Alusil
Alusil as a hypereutectic aluminium-silicon alloy (EN AC-AlSi17Cu4Mg / EN AC-48100 or A390) contains approximately 78% aluminium and 17% silicon. This alloy was theoretically conceived in 1927 by Schweizer & Fehrenbach, of the Badener Metall-Waren-Fabrik, 2a Hermannstraße, Baden-Baden; but practically created only by Lancia in the same year, for its car engines. It was further developed by Kolbenschmidt. The Alusil aluminium alloy is commonly used to make linerless aluminium alloy engine blocks. Alusil, when etched, will expose a very hard silicon precipitate. The silicon surface is non-porous enough to hold oil, and is an excellent bearing surface. BMW switched from Nikasil-coated cylinder walls to Alusil in 1996 to eliminate the corrosion problems caused through the use of petrol/gasoline containing sulfur. Engines using Alusil include: *Audi 2.4 V6 *Audi 4.2 MPI V8 *Audi 3.2 FSI V6 *Audi 4.2 FSI V8 *Audi 5.2 FSI V10 *Audi/Volkswagen 6.0 W12 *BMW M52 I6 *BMW M54 I6 ...

List Of Volkswagen Group Petrol Engines
The spark-ignition petrol engines listed below operate on the four-stroke cycle, and unless stated otherwise, use a wet sump lubrication system, and are water-cooled.ETKA official factory data Since the Volkswagen Group is German, official internal combustion engine performance ratings are published using the International System of Units (commonly abbreviated "SI"), a modern form of the metric system of figures. Motor vehicle engines will have been tested by a Deutsches Institut für Normung (DIN) accredited testing facility, to either the original '' 80/1269/EEC'', or the later ''1999/99/ EC'' standards. The standard initial measuring unit for establishing the rated motive power output is the kilowatt (kW); and in their official literature, the power rating may be published in either the kW, or the metric horsepower (often abbreviated "PS" for the German word ''Pferdestärke''), or both, and may also include conversions to imperial units such as the horsepower (hp) or bra ...

BMW M62
BMW M62 is a naturally aspirated V8 petrol engine which was produced from 1995 to 2005. A successor to the BMW M60, the M62 features an aluminium engine block and a single row timing chain. In 1998, a Technical Update included VANOS (variable valve timing) for the intake camshafts. The S62 engine is the BMW M high performance version of the M62, which was released in the E39 M5, BMW Z8, Ascari KZ1, and the Ascari A10. Design Like the BMW M60 engine it replaced, the M62 is a DOHC engine with four valves per cylinder, an aluminum block and aluminum heads. The M62 has fracture-split forged connecting rods, hypereutectic pistons with ferrous coated side skirts. Most of the M62 engines used Alusil for the block material, however some early M62 engines used Nikasil cylinder coating instead. Alusil technology integrates silicon throughout the aluminum cast so that liners or treated bores within this block family are not needed. The M62 uses a Bosch Motronic 5.2 engine control u ...

Nikasil
Nikasil is a trademarked electrodeposited lipophilic nickel matrix silicon carbide coating for engine components, mainly piston engine cylinder liners. Development Nikasil was introduced by Mahle in 1967, and initially developed to allow Wankel engine apex seals (NSU Ro 80, Citroën GS Birotor and Mercedes C111) to work directly against the aluminium housing. This coating allowed aluminium cylinders and pistons to work directly against each other with low wear and friction. Unlike other methods, including cast iron cylinder liners, Nikasil allowed very large cylinder bores with tight tolerances. This made it possible for existing engine designs to be expanded easily. The aluminium cylinders also gave a much better heat conductivity than cast iron liners, an important attribute for a high-output engine. The coating was further developed as a replacement for hard-chrome plated cylinder bores for Mercury Marine Racing, Kohler Engines, and as a repair replacement for factory-chrome ...

Mercedes-Benz M112 Engine
The Mercedes-Benz M112 engine is a gasoline-fueled, 4-stroke, spark-ignition, internal-combustion automobile piston V6 engine family used in the 2000s. Introduced in 1998, it was the first V6 engine ever built by Mercedes. A short time later the related M113 V8 was introduced. All are built in Bad Cannstatt, Germany except the supercharged C32 AMG, which is assembled in Affalterbach, Germany. All M112 engines have silicon/aluminum (Alusil) engine blocks with a 90° vee angle. The aluminum SOHC cylinder heads have 3 valves per cylinder. All use sequential fuel injection with two spark plugs per cylinder. All have forged steel connecting rods, a one-piece cast camshaft, iron-coated aluminum pistons and a magnesium intake manifold. To deal with the vibration problems of a 90 degree V6, a balancer shaft was installed in the engine block between the cylinder banks. This essentially eliminated first and second order vibration problems (see engine balance). A dual-length Variable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 reduce s ...

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. The first V8 engine was produced by the French Antoinette company in 1904, developed and used in cars and speedboats but primarily aircraft; while the American 1914–1935 ''Cadillac L-Head'' engine is considered the first road going V8 engine to be mass produced in significant quantities. The popularity of V8 engines in cars was greatly increased following the 1932 introduction of the ''Ford Flathead V8''. In the early 21st century, use of V8 engines in passenger vehicles declined as automobile manufacturers opted for more fuel efficient, lower capacity engines, or hybrid and electric drivetrains. Design V-angle The majority of V8 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 a larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BMW N62
The BMW N62 is a naturally aspirated V8 petrol engine which was used in BMW cars from 2001–2010. It also remained in small-scale production for the Morgan Aero until 2019. The N62 is the world's first engine to use a continuously variable-length intake manifold, and BMW's first V8 to feature variable valve lift (called Valvetronic). Unlike its predecessor and successor, there was no M version of the N62. In the International Engine of the Year awards in 2002, the N62 was awarded "International Engine of the Year", "Best New Engine" and "Above 4-litre" categories. Design The N62 was a clean sheet design and not a direct evolution of the M60 engine line that evolved into the M62 engine. The N62 has a bore of and stroke of for a total displacement of 4,398cc and features double-VANOS variable valve timing on both the intake and exhaust camshafts (the M62 features variable valve timing on only the intake camshaft). As per the M62, the N62 has double overhead camshafts ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eutectic System
A eutectic system or eutectic mixture ( ) is a homogeneous mixture that has a melting point lower than those of the constituents. The lowest possible melting point over all of the mixing ratios of the constituents is called the ''eutectic temperature''. On a phase diagram, the eutectic temperature is seen as the eutectic point (see plot on the right). Non-eutectic mixture ratios would have different melting temperatures for their different constituents, since one component's lattice will melt at a lower temperature than the other's. Conversely, as a non-eutectic mixture cools down, each of its components would solidify (form a lattice) at a different temperature, until the entire mass is solid. Not all binary alloys have eutectic points, since the valence electrons of the component species are not always compatible, in any mixing ratio, to form a new type of joint crystal lattice. For example, in the silver-gold system the melt temperature ( liquidus) and freeze temperature (s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
