Alfa Romeo V6 Engine
The Alfa Romeo V6 engine (also called the Busso V6) is a 60° V6 engine made by Alfa Romeo from 1979 to 2005. It was developed in the early 1970s by Giuseppe Busso, and first used on the Alfa 6 with a displacement of and a SOHC 12-valve cylinder head. Later versions ranged from and had DOHC 24-valve valvetrains. The original design had short pushrods for the exhaust valves in a design similar to earlier Lancia Fulvia engines. The first DOHC version was in the 1993 Alfa Romeo 164, with an aluminium alloy engine block and head with sodium filled exhaust valves. The Alfa Romeo V6 has been used in kit cars like the Ultima GTR, Hawk HF Series, and DAX, as well as the Gillet Vertigo sports car and the Lancia Aurelia B20GT Outlaw. In August 2011 EVO magazine wrote that "the original Alfa Romeo V6 was the most glorious-sounding six-cylinder road engine ever," and has been called the "Violin of Arese" or "Alfa's Violin". The Alfa Romeo V6 engine has also been used in ice resurfa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giuseppe Busso
Giuseppe Busso (Turin, April 27, 1913 – Arese, January 3, 2006) was an Italian mechanical and engine designer mostly known for his tenure at Alfa Romeo and Ferrari. Biography Busso was born in Turin. After graduating in Industrial Design at the Polytechnic University of Turin, in 1937 he began working for Fiat's aviation engine department. In January 1939 he moved to Alfa Romeo where he worked under the guidance of Orazio Satta Puliga. His main responsibility was racing car engines. In 1946 he became technical director for Ferrari and thus took part in the development of the Ferrari Colombo V12 engine. Busso returned to Alfa Romeo in 1948 and worked there until 1977. He was in charge of mechanical engineering for Alfa Romeo road cars, taking part in the creation of the Alfa Romeo 1900, Giulietta, Giulia, 1750, 2000 and Alfetta. With the Giulietta, Busso introduced the four cylinder Alfa Romeo Twin Cam engine, also known as the Nord engine. Another creation of his was the ...

Petrol
Gasoline (North American English) or petrol ( Commonwealth English) is a petrochemical product characterized as a transparent, yellowish, and flammable liquid normally used as a fuel for spark-ignited internal combustion engines. When formulated as a fuel for engines, gasoline is chemically composed of organic compounds derived from the fractional distillation of petroleum and later chemically enhanced with gasoline additives. It is a high-volume profitable product produced in crude oil refineries. The ability of a particular gasoline blend to resist premature ignition (which causes knocking and reduces efficiency in reciprocating engines) is measured by its octane rating. Tetraethyl lead was once widely used to increase the octane rating but is not used in modern automotive gasoline due to the health hazard. Aviation, off-road motor vehicles, and racing car engines still use leaded gasolines. Other substances are frequently added to gasoline to improve chemical stabilit ...

Engine Block
In an internal combustion engine, the engine block is the structure that contains the cylinders and other components. The engine block in an early automotive engine consisted of just the cylinder block, to which a separate crankcase was attached. Modern engine blocks typically have the crankcase integrated with the cylinder block as a single component. Engine blocks often also include elements such as coolant passages and oil galleries. The term "cylinder block" is often used interchangeably with "engine block". However, technically, the block of a modern engine (i.e., multiple cylinders integrated with another component) would be classified as a monobloc. __TOC__ Construction The main structure of an engine typically consists of the cylinders, coolant passages, oil galleries, crankcase, and cylinder head(s). The first production engines of the 1880s to 1920s usually used separate components for each element, which were bolted together during engine assembly. Modern en ...

Aluminium Alloy
An aluminium alloy ( UK/IUPAC) or aluminum alloy ( NA; see spelling differences) is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, tin, nickel and zinc. There are two principal classifications, namely casting alloys and wrought alloys, both of which are further subdivided into the categories heat-treatable and non-heat-treatable. About 85% of aluminium is used for wrought products, for example rolled plate, foils and extrusions. Cast aluminium alloys yield cost-effective products due to their low melting points, although they generally have lower tensile strengths than wrought alloys. The most important cast aluminium alloy system is Al–Si, where the high levels of silicon (4–13%) contribute to give good casting characteristics. Aluminium alloys are widely used in engineering structures and components where light weight or corrosion resistance is required.I. J. Polmear, ''Light Alloys'', A ...

Alfa Romeo 164
The Alfa Romeo 164 (Type 164) is a four-door executive saloon manufactured and marketed by Italian automaker Alfa Romeo from 1987 to 1998, styled by Pininfarina, and cooperatively designed and sharing platforms and numerous elements with the Fiat Croma, Saab 9000 and Lancia Thema. The 164 succeeded the Alfa Romeo 90 and Alfa 6. The 164 was followed by the 166 in 1998, after a combined production total of 273,857 units. The 164 was also the last Alfa Romeo officially sold in the United States until the 2015 launch of the Alfa Romeo Giulia. Alfa Romeo withdrew after the 1995 model year due to reliability concerns and slow sales. Development The 164 started life as ''Project 156'' (not to be confused with Alfa Romeo 156) in 1980 as a proposal by Alfa Romeo engineer Filippo Surace as a modular platform for a range of cars aimed to replace the Alfa Sud and Alfetta. Project 156 was meant to be a rear-wheel drive and powered by the Alfa Romeo's ''Busso'' V6. A saloon body was de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lancia V4 Engine
Italian automobile company Lancia was the first to manufacture cars with V4 engine, V4 and V6 engine, V6 engines in series-production. This started with a number of V4-engine families, that were produced from the 1920s through 1970s. The Lancia V4 pioneered the narrow-angle V engine design, more recently seen in Volkswagen's VR5 engine, VR5 and VR6 engine, VR6 engines. By using very shallow V-angles — between 10° and 20° — both rows of cylinders could be housed in an engine block with a single cylinder head, like a straight engine. A determining characteristic was the use of overhead camshafts (either single or double), in which a camshaft would serve the same function for all cylinders — in ''both'' cylinder banks. Lambda The first V4 was used in the Lancia Lambda, Lambda from 1922 through 1931. It was a 20° narrow-angle aluminium design. All three engine displacements shared the same long stroke, and all were SOHC designs with a single camshaft serving both banks of c ...

Exhaust Valve
A poppet valve (also sometimes called mushroom valve) is a valve typically used to control the timing and quantity of petrol (gas) or vapour flow into or out of an engine, but with many other applications. It consists of a hole or open-ended chamber, usually round or oval in cross-section, and a plug, usually a disk shape on the end of a shaft known as a valve stem. The working end of this plug, the valve face, is typically ground at a 45° bevel to seal against a corresponding valve seat ground into the rim of the chamber being sealed. The shaft travels through a valve guide to maintain its alignment. A pressure differential on either side of the valve can assist or impair its performance. In exhaust applications higher pressure against the valve helps to seal it, and in intake applications lower pressure helps open it. Etymology The word poppet shares etymology with "puppet": it is from the Middle English ''popet'' ("youth" or "doll"), from Middle French ''poupette'', which i ...

Pushrod
A valvetrain is a mechanical system that controls the operation of the intake and exhaust valves in an internal combustion engine. The intake valves control the flow of air/fuel mixture (or air alone for direct-injected engines) into the combustion chamber, while the exhaust valves control the flow of spent exhaust gases out of the combustion chamber once combustion is completed. Layout The valvetrain layout is largely dependent on the location of the camshaft. The common valvetrain configurations for piston engines, in order from oldest to newest, are: * Flathead engine: A single camshaft and the valves are located in the engine block below the cylinder or cylinder bank. * Overhead valve engine: A single camshaft remains in the block below the cylinder(s), however the valves are located in the cylinder head above the combustion chamber. * Overhead camshaft engine: Both the valves and one or more camshafts are located in the cylinder head above the cylinders or cylinder banks. ...

Cylinder Head
In a piston engine, the cylinder head sits above the cylinders, forming the roof of the combustion chamber. In sidevalve engines the head is a simple plate of metal containing the spark plugs and possibly heat dissipation fins. In more modern overhead valve and overhead camshaft engines, the head is a more complicated metal block that also contains the inlet and exhaust passages, and often coolant passages, valvetrain components, and fuel injectors. Number of cylinder heads A piston engine typically has one cylinder head per bank of cylinders. Most modern engines with a "straight" (inline) layout today use a single cylinder head that serves all the cylinders. Engines with a "V" layout or "flat" layout typically use two cylinder heads (one for each cylinder bank), however a small number of 'narrow-angle' V engines (such as the Volkswagen VR5 and VR6 engines) use a single cylinder head spanning the two banks. Most radial engines have one head for each cylind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engine Displacement
Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. It is commonly used as an expression of an engine's size, and by extension as an indicator of the power (through mean effective pressure and rotational speed) an engine might be capable of producing and the amount of fuel it should be expected to consume. For this reason displacement is one of the measures often used in advertising, as well as regulating, motor vehicles. It is usually expressed using the metric units of cubic centimetres (cc or cm3, equivalent to millilitres) or litres (l or L), orparticularly in the United States cubic inches (CID, cu in, or in3). Definition The overall displacement for a typical reciprocating piston engine is calculated by multiplying together three values; the distance travelled by the piston (the stroke length), the circular area of the cylinder, and the number of cylinders in the whole e ...

Alfa Romeo Alfa 6
The Alfa Romeo Alfa 6 (Type 119) is an executive car produced by the Italian automaker Alfa Romeo from 1979 to 1986. Its name refers to the six cylinders of the Alfa Romeo V6 engine, which made its first appearance on this car. History On its launch in 1979, the Alfa 6 was the flagship of the Alfa Romeo range. The four-door body was fairly conventional and used a similar style to the existing Alfa Romeo Alfetta, and in fact both vehicles share a great number of parts, including door panels; Design work on the 6 was done prior to the Alfetta, but the fuel crisis of 1973 delayed further development and led to the 6's belated 1979 debut. The styling was not particularly aerodynamic but the drag coefficient was an acceptable 0.41. Power came from an all-new 2.5-litre V6 engine which generated at 5,600 rpm using a total of six carburettors and a single, belt driven camshaft in each cylinder head. Power steering, power windows, central locking, electric wing mirrors and a 25% lim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
