BMW N52
The BMW N52 is a naturally aspirated straight-six petrol engine which was produced from 2004 to 2015. The N52 replaced the BMW M54 and debuted on the E90 3 Series and E63 6 Series. The N52 was the first water-cooled engine to use magnesium/aluminium composite construction in the engine block. It was also listed as one of Ward's 10 Best Engines in 2006 and 2007. In European markets, the N52 began to be phased out following the release of the BMW N53 in 2007. However, in markets such as the United States, Canada, Australia and Malaysia, the N53 was deemed unsuitable due to the high levels of sulfur in the fuel. From the year 2011, the N52 began to be replaced by the BMW N20 turbocharged four-cylinder engine until production of the N52 finished in 2015. Unlike its predecessors, there is no BMW M version of the N52. __TOC__ Design Compared with its M54 predecessor, the N52 features Valvetronic (variable valve lift), a lighter block due to the use of a magnesium alloy and ...

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 However, V6 engines became more common from the 1960s and by the 2000s most straight-six engines had been replaced by V6 engines.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 ...

Variable Intake
In internal combustion engines, a variable-length intake manifold (VLIM),variable intake manifold (VIM), or variable intake system (VIS) is an automobile internal combustion engine manifold technology. As the name implies, VLIM/VIM/VIS can vary the length of the intake tract - in order to optimise power and torque across the range of engine speed operation, as well as help provide better fuel efficiency. This effect is often achieved by having two separate intake ports, each controlled by a valve, that open two different manifolds - one with a short path that operates at full engine load, and another with a significantly longer path that operates at lower load. The first patent issued for a variable length intake manifold was published in 1958, US Patent US2835235 by Daimler Benz AG. There are two main effects of variable intake geometry: ;Swirl: Variable geometry can create a beneficial air swirl pattern, or turbulence in the combustion chamber. The swirling helps distribute th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BMW Z4 (E85)
The first generation of the BMW Z4 consists of the BMW E85 (roadster version) and BMW E86 (coupe version) sports cars. The E85/E86 generation was produced from 2002 to 2008. The E85/E86 replaced the Z3 and is the third model in the BMW Z Series. Initial models were in the roadster (E85) body style, with the coupé (E86) body style being added in 2006. In February 2009, the BMW Z4 (E89) began production as the successor to the E85/E86. As per the Z3, the E85/E86 was manufactured solely in Greer, South Carolina. The M model, the Z4 M, is powered by the S54 straight-six engine. Development and launch The E85 was designed by Danish BMW-designer Anders Warming from mid-1998 to the summer of 1999. The coupe models were designed by Tomasz Sycha. The E85 designs were frozen on March 1, 2000. The Z4 was introduced at the Paris Motor Show in 2002, and North American models went on sale in November of the same year (as the 2003 model year). European sales began in March 2003. Ini ...

BMW E60
The fifth generation of the BMW 5 Series executive cars consists of the BMW E60 (sedan version) and BMW E61 (wagon version, marketed as 'Touring'). The E60/E61 generation was produced by BMW from 2003 to 2010 and is often collectively referred to as the E60. The E60 generation introduced various new electronic features, including the iDrive infotainment system, head-up display, active cruise control, active steering, adaptive headlights, night vision, lane departure warning and voice control. The E60 was the first 5 Series to be available with a turbocharged petrol engine, a 6-speed automatic transmission and regenerative braking. The M5 model was introduced in 2005 and is powered by the BMW S85 V10 engine. It was sold in the sedan and wagon body styles, with most cars using the 7-speed SMG III transmission. It was the first and only M5 model to be sold with a V10 engine. In January 2010, the BMW 5 Series (F10) began production as the successor to the E60. Development and l ...

BMW E90
The fifth generation of the BMW 3 Series range of compact executive cars is designated under the model codes E90 (saloon), E91 (estate, marketed as 'Touring'), E92 (coupé) and E93 (convertible). The model was introduced in December 2004, and produced by BMW until October 2013 and is often collectively referred to as the E90 or E9x. The E9x saw the introduction of run-flat tyres to the 3 Series range. Models with run-flat tires are not equipped with a spare tyre. The E92 335i was the first 3 Series model produced with a turbocharged petrol engine. It was also the first 3 Series to include the iDrive operating system, which consists of navigation, infotainment and essential vehicle functions. The E90/E92/E93 M3 is the only generation of M3 to be powered by a V8 engine. Introduced in 2007, it uses the BMW S65 naturally aspirated V8 engine and was produced in saloon, coupé and convertible body styles. Following the introduction of the F30/F31 3 Series in February 2012, the E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
