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using the Rover LT77 transmission In 1990, the M series was also installed in the Rover 200 series, before being superseded in 1992 by the similar T series which was a development of the ...

DOHC
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] |
Internal-combustion Engine
An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons (piston engine), turbine blades (gas turbine), a rotor (Wankel engine), or a nozzle (jet engine). This force moves the component over a distance, transforming chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to. This replaced the external combustion engine for applications where the weight or size of an engine was more important. The first commercially successful internal combustion engine was created by Étienne Lenoir around 1860, and the first modern internal combustion engine, known as th ...

Austin Rover Group
The Austin Rover Group (abbreviated ARG) was a British motor manufacturer. It was created in 1982 as the mass-market car manufacturing subsidiary of British Leyland (BL). Previously, this entity had been known as BL Cars Ltd (formerly Leyland Cars) which encompassed the ''Austin-Morris'' and ''Jaguar-Rover-Triumph'' divisions of British Leyland. After a major restructuring of BL's car manufacturing operations, Jaguar regained its independence (leading to its eventual de-merger in 1984) whilst the Triumph and Morris marques were retired. The new, leaner car business was rechristened as the Austin Rover Group and focused primarily on the Austin and Rover marques. The Morris and Triumph marques continued briefly within ARG until 1984 when both were dropped. In 1989, two years after the Austin brand was also discontinued, ARG assumed the name of its parent company ''Rover Group plc'', from which point the two entities were generally considered one and the same, although they con ...

Rover 800
The Rover 800 series is an executive car (E-segment in Europe) range manufactured by the Austin Rover Group subsidiary of British Leyland, and its successor the Rover Group from 1986 to 1999. It was also marketed as the Sterling in the United States. Co-developed with Honda, it was a close relative to the Honda Legend and the successor to the decade-old Rover SD1. Development Partnership with Honda The first product of the BL-Honda alliance was the Triumph Acclaim – and shortly after its launch the two companies mapped out an advisable strategy for future collaborative projects. Plans for a midsize car were investigated, but were dropped because BL already had the Austin Maestro and Austin Montego in the final stages of development. However both BL and Honda had a pressing need for a full-size executive car in their lineups. BL had to start planning for a successor to the Rover SD1, whilst Honda was keen to expand its presence in the lucrative North American market – somethi ...

16 Valve
In automotive engineering a multi-valve or multivalve engine is one where each cylinder has more than two valves. A multi-valve engine has better breathing and may be able to operate at higher revolutions per minute (RPM) than a two-valve engine, delivering more power. Multi-valve rationale Multi-valve engine design A multi-valve engine design has three, four, or five valves per cylinder to achieve improved performance. Any four-stroke internal combustion engine needs at least two valves per cylinder: one for ''intake'' of air (and often fuel), and another for ''exhaust'' of combustion gases. Adding more valves increases valve area and improves the flow of intake and exhaust gases, thereby enhancing combustion, volumetric efficiency, and power output. Multi-valve geometry allows the spark plug to be ideally located within the combustion chamber for optimal flame propagation. Multi-valve engines tend to have smaller valves that have lower reciprocating mass, which can red ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Leyland
British Leyland was an automotive engineering and manufacturing conglomerate formed in the United Kingdom in 1968 as British Leyland Motor Corporation Ltd (BLMC), following the merger of Leyland Motors and British Motor Holdings. It was partly nationalised in 1975, when the UK government created a holding company called British Leyland, later renamed BL in 1978. It incorporated much of the British-owned motor vehicle industry, which in 1968 had a 40 percent share of the UK car market, with its history going back to 1895. Despite containing profitable marques such as Jaguar, Rover and Land Rover, as well as the best-selling Mini, BLMC had a troubled history, leading to its eventual collapse in 1975 and subsequent part-nationalisation. After much restructuring and divestment of subsidiary companies, BL was renamed the Rover Group in 1986, becoming a subsidiary of British Aerospace from 1988 to 1994, then was subsequently bought by BMW. The final surviving incarnation of the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuel Injection
Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of an 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 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 carburettors 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 a carburettor relies on suction created by intake ai ...

Cylinder Block
In an internal combustion engine, the engine block is the structure which contains the cylinders and other components. In an early automotive engine, the engine block consisted of just the cylinder block, to which a separate crankcase was attached. Modern engine blocks typically have the crankcase integrated with the cylinder block as a single component. Engine blocks often also include elements such as coolant passages and oil galleries. The term "cylinder block" is often used interchangeably with "engine block", although technically, the block of a modern engine (i.e. multiple cylinders integrated with another component) would be classified as a monobloc. __TOC__ Construction The main structure of an engine typically consists of the cylinders, coolant passages, oil galleries, crankcase, and cylinder head(s). The first production engines of the 1880s to 1920s usually used separate components for each of these elements, which were bolted together during engine assembly. M ...

Austin Maestro
The Austin Maestro is a five-door hatchback small family car (and two-door van derivative) that was produced from 1982 to 1987 by British Leyland, and from 1988 until 1994 by Rover Group, as a replacement for the Morris Marina and Austin Allegro. The car was produced at Morris' former Oxford plant, also known as Cowley, with 605,000 units sold. Today, the redeveloped factory builds the BMW Mini. An MG-branded performance version was sold as the MG Maestro from 1983 until 1991. Although later models were sometimes referred to as the Rover Maestro, the model never wore the Rover badge. The Austin Montego saloon was a variant of the Maestro. Background British Leyland was created in 1975 when the bankrupt British Leyland Motor Corporation was nationalised. In 1977 the South African-born corporate troubleshooter, Michael Edwardes, was recruited as chairman to sort out the troubled firm. Part of Edwardes' plan was to introduce a completely new range of mass-market models to re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Austin Montego
The Austin Montego is a British family car that was produced by British Leyland from 1984 until 1988, and then by Rover Group from 1988 until 1995. The Montego was the replacement for both the rear-wheel drive Morris Ital and the front-wheel drive Austin Ambassador ranges to give British Leyland an all-new competitor for the Ford Sierra and Vauxhall Cavalier. On its launch, it was sold as both an Austin and an MG. It was the last car to be launched under the Austin marque, and from 1988 it was sold without a marque, following the phasing out of the Austin name. Design and development The Montego started life as a four-door notchback variant of project LC10. Development on the new model, intended to succeed both the Morris Marina and the Princess ranges by the turn of the 1980s, had begun in 1977 but ultimately the new car was not launched until seven years after development had started; in the meantime, the Marina had been updated and rebadged as the Morris Ital from 1980, whil ...
