BMW X3
The BMW X3 is a compact luxury crossover SUV manufactured by BMW since 2003, based on the BMW 3 Series platform. Now in its third generation, BMW markets the car as a ''Sports Activity Vehicle'', the company's proprietary descriptor for its X-line luxury vehicles. The first-generation X3 was designed by BMW in conjunction with Magna Steyr of Graz, Austria—who also manufactured all X3s under contract to BMW. BMW manufactured the second-generation X3 at their Spartanburg plant in South Carolina, United States. The third generation of the BMW X3 is manufactured at BMW South Africa's Rosslyn plant, a facility that underwent a major upgrade to prepare for the X3 production, replacing the long-running 3 Series production in the plant. About 76,000 units will be manufactured there annually. The car was the first mid-size, premium SUV on the market. In 2008, BMW started competing with the Mercedes-Benz GLK-Class (renamed GLC-Class since 2016), and numerous other SUVs in this segm ...

Compact Crossover SUV
Compact crossover SUV is an automobile classification used mainly in North America to describe a segment of crossover SUV, a type of sport utility vehicle, between subcompact crossover SUV and mid-size crossover SUV. By late 2010s, the segment has emerged as the most popular automobile segment in several regions. For example, nearly 1 in every 4 cars sold in the United States in 2019 is a compact crossover, precisely at about 24.2 percent. The best-selling vehicle in the segment in 2020 was the Toyota RAV4, with 995,762 units sold globally. It is also the second best-selling automobile in the world after the Toyota Corolla. Terminology The term "compact crossover SUV" is most commonly used in the North America, where the "compact car" and "crossover" terms originated from. It is also known as C-segment SUV or C-SUV. The naming of the segment also differ depending on the market. In several regions outside North America, the category may be known as "mid-size/medium crossover" o ...

Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...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 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 ...

BMW M54
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. Varia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inline-four Engine
A straight-four engine (also called an inline-four) is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. The vast 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 stroke occu ...

BMW N46
The BMW N46 is a naturally aspirated inline-four piston engines which replaced the BMW N42 and was produced from 2004 to 2015. The N46 serves as the basis for the smaller BMW N45 engine (which does not have Valvetronic). In 2007, the N46's successor - the BMW N43 - was introduced. However, the direct-injected N43 was not sold in countries with high-sulfur fuel, so the N46 continued to be produced alongside the N43. The N46 continued production until 2015, when the last N46 models were replaced by the BMW N13 turbocharged four-cylinder engine. Design Compared with its N42 predecessor, the N46 features a revised crankshaft, intake manifold and valvetrain. In 2007, the N46 was updated, which was known as the N46N. Changes included the intake manifold, exhaust camshaft and the engine control unit was changed from Bosch Motronic version ME9.2 to version MV17.4.6. The redline is 6,500 rpm. Versions N46B18 The N46B18 has a displacement and produces and . Applicati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petrol Engine
A petrol engine (gasoline engine in American English) is an internal combustion engine designed to run on petrol (gasoline). Petrol engines can often be adapted to also run on fuels such as liquefied petroleum gas and ethanol blends (such as ''E10'' and ''E85''). Most petrol engines use spark ignition, unlike diesel engines which typically use compression ignition. Another key difference to diesel engines is that petrol engines typically have a lower compression ratio. Design Thermodynamic cycle Most petrol engines use either the four-stroke Otto cycle or the two-stroke cycle. Petrol engines have also been produced using the Miller cycle and Atkinson cycle. Layout Most petrol-powered piston engines are straight engines or V engines. However, flat engines, W engines and other layouts are sometimes used. Wankel engines are classified by the number of rotors used. Compression ratio Cooling Petrol engines are either air-cooled or water-cooled. Ignition Petrol e ...

Four-wheel Drive
Four-wheel drive, also called 4×4 ("four by four") or 4WD, refers to a two-axled vehicle drivetrain capable of providing torque to all of its wheels simultaneously. It may be full-time or on-demand, and is typically linked via a transfer case providing an additional output drive shaft and, in many instances, additional gear ranges. A four-wheel drive vehicle with torque supplied to both axles is described as "all-wheel drive" (AWD). However, "four-wheel drive" typically refers to a set of specific components and functions, and intended off-road application, which generally complies with modern use of the terminology. Definitions Four-wheel-drive systems were developed in many different markets and used in many different vehicle platforms. There is no universally accepted set of terminology that describes the various architectures and functions. The terms used by various manufacturers often reflect marketing rather than engineering considerations or significant technical diff ...
