BMW N63
The BMW N63 is a twin-turbocharged petrol V8 engine which has been in production from 2008 to present. The N63 is the world's first production car engine to use a "hot-vee" layout, with the turbochargers located inside the "V" of the engine. It is also BMW's first turbocharged petrol V8 engine. The engine has been widely noted for its mechanical issues, undergoing several recalls. The N63 replaced the BMW N62 (a naturally aspirated V8 engine) and was first used in the 2008 X6 xDrive50i. The S63 engine is the BMW M high-performance version of the N63. Alpina versions of the N63 are used in various F01 7 Series, F10 5 Series, G11 7 Series, G15 8 Series and G30 5 Series models. Design The airflow path through the engine uses a "hot-vee" layout, where the exhaust manifolds and turbochargers are located between the cylinder banks (on the "inside" of the V8) and the intake manifolds are located on the outside of the engine. This is opposite to the traditional layout for a V8 ...

V8 Engine
A V8 engine is an eight- cylinder piston engine in which two banks of four cylinders share a common crankshaft and are arranged in a V configuration. Origins The first known V8 was the Antoinette, designed by Léon Levavasseur, and built in 1904 by the French Antoinette company for use in speedboat racing, cars, and later, airplanes. Also in 1904, V8 engines began small-scale production by Renault and Buchet for use in race cars. Design V-angle Most engines use a V-angle (the angle between the two banks of cylinders) of 90 degrees. This angle results in good engine balance, which results in low vibrations. However, the downside is the greater width of the engine compared to those that use a smaller V-angle. V8 engines with a 60-degree V-angle were used in the 1996–1999 Ford Taurus SHO, the 2005–2011 Volvo XC90, and the 2006–2009 Volvo S80. The Ford engine used a 60-degree V-angle because it was based on a V6 engine with a 60-degree V-angle. ...

BMW 6-Series
The BMW 6 Series is a range of grand tourers produced by BMW since 1976. It is the successor to the E9 Coupé and is currently in its fourth generation. The first generation BMW E24 6 Series was available solely as a two-door coupé and produced from 1976 to 1989, when it was supplanted by the larger BMW 8 Series (E31). When the 6 Series nameplate was revived in 2004 for the second generation, the BMW E63/E64 6 Series, the coupé was joined by a convertible body style. The third generation F06/F12/F13 6 Series debuted in 2011 as a coupé and convertible, and a sedan variant known as the "Gran Coupé" in 2012. When the F06/F12/F13 6 Series ended production, the "Gran Coupé"/coupé/convertible models have been shifted into the more upmarket BMW 8 Series (G15) nameplate. The fourth generation 6 Series, the G32 6 Series, debuted in mid-2017 and is offered only as a fastback body style to complement the BMW 5 Series (G30) sedan/wagon. The first generation 6 Series was derived fr ...

Powerband
The power band of an internal combustion engine or electric motor is the range of operating speeds under which the engine or motor is able to output the most power, that is, the maximum energy per unit of time. This usually means that maximum acceleration can be achieved inside this band (often at the cost of lower efficiency). While engines and motors have a large range of operating speeds, the power band is usually a much smaller range of engine speed, only half or less of the total engine speed range (electric motors are an exception—see the section on electric motors below). Specifically, power band is the range of RPM around peak power output. The power band of an internal combustion gasoline automobile engine typically starts at midrange engine speeds (around 4,000 RPM) where maximum torque is produced, and ends below the redline after reaching maximum power (typically between 6,200 RPM and 6,800 RPM). Diesel engines in cars and small trucks may develop maximum torque ...

Turbocharger
In an internal combustion engine, a turbocharger (also known as a turbo or a turbosupercharger) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake air, forcing more air into the engine in order to produce more power for a given displacement.
Turbochargers are distinguished from superchargers in that a turbocharger is powered by the kinetic energy of the exhaust gases, whereas a is mechanically powered (usually by a belt from the engine's crankshaft). However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger.

Blowoff Valve
A blowoff valve (also called dump valve or compressor bypass valve) is a pressure release system present in most petrol turbocharged engines. Blowoff valves are used to reduce pressure in the intake system as the throttle is closed, thus preventing compressor surge. Design A key function of blowoff valves is to prevent compressor surge, a phenomenon that would otherwise occur as the throttle is closed in a turbocharged engine. If the turbocharger's compressor wheel is spinning at high speed when the throttle is suddenly closed (such as during a gear change), the flow reduces beyond the surge line of the compressor. At this point the change in pressure across the compressor reduces, leading to a collapse in flow and possibly even flow reversal and a collapse in plenum pressure. As the compressor is still spinning at high speed, once the flow has reduced sufficiently, the change in pressure across the compressor begins to rise and flow is re-established into the plenum. This rap ...

Stroke (engine)
In the context of an internal combustion engine, the term stroke has the following related meanings: * A phase of the engine's cycle (e.g. compression stroke, exhaust stroke), during which the piston travels from top to bottom or vice versa. * The type of power cycle used by a piston engine (e.g. two-stroke engine, four-stroke engine). * "Stroke length", the distance travelled by the piston during each cycle. The stroke length, along with bore diameter, determines the engine's displacement. Phases in the power cycle Commonly used engine phases or strokes (i.e. those used in a four-stroke engine) are described below. Other types of engines can have very different phases. Induction-intake stroke The induction stroke is the first phase in a four-stroke (e.g. Otto cycle or Diesel cycle) engine. It involves the downward movement of the piston, creating a partial vacuum that draws an air-fuel mixture (or air alone, in the case of a direct injection engine) into the combustion ...

Bore (engine)
In a piston engine, the bore (or cylinder bore) is the diameter of each cylinder. Engine displacement is calculated based on bore, stroke length and the number of cylinders: displacement = The stroke ratio, determined by dividing the bore by the stroke, traditionally indicated whether an engine was designed for power at high engine speeds ( rpm) or torque at lower engine speeds. The term "bore" can also be applied to the bore of a locomotive cylinder or steam engine pistons. In steam locomotives The term bore also applies to the cylinder of a steam locomotive or steam engine. Bore pitch Bore pitch is the distance between the centerline of a cylinder bore to the centerline of the next cylinder bore adjacent to it in an internal combustion engine. It's also referred to as the "mean cylinder width", "bore spacing", "bore center distance" and "cylinder spacing". The bore pitch is always larger than the inside diameter of the cylinder (the bore and piston diameter) sinc ...

Gasoline Direct Injection
Gasoline direct injection (GDI), also known as petrol direct injection (PDI), is a fuel injection system for internal combustion engines that run on gasoline (petrol) which injects fuel directly into the combustion chamber. This is distinct from manifold injection systems, which inject fuel into the intake manifold (inlet manifold) where it mixes with the incoming airstream before reaching the combustion chamber.. The use of GDI can help increase engine efficiency and specific power output as well as reduce exhaust emissions. The first GDI engine to reach production was introduced in 1925 for a low-compression truck engine. Several German cars used a Bosch mechanical GDI system in the 1950s, however usage of the technology remained rare until an electronic GDI system was introduced in 1996 by Mitsubishi for mass-produced cars. GDI has seen rapid adoption by the automotive industry in recent years, increasing in the United States from 2.3% of production for model year 2008 ...
