Ducati L-twin Engine
The L-twin is a naturally aspirated two-cylinder petrol engine by Ducati. It uses a 90-degree layout and 180-degree firing order as is mounted with one cylinder horizontal. The next new Ducati engine to appear after the Ducati Apollo was the 90° V-twin, initial Grand Prix racing versions being 500 cc, and the production bikes were 750 cc. There was also the Ducati 750 Imola Desmo that won at Imola in 1972. These engines had bevel gear shaft drive to the overhead camshaft, and were produced in round, square, and Mille crankcases. In the 1980s, these gave way to the belt drive camshaft engines that have continued to this day, in air-cooled and liquid-cooled form. The Mille used a plain bearing crank, like the belt models. Engines V-twin or L-twin A two-cylinder engine with its cylinders aligned in two banks radiating out from the crankshaft, forming a V angle, is called a V-twin. The Ducati V-twin has the V tilted forward, so the front cylinder is nearly parallel to the ground, ...

Ducati V-twin Motor
Ducati Motor Holding S.p.A. () is the motorcycle-manufacturing division of Italian company Ducati, headquartered in Bologna, Italy. The company is directly owned by Italian automotive manufacturer Lamborghini, whose German parent company is Audi, itself owned by the Volkswagen Group. History In 1926 Antonio Cavalieri Ducati and his three sons, Adriano, Marcello, and Bruno, founded ''Società Scientifica Radiobrevetti Ducati'' (SSR Ducati) in Bologna to produce vacuum tubes, condensers and other radio components. In 1935 they had become successful enough to enable construction of a new factory in the Borgo Panigale area of the city. Production was maintained during World War II, despite the Ducati factory being a repeated target of Allied bombing. It was finally destroyed by around 40 Consolidated B-24 Liberators on 12 October 1944 as part of the United States Army Air Forces's Operation Pancake, which involved some 700 aircraft flying from airfields in the Province of Foggia. ...

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 ...

Ducati Bipantah
Ducati Bipantah was a prototype 90° V4 four-stroke motorcycle engine made by Ducati in 1981. It was designed by Pierluigi Mengoli under the supervision of Fabio Taglioni. It had four cylinders and made coupling two Ducati Pantah V-twin engines. It remained a prototype, although it had good results during dyno-tests. The project ended in late 1982, when then-owners VM Motori decided not to build the bike for which the motor was intended for. History Ducati's technical director, Fabio Taglioni, desired to launch a whole new family of Ducati motorbikes to provide the manufacturer a solid position on markets, with reasonable production figures. At the beginning of the 1980s, world motorcycle sales were decreasing and the public was losing interest on Ducati V-twins models. So, Taglioni thought that a brand new project would be the best choice, but it had to be different from Japanese models: first he conceived a 90° V-4, a wooden-metal model of which was realized in 1980, then he o ...

Kawasaki Z1
The Kawasaki Z1 is a four-cylinder, air-cooled, double-overhead camshaft, carbureted, chain-drive motorcycle introduced in 1972 by Kawasaki. Following the introduction of Honda's CB750 in 1968, the Z1 helped popularize the in-line, across-the-frame four-cylinder, a format that became known as the ''Universal Japanese Motorcycle'' or ''UJM.'' The Z1 was noted for being the first large-capacity Japanese four-cylinder motorcycle to use the double-overhead-camshaft system on a production motorcycle. When it was introduced, only the MV Agusta 750 S used this system; it was a very expensive limited-production machine, as opposed to the Kawasaki which was less than half the price. Marketed variously as the Z1-900, 900 Z1 or 900 S4 ("Super Four"), the Z1 was the first of Kawasaki's Z models. History The Kawasaki Z1 was developed under the project name "New York Steak". In the late 1960s Kawasaki, already an established manufacturer of two-stroke motorcycles, had begun prototyping a ...

Mount Panorama Circuit
Mount Panorama Circuit is a motor racing track located in Bathurst, New South Wales, Australia. It is situated on Mount Panorama (Wahluu) and is best known as the home of the Bathurst 1000 motor race held each October, and the Bathurst 12 Hour event held each February. The track is a long street circuit, which is used as a public road when no racing events are being run, with many residences which can only be accessed from the circuit. The track has an unusual design by modern standards, with a vertical difference between its highest and lowest points, and grades as steep as 1:6.13. From the start-finish line, the track can be viewed in three sections; the short pit straight and then a tight left turn into the long, steep Mountain straight; the tight, narrow section across the top of the mountain itself; and then the long, downhill section of Conrod Straight, with the very fast Chase and the turn back onto the pit straight to complete the lap. Historically, the racetrack has ...

Ducati Pantah
The Ducati Pantah was an Italian motorcycle with a 90° V-twin engine, produced between 1980 and 1986. Unlike its predecessors which were bevel-gear OHC designs, the Pantah was the first Ducati to have belt-driven camshaft motors, thus forming the vanguard of the new generation of current Ducati V-twins. First shown December 1979, the Pantah came on the market as the 1980 500SL and the last of the line, the 650SL, was sold in 1986. Successful in racing as the 600 cc TT2 and later TT1 750 cc racer, the Pantah was a lighter, shorter wheelbase motorcycle, in a new trellis frame that was to become a trademark Ducati feature. Pantah 500 cc When Ducati's 1976 350 cc and 500 cc parallel twins proved to be a marketing failure, Fabio Taglioni went to work developing the a replacement. The Pantah 500 was developed from the last of the GP500 racers of 1973, the Pantah and its successors have shown that, contrary to the "received wisdom", a twin-cylinder biker can comp ...

Ducati 900GTS
The Ducati 860 GT was a Ducati motorcycle made in 1974 and 1975, replaced by the restyled 860 GTS for 1976–1979. In 1974–1975 the electric-start version was called the 860 GTE, while all models had electric start after 1975, and for the final two years, 1978–1979, the name was changed to 900 GTS. A USA market variant was made in all model years, in which the gearshift was "crudely moved" from the right to the left side of the engine by means an external rod. The 860 series used the engine and stressed member frame of Fabio Taglioni's original 750 GT 90° V-twin, with bevel cam drive and with the enlarged capacity achieved by using two of the Ducati 450 single-cylinder engine’s sleeves and pistons. The controversial angular design of the cosmetic elements was by noted car stylist Giorgetto Giugiaro. Giugiaro dispensed with both the sinuous tank shape and engine covers, and added large steel side covers to create an overall integrated effect. Giugiaro's squared-off, 'f ...

Fuel Injection
Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of an injector. This article focuses on fuel injection in reciprocating piston and Wankel rotary engines. All compression-ignition engines (e.g. diesel engines), and many spark-ignition engines (i.e. petrol engines, such as Otto or Wankel), use fuel injection of one kind or another. Mass-produced diesel engines for passenger cars (such as the Mercedes-Benz OM 138) became available in the late 1930s and early 1940s, being the first fuel-injected engines for passenger car use. In passenger car petrol engines, fuel injection was introduced in the early 1950s and gradually gained prevalence until it had largely replaced carburettors by the early 1990s. The primary difference between carburetion and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while a carburettor relies on suction created by intake ai ...
