BMW M60
The BMW M60 is a naturally aspirated V8 petrol engine which was produced from 1992 to 1996. It was BMW's first V8 engine in over 25 years. The M60 was replaced by the BMW M62 engine. Development During the 1970s, BMW produced a prototype V8 engine for the E23 7 Series, however this engine did not reach production. Development of the M60 began in 1984. Design The M60 engine has double overhead camshafts with four valves per cylinder. The camshaft is driven by a dual-row timing chain with a self-adjusting tensioner. Valves had hydraulic lash adjustment to reduce maintenance. The ignition and fuel injection systems are controlled by the Bosch Motronic 3.3 system, and the ignition system is a coil-on-plug design with knock sensors. To reduce weight, the engine uses aluminum for both the engine block and cylinder head, magnesium valve covers and a plastic intake manifold. The M60 was BMW's first car engine to use a "split conrod" design, where sintered connecting rods are made ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
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. A BMW M high performance version of the M62, called the S62 engine, was fitted to BMW's E39 M5 and BMW Z8, and both the Ascari KZ1 and 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 engin ...

BMW OHV V8 Engine
The BMW OHV V8 is an overhead valve V8 petrol engine produced from 1954 to 1965. It is BMW's first V8 engine, and BMW did not produce another V8 automobile engine until the BMW M60 in 1992. The engine does not have an official model code, therefore it is often identified through being the only overhead valve ("OHV") V8 engine produced by BMW, since all other BMW V8 engines use a Overhead camshaft#Dual overhead camshaft, dual overhead camshaft valvetrain. Although not a direct replacement, in 1965 the six-cylinder BMW M30 engine took the OHV V8's place at the top of BMW's engine range. Development The BMW 501, which began production in 1952, was the first car produced by BMW after World War II. It was powered by the BMW M337 straight-six engine (based on the pre-war BMW M78 engine), which struggled with the mass of the 501. The competing Mercedes-Benz W187 was powered by a larger engine, which provided superior performance. However, BMW had been developing a V8 engine sin ...

BMW Engines
BMW has been producing engines for automobiles, motorcycles and aircraft since 1917, when the company began production of an inline-six aircraft engine. They have been producing automobile engines since 1933. Motorcycle engines Automotive petrol engines BMW is well known for its history of inline-six (straight-six) engines, a layout it continues to use to this day despite most other manufacturers switching to a V6 layout. The more common inline-four and V8 layouts are also produced by BMW, and at times the company has produced inline-three, V10 and V12 engines, BMW also engineered non-production customised engines especially for motorsports which include the M12/13 1.5-Liter straight 4 piston turbocharged engine from 1982 to 1987 for Brabham, Arrows and Benetton Formula One teams, the E41/P83 3.0-Liter V10 from 2000 to 2005 for Williams F1 Team and the P86/8 2.4-Liter V8 for their own F1 team partnering with Sauber F1 from 2006 to 2009, with which the company ...

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 Badener Metall-Waren-Fabrik, but practically created only by Lancia in the same year, for its car engines. It was further developed by Reynolds, now Rheinmetall Automotive. In the United States, Chevrolet was the first to use Reynolds A390 in the Chevrolet Vega. The Alusil aluminium alloy is commonly used to make linerless aluminium alloy engine blocks. There is no coating applied to the cylinder bore and blocks are not honed conventionally. During the manufacturing process, a chemical or mechanical process is used to remove aluminum from the surface of the cylinder bore, exposing a very hard silicon precipitate. These exposed silicon particles, which under a microscope look like small islands, allow for oil to collect in the area surrounding them, thus form ...

Sulfur
Sulfur ( American spelling and the preferred IUPAC name) or sulphur ( Commonwealth spelling) is a chemical element; it has symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with the chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature. Sulfur is the tenth most abundant element by mass in the universe and the fifth most common on Earth. Though sometimes found in pure, native form, sulfur on Earth usually occurs as sulfide and sulfate minerals. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in ancient India, ancient Greece, China, and ancient Egypt. Historically and in literature sulfur is also called brimstone, which means "burning stone". Almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum.. Downloahere Th ...

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 was initially developed to allow Wankel engine apex seals to work directly against the aluminum block. This coating allowed aluminum 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 aluminum cylinders also gave a much better heat conductivity and lower friction 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, and Kohler Engines, and as a repair replacement for factory-chromed snowmobiles, dirt bik ...

De Tomaso Guarà
The De Tomaso Guarà is a sports car and the last project the founder and owner Alejandro de Tomaso put into the market. Presented at the 1993 Geneva Motor Show, the Guarà was initially available in coupé body-style. Later a roadster and an open-top barchetta bodystyle became available. The latter corresponds to the coupé but without roof and proper windscreen; a small air deflector protects the passenger and the driver from the passing wind and the car had to be driven while wearing a helmet. Development The Guarà is based on the Maserati Barchetta Stradale prototype from 1991 which was meant to be the street-legal variant of the track-only car. A take-over of Maserati by Fiat prevented Alejandro de Tomaso from realising such a variant of the Barchetta manufactured by Maserati as Maserati ceased production of the Barchetta under its new owner. The car was thus manufactured by De Tomaso and was named Guarà. The Guarà was designed by Carlo Gaino of "Synthesis Design" who also ...

BMW 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 the 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 ($1.13 billion USD or €990 million in 2025). BMW used CAD tools, still unusual at the time, to design the car's all-new body.

Forging
Forging is a manufacturing process involving the shaping of metal using localized compression (physics), compressive forces. The blows are delivered with a hammer (often a power hammer) or a die (manufacturing), die. Forging is often classified according to the temperature at which it is performed: cold forging (a type of cold working), warm forging, or hot forging (a type of hot working). For the latter two, the metal is heated, usually in a forge. Forged parts can range in weight from less than a kilogram to hundreds of metric tons.Degarmo, p. 389 Forging has been done by metalsmith, smiths for millennia; the traditional products were kitchenware, household hardware, hardware, hand tools, edged weapons, cymbals, and jewellery. Since the Industrial Revolution, forged parts are widely used in mechanism (engineering), mechanisms and machines wherever a component requires high strength of materials, strength; such forgings usually require further processing (such as machining) ...
