BMW M70
The BMW M70 is a naturally-aspirated, SOHC, V12 petrol engine, which was BMW's first production V12 and was produced from 1987 to 1996. The BMW S70/2 engine, largely unrelated to the M70 and S70B56 engines, is a naturally-aspirated, DOHC, V12 petrol engine, which powered the 1993 to 1998 McLaren F1. Design The M70's design is similar to that of two 2.5 L M20 straight-six engines joined at a 60 degree angle, due to the following features: single overhead camshaft valvetrain, bore spacing of , bore of , stroke of , and a compression ratio of 8.8:1. The M70 has the following differences with the M20 engine: * Aluminium alloy engine block ( AluSil) instead of cast-iron (both engines have an aluminium cylinder head), to reduce weight. * Airflow measurement using Mass air flow sensors (MAFs) instead of Air flow meters (AFMs) to improve fuel economy. * Electronic Throttle Control instead of a mechanical throttle cable. * A timing chain was used instead of a timing belt, to reduc ...

V12 Engine
A V12 engine is a twelve-cylinder piston engine where two banks of six cylinders are arranged in a V configuration around a common crankshaft. V12 engines are more common than V10 engines. However, they are less common than V8 engines. The first V12 engine was built in 1904 for use in racing boats. Due to the balanced nature of the engine and the smooth delivery of power, V12 engines were found in early luxury automobiles, boats, aircraft, and tanks. Aircraft V12 engines reached their apogee during World War II, following which they were mostly replaced by jet engines. In Formula One racing, V12 engines were common during the late 1960s and early 1990s. Applications of V12 engines in the 21st century have been as marine engines, in railway locomotives, as large stationary power as well as in some European sports and luxury cars. Design Balance and smoothness Each bank of a V12 engine essentially functions as a straight-six engine, which by itself has perfect primary a ...

Timing Belt (camshaft)
In a piston engine, either a timing belt (also called a ''cambelt'') or timing chain or set of timing gears is used to synchronize the rotation of the crankshaft and the camshaft. This synchronisation ensures that the engine's valves open and close at the correct times in relation to the position of the pistons. Design In most piston engines, the camshaft(s) are mechanically connected to the crankshaft. The crankshaft drives the camshaft (via a timing belt, timing chain or pushrods), which in turn actuates the intake and exhaust valves. These valves allow the engine to inhale air (or an air/fuel mixture) and exhale the exhaust gasses. The most common devices to transfer the drive are toothed rubber belts, metal timing chains or a set of gears. The teeth of the belt/chain/gears mesh with both the crankshaft and camshaft(s), thereby synchronising their motion. In many older overhead valve engines, the camshaft is located in the block near the crankshaft, therefore a simple ...

Water Cooling
Cooling tower and water discharge of a nuclear power plant Water cooling is a method of heat removal from components and industrial equipment. Evaporative cooling using water is often more efficient than air cooling. Water is inexpensive and non-toxic; however, it can contain impurities and cause corrosion. Water cooling is commonly used for cooling automobile internal combustion engines and power stations. Water coolers utilising convective heat transfer are used inside high-end personal computers to lower the temperature of CPUs. Other uses include the cooling of lubricant oil in pumps; for cooling purposes in heat exchangers; for cooling buildings in HVAC and in chillers. Mechanism Advantages Water is inexpensive, non-toxic, and available over most of the earth's surface. Liquid cooling offers higher thermal conductivity than air cooling. Water has unusually high specific heat capacity among commonly available liquids at room temperature and atmospheric pressure allowi ...

BMW 8 Series (E31)
The BMW E31 is the first generation of the BMW 8 Series. It is a grand tourer built by BMW from 1990 to 1999 as a 2-door coupé, powered by either a V8 or V12 engine. Whilst it did supplant the original E24 based 6 Series in 1990, it was not a direct successor, but a new model class with a substantially higher price and performance than the 6 Series. Development Development of the 8 Series began in July 1981, with both the final design phase reaching completion in 1986, although the launch was delayed due to still-strong 6 Series sales. The 8 Series debuted at the Frankfurt Motor Show (IAA) in early September 1989. The 8 Series was designed to move beyond the market of the original 6 Series. The 8 Series had substantially improved performance, as well as a far higher purchase price. Over 1.5 billion Deutsche Marks were spent on total development (2019 USD nearly $900 million). BMW used CAD tools, still unusual at the time, to design the car's all-new body. Combined with ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

BMW 7 Series (E32)
The BMW E32 is the second generation of the BMW 7 Series luxury cars and was produced from 1986 until 1994. It replaced the E23 and was initially available with straight-six or V12 powerplants. In 1992, V8 engines became available. From its inception, the E32 was among the most technologically advanced series of cars in its day. The E32 introduced numerous features including adaptive suspension (EDC), traction control, two available wheelbases (i and iL), and dual-zone climate control. The E32 750i was the first car adhering to "gentlemen's agreement" amongst the German manufacturers limiting maximum speed to . Other automotive passenger vehicles features introduced with the E32 included: projector lens headlamps (1986); double glazing windows (1991); HID (Xenon) headlamps (1991).
