Straight-eight Engines
The straight-eight engine or inline-eight engine (often abbreviated as I8) is an eight-cylinder internal combustion engine with all eight cylinder (engine), cylinders mounted in a straight line along the crankcase. The type has been produced in side-valve, IOE engine, IOE, overhead-valve, sleeve-valve, and overhead-cam configurations. A straight-eight can be timed for engine balance#Inherent mechanical balance, inherent primary and secondary balance, with no unbalanced primary or secondary forces or moments. However, crankshaft torsional vibration, present to some degree in all engines, is sufficient to require the use of a harmonic damper at the accessory end of the crankshaft. Without such damping, fatigue (material), fatigue cracking near the rear main bearing journal (mechanical device), journal may occur, leading to engine failure. Although an inline-six engine, inline six-cylinder engine can also be timed for inherent primary and secondary balance, a straight-eight devel ...

Delage Engine
Delage is a French luxury automobile and racecar company founded in 1905 by Louis Delâge in Levallois-Perret near Paris; it was acquired by Delahaye in 1935 and ceased operation in 1953. On 7 November 2019, the association "Les Amis de Delage" created in 1956 and owner of the Delage brand, announced the re-founding of the company Delage Automobiles with the Delage D12. Early history The company was founded in 1905 by Louis Delâge, who borrowed French franc, Fr 35,000, giving up a salary of F 600 a month to do so.#PH1, Hull, p. 517. Its first location was on the Rue Cormeilles in Levallois-Perret. The company at first had just two lathes and three employees, one of them Peugeot's former chief designer. Delage initially produced parts for Helbé, with the De Dion-Bouton engine and chassis assembled by Helbé; Delage added only the body. The first model was the Delage Type A, Type A, a ''voiturette'' which appeared in 1906. It was powered by a one-cylinder De Dion-Bouton of . ...

Inline-six Engine
A straight-six engine (also referred to as an inline-six engine; abbreviated I6 or L6) is a piston engine with six cylinders arranged in a straight line along the crankshaft. A straight-six engine has perfect primary and secondary engine balance, resulting in fewer vibrations than other designs of six or fewer cylinders. Until the mid-20th century, the straight-six layout was the most common design for engines with six cylinders. However, V6 engines gradually became more common in the 1970s and by the 2000s, V6 engines had replaced straight-six engines in most light automotive applications. Characteristics In terms of packaging, straight-six engines are almost always narrower than a V6 engine or V8 engine, but longer than straight-four engines, V6s, and most V8s. Compared to V-configuration engines with similar power and displacement, the straight configuration has fewer injectors, a single head, and a single exhaust manifold, all contributing to better reliability and pe ...

De Dion-Bouton
De Dion-Bouton was a French automobile manufacturer and railcar manufacturer, which operated from 1883 to 1953. The company was founded by the Marquis Jules-Albert de Dion, Georges Bouton, and Bouton's brother-in-law Charles Trépardoux. Steam cars The company was formed in 1883 after de Dion saw a toy locomotive in a store window in 1881 and asked the toymakers to build another. Engineers Bouton and Trépardoux had been eking out a living with scientific toys at a shop in the Passage de Léon, near the rue de la Chapelle in Paris.Wise, p. 510. Trépardoux had long dreamed of building a steam car, but neither he nor Bouton could afford it. De Dion, already inspired by steam in the form of railway locomotives,Georgano, p. 27. and with ample money, agreed to back them, and Trépardoux et Cie was formed in Paris in 1883. That became the De Dion-Bouton automobile company, the world's largest automobile manufacturer for a time, well known for the quality, reliability, and du ...

Aerodynamics
Aerodynamics () is the study of the motion of atmosphere of Earth, air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics, and is an important domain of study in aeronautics. The term ''aerodynamics'' is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving Aircraft#Heavier-than-air – aerodynes, heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer si ...

Mercedes (car)
Mercedes () was a brand originally created by the Daimler-Motoren-Gesellschaft (DMG) and used for first time in the 35 hp model released by the company in 1901. DMG began to develop in 1900, after the death of its co-founder, Gottlieb Daimler. Although the name was not lodged as a trade name until 23 June 1902 and not registered legally until 26 September, the brand name eventually would be applied to an automobile model built by Wilhelm Maybach to specifications by Emil Jellinek. This vehicle was delivered to him on 22 December 1900. By Jellinek's contract, the new model contained a newly designed engine designated "Daimler-Mercedes". This engine name is the first instance of the use of the name Mercedes by DMG. The automobile design would later be called the ''Mercedes 35 hp''. When DMG merged with Benz & Cie to form "Daimler-Benz" in 1926, the new company became owner of the ''Mercedes'' brand name. Overview Emil Jellinek was an Austrian-Jewish diplomat based in Nice w ...

Charron, Girardot Et Voigt
Charron was a French automobile manufacturer, based in the Paris conurbation, and active between 1906 and 1930. Although the company Automobiles Charron Limited was established (with a large injection of British finance) only in 1906 (and registered in 1907), its origins date from a business founded in 1901 called Automobiles Charron, Girardot et Voigt (C.G.V.). Fernand Charron Fernand Charron was born in 1866. Before turning his attention to automobiles, through the 1890s, he was a leading racing cyclist. However, he then became a successful racing driver, with several wins, driving a Panhard, during 1898. Automobiles Charron, Girardot et Voigt (CGV) Automobiles Charron, Girardot & Voigt SA (trade mark C.G.V.) was a French motor manufacturer founded by the racing cyclists and motorists Fernand Charron, Léonce Girardot and Émile Voigt. It was based at 7 rue Ampère in Puteaux, approximately from the central Paris. They opened one of the first French car dealershi ...

V8 Engine
A V8 engine is an eight- cylinder piston engine in which two banks of four cylinders share a common crankshaft and are arranged in a V configuration. Origins The first known V8 was the Antoinette, designed by Léon Levavasseur, and built in 1904 by the French Antoinette company for use in speedboat racing, cars, and later, airplanes. Also in 1904, V8 engines began small-scale production by Renault and Buchet for use in race cars. Design V-angle Most engines use a V-angle (the angle between the two banks of cylinders) of 90 degrees. This angle results in good engine balance, which results in low vibrations. However, the downside is the greater width of the engine compared to those that use a smaller V-angle. V8 engines with a 60-degree V-angle were used in the 1996–1999 Ford Taurus SHO, the 2005–2011 Volvo XC90, and the 2006–2009 Volvo S80. The Ford engine used a 60-degree V-angle because it was based on a V6 engine with a 60-degree V-angle. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Connecting Rod
A connecting rod, also called a 'con rod', is the part of a reciprocating engine, piston engine which connects the piston to the crankshaft. Together with the crank (mechanism), crank, the connecting rod converts the reciprocating motion of the piston into the rotation of the crankshaft. The connecting rod is required to transmit the compressive and tensile forces from the piston. In its most common form, in an internal combustion engine, it allows pivoting on the piston end and rotation on the shaft end. The predecessor to the connecting rod is a mechanic linkage used by water mills to convert rotating motion of the water wheel into reciprocating motion. The most common usage of connecting rods is in internal combustion engines or on steam engines. __TOC__ Origins A connecting rod crank has been found in the Celtic Oppida at Paule in Brittany, dated to 69 BC. The predecessor to the connecting length is the Linkage (mechanical), mechanical linkage used by List of Roman wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Revolutions Per Minute
Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or r⋅min−1) is a unit of rotational speed (or rotational frequency) for rotating machines. One revolution per minute is equivalent to hertz. Standards ISO 80000-3:2019 defines a physical quantity called ''rotation'' (or ''number of revolutions''), dimensionless, whose instantaneous rate of change is called ''rotational frequency'' (or ''rate of rotation''), with units of reciprocal seconds (s−1). A related but distinct quantity for describing rotation is ''angular frequency'' (or ''angular speed'', the magnitude of angular velocity), for which the SI unit is the radian per second (rad/s). Although they have the same dimensions (reciprocal time) and base unit (s−1), the hertz (Hz) and radians per second (rad/s) are special names used to express two different but proportional ISQ quantities: frequency and angular frequency, respectively. The conversions between a frequency and an angular frequency ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
