The straight-six engine is a piston engine with six cylinders arranged in a straight line along the crankshaft. A straight-six engine has perfect primary and secondary engine balance, resulting in fewer vibrations than other designs of six or fewer cylinders.
British Leyland was a British automotive engineering and manufacturing conglomerate formed 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% 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.
The Princess is a large family car produced in the United Kingdom by the Austin-Morris division of British Leyland from 1975 until 1981. The car inherited a front-wheel drive / transverse engine configuration from its predecessor, the Austin/Morris 1800 range. This was still unusual in Europe for family cars of this type and gave the Princess a cabin space advantage when compared with similarly sized cars from competing manufacturers.
The Metro is a supermini car, later a city car that was produced from 1980 to 1998, first by British Leyland (BL) and later by the Rover Group. It was launched in 1980 as the Austin Mini Metro.
The Rover 800 series is an executive car 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/Acura Legend and the successor to the decade-old Rover SD1.
Coventry Climax was a British manufacturer of forklift trucks, fire pumps, racing engines, and other speciality engines.
The General Motors LS-based small-block engines are a family of V8 and offshoot V6 engines designed and manufactured by the American automotive company General Motors. First introduced in 1997, the family is a continuation of the earlier first- and second-generation Chevrolet small-block engine, of which over 100 million have been produced altogether and is also considered one of the most popular V8 engines ever. Spanning three generations, a new, sixth generation is expected to enter production soon. Various small-block V8s were and still are available as crate engines.
The Chevrolet Stovebolt engine is a straight-six engine made in two versions between 1929 and 1962 by the Chevrolet Division of General Motors. It replaced the company's 171-cubic-inch (2.8 L) inline-four as their sole engine offering from 1929 through 1954, and was the company's base engine starting in 1955 when it added the small block V8 to the lineup. It was completely phased out in North America by 1962, but GM continued to build it in Brazil until 1979. It was replaced by the Chevrolet Turbo-Thrift engine.
The Rover V8 engine is a compact OHV V8 internal combustion engine with aluminium cylinder block and cylinder heads, designed and produced by Rover in the United Kingdom, based on a General Motors engine. It has been used in a wide range of vehicles from Rover and other manufacturers since its British debut in 1967.
The Rover SD1 is both the code name and eventual production name given to a series of executive cars built by the Specialist Division, and finally the Austin Rover division of British Leyland from 1976 until 1986, when it was replaced by the Rover 800. The SD1 was marketed under various names. In 1977 it won the European Car of the Year title.
A multi-valve or multivalve engine is one where each cylinder has more than two valves. A multi-valve engine has better breathing, and with more smaller valves may be able to operate at higher revolutions per minute (RPM) than a two-valve engine, delivering more power.
The Austin Motor Company A-series is a British small straight-4 automobile engine. Launched in 1951 with the Austin A30, production lasted until 2000 in the Mini. It used a cast-iron block and cylinder head, and a steel crankshaft with three main bearings. The camshaft ran in the cylinder block, driven by a single-row chain for most applications, and with tappets sliding in the block, accessible through pressed steel side covers for most applications, and with overhead valves operated through rockers. The cylinder blocks are not interchangeable between versions intended for conventional end-on mounted gearboxes and the 'in-sump' transaxle used on British Motor Corporation/British Leyland front wheel drive models such as the Mini. The cylinder head for the overhead-valve version of the A-series engine was designed by Harry Weslake – a cylinder head specialist famed for his involvement in SS (Jaguar) engines and several Formula One-title winning engines. Although a "clean sheet" design, the A-series owed much to established Austin engine design practise, resembling in general design and overall appearance a scaled-down version of the 1200cc overhead-valve engine first seen in the Austin A40 Devon which would form the basis of the later B-series engine.
The BMC B series is a line of straight-4 & straight-6 internal combustion engine mostly used in motor cars, created by British automotive manufacturer Austin Motor Company.
The MGB is a two-door sports car manufactured and marketed from 1962 until 1980 by the British Motor Corporation (BMC), later the Austin-Morris division of British Leyland, as a four-cylinder, soft-top sports car. It was announced and its details first published on 19 September 1962. Variants include the MGB GT three-door 2+2 coupé (1965–1980), the six-cylinder sports car and coupé MGC (1967–1969), and the eight-cylinder 2+2 coupé, the MGB GT V8 (1973–1976).
The BMC C-Series is a straight-6 automobile engine produced from 1954 to 1971. Unlike the Austin-designed A-Series and B-Series engines, it came from the Morris Engines drawing office in Coventry and therefore differed significantly in its layout and design from the two other designs which were closely related. This was due to the C-Series being in essence an enlarged overhead valve development of the earlier 2.2 L Straight-6 overhead camshaft engine used in the post-war Morris Six MS and Wolseley 6/80 from 1948 until 1954, which itself also formed the basis of a related 1.5 L 4-cylinder engine for the Morris Oxford MO in side-valve form and the Wolseley 4/50 in overhead camshaft form. Displacement was 2.6 to 2.9 L with an undersquare stroke of 88.9 mm (3.50 in), bored out to increase capacity.
The BMC E-series engine is a line of straight-4 and straight-6 overhead camshaft automobile petrol engines from the British Motor Corporation (BMC). It displaced 1.5 L or 1.8 L in four-cylinder form, and 2.2 L or 2.6 L as a six-cylinder. The company's native United Kingdom market did not use the 2.6 L version, which was used in vehicles of Australian and South African manufacture. Although designed when the parent company was BMC, by the time the engine was launched the company had become British Leyland (BL), and so the engine is commonly referred to as the British Leyland E-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.
The Triumph Six Cylinder or Triumph I6 engine is a cast-iron overhead valve straight-six engine produced by Standard Triumph. It is an evolution of the Standard Motor Company's inline-4 Standard Eight, with the addition of two cylinders and a larger displacement.
The Austin Drawing Office was the design and engineering department of the British Motor Corporation. From the early 1950s, the resulting projects of the office were known by the initials ADO. The numbers were assigned to vehicle and engineering projects, some resulting in production models. The ADO numbering system continued well beyond BMC's absorption into British Leyland, who continued to use the convention until the late 1970s.
The Standard SC engine is a cast-iron overhead valve straight-four engine designed and initially produced by Standard Triumph. Over its production life displacement grew from an initial size of just over 800 cc to nearly 1500 cc. Introduced in the Standard Eight in 1953, it would eventually be used in a wide range of vehicles from Standard, Triumph, and MG.
