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. The first V8 engine was produced by the French Antoinette company in 1904, developed and used in cars and speedboats but primarily aircraft; while the American 1914–1935 ''Cadillac L-Head'' engine is considered the first road going V8 engine to be mass produced in significant quantities. The popularity of V8 engines in cars was greatly increased following the 1932 introduction of the ''Ford Flathead V8''. In the early 21st century, use of V8 engines in passenger vehicles declined as automobile manufacturers opted for more fuel efficient, lower capacity engines, or hybrid and electric drivetrains. Design V-angle The majority of V8 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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chevrolet Small-block Engine - Automobile Driving Museum - El Segundo, CA - DSC01736
Chevrolet ( ), colloquially referred to as Chevy and formally the Chevrolet Motor Division of General Motors Company, is an American automobile division of the American manufacturer General Motors (GM). Louis Chevrolet (1878–1941) 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's second ousting in 1919, Alfred Sloan, with his maxim "a car for every purse and purpose", would pick the Chevrolet brand to become the volume leader in the General Motors family, selling mainstream vehicles to compete with Henry Ford's Model T in 1919 and overtaking Ford as the best-selling car in the United States by 1929 with the Chevrolet International. Chevrolet-branded vehicles are sold in most autom ... [...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 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.

Flat-plane Crank
The flat-plane crank (sometimes flatplane) is a type of crankshaft for use in internal combustion engines that has a 180 degree angle between crank throws. Details Flat-plane cranks are used in V-configuration engines, generally with eight cylinders. Cadillac introduced a V8 flat-plane crank engine in 1923. Inline-four cylinder engines almost all use flat-plane cranks, and thus are not usually identified as such. However, there are a few exceptions with crossplane cranks. The flat-plane crankshaft is a design that is no longer used in most mass production V engines as it is more prone to vibration and is inherently much louder than a crossplane crankshaft. However, due to its simpler construction requiring less counterweight, it is inherently lighter with a higher rev limit. For this reason, it remains useful in sports and racing cars. Flat-plane crankshafts are generally associated with European sports cars such as Ferrari and Lotus V8 engines, and cross-plane cr ...

Firing Order
The firing order of an internal combustion engine is the sequence of ignition for the cylinders. In a spark ignition (e.g. gasoline/petrol) engine, the firing order corresponds to the order in which the spark plugs are operated. In a diesel engine, the firing order corresponds to the order in which fuel is injected into each cylinder. Four-stroke engines must also time the valve openings relative to the firing order, as the valves do not open and close on every stroke. Firing order affects the vibration, sound and evenness of power output from the engine and heavily influences crankshaft design. Cylinder numbering Numbering systems for car engines The numbering system for cylinders is generally based on the cylinder numbers increasing from the front to the rear of an engine (See engine orientation below). However, there are differences between manufacturers in how this is applied; some commonly used systems are as listed below. ;Straight engine Cylinders numbered from front ...

Engine Balance
Engine balance refers to how the forces (resulting from combustion or rotating/reciprocating components) are balanced within an internal combustion engine or steam engine. The most commonly used terms are ''primary balance'' and ''secondary balance''. ''First-order balance'' and ''second-order balance'' are also used. Unbalanced forces within the engine can lead to vibrations. Causes of imbalance Although some components within the engine (such as the connecting rods) have complex motions, all motions can be separated into reciprocating and rotating components, which assists in the analysis of imbalances. Using the example of an inline engine (where the pistons are vertical), the main reciprocating motions are: * Pistons moving upwards/downwards * Connecting rods moving upwards/downwards * Connecting rods moving left/right as they rotate around the crankshaft, however the lateral vibrations caused by these movements are much smaller than the up–down vibrations caused by ...

Crossplane
The crossplane or cross-plane is a crankshaft design for piston engines with a 90° angle (phase in crank rotation) between the crank throws. The crossplane crankshaft is the most popular configuration used in V8 road cars. Aside from the V8 already mentioned, other examples of configurations using such 90° piston phases include straight-2, straight-4, V2, and V4 engines. Crossplane crankshafts could feasibly be used with a great many other cylinder configurations, but the advantages and disadvantages described below may not apply to any or all of them and must be considered on a case-by-case basis. Crossplane V8 crankshaft Design The most common crossplane crankshaft for a 90° V8 engine has four crankpins, each serving two cylinders on opposing banks, offset at 90° from the adjacent crankpins. The first and last of the four crank pins are at 180° with respect to each other as are the second and third, with each pair at 90° to the other, so that viewed from the end ...

EMD 567
The EMD 567 is a line of large medium-speed diesel engines built by General Motors' Electro-Motive Division. This engine, which succeeded Winton's 201A, was used in EMD's locomotives from 1938 until its replacement in 1966 by the EMD 645. It has a bore of , a stroke of and a displacement of per cylinder. Like the Winton 201A, the EMD 645 and the EMD 710, the EMD 567 is a two-stroke engine. GE now makes EMD-compatible replacement parts. History Eugene W. Kettering, son of Charles F. Kettering, joined Winton Engine in 1930. He moved to Detroit in 1936, and was a central figure in the development of the 567 and the Detroit Diesel 6-71. He moved to EMD in 1938, became Chief Engineer at EMD in 1948, then Division Director in 1956 and subsequently Research Assistant to the General Manager in 1958 until his retirement in 1960. The 567 was released in 1938.General Motors 567-C Engines ''Diesel Railway Traction'' November 1955 pages 325-332 In 1951, Eugene Kettering presente ...

Harry Miller (auto Racing)
Harold Arminius Miller (December 9, 1875 – May 3, 1943), commonly called Harry, was an American race car designer and builder who was most active in the 1920s and 1930s. Griffith Borgeson called him "the greatest creative figure in the history of the American racing car". Cars built by Miller won the Indianapolis 500 nine times, and other cars using his engines won three more. Millers accounted for 83% of the Indy 500 fields between 1923 and 1928. Biography Miller was born on December 9, 1875, in Menomonie, Wisconsin, to Jacob Miller (1833–1900) and Martha Ann (Tuttle) Miller (c1835–1922). Miller's first work in the automotive business was with the short-lived Yale Automobile Company. From Yale he moved to Lansing, Michigan, to work for motoring pioneer Ransom E. Olds at Oldsmobile, where he was employed as a race mechanic during the early Vanderbilt cup races. After a poor 1906 race season, Miller left for Los Angeles, California, to open a small machine shop speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.
