BMW M52
The BMW M52 is a straight-6 DOHC petrol engine which was produced from 1994 to 2000. It was released in the E36 320i, to replace the M50. The BMW S52 engine is a high performance variant of the M52 which powered the American and Canadian market E36 M3 from 1996 to 1999. In 1998, the "technical update" (M52TU) upgrades included adding variable valve timing to the exhaust camshaft. The M52 was replaced by the M54 in the year 2000. The M52 and S52 engines were on the Ward's 10 Best Engines list from 1997 to 2000. Design In most markets, the M52 switched from the M50's cast iron engine block to a lightweight aluminium engine block. However, most M52 engines produced for the United States and Canadian markets (except for those used by the BMW Z3 roadster) retained the M50's cast iron engine block, while other cars used the new aluminum M52 block with iron sleeves. The largest version of the M52 is 2.8 litres, compared with 2.5 litres for the M50. As per the later versi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Straight-six Engine
The straight-six engine (also referred to as an inline-six engine; abbreviated I6 or L6) 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 less cylinders. Until the mid-20th century, the straight-six layout was the most common design for engines with six cylinders. However, V6 engines became more common from the 1960s and by the 2000s most straight-six engines had been replaced by V6 engines. An exception to this trend is BMW which has produced automotive straight-six engines from 1933 to the present day. Characteristics In terms of packaging, straight-six engines are almost always narrower than a V6 engine or V8 engine, but longer than straight-four engines, V6s, and most V8s. Straight-six engines are typically produced in displacements ranging from , however engines ranging in size from the Benelli 750 ...

BMW E36
The third generation of the BMW 3 Series range of compact executive cars is designated under the model code E36, and was produced by the German automaker BMW from 1990 to 2000. The initial models were of the four-door sedan body style, followed by the coupe, convertible, wagon ("Touring"), hatchback ("Compact"), and the rare four-door convertible Baur TC4 in later years. The E36 was the first 3 Series to be offered in a hatchback body style. It was also the first 3 Series to be available with a six-speed manual transmission (in the 1996 M3), a five-speed automatic transmission, and a four-cylinder diesel engine. The multi-link rear suspension was also a significant upgrade as compared to the previous generations of the 3 Series. Unlike the previous (E30) and successive (E46) generations, all-wheel drive was not available for the E36. The E36 was named in ''Car and Driver'' magazine's 10Best list for every year it was on sale. Following the introduction of its successor, the ...

BMW Engines
BMW has been producing engines for automobiles, motorcycles and aircraft since 1917, when the company began production of an inline-six aircraft engine. They have been producing automobile engines since 1933. Motorcycle engines Automotive petrol engines BMW is well known for its history of inline-six (straight-six) engines, a layout it continues to use to this day despite most other manufacturers switching to a V6 layout. The more common inline-four and V8 layouts are also produced by BMW, and at times the company has produced inline-three, V10 and V12 engines, BMW also engineered non production customised engines especially for motorsports which includes M12/13, 1.5-Liter straight 4 piston turbocharged engine from 1982-1987 for Brabham, Arrows and Benetton Formula One teams, E41/P83, 3.0-Liter V10 from 2000-2005 for Williams F1 Team and P86/8, 2.4-Liter V8 for their own F1 team parterning Sauber F1 from 2006-2009, with which the company enjoyed its first and bes ...

BMW S54
The BMW M54 is a naturally aspirated straight-6 petrol engine produced from 2000 to 2006. It was released in the E53 X5 and is the replacement for the M52 engine. The S54 is the equivalent high performance engine, used in the E46 M3, the Z3 M Coupé/Roadster and the E85/E86 Z4 M. The BMW M56 SULEV engine (sold in several states of the United States) is based on the M54. The M54 was phased out following the introduction of the BMW N52 engine in 2004. From 2001 to 2003, the M54 was included on the Ward's 10 Best Engines list. Design Compared with the final versions of its M52 predecessor (called the 'M52TU'), the M54 has a non-return fuel system, a fully electronic throttle (without mechanical backup), Siemens MS 43 engine management, a revised intake manifold. The displacement of the largest variant increased from 2.8 L to , due to an increase in stroke to . As per the M52TU, the M54 uses an aluminium block and aluminium cylinder head with cast iron cylinder liners. Variab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BMW S50
The BMW M50 is a straight-6 DOHC petrol engine which was produced from 1990 to 1996. It was released in the E34 520i and 525i, to replace the M20 engine. In September 1992, the M50 was upgraded to the M50TU ("technical update"), which was BMW's first engine to use variable valve timing. Called single VANOS by BMW, the system adjusted the phasing of the intake camshaft. The M50 began to be phased out following the introduction of the M52 engine in 1994. The E36 M3 is powered by the S50 engine series, which is a high output version of the M50. Design A significant advance over its M20 predecessor, the M50 features dual overhead camshaft (DOHC) with four valves per cylinder (the M20 has a single overhead camshaft with 2 valves per cylinder), coil-on-plug ignition, a knock sensor and a lightweight plastic intake manifold. Both engines use an iron block with an aluminum alloy head. The redline is 6,500 rpm for the M50B25 and 6,750 rpm for the M50B20 (7,000&nbs ...

Nikasil
Nikasil is a trademarked electrodeposited lipophilic nickel matrix silicon carbide coating for engine components, mainly piston engine cylinder liners. Development Nikasil was introduced by Mahle in 1967, and initially developed to allow Wankel engine apex seals (NSU Ro 80, Citroën GS Birotor and Mercedes C111) to work directly against the aluminium housing. This coating allowed aluminium cylinders and pistons to work directly against each other with low wear and friction. Unlike other methods, including cast iron cylinder liners, Nikasil allowed very large cylinder bores with tight tolerances. This made it possible for existing engine designs to be expanded easily. The aluminium cylinders also gave a much better heat conductivity than cast iron liners, an important attribute for a high-output engine. The coating was further developed as a replacement for hard-chrome plated cylinder bores for Mercury Marine Racing, Kohler Engines, and as a repair replacement for factory-chrome ...

BMW 7-Series
The BMW 7 Series is a full-size luxury sedan manufactured and marketed by the German automaker BMW since 1977. It is the successor to the BMW E3 "New Six" sedan and is now in its seventh generation. The 7 Series is BMW's flagship car and is only available in a sedan bodystyle (including long wheelbase and limousine models). It traditionally introduces technologies and exterior design themes before other models in BMW's lineup. The first generation of the 7 Series was powered by straight-6 petrol engines, and following generations have been powered by inline-4, straight-6, V8 and V12 engines with both natural aspiration and turbocharging. Since 1995, diesel engines have been optional in the 7 Series. Unlike the 3 Series and 5 Series sedans, BMW has offered a nonpureblood M variant, the BMW M760 6.6L V12 (at the time the most powerful BMW ever made, not to be confused with BMW 760 6.6 V12 which does not offer the same performance). The Alpina B7 (G12) serves as one of the hig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Land Rover Defender
The Land Rover Defender (initially introduced as the Land Rover 110 / One Ten, and in 1984 joined by the Land Rover 90 / Ninety, plus the new, extra-length Land Rover 127 in 1985) is a series of British off-road cars and pickup trucks. They consistently have four-wheel drive, and were developed in the 1980s from the original Land Rover series which was launched at the Amsterdam Motor Show in April 1948. Following the 1989 introduction of the Land Rover Discovery, the term 'Land Rover' became the name of a broader marque, and thus no longer worked as the name of a specific model; thus in 1990 Land Rover renamed the 90 and 110 as Defender 90 and Defender 110 respectively. The 127 became the Defender 130. The vehicle, a British equivalent of the Second World War derived (Willys) Jeep, gained a worldwide reputation for ruggedness and versatility. Using a steel ladder chassis and an aluminium alloy bodywork, the Land Rover originally used detuned versions of Rover engines. The ...

BMW E38
The BMW Generation E38 is the third generation of the BMW 7 Series luxury cars and was produced from 1994 until 2001. The E38 replaced the E32 7 Series and was produced with petrol and turbo-diesel straight-six and V8 engines, along with a petrol V12 flagship model. Three wheelbase lengths were available — short (i), long (iL) and Limousine (L7). The E38 was the first car available with curtain airbags. It was also the first European car to offer satellite navigation and the first BMW to offer an in-built television. The E38 was the first 7 Series to be available with a diesel engine and the last to be available with a manual transmission. In 2001, the E38 was replaced by the E65 7 Series. Development In early 1988, development began on the third generation of the 7 Series. From 1988 to 1990 styling work was done initially under design director Claus Luthe (through April 1990, taken over by Dr. Wolfgang Reitzle), when Boyke Boyer's concept design was chosen and furthe ...

Revolutions Per Minute
Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or with the notation min−1) is a unit of rotational speed or rotational frequency for rotating machines. Standards ISO 80000-3:2019 defines a unit of rotation as the dimensionless unit equal to 1, which it refers to as a revolution, but does not define the revolution as a unit. It defines a unit of rotational frequency equal to s−1. The superseded standard ISO 80000-3:2006 did however state with reference to the unit name 'one', symbol '1', that "The special name revolution, symbol r, for this unit is widely used in specifications on rotating machines." The International System of Units (SI) does not recognize rpm as a unit, and defines the unit of frequency, Hz, as equal to s−1. :\begin 1~&\text &&=& 60~&\text \\ \frac~&\text &&=& 1~&\text \end A corresponding but distinct quantity for describing rotation is angular velocity, for which the SI unit is the ra ...

BMW E46
The fourth generation of the BMW 3 Series range of compact executive cars is designated under the model code E46, which was produced by the German automaker BMW from 1997 to 2006, and was the successor to the E36 3 Series which ceased production in 2000. First introduced in November 1997, the E46 was available in sedan, coupé, convertible, station wagon and hatchback body styles. The latter has been marketed as the 3 Series Compact. The M3 performance model was introduced in June 2000 with a 2-door coupé body style, followed by the convertible counterpart in April 2001. The M3 is powered by the BMW S54 straight-six engine with either a 6-speed manual or a 6-speed SMG-II automated manual transmission. The E46 line-up was phased out starting from late 2004, following the introduction of the E90 3 Series sedans. However, the E46 coupé and convertible body styles remained in production until August 2006. Overview Development In 1993, the development programme for the ...
