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] |
Chevrolet Small-block Engine - Automobile Driving Museum - El Segundo, CA - DSC01736
Chevrolet ( ) is an American automobile division of the manufacturer General Motors (GM). In North America, Chevrolet produces and sells a wide range of vehicles, from subcompact automobiles to medium-duty commercial trucks. Due to the prominence and name recognition of Chevrolet as one of General Motors' global marques, "Chevrolet" or its affectionate nickname 'Chevy' or is used at times as a synonym for General Motors or its products, one example being the GM LS1 engine, commonly known by the name or a variant thereof of its progenitor, the Chevrolet small-block engine. Louis Chevrolet (1878–1941), Arthur Chevrolet (1884–1946) and ousted General Motors founder William C. Durant (1861–1947) started the company on November 3, 1911 as the Chevrolet Motor Car Company. Durant used the Chevrolet Motor Car Company to acquire a controlling stake in General Motors with a reverse merger occurring on May 2, 1918, and propelled himself back to the GM presidency. After Durant' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lancia V4 Engine
Italian automobile company Lancia was the first to manufacture cars with V4 engine, V4 and V6 engine, V6 engines in series-production. This started with a number of V4-engine families, that were produced from the 1920s through 1970s. The Lancia V4 pioneered the narrow-angle V engine design, more recently seen in Volkswagen's VR5 engine, VR5 and VR6 engine, VR6 engines. By using very shallow V-angles — between 10° and 20° — both rows of cylinders could be housed in an engine block with a single cylinder head, like a straight engine. A determining characteristic was the use of overhead camshafts (either single or double), in which a camshaft would serve the same function for all cylinders — in ''both'' cylinder banks. Lambda The first V4 was used in the Lancia Lambda, Lambda from 1922 through 1931. It was a 20° narrow-angle aluminium design. All three engine displacements shared the same long stroke, and all were SOHC designs with a single camshaft serving both banks of c ...

Lancia Astura
The Lancia Astura is a passenger car produced by Italian automobile manufacturer Lancia between 1931 and 1939. Lancia replaced the Lambda model with two models: the four-cylinder Artena and the larger, V8-powered Astura. Both of these models were introduced at the Paris Motor Show in 1931. The Astura chassis was used by various coachbuilders to create coupes, convertibles and sedans. The Astura evolved over four series: * First series, built between 1931 and 1932 with 496 units made. * Second series, built between 1932 and 1933 with 750 units made. The engine mountings were modified for this generation to reduce noise and vibration. * Third series, built between 1933 and 1937 with 1,243 units made. The third-generation Astura was offered in short-wheelbase and long-wheelbase variants, and was powered by a new, larger engine. * Fourth series, built between 1937 and 1939 with 423 units made. Only offered in long-wheelbase. Engines First- and second-generation Asturas are powered by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lancia Dilambda
The Lancia Dilambda is a passenger car produced by Lancia between 1928 and 1935. The car was officially presented at the Paris Motor Show in 1929, and was powered by a 4 litre V8 engine with a 24 degree "V" angle. Three versions of the Dilambda were built: * First series, produced between 1928 and 1931, total 1,104 built. * Second series, produced between 1931 and 1933, total 300 built.

Lancia Trikappa
The Lancia Trikappa is an automobile produced by Lancia between 1922 and 1925. It was a luxury car, offered as the flagship of Lancia's production. The Trikappa 4.5-litre V8 is notable as the first of Lancia's narrow V engines, a distinguishing feature the manufacturer only abandoned in the 1970s. The car was offered as a bare rolling chassis, as torpedo or 6-seater coupé de ville. In total 847 were manufactured. Lancia had been experimenting with V engines since the First World War, even showcasing a chassis with a narrow V 12-cylinder engine at the 1919 Paris Motor Show. In the end V12 engined cars were estimated to be too expensive to produce and a V8 was used instead. Specifications The Trikappa was powered by a 4,594 cc ''Tipo 68'' V8, with a bore and stroke of and . The engine featured a narrow 14° angle between the cylinder banks, and a single overhead camshaft and two parallel valves per cylinder.

Rolls-Royce Merlin
The Rolls-Royce Merlin is a British Coolant#Liquids, liquid-cooled V12 engine, V-12 Reciprocating engine, piston aero engine of 27-litre (1,650 cu in) Engine displacement, capacity. Rolls-Royce Limited, Rolls-Royce designed the engine and first ran it in 1933 as a private venture. Initially known as the PV-12, it was later called ''Merlin (bird), Merlin'' following the company convention of naming its four-stroke piston aero engines after birds of prey. The engine benefitted from the racing experiences of precursor engines in the 1930s. After several modifications, the first production variants of the PV-12 were completed in 1936. The first operational aircraft to enter service using the Merlin were the Fairey Battle, Hawker Hurricane and Supermarine Spitfire. The Merlin remains most closely associated with the Spitfire and Hurricane, although the majority of the production run was for the four-engined Avro Lancaster heavy bomber. The Merlin continued to benefit from a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rolls-Royce Meteor
The Rolls-Royce Meteor later renamed the Rover Meteor is a British tank engine that was developed during the Second World War. It was used in British tanks up to 1964. It was a result of co-operation between Leyland Motors and Rolls-Royce who between them in 1941 had suggested that a specialised de-rated version of the Merlin aero-engine would be highly suitable for use in armoured fighting vehicles. The Meteor was developed from the Merlin by W. A. Robotham and his chassis design and development division at Clan Foundry, Belper, as they were not involved in aero-engine work and his engineers were under-used. With the aid of engineers from Leyland, who were engaged in tank work, he considered RR's two V12s; the Kestrel, while having more power than the existing "Liberty" or Meadows engines, did not provide the desirable 20 bhp per ton (producing only 475 bhp on "pool" petrol) required, so the 1,030 bhp (770 kW) Merlin III was chosen. Also, the Merlin was b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rolls-Royce Meteorite
The Rolls-Royce Meteorite, also known as the Rover Meteorite, was a post-war British V8 petrol or diesel engine was derived from the Rolls-Royce Meteor tank engine. Development In 1940 William Robotham who led a chassis design and development division at Clan Foundry in Belper, and Henry Spurrier, a director Leyland Motors, began investigating the use of Rolls-Royce aero engines as tank power-plants. Both men felt that continued use of the War Office's preferred Nuffied Liberty to be a retrograde step in the development of British tanks. The Liberty had been designed in 1917 and by this time was only able to produce a maximum power output of . Their requirements were the engine had to fit into the same engine compartment as the Liberty, and their aspiration was it would offer a power-to-weight ratio of for the proposed British tank designs. Initially Robotham and Spurrier investigated the use of a naturally aspirated version of the Rolls-Royce Kestrel engine. The Kestrel ...

Crankpin
A crankpin or crank pin, also known as a rod bearing journal, is a mechanical device in an engine which connects the crankshaft to the connecting rod for each cylinder. It has a cylindrical surface, to allow the crankpin to rotate relative to the "big end" of the connecting rod. The most common configuration is for a crankpin to serve one cylinder. However, many V engines have each crankpin shared by each pair of cylinders. Design The crankpin connects to the larger end of the connecting rod for each cylinder. This end of the connecting rod is called the "big end", as opposed to the "small end" or "little end" (which connects to the wrist/gudgeon pin in the piston). The bearing which allows the crankpin to rotate around its shaft is called the "rod bearing". In automotive engines, the most common type of rod bearing is the plain bearing, however bushings or roller bearings are also used in some engines. Configurations In a single-cylinder engine, straight engine or fla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Balance Shaft
Balance shafts are used in piston engines to reduce vibration by cancelling out unbalanced dynamic forces. The counter balance shafts have eccentric weights and rotate in the opposite direction to each other, which generates a net vertical force. The balance shaft was invented and patented by British engineer Frederick W. Lanchester in 1907. It is most commonly used in inline-four and V6 engines used in automobiles and motorcycles. Overview The operating principle of a balance shaft system is that two shafts carrying identical eccentric weights rotate in opposite directions at twice the engine speed. The phasing of the shafts is such that the centrifugal forces produced by the weights cancel the vertical second-order forces (at twice the engine RPM) produced by the engine. The horizontal forces produced by the balance shafts are equal and opposite, and so cancel each other. The balance shafts do not reduce the vibrations experienced by the crankshaft.
