Four-stroke
A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: #Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum pressure into the cylinder through its downward motion. The piston is moving down as air is being sucked in by the downward motion against the piston. #Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves are close ...

Internal Combustion
An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons ( piston engine), turbine blades (gas turbine), a rotor (Wankel engine), or a nozzle ( jet engine). This force moves the component over a distance, transforming chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to. This replaced the external combustion engine for applications where the weight or size of an engine was more important. The first commercially successful internal combustion engine was created by Étienne Lenoir around 1860, and the first modern internal combustion engine, known a ...

Two-stroke Cycle
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one revolution of the crankshaft. A four-stroke engine requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions occurring at the same time. Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow range of rotational speeds called the power band. Two-stroke engines have fewer moving parts than four-stroke engines. History The first commercial two-stroke engine involving cylinder compression is attributed to Scottish engineer Dugald Clerk, who patented his design in 1881. However, unlike most later two-st ...

Nicolaus Otto
Nicolaus August Otto (10 June 1832, Holzhausen an der Haide, Nassau – 26 January 1891, Cologne) was a German engineer who successfully developed the compressed charge internal combustion engine which ran on petroleum gas and led to the modern internal combustion engine. The Association of German Engineers (VDI) created DIN standard 1940 which says "Otto Engine: internal combustion engine in which the ignition of the compressed fuel-air mixture is initiated by a timed spark", which has been applied to all engines of this type since. Biography Nicolaus August Otto was born on 10 June 1832 in Holzhausen an der Haide, Germany. He was the youngest of six children. His father died in 1832. He began school in 1838. After six years of good performance he moved to the high school in Langenschwalbach until 1848. He did not complete his studies but was cited for good performance. His main interest in school had been in science and technology but he graduated after three years as a bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daimler-Motoren-Gesellschaft
Daimler-Motoren-Gesellschaft (abbreviated as DMG, also known as ''Daimler Motors Corporation'') was a German engineering company and later automobile manufacturer, in operation from 1890 until 1926. Founded by Gottlieb Daimler (1834–1900) and Wilhelm Maybach (1846–1929), it was based first in Cannstatt (today Bad Cannstatt, a city district of Stuttgart). Daimler died in 1900, and their business moved in 1903 to Stuttgart-Untertürkheim after the original factory was destroyed by fire, and again to Berlin in 1922. Other factories were located in Marienfelde (near Berlin) and Sindelfingen (next to Stuttgart). The enterprise began to produce petrol engines but after the success of a small number of race cars built on contract by Wilhelm Maybach for Emil Jellinek, it began to produce the '' Mercedes'' model of 1902. After this automobile production expanded to become ''DMG'''s main product, and it built several models. Because of the post World War One German economic crisis, '' ...

T Cycle AtkinsonMiller
T, or t, is the twentieth letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''tee'' (pronounced ), plural ''tees''. It is derived from the Semitic Taw 𐤕 of the Phoenician and Paleo-Hebrew script (Aramaic and Hebrew Taw ת/𐡕/, Syriac Taw ܬ, and Arabic ت Tāʼ) via the Greek letter τ (tau). In English, it is most commonly used to represent the voiceless alveolar plosive, a sound it also denotes in the International Phonetic Alphabet. It is the most commonly used consonant and the second most commonly used letter in English-language texts. History '' Taw'' was the last letter of the Western Semitic and Hebrew alphabets. The sound value of Semitic ''Taw'', Greek alphabet Tαυ (''Tau''), Old Italic and Latin T has remained fairly constant, representing in each of these; and it has also kept its original basic shape in most of these alphabets.

Deutz, Cologne
The Cologne borough of Deutz (german: Köln-Deutz ; ), is a part of central Cologne, Germany, and was once an independent town. History Deutz was established under Roman Emperor Constantine I in 310 AD, when he established ''Castrum Divitia'', a military camp built on the banks of the Rhine across from Colonia Claudia Ara Agrippinensium. Camp and city were linked via a bridge from the same time. During the Middle Ages, Deutz was an important centre of learning in medieval Germany. Up into the early Middle Ages it was known by the Latin name ''Divitia'', from the 10th century as ''Tuitium''. It was located on the right bank of the Rhine, opposite Cologne, which grew up on the left bank. In 1002, the old castle in Deutz was made a Benedictine monastery by Heribert, archbishop of Cologne, and the important abbey was home to many influential theologians, such as Rupert of Deutz. Permission to fortify the town was in 1230 granted to the citizens by the archbishop of Cologne, between ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Atkinson (inventor)
James Atkinson (1846 – 1914) of Hampstead was a British engineer who invented several engines with greater efficiency than the Otto cycle. The Atkinson cycle engines were named the "Differential 1882", "Cycle 1887" and "Utilite 1892". The most well-known of Atkinson's engines is the "Cycle 1887", patented in 1887. By use of variable engine strokes from a complex crankshaft, Atkinson was able to increase the efficiency of his engine, at the cost of some power, over traditional Otto-cycle engines. He was awarded the John Scott Medal of The Franklin Institute in 1889. See also *History of the internal combustion engine Various scientists and engineers contributed to the development of internal combustion engines.

Karl Benz
Carl Friedrich Benz (; 25 November 1844 – 4 April 1929), sometimes also Karl Friedrich Benz, was a German engine designer and automotive engineer. His Benz Patent Motorcar from 1885 is considered the first practical modern automobile and first car put into series production. He received a patent for the motorcar in 1886. His company Benz & Cie., based in Mannheim, was the world's first automobile plant and largest of its day. In 1926 it merged with Daimler Motoren Gesellschaft to form Daimler-Benz which produces the Mercedes-Benz among other brands. Benz is widely regarded as "the father of the car" and "father of the automobile industry". Early life Carl Benz was born Karl Friedrich Michael Vaillant, on 25 November 1844 in Mühlburg, now a borough of Karlsruhe, Baden-Württemberg, which is part of modern Germany. His parents were Josephine Vaillant and a locomotive driver, Johann Georg Benz, whom she married a few months later. According to German law, the child acquired ...

Daimler Reitwagen
The Daimler ''Reitwagen'' ("riding car") or ''Einspur'' ("single track") was a motor vehicle made by Gottlieb Daimler and Wilhelm Maybach in 1885. It is widely recognized as the first motorcycle. Daimler is often called "the father of the motorcycle" for this invention. Even when the steam powered two-wheelers that preceded the ''Reitwagen'', the Michaux-Perreaux and Roper of 1867–1869, and the 1884 Copeland, are considered motorcycles, it remains nonetheless the first gasoline internal combustion motorcycle, and the forerunner of all vehicles, land, sea and air, that use its overwhelmingly popular engine type. First motorcycle? The ''Reitwagen''s status as the first motorcycle rests on whether the definition of motorcycle includes having an internal combustion engine. The ''Oxford English Dictionary'' uses this criterion. Even by that definition, the use of four wheels instead of two raises doubts. If the outriggers are accepted as auxiliary stabilizers, they point to a de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
