Millet Motorcycle
The Millet motorcycle, designed in 1892 by Félix Théodore Millet, may have been the first motorcycle (or motorized bicycle) to use pneumatic tires. It had an unusual radial-configuration rotary engine incorporated into the rear wheel, believed to be the first one ever used to power a person-carrying vehicle of any type. Production history A prototype with rear-wheel rotary engine ran in 1892. Production rights were acquired by Alexandre Darracq in 1894. Production halted following an unsuccessful entry in the Paris–Bordeaux–Paris race of 1895. Technology The five cylinders were mounted radially in the rear wheel, with the connecting rods directly attached to the fixed crank of the hollow-drilled rear axle. The rear fender served as a fuel tank; a surface carburetor and air filter were located between the wheels.:de:Dinglers Polytechnisches Journal, Dinglers Polytechnisches Journal.

Alexandre Darracq
Alexandre Darracq (10 November 1855 – 1931) was a French investor, engineer, cycle manufacturer and automobile manufacturer. By 1904, Darracq was producing more than ten percent of all automobiles in France and he sold a substantial part of his business to British investors. He became fascinated by the possibilities of a rotary valve engine, put it into production and although it became a disaster for Darracq & Cie, persisted in installing it in Darracq products. He was obliged to retire in June 1912 aged 56. After the Armistice his name was dropped from his Suresnes factory's mass-produced products. In 1906 he founded Società Anonima Italiana Darracq (S.A.I.D.) in Milan, Italy, which became ocietàAnonima Lombarda Fabbrica Automobili (A.L.F.A.) in 1910 and eventually Alfa Romeo. Sewing machines and cycles Born Pierre Alexandre Darracq in Bordeaux, France, of Basque parents, he trained as a draftsman at the Arsenal in Tarbes, in the Hautes-Pyrénées département. He later ...

Rotary Engine
The rotary engine is an early type of internal combustion engine, usually designed with an odd number of cylinders per row in a radial configuration. The engine's crankshaft remained stationary in operation, while the entire crankcase and its attached cylinders rotated around it as a unit. Its main application was in aviation, although it also saw use in a few early motorcycles and automobiles. This type of engine was widely used as an alternative to conventional inline engines (straight or V) during World War I and the years immediately preceding that conflict. It has been described as "a very efficient solution to the problems of power output, weight, and reliability". By the early 1920s, the inherent limitations of this type of engine had rendered it obsolete. Description Distinction between "rotary" and "radial" engines A rotary engine is essentially a standard Otto cycle engine, with cylinders arranged radially around a central crankshaft just like a conventional ra ...

Motorcycle
A motorcycle (motorbike, bike, or trike (if three-wheeled)) is a two or three-wheeled motor vehicle steered by a handlebar. Motorcycle design varies greatly to suit a range of different purposes: long-distance travel, commuting, cruising, sport (including racing), and off-road riding. Motorcycling is riding a motorcycle and being involved in other related social activity such as joining a motorcycle club and attending motorcycle rallies. The 1885 Daimler Reitwagen made by Gottlieb Daimler and Wilhelm Maybach in Germany was the first internal combustion, petroleum-fueled motorcycle. In 1894, Hildebrand & Wolfmüller became the first series production motorcycle. Globally, motorcycles are comparably popular to cars as a method of transport. In 2021, approximately 58.6 million new motorcycles were sold around the world, fewer than the 66.7 million cars sold over the same period. In 2014, the three top motorcycle producers globally by volume were Honda (28%), Yamaha (17 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorized Bicycle
A motorized bicycle is a bicycle with an attached motor or engine and transmission used either to power the vehicle unassisted, or to assist with pedalling. Since it sometimes retains both pedals and a discrete connected drive for rider-powered propulsion, the motorized bicycle is in technical terms a true bicycle, albeit a power-assisted one. Typically they are incapable of speeds above . Powered by a variety of engine types and designs, the motorized bicycle formed the prototype for what would later become the motor driven cycle. Terminology The term motorized bicycle refers to just a bicycle combining pedal power and internal combustion engine power. However, the term could be used as an umbrella category to refer to bicycles using sources besides pedal power. Electric bicycles technically could be in the category of motorized bicycles but instead of using internal combustion engines as a combination it is driven by electric motors which power from pedals and batteries. ...

Pneumatic Tires
A tire (American English) or tyre (British English) is a ring-shaped component that surrounds a wheel's rim to transfer a vehicle's load from the axle through the wheel to the ground and to provide traction on the surface over which the wheel travels. Most tires, such as those for automobiles and bicycles, are pneumatically inflated structures, which also provide a flexible cushion that absorbs shock as the tire rolls over rough features on the surface. Tires provide a footprint, called a contact patch, that is designed to match the weight of the vehicle with the bearing strength of the surface that it rolls over by providing a bearing pressure that will not deform the surface excessively. The materials of modern pneumatic tires are synthetic rubber, natural rubber, fabric, and wire, along with carbon black and other chemical compounds. They consist of a tread and a body. The tread provides traction while the body provides containment for a quantity of compressed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paris–Bordeaux–Paris
The Paris–Bordeaux–Paris Trail race of June 1895 is sometimes called the "first motor race", although it did not fit modern competition where the fastest is the winner. It was a win for Émile Levassor, who came first after completing the 1,178km race in 48 hours, almost six hours before second place. However, the official winner was Paul Koechlin, who finished third in his Peugeot, exactly 11 hours slower than Levassor, but the official race regulations had been established for four-seater cars, while Levassor and runner-up Louis Rigoulot were driving two-seater cars. First race Paris–Bordeaux–Paris is sometimes called the first motorcar race in history or the "first motor race". The 1894 Paris–Rouen had been run over public roads as a contest (''concours'') not a race, and the fastest finisher, a steam-powered vehicle, was judged ineligible for the main prize. Émile Levassor finished first in the 1,178 km Paris–Bordeaux–Paris race, taking 48 hours and 48 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface 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 a ...

Bunsen Cell
The Bunsen cell is a zinc-carbon primary cell (colloquially called a "battery") composed of a zinc anode in dilute sulfuric acid separated by a porous pot from a carbon cathode in Nitric acid, nitric or chromic acid. Cell details The Bunsen cell is about 1.9 volts and arises from the following reaction: : Zn + H2SO4 + 2 HNO3 ZnSO4 + 2 H2O + 2 NO2(g) According to the reaction above, when 1 mole (unit), mole (or part) each of zinc and sulfuric acid react with 2 moles (or parts) of nitric acid, the resultant products formed are, 1 mole (or part) of zinc sulfate and 2 moles (or parts) each of water and nitrogen dioxide (gaseous, in the form of bubbles). The cell is named after its inventor, German chemist Robert Wilhelm Bunsen, who improved upon the Grove cell by replacing William Robert Grove, Grove's expensive platinum cathode with carbon in the form of pulverized coal and coke (fuel), coke. Like Grove's battery, Bunsen's emitted noxious fumes of nitrogen dioxide. Bunsen use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Induction Coil
An induction coil or "spark coil" (archaically known as an inductorium or Ruhmkorff coil after Heinrich Rühmkorff) is a type of electrical transformer used to produce high-voltage pulses from a low-voltage direct current (DC) supply. p.98 To create the flux changes necessary to induce voltage in the secondary coil, the direct current in the primary coil is repeatedly interrupted by a vibrating mechanical contact called an interrupter. Invented in 1836 by Nicholas Callan, with additional research by Charles Grafton Page and others, the induction coil was the first type of transformer. It was widely used in x-ray machines, spark-gap radio transmitters, arc lighting and quack medical electrotherapy devices from the 1880s to the 1920s. Today its only common use is as the ignition coils in internal combustion engines and in physics education to demonstrate induction. Construction and function An induction coil consists of two coils of insulated wire wound around a common i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Twistgrip
A twistgrip is a handle that can be twisted to operate a control. It is commonly found as a motorcycle's right handlebar grip to control the throttle, but is sometimes found elsewhere, such as on a bicycle as a gearshift, and in helicopters. History The first use of the twist grip throttle control was on the Roper steam velocipede of 1867-69. Rather than a sleeve that rotated around the handlebar, Sylvester H. Roper's steam motorcycle's entire handlebar rotated, with a dual mode operation. When rotated forward it opened the throttle, and when rotated backwards it applied the spoon brake. ''Motorcycle Consumer News'' design columnist Glynn Kerr said that pioneering this technology was a point in favor of the Roper's precedence as the first motorcycle, in response to ''Cycle World'' Technical Editor Kevin Cameron's position that the 1885 Daimler ''Reitwagen'' was more deserving because it used the more successful technology, internal combustion rather than steam. The design dra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
