Étienne Lenoir
Jean Joseph Étienne Lenoir, also known as Jean J. Lenoir (12 January 1822 – 4 August 1900), was a Belgian-French engineer who invented the internal combustion engine in 1858. Prior designs for such engines were patented as early as 1807 (De Rivaz engine) and 1854 (Barsanti–Matteucci engine). He was born in Mussy-la-Ville (then in Luxembourg, part of the Belgian Luxembourg (Belgium), Province of Luxembourg since 1839). In 1838, he immigrated to France, taking up residence in Paris, where he developed an interest in electroplating. His interest in the subject led him to make several electrical inventions, including an improved electric telegraph. Lenoir engine By 1859, Lenoir's experimentation with electricity led him to develop the first internal combustion engine which burned a mixture of coal gas and air ignited by a "jumping sparks" ignition system by Induction coil, Ruhmkorff coil, and which he patented in 1860. The engine was a steam engine converted to burn gaseous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Double-acting Cylinder
In mechanical engineering, the Cylinder (engine), cylinders of reciprocating engines are often classified by whether they are single- or double-acting, depending on how the working fluid acts on the piston. Single-acting A single-acting cylinder in a reciprocating engine is a cylinder (engine), cylinder in which the working fluid acts on one side of the piston only. A single-acting cylinder relies on the load, springs, other cylinders, or the momentum of a flywheel, to push the piston back in the other direction. Single-acting cylinders are found in most kinds of reciprocating engine. They are almost universal in internal combustion engines (e.g. petrol engine, petrol and diesel engines) and are also used in many external combustion engines such as Stirling engines and some steam engines. They are also found in pumps and hydraulic cylinder, hydraulic rams. Double-acting A double-acting cylinder is a cylinder in which the working fluid acts alternately on both sides of the pi ...

Alexander II Of Russia
Alexander II ( rus, Алекса́ндр II Никола́евич, Aleksándr II Nikoláyevich, p=ɐlʲɪˈksandr ftɐˈroj nʲɪkɐˈlajɪvʲɪtɕ; 29 April 181813 March 1881) was Emperor of Russia, Congress Poland, King of Poland and Grand Duke of Finland from 2 March 1855 until Assassination of Alexander II of Russia, his assassination in 1881. Alexander's most significant reform as emperor was the emancipation reform of 1861, emancipation of Serfdom in Russia, Russia's serfs in 1861, for which he is known as Alexander the Liberator ( rus, Алекса́ндр Освободи́тель, r=Aleksándr Osvobodítel, p=ɐlʲɪˈksandr ɐsvəbɐˈdʲitʲɪlʲ). The tsar was responsible for other Liberalism, liberal reforms, including reorganizing the judicial system, setting up elected local judges, abolishing corporal punishment, promoting local self-government through the ''zemstvo'' system, imposing universal military service, ending some privileges of the nobility, and promot ...

Tsar
Tsar (; also spelled ''czar'', ''tzar'', or ''csar''; ; ; sr-Cyrl-Latn, цар, car) is a title historically used by Slavic monarchs. The term is derived from the Latin word '' caesar'', which was intended to mean ''emperor'' in the European medieval sense of the term—a ruler with the same rank as a Roman emperor, holding it by the approval of another emperor or a supreme ecclesiastical official—but was usually considered by Western Europeans to be equivalent to "king". Tsar and its variants were the official titles in the First Bulgarian Empire (681–1018), Second Bulgarian Empire (1185–1396), the Kingdom of Bulgaria (1908–1946), the Serbian Empire (1346–1371), and the Tsardom of Russia (1547–1721). The first ruler to adopt the title ''tsar'' was Simeon I of Bulgaria. Simeon II, the last tsar of Bulgaria, is the last person to have held this title. Meaning in Slavic languages The title tsar is derived from the Latin title for the Roman emperors, ''c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carburettor
A carburetor (also spelled carburettor or carburetter) is a device used by a gasoline 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 effect or Bernoulli's principle or with a Pitot tube in the main metering circuit, though 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, but carburetors are still used by some small engines (e.g. lawnmowers, generators, and concrete mixers) and motorcycles. In addition, they are still widely used on piston-engine–driven aircraft. Diesel engines have always used fuel injection instead of carburetors, as the compression-based combustion of diesel requires the greater precision and pressure of fuel injection. Etymology The term ''carburetor'' is derived from the verb ''carburet'', which means ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petroleum
Petroleum, also known as crude oil or simply oil, is a naturally occurring, yellowish-black liquid chemical mixture found in geological formations, consisting mainly of hydrocarbons. The term ''petroleum'' refers both to naturally occurring unprocessed crude oil, as well as to petroleum products that consist of refining, refined crude oil. Petroleum is a fossil fuel formed over millions of years from anaerobic decay of organic materials from buried prehistoric life, prehistoric organisms, particularly planktons and algae, and 70% of the world's oil deposits were formed during the Mesozoic. Conventional reserves of petroleum are primarily recovered by oil drilling, drilling, which is done after a study of the relevant structural geology, sedimentary basin analysis, analysis of the sedimentary basin, and reservoir characterization, characterization of the petroleum reservoir. There are also unconventional (oil & gas) reservoir, unconventional reserves such as oil sands and oil sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

French Franc
The franc (; , ; currency sign, sign: F or Fr), also commonly distinguished as the (FF), was a currency of France. Between 1360 and 1641, it was the name of coins worth 1 livre tournois and it remained in common parlance as a term for this amount of money. It was reintroduced (in French livre, decimal form) in 1795. After two centuries of inflation, it was Redenomination, redenominated in 1960, with each (NF) being worth 100 old francs. The NF designation was continued for a few years before the currency returned to being simply the franc. Many French residents, though, continued to quote prices of especially expensive items in terms of the old franc (equivalent to the new centime), up to and even after the introduction of the euro (for coins and banknotes) in 2002. The French franc was a commonly held international reserve currency of reference in the 19th and 20th centuries. Between 1998 and 2002, the conversion of francs to euros was carried out at a rate of 6.55957 franc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
