MV Agusta 500 Six
The MV Agusta 500 6 cilindri (''MV Agusta 500 6-cylinder'') was a prototype racing motorcycle built by the Varese company MV Agusta in 1957. Only one prototype was made. Background MV Agusta had won the championship in the 500, 250 and 125 cc classes of the 1956 season. However, the 1957 season promised stiff competition, especially in the premier 500 class, where the Moto Guzzi V8 and the Gilera 500 4C had shown great potential. Undecided whether to go down the road of evolutionary refinement, as Gilera had, or innovation, like the Moto Guzzi, Count Agusta opted for a dual strategy that included the development of the victorious " 500 4C" and, simultaneously, the commissioning of a new multi-cylinder engine. Development and Technology The outline of the project was conceived in the first months of 1956. Sporting director Nello Pagani was in charge of the project, which was carried out with the maximum secrecy. The engine had cylinders and cylinder head made of light alloy wa ...

MV Agusta
MV Agusta (, full name: MV AGUSTA Motor S.p.A., original name: Meccanica Verghera Agusta or MV) is a motorcycle manufacturer founded by Count Domenico Agusta on 19 January 1945 as one of the branches of the Agusta aircraft company near Milan in Cascina Costa, Italy. The abbreviation MV stands for ''Meccanica'' (mechanics) ''Verghera'', the hamlet where the first MVs were made. The modern headquarters and main production facilities are located in Varese, Italy on the shore of Lake Varese. History 1943–1945: From idea to mass production It all began in the early years of the 20th century, when Count Giovanni Agusta left Sicily for northern Italy, where he built his first aircraft, the AG.1, four years after the Wright brothers had made history in the US. The First World War, which demonstrated the prospects of aviation, prompted the count to act decisively – and in 1923, in the town of Samarate, he founded the Costruzioni Aeronautiche Giovanni Agusta S.A.

MV Agusta 500 Racers
The MV Agusta 500cc road racers were motorcycles that the manufacturer MV Agusta built and which were used to compete in 500cc Grand Prix motorcycle racing series between 1950 and 1976. 18 500cc world championship titles were achieved with these machines ridden by John Surtees, Gary Hocking, Mike Hailwood, Giacomo Agostini and Phil Read between 1958 and 1974. History Piero Remor had developed racing engines for the Gilera brand before World War II. In addition to a supercharged 500cc four cylinder engine, he also built a 250cc four cylinder. After the war, he based a new 500cc machine on the pre-war designs. The new racer was tested for the first time in 1948. This Gilera 500 4C did not perform well, but Remor refused to make changes and put the blame on the riders. In 1949 he was fired by Giuseppe Gilera. Piero Taruffi became responsible for the development of the Gilera, which became the most successful racing engine in the 1950s. Piero Remor was hired by Count Domenico Agus ...

Autodromo Di Modena
Autodromo di Modena (or Aerautodromo di Modena) was a race track on the edge of Modena in Italy. The track had a length of . It was opened in 1950 and the circuit was crossed by an airstrip of about in length which was used by the local flying club. The track hosted nine editions of the Modena Grand Prix for Formula One and Formula Two racing cars, the last one in 1961. The circuit continued to host other racing events (sportcars, grand touring, Formula Junior, motorcycles) until 1975. In the 1960s and 1970s the track also served as a test track for Ferrari and Maserati during the morning or afternoon (but not both) on week days. At other times of day it was used by residents of the adjacent military camp for driver training while maintaining its original function of airport for private flights. Ferrari driver Mike Parkes, an accomplished pilot, used to fly in regularly from England on his own craft. Despite the expansion of nearby Modena, which involved a proliferation of a ...

Italian Motorcycle Grand Prix
The Italian motorcycle Grand Prix is a motorcycling event that is part of the Grand Prix motorcycle racing season. From 1949 to 1990 the event was known by the it, Gran Premio Delle Nazioni (''Nations Grand Prix''). It was one of the original rounds of the Grand Prix motorcycle racing calendar. The race was held exclusively at Monza for the first 23 years of its existence. From 1972 to 1993, the event rotated among several circuits and has been held at the Mugello Circuit since 1994, except 2020 in which the race was cancelled due to the outbreak of COVID-19..

Autodromo Nazionale Monza
The Monza Circuit ( it, Autodromo Nazionale di Monza, , National Automobile Racetrack of Monza) is a race track near the city of Monza, north of Milan, in Italy. Built in 1922, it was the world's third purpose-built motor racing circuit after Brooklands and Indianapolis Motor Speedway, Indianapolis and the oldest in mainland Europe. The circuit's biggest event is the Italian Grand Prix. With the exception of the 1980 Italian Grand Prix, 1980 running, the race has been hosted there since 1949 Italian Grand Prix, 1949. Built in the Royal Villa of Monza park in a woodland setting, the site has three tracks – the Grand Prix motor racing, Grand Prix track, the Junior track, and a high speed oval track with steep bankings which was left unused for decades and had been decaying until it was restored in the 2010s. The major features of the main Grand Prix track include the ''Curva Grande'', the ''Curva di Lesmo'', the ''Variante Ascari'' and the ''Curva Alboreto'' (formerly ''Curv ...

Carburetor
A carburetor (also spelled carburettor) is a device used by an internal combustion engine to control and mix air and fuel entering the engine. The primary method of adding fuel to the intake air is through the venturi tube in the main metering circuit, however various other components are also used to provide extra fuel or air in specific circumstances. Since the 1990s, carburetors have been largely replaced by fuel injection for cars and trucks, however carburetors are still used by some small engines (e.g. lawnmowers, generators and concrete mixers) and motorcycles. Diesel engines have always used fuel injection instead of carburetors. Etymology The name "carburetor" is derived from the verb ''carburet'', which means "to combine with carbon," or in particular, "to enrich a gas by combining it with carbon or hydrocarbons." Thus a carburetor mixes intake air with hydrocarbon-based fuel, such as petrol or autogas (LPG). The name is spelled "carburetor" in American English ...

Dell'Orto
Dell'Orto is an Italian company, headquartered in Cabiate, specialized in the construction of carburetors and electronic injection systems. The company was founded in 1933 as "Società anonima Gaetano Dell'Orto e figli" (Gaetano Dell’Orto and Sons) but actually only founded by Gaetano's sons, Luigi Piero and Giuseppe. The first production was carburetors for motorbikes. Right before World War II the company started producing carburetors with aluminum body, for competitive racing. Under the second Dell'Orto generation, towards the end of the 60s, the company began producing OEM carburetors for the Fiat group, as well as other Italian and foreign manufacturers (i.e. Flandria, Belgium). At the end of the 1980s, under the supervision of Luigi Dell'Orto (son of Gaetano), the company's first injection systems were released. In 2006, the company expanded on the Indian market, opening Dell'Orto India. In September 2009, Dell’Orto India Private Limited, founded in 2006 with the coope ...

Poppet Valve
A poppet valve (also called mushroom valve) is a valve typically used to control the timing and quantity of gas or vapor flow into an engine. 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. The poppet valve was invented in 1833 by American E.A.G. Young of the New Castle and Frenchtown Turnpike and Railroad Company, Newcastle and Frenchtown Railroad. Young had patented his idea, but the 1836 U.S. Patent Offic ...

Overhead Camshaft
An overhead camshaft (OHC) engine is a piston engine where the camshaft is located in the cylinder head above the combustion chamber. This contrasts with earlier overhead valve engines (OHV), where the camshaft is located below the combustion chamber in the engine block. ''Single overhead camshaft'' (SOHC) engines have one camshaft per bank of cylinders. ''Dual overhead camshaft'' (DOHC, also known as "twin-cam".) engines have two camshafts per bank. The first production car to use a DOHC engine was built in 1910. Use of DOHC engines slowly increased from the 1940s, leading to many automobiles by the early 2000s using DOHC engines. Design In an OHC engine, the camshaft is located at the top of the engine, above the combustion chamber. This contrasts the earlier overhead valve engine (OHV) and flathead engine configurations, where the camshaft is located down in the engine block. The valves in both OHC and OHV engines are located above the combustion chamber; however an OHV ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alloy
An alloy is a mixture of chemical elements of which at least one is a metal. Unlike chemical compounds with metallic bases, an alloy will retain all the properties of a metal in the resulting material, such as electrical conductivity, ductility, opacity (optics), opacity, and lustre (mineralogy), luster, but may have properties that differ from those of the pure metals, such as increased strength or hardness. In some cases, an alloy may reduce the overall cost of the material while preserving important properties. In other cases, the mixture imparts synergistic properties to the constituent metal elements such as corrosion resistance or mechanical strength. Alloys are defined by a metallic bonding character. The alloy constituents are usually measured by mass percentage for practical applications, and in Atomic ratio, atomic fraction for basic science studies. Alloys are usually classified as substitutional or interstitial alloys, depending on the atomic arrangement that forms the ...

Cylinder Head
In an internal combustion engine, the cylinder head (often abbreviated to simply "head") sits above the cylinders and forms the roof of the combustion chamber. In sidevalve engines, the head is a simple sheet of metal; whereas in more modern overhead valve and overhead camshaft engines, the cylinder head is a more complicated block often containing inlet and exhaust passages, coolant passages, valves, camshafts, spark plugs and fuel injectors. Most straight engines have a single cylinder head shared by all of the cylinders and most V engines have two cylinder heads (one per bank of cylinders). Design A summary of engine designs is shown below, in chronological order for automobile usage. Sidevalve engines In a flathead (''sidevalve'') engine, all of the valvetrain components are contained within the block, therefore the head is usually a simple sheet of metal bolted to the top of the engine block. Sidevalve engines were once universal in automobiles but are now lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
