BMW X3
The BMW X3 is an SUV manufactured by BMW since 2003, based on the BMW 3 Series platform. 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 BMW US Manufacturing Company, Spartanburg plant in South Carolina, United States. Starting with the third generation, BMW South Africa's Rosslyn plant began production of the X3, alongside the Spartanburg plant, after the facility 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 Mercedes-Benz GLC-Class, GLC-Class since ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compact Luxury Crossover SUV
A crossover, crossover SUV, or crossover utility vehicle (CUV) is a type of automobile with an increased ride height that is built on unibody chassis construction shared with passenger cars, as opposed to traditional sport utility vehicles ( SUVs), which are built on a body-on-frame chassis construction similar to pickup trucks. A term that originated from North America, the term crossover was initially used for any vehicle that blends characteristics between two different kinds of vehicles while, over time, crossover predominantly refers to unibody-based SUVs. The term SUV is often used as an umbrella term for both crossovers and traditional SUVs due to the similarities between them. Compared to traditional SUVs, crossovers are known to be less capable of use in off-road conditions or hauling heavy loads while offering other advantages such as improved fuel economy and handling. Compared to traditional cars with lower ride height and lower roofs such as sedans and hatchbac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Diesel Engine
The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which Combustion, ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to Mechanics, mechanical Compression (physics), compression; thus, the diesel engine is called a 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). Introduction Diesel engines work by compressing only air, or air combined with 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 air temperature inside the Cylinder (engine), cylinder so that atomised diesel fuel injected into the combustion chamber ignites. The torque a dies ...

Straight-six Engine
A 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 fewer cylinders. Until the mid-20th century, the straight-six layout was the most common design for engines with six cylinders. However, V6 engines gradually became more common in the 1970s and by the 2000s, V6 engines had replaced straight-six engines in most light automotive applications. 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. Compared to V-configuration engines with similar power and displacement, the straight configuration has fewer injectors, a single head, and a single exhaust manifold, all contributing to better reliability and perfor ...

BMW N52
The BMW N52 is a Naturally aspirated engine, naturally aspirated Straight-six engine, straight-6 petrol engine which was produced from 2004 to 2015. The N52 replaced the BMW M54 and debuted on the BMW 3 Series (E90), E90 3 Series and BMW 6 Series (E63), 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 in favor of its direct injected version, the BMW N53 in 2007. Markets such as the United States, Canada, Australia and Malaysia retained the N52 as the N53 was deemed unsuitable due to the high sulphur content of local fuel. The engine is equipped with a dual overhead cam 24 valve cylinder head and the crankshaft is held in place with 36 main bearing cap bolts. The static compression ratio is 12.5:1 advertised, requiring the use of 100 RON (94 AKI) fuel. The N52 and N53 are the l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BMW M54
The BMW M54 is a naturally aspirated straight-6 DOHC 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. Design Compared with the final versions of its M52 predecessor (called the 'M52TÜ'), the M54 has a non-return fuel system, a fully electronic throttle (without mechanical backup), Siemens MS 43 engine management, and 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 M52TÜ, the M54 uses an aluminium block and aluminium cylinder head with cast iron cylinder liners ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inline-four Engine
A straight-four engine (also referred to as an inline-four engine) is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. The 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 st ...

BMW N46
The BMW N46 is a naturally aspirated inline-four piston engine 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 . Applicatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petrol Engine
A petrol engine (gasoline engine in American and Canadian 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''). They may be designed to run on petrol with a higher octane rating, as sold at petrol stations. Most petrol engines use spark ignition, unlike diesel engines which run on diesel fuel and typically use compression ignition. Another key difference to diesel engines is that petrol engines typically have a lower compression ratio. History The first practical petrol engine was built in 1876 in Germany by Nicolaus August Otto and Eugen Langen, although there had been earlier attempts by Étienne Lenoir in 1860, Siegfried Marcus in 1864 and George Brayton in 1873. Design Thermodynamic cycle Most petrol engines use either the four-stroke Otto cycle or the two-stroke cycle. Petrol engines have also ...

Four-wheel Drive
A four-wheel drive, also called 4×4 ("four by four") or 4WD, is 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 diffe ...

Front-engine, Four-wheel-drive Layout
In automotive design, an F4, or front-engine, four-wheel drive (4WD) layout places the internal combustion engine at the front of the vehicle and drives all four roadwheels. This car layout, layout is typically chosen for better control on many surfaces, and is an important part of rallying, rally racing, as well as off-roading, off-road driving. In terms of racing purposes, whether it be on-road or off-road, can be described as follows, A team that pursues the Weak LS4WD architecture will minimize the development cost of the front-wheel drive system at the expense of having a larger rear powertrain. The Weak architecture produces a vehicle with a large powersplit between the front and rear powertrains, while the Strong architecture recommends a vehicle with more similar power and torque requirements for the front and rear. Most four-wheel-drive layouts are front-engined and are derivatives of earlier Front-engine, rear-wheel-drive layout, front-engine, rear-wheel drive, or Fr ...
