BMW K100
The BMW K100 is a family of four-cylinder 987 cc motorcycles that were manufactured by BMW Motorrad, BMW from 1983 to 1992. Background As the 1970s came to an end, BMW faced three problems from developing its flat-twin boxer engine further: *Emissions regulations being developed in the United States and the European Union meant that more control was needed over the amount of fuel entering the combustion chamber. From an engineering standpoint, this was easier to achieve with more cylinders at an overall smaller displacement. *The market-led development of bikes was leading to the Japanese factories developing smoother and quicker machines based around a four-cylinder format. *Bike comparison in the media at the time was based around top speed, and a four-cylinder when fully developed created more power. In combination, this meant that BMW's marketing to users of a superior bike, allowing them to price at a premium, was being quickly lost, resulting in a loss of sales and mar ...

Straight-three Engine
A straight-three engine (also called an inline-triple or inline-three) is a three-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. Less common than straight-four engine, straight-three engines have nonetheless been used in various motorcycles, cars and agricultural machinery. Design A crankshaft angle of 120 degrees is typically used by straight-three engines, since this results in an evenly spaced firing interval. Another benefit of this configuration is perfect primary balance and secondary balance, however an end-to-end rocking couple is induced because there is no symmetry in the piston velocities about the middle piston. A balance shaft is sometimes used to reduce the vibrations caused by the rocking couple. Other crankshaft angles have been used occasionally. The 1976–1981 Laverda Jota motorcycle used a 180 degree crankshaft, where the outer pistons rise and fall together and inner cylinder is offset from them by 180 degrees ...

1991 BMW K100RS ABS
It was the final year of the Cold War, which had begun in 1947. During the year, the Soviet Union Dissolution of the Soviet Union, collapsed, leaving Post-soviet states, fifteen sovereign republics and the Commonwealth of Independent States, CIS in its place. In July 1991, India abandoned its policies of dirigism, license raj and autarky and began extensive Economic liberalisation in India, liberalisation to its economy. This increased Economy of India, GDP but also increased income inequality in India, income inequality over the next two decades. A United Nations, UN-authorized coalition of the Gulf War, coalition force from 34 nations fought against Ba'athist Iraq, Iraq, which had Invasion of Kuwait, invaded and Kuwait Governorate, annexed Kuwait in the previous year, 1990. The conflict would be called the Gulf War and would mark the beginning of a since-constant American military presence in the Middle East. The clash between Republic of Serbia (1990–2006), Serbia and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Longitudinal Engine
In automotive engineering, a longitudinal engine is an internal combustion engine in which the crankshaft is oriented along the long axis of the vehicle, from front to back. See also: transverse engine Use This type of motor is usually used for rear-wheel drive cars, except for some Audi, SAAB, the Oldsmobile Toronado, and the 1967 Cadillac Eldorado equipped with longitudinal engines in front wheel drive. In front-wheel drive cars a transverse engine is usually used. Trucks often have longitudinal engines with rear-wheel drive. For motorcycles, the use of a particular type depends on the drive: in the case of a chain or belt drive a transverse engine is usually used, and with shaft drives a longitudinal engine. Longitudinal engines in motorcycles do have one disadvantage: the "tipping point" of the crankshaft tilts along the entire motorcycle to a greater or lesser degree when accelerating. This is partly resolved by having other components, such as the generator and the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swingarm
A swingarm ( or swinging arm), originally known as a swing fork or pivoted fork, is a single or double sided mechanical device which attaches the rear wheel of a motorcycle to its body, allowing it to pivot vertically. The main component of the rear suspension of most modern motorbikes and ATVs, it holds the rear axle firmly, while pivoting to absorb bumps and suspension loads induced by the rider, acceleration, and braking. Originally motorcycles had no rear suspension, as their frames were little more than stronger versions of the classic diamond frame of a bicycle. Many types of suspension were tried, including Indian's leaf spring suspended swingarm, and Matchless's cantilevered coiled-spring swingarm. Immediately before and after World War II, the plunger suspension, in which the axle moved up and down two vertical posts, became commonplace. In the latter, the movement in each direction was against coiled springs. Some manufacturers, such as Greeves, used swinga ...

United States Environmental Protection Agency
The Environmental Protection Agency (EPA) is an independent agency of the United States government tasked with environmental protection matters. President Richard Nixon proposed the establishment of EPA on July 9, 1970; it began operation on December 2, 1970, after Nixon signed an executive order. The order establishing the EPA was ratified by committee hearings in the House and Senate. The agency is led by its administrator, who is appointed by the president and approved by the Senate. The current administrator is Lee Zeldin. The EPA is not a Cabinet department, but the administrator is normally given cabinet rank. The EPA has its headquarters in Washington, D.C. There are regional offices for each of the agency's ten regions, as well as 27 laboratories around the country. The agency conducts environmental assessment, research, and education. It has the responsibility of maintaining and enforcing national standards under a variety of environmental laws, in consultat ...

Types Of Motorcycles
In the market, there is a wide variety of types of motorcycles, each with unique characteristics and features. Models vary according to the specific needs of each user, such as ''standard'', ''cruiser'', ''touring'', ''sports'', ''off-road'', ''dual-purpose'', ''scooters'', etc.Scooters are a type of motorcycle: * * * * * * Often, some hybrid types like ''sport touring'' are considered as an additional category. There is no universal system for classifying all types of motorcycles. However, some authors argue that there are generally six categories recognized by most motorcycle manufacturers and organizations, making clear distinctions between these six main types and other motorcycles. For example, scooters, mopeds, underbones, minibikes, pocket bikes, electric bikes such as surrons or talarias or even skark vargs, and three-wheeled motorcycles are often excluded from the main categories within these classifications, but other classification schemes may also include these ...

Jetronic
Jetronic is a trade name of a manifold injection technology for automotive petrol engines, developed and marketed by Robert Bosch GmbH from the 1960s onwards. Bosch licensed the concept to many automobile manufacturers. There are numerous variations of the technology offering technological development and refinement, all but the Mono-Jetronic produced 1988-1995) being multi-point injection systems. D-Jetronic (1967–1979) Analogue multi-point fuel injection, 'D' is from meaning pressure. Inlet manifold vacuum is measured using a pressure sensor located in, or connected to the intake manifold, in order to calculate the duration of fuel injection pulses. Originally, this system was called Jetronic, but the name D-Jetronic was later created as a retronym to distinguish it from subsequent Jetronic iterations. D-Jetronic was essentially a further refinement of the Electrojector fuel delivery system developed by the Bendix Corporation in the late 1950s. Rather than choosing to er ...

Formula Two
Formula Two (F2) is a type of Open-wheel car, open-wheel formula racing category first codified in 1948. It was replaced in 1985 by Formula 3000, but revived by the FIA from 2009 FIA Formula Two Championship season, 2009 to 2012 FIA Formula Two Championship season, 2012 in the form of the FIA Formula Two Championship (2009–2012), FIA Formula Two Championship. The name returned again in 2017 when the former GP2 Series became known as the FIA Formula 2 Championship. History While Formula One has generally been regarded as the pinnacle of open-wheeled auto racing, the high-performance nature of the cars and the expense involved in the series has always meant a need for a path to reach this peak. For much of the history of Formula One, Formula Two has represented the penultimate step on the motorsport ladder. Pre-war Prior to the Second World War, there usually existed a division of racing for cars smaller and less powerful than Grand Prix racers. This category was usually cal ...
