Morris Ital of 1980 (1.7 L or 2.0 L with an automatic gear box), the rear wheel drive Rover SD1 of 1982 (2.0 L only), and 1.7 L and 2.0 L in the front wheel drive Austin Ambassador – in fact ...

Single Overhead Cam
An overhead camshaft (OHC) engine is a piston engine in which 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 O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chesterfield, Derbyshire
Chesterfield is a market town, market and industrial town in the county of Derbyshire, England. It is north of Derby and south of Sheffield at the confluence of the River Rother, South Yorkshire, Rivers Rother and River Hipper, 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 of Chesterfield had a population of 103,569 in the 2021 Census. In 2021, the town itself had a population of 76,402. It has been traced to a transitory Ancient Roman architecture, Roman fort dated to approximately AD 80-100. The name of the later Anglo-Saxons, 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 since the closure of the final town centre mine nicknamed “The Green Room”. The main landmark is the crooked sp ...

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] |
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 rotational symmetry, rotationally symmetric stock materials semi-finished casting products, 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 alloys, nickel, aluminum alloys, aluminum, and copper alloys, 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 cas ...

Rover 200 / 25
The Rover 200 Series, and later the Rover 25, are a series of small family cars that were produced by former 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Inline-four Engine
A straight-four engine (also referred to as an inline-four engine) is a four-cylinder 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-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 st ...
