Ducati 996
The Ducati 996 is a Ducati sport bike motorcycle made from 1999 to 2002, based upon the earlier 916. Model history From 1999, there were three different models of the 996: a base, or Biposto; the 996S with Öhlins suspension; the 996SPS (Europe only) which had a more powerful engine and less weight thanks to some titanium and carbon fibre parts. From 2001 the 996R replaced the 996SPS and featured the new Testastretta engine. There was also the 748, which offered less horsepower. The 996 had larger pistons, larger valves, a stronger crankshaft and crankcases ported from the 916 SPS. But since the 916 camshaft gave a softer, less peaky power delivery and less top-end power ( versus the SPS’s ) the 996 was built with a new air intake system with two fuel injectors per cylinder. A new airbox and a distinctive underseat exhaust system were also built into the new design. The chassis was also modified. Lighter wheels were introduced along with improved cal ...

Crankshaft
A crankshaft is a mechanical component used in a piston engine to convert the reciprocating motion into rotational motion. The crankshaft is a rotating shaft containing one or more crankpins, that are driven by the pistons via the connecting rods. The crankpins are also called ''rod bearing journals'', and they rotate within the "big end" of the connecting rods. Most modern crankshafts are located in the engine block. They are made from steel or cast iron, using either a forging, casting or machining process. Design The crankshaft located within the engine block, held in place via main bearings which allow the crankshaft to rotate within the block. The up-down motion of each piston is transferred to the crankshaft via connecting rods. A flywheel is often attached to one end of the crankshaft, in order to smoothen the power delivery and reduce vibration. A crankshaft is subjected to enormous stresses, in some cases more than per cylinder. Crankshafts for single-cylin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ducati Motorcycles
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. ...

Subframe
A subframe is a structural component of a vehicle, such as an automobile or an aircraft, that uses a discrete, separate structure within a larger body-on-frame or unit body to carry certain components, such as the engine, drivetrain, or suspension. The subframe is bolted and/or welded to the vehicle. When bolted, it is sometimes equipped with rubber bushings or springs to dampen vibration. The principal purposes of using a subframe are, to spread high chassis loads over a wide area of relatively thin sheet metal of a monocoque body shell, and to isolate vibrations and harshness from the rest of the body. For example, in an automobile with its powertrain contained in a subframe, forces generated by the engine and transmission can be damped enough that they will not disturb passengers. As a natural development from a car with a full chassis, separate front and rear subframes are used in modern vehicles to reduce the overall weight and cost. In addition a subframe yields benefi ...

The Matrix Reloaded
''The Matrix Reloaded'' is a 2003 American science-fiction action film written and directed by the Wachowskis. It is a sequel to ''The Matrix'' (1999) and the second installment in the ''Matrix'' film series. The film stars Keanu Reeves, Laurence Fishburne, Carrie-Anne Moss, Hugo Weaving and Gloria Foster who reprise their roles from the previous film, while Jada Pinkett Smith was introduced in the cast. The film premiered on May 7, 2003, in Westwood, Los Angeles, California, and had its worldwide release by Warner Bros. Pictures on May 15, 2003, including a screening out of competition at the 2003 Cannes Film Festival.

Shock Absorber
A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction). Description Pneumatic and hydraulic shock absorbers are used in conjunction with cushions and springs. An automobile shock absorber contains spring-loaded check valves and orifices to control the flow of oil through an internal piston (see below). One design consideration, when designing or choosing a shock absorber, is where that energy will go. In most shock absorbers, energy is converted to heat inside the viscous fluid. In hydraulic cylinders, the hydraulic fluid heats up, while in air cylinders, the hot air is usually exhausted to the atmosphere. In other types of shock absorbers, such as electromagnetic types, the dissipated energy can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stiction
Stiction is the static friction that needs to be overcome to enable relative motion of stationary objects in contact. The term is a portmanteau of the words ''static'' and ''friction'', and is perhaps also influenced by the verb '' to stick''. Any solid objects pressing against each other (but not sliding) will require some threshold of force parallel to the surface of contact in order to overcome static adhesion. Stiction is a ''threshold'', not a continuous force. However, stiction might also be an illusion made by the rotation of kinetic friction. In situations where two surfaces with areas below the micrometer scale come into close proximity (as in an accelerometer), they may adhere together. At this scale, electrostatic and/or Van der Waals and hydrogen bonding forces become significant. The phenomenon of two such surfaces being adhered together in this manner is also called stiction. Stiction may be related to hydrogen bonding or residual contamination. Automobiles Sticti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Airbox
An airbox is an empty chamber on the inlet of most combustion engines. It collects air from outside and feeds it to the intake hoses of each cylinder. Older engines drew air directly from the surroundings into each individual carburetor. Modern engines instead draw air into an airbox, which is connected by individual hoses to each carburetor or directly to the intake ports in fuel-injected engines, thus avoiding an extra intake manifold. The airbox allows the use of one air filter instead of multiples, reducing complexity. Developments arising from concerns about engine emissions during the late 1970s allow the airbox to collect pump gases from the crankcase and the tank air vent and re-feed them to the engine. Developments Since the 1990s, engine designers also sought to exploit the properties of oscillating gas to improve performance. Many high-performance motorcycles have the airbox fed from funnels in the front of the bike, where increased pressure forces more air into t ...

Fuel Injector
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 a ...
