BMW E38
The BMW 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 succeeded 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 further refined ...

BMW M57
The BMW M57 is a straight-6 diesel engine produced from 1998 up to 2013 in BMW's Upper Austrian engine plant in Steyr. Description The M57 is a water-cooled and turbocharged inline six cylinder diesel engine with common rail injection. It was revised twice during its production time. It is based on its predecessor M51. The block and the crankcase of the first M57 engines and the TÜ (''Technische Überarbeitung'' = revision) engines are made of cast iron, whilst the TÜ2 engines are made of aluminium instead. The combustion chamber was also changed in the TÜ2. The injection pressure is in the non TÜ engine, whilst all other engines use a pressure of . For fuel injection, magnetic injectors are used, except from the TÜ2 OL and TOP engines, which make use of piezo injectors. The common-rail-system is made by Bosch and also controlled by a Bosch DDE 4 ECU for non TÜ and DDE 5 ECU for TÜ. All models are equipped with turbocharger and an intercooler. The 2.9L M57, which is fo ... [...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 ...

Automotive Navigation System
An automotive navigation system is part of the automobile controls or a third party add-on used to find direction in an automobile. It typically uses a satellite navigation device to get its position data which is then correlated to a position on a road. When directions are needed routing can be calculated. On the fly traffic information (road closures, congestion) can be used to adjust the route. Dead reckoning using distance data from sensors attached to the Powertrain, drivetrain, an accelerometer, a Inertial guidance system#Vibrating gyros, gyroscope, and a magnetometer can be used for greater reliability, as GNSS signal loss and/or Multipath propagation, multipath can occur due to urban canyons or tunnels. Mathematically, automotive navigation is based on the shortest path problem, within graph theory, which examines how to identify the path that best meets some criteria (shortest, cheapest, fastest, etc.) between two points in a large network. Automotive navigation systems ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airbag
An airbag is a vehicle occupant-restraint system using a bag designed to inflate in milliseconds during a collision and then deflate afterwards. It consists of an airbag cushion, a flexible fabric bag, an inflation module, and an impact sensor. The purpose of the airbag is to provide a vehicle occupant with soft cushioning and restraint during a collision. It can reduce injuries between the flailing occupant and the vehicle's interior. The airbag provides an energy-absorbing surface between the vehicle's occupants and a steering wheel, instrument panel, body pillar, headliner, and windshield. Modern vehicles may contain up to ten airbag modules in various configurations, including driver, passenger, side-curtain, seat-mounted, door-mounted, B- and C-pillar mounted side-impact, knee bolster, inflatable seat belt, and pedestrian airbag modules. During a crash, the vehicle's crash sensors provide crucial information to the airbag electronic controller unit (ECU), including colli ...

Wheelbase
In both road and rail vehicles, the wheelbase is the horizontal distance between the centers of the front and rear wheels. For road vehicles with more than two axles (e.g. some trucks), the wheelbase is the distance between the steering (front) axle and the centerpoint of the driving axle group. In the case of a tri-axle truck, the wheelbase would be the distance between the steering axle and a point midway between the two rear axles. Vehicles The wheelbase of a vehicle equals the distance between its front and rear wheels. At equilibrium, the total torque of the forces acting on a vehicle is zero. Therefore, the wheelbase is related to the force on each pair of tires by the following formula: :F_f = mg :F_r = mg where F_f is the force on the front tires, F_r is the force on the rear tires, L is the wheelbase, d_r is the distance from the center of mass (CM) to the rear wheels, d_f is the distance from the center of mass to the front wheels (d_f + d_r = L), m is the mass ...

BMW 7 Series (E65)
The fourth generation of the BMW 7 Series consists of the BMW E65 and BMW E66 luxury cars. The E65/E66 was produced from 2001 to 2008 and is often collectively referred to as the E65. The E65 replaced the BMW 7 Series (E38), E38 7 Series and was produced with petrol and turbo-diesel straight-six and V8 engines, along with a petrol V12 flagship model. The E65 was the first BMW vehicle to include the iDrive infotainment system, and the exterior styling (overseen by Chris Bangle) marked a significant departure from traditional BMW styling. Other new features included active anti-roll bars, a six-speed automatic transmission, an electronic ''Smart Key'' (dispensing with the traditional metallic key), and night vision. The 760i model also utilised the world's first production V12 engine to use direct injection. In late 2008, the E65 7 Series was replaced by the BMW 7 Series (F01), F01 7 Series. Development and launch Development for the BMW E65 7 Series began in early 1996. In earl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alpina B12
The Alpina B12 is a name given to high-performance luxury automobiles manufactured by German automobile manufacturer Alpina. The B12 originally succeeded the B11 4.0 in 1988 which was based on the BMW 7 Series (E32) and was also based on the same car. Subsequent models were based on the BMW 7 Series (E38) and the BMW 8 Series (E31). Production ended in 2001 when the 7 Series (E38) models were discontinued. The B12 was replaced by the B7 (E65) and the B6 (E63). 406 t93d 406 B12 5.0 (E32) The B12 5.0 was introduced in 1988 and was the first Alpina production automobile to use a V12 engine as its predecessor, the B11 used 3.5 and 4.0 L V8 engines. The suffix 5.0 means the engine displacement which was unchanged from the standard BMW M70 V12. The B12 5.0 was based on the newly introduced 750i/iL. Exterior changes include a front chin spoiler, 17-inch multi-spoke alloy wheels, choice of special colours, "B12 5.0" badge at the rear, and Alpina pinstriping. The interior was cu ...

Automatic Transmission
An automatic transmission (AT) or automatic gearbox is a multi-speed transmission (mechanics), transmission used in motor vehicles that does not require any input from the driver to change forward gears under normal driving conditions. The 1904 Sturtevant "horseless carriage gearbox" is often considered to be the first true automatic transmission. The first mass-produced automatic transmission is the General Motors ''Hydramatic'' two-speed hydraulic automatic, which was introduced in 1939. Automatic transmissions are especially prevalent in vehicular drivetrains, particularly those subject to intense mechanical acceleration and frequent idle/transient operating conditions; commonly commercial/passenger/utility vehicles, such as buses and waste collection vehicles. Prevalence Vehicles with internal combustion engines, unlike electric vehicles, require the engine to operate in a narrow range of rates of rotation, requiring a gearbox, operated manually or automatically, to drive t ...

Manual Transmission
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canadian English, Canada, British English, the United Kingdom and American English, the United States), or stick shift (in the United States), is a multi-speed motor vehicle Transmission (mechanical device), transmission system where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually a foot pedal for cars or a hand lever for motorcycles). Early automobiles used ''sliding-mesh'' manual transmissions with up to three forward gear ratios. Since the 1950s, ''constant-mesh'' manual transmissions have become increasingly commonplace, and the number of forward ratios has increased to 5-speed and 6-speed manual transmissions for current vehicles. The alternative to a manual transmission is an automatic transmission. Common types of automatic transmissions are the Automatic transmission#Hydraulic automatic transmissions, hydraulic automatic ...
