W3 Engine
A W engine is a type of piston engine where three or four cylinder banks use the same crankshaft, resembling the letter W when viewed from the front. W engines with three banks of cylinders are also called "broad arrow" engines, due to their shape resembling the British government broad arrow property mark. W engines are less common than V engines. Compared with a V engine, a W engine is typically shorter and wider. W3 engines One of the first W engines was the Anzani 3-cylinder, built in 1906, to be used in Anzani motorcycles. It is this W3 engine which also powered the 1909 Blériot XI, the first airplane to fly across the English Channel. The ''Feuling W3'' is a motorcycle engine that was built by an aftermarket parts company in the United States in the early 2000s. Like radial aircraft engines it has a master connecting rod and two slave rods connected to the pistons. W6 engines The Rumpler Tropfenwagen had a Siemens and Halske-built overhead valve W6 engine, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Volkswagen Group Petrol Engines
The spark-ignition petrol engines listed below operate on the four-stroke cycle, and unless stated otherwise, use a wet sump lubrication system, and are water-cooled.ETKA official factory data Since the Volkswagen Group is German, official internal combustion engine performance ratings are published using the International System of Units (commonly abbreviated "SI"), a modern form of the metric system of figures. Motor vehicle engines will have been tested by a Deutsches Institut für Normung (DIN) accredited testing facility, to either the original '' 80/1269/EEC'', or the later ''1999/99/ EC'' standards. The standard initial measuring unit for establishing the rated motive power output is the kilowatt (kW); and in their official literature, the power rating may be published in either the kW, or the metric horsepower (often abbreviated "PS" for the German word ''Pferdestärke''), or both, and may also include conversions to imperial units such as the horsepower (hp) or bra ...

VR6 Engine
VR6 engines are V6 piston engines with a narrow angle between the cylinder banks and a single cylinder head covering both banks of cylinders. Volkswagen Group introduced the first VR6 engine in 1991 and VR6 engines currently remain in production. From 1997 to 2006, Volkswagen also produced a five-cylinder VR5 engine based on the VR6. Description The name VR6 comes from the German initials for a V engine (German: ''V-Motor'') and a straight (inline) engine (German: ''Reihenmotor''), therefore the VR engine is described as a "Vee-Inline engine" (VR-Motor). VR6 engines share a common cylinder head for the two banks of cylinders. Only two camshafts are needed for the engine, regardless of whether the engine has two or four valves per cylinder. This simplifies engine construction and reduces costs. Since the cylinders are not located on the centreline of the combined cylinder head, the lengths of the intake and exhaust ports are different for each bank. Without compensation, ...

Western Front (World War II)
The Western Front was a European theatre of World War II, military theatre of World War II encompassing Denmark, Norway, Luxembourg, Belgium, Netherlands, the Netherlands, the United Kingdom, France, and Germany. The Italian campaign (World War II), Italian front is considered a separate but related theater. The Western Front's 1944-1945 phase was officially deemed the European Theater of Operations, United States Army, European Theater by the United States, whereas Italy fell under the Mediterranean Theater of Operations, United States Army, Mediterranean Theater along with North Africa. The Western Front was marked by two phases of large-scale combat operations. The first phase saw the capitulation of Luxembourg, Netherlands, Belgium, and France during May and June 1940 after their defeat in the Low Countries and the northern half of France, and continued into an air war between Germany and Britain that climaxed with the Battle of Britain. The second phase consisted of large- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M4 Sherman
} The M4 Sherman, officially Medium Tank, M4, was the most widely used medium tank by the Military history of the United States during World War II, United States and Allies of World War II, Western Allies in World War II. The M4 Sherman proved to be reliable, relatively cheap to produce, and available in great numbers. It was also the basis of several other Armoured_fighting_vehicle, armored fighting vehicles including self-propelled artillery, Tank_destroyer, tank destroyers, and Armoured_recovery_vehicle, armored recovery vehicles. Tens of thousands were distributed through the Lend-Lease program to the British Empire#Second World War, British Commonwealth and Soviet Union. The tank was named by the British after the American Civil War General William Tecumseh Sherman. The M4 Sherman evolved from the M3 Lee, M3 Medium Tank, which for speed of development had its main armament in a side sponson mount. The M4 retained much of the previous mechanical design, but moved the 75_mm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M3 Lee
The M3 Lee, officially Medium Tank, M3, was an American medium tank used during World War II. The turret was produced in two forms, one for US needs and one modified to British requirements to place the radio next to the commander. In British Commonwealth service, the tank was called by two names: tanks employing US pattern turrets were called "Lee," named after Confederate general Robert E. Lee, while those with British pattern turrets were known as "Grant," named after Union general Ulysses S. Grant. Design commenced in July 1940, and the first M3s were operational in late 1941. The US Army needed a medium tank armed with a 75mm gun and, coupled with the United Kingdom's immediate demand for 3,650 medium tanks, the Lee began production by late 1940. The design was a compromise meant to produce a tank as soon as possible. The M3 had considerable firepower and good armor, but had serious drawbacks in its general design and shape, including a high silhouette, an archaic sponson ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chrysler Flathead Engine
The Chrysler flathead engine is a Sidevalve engine, flathead automotive engine manufactured by the Chrysler Corporation from 1924 through the early 1960s. The flathead engine came in four-,six-, and eight-cylinder configurations and varying displacement, with both a cast iron and cast aluminum cylinder head. It was installed in Chrysler, DeSoto, Dodge and Plymouth branded vehicles. Straight-4 Chrysler introduced a Inline-four engine, straight-four derivative of their new flathead Straight-six engine, straight-six in 1926. Initially used by Chrysler, the straight-four was fitted to Plymouth (automobile), Plymouth and Dodge light trucks beginning in 1929, lasting in production through 1933. The original version displaced and produced 38 hp (28 kW). This was only produced in 1926, with displacement reduced to for 1927 and 1928. Power was initially rated the same but was upped to 45 hp (34 kW) during the 1928 model year. After the introduction of the Plymouth br ...

Chrysler A57 Multibank
The Chrysler A57 Multibank is a 30-cylinder engine that was created in 1941 as America entered World War II. It consists of five banks of inline-6 cylinder engines. It was born out of the necessity for a rear-mounted tank engine to be developed and produced in the shortest time possible for use in the M3A4 Lee medium tank and its successor M4A4 Sherman medium tank. Each had lengthened hulls to accommodate the A57. In order to use existing tooling, five Chrysler flathead engines (bore , stroke ) were arranged around a central shaft, producing a unique 30-cylinder engine in a relatively compact but heavy package. The combined assembly consisted of five of these straight-six engines mounted in a pseudo-radial fashion upon a central cast-iron crankcase. The arrangement employed a common radiator, water pump, oil pan & dual oil pumps, with each of the five component crankshafts fitted with a geared flywheel that meshed with a central sun gear that drove a main shaft running thr ...

Allison Engine Company
The Allison Engine Company was an American aircraft engine manufacturer. Shortly after the death of James A. Allison, James Allison in 1929 the company was purchased by the Fisher Body, Fisher brothers. Fisher sold the company to General Motors, which owned it for most of its history. It was acquired by Rolls-Royce Holdings, Rolls-Royce plc in 1995 to become the US subsidiary, Rolls-Royce North America. History A predecessor of Allison Engine Company, the Concentrated Acetylene Company, was founded in September 1904 by James Allison, Percy C. Avery, Percy C. "Fred" Avery and Carl G. Fisher. Avery was the holder of the patent for the product. This company was the predecessor of the Prest-O-Lite, Prest-O-Lite Company, a manufacturer of acetylene headlights. An explosion at the acetylene gas works in downtown Indianapolis caused the company to relocate out of town, near the race track in Speedway, Indiana. Allison and Fisher raced automobiles at that track, each owning a race car t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allison V-3420
The Allison V-3420 was a large experimental piston aircraft engine, designed in 1937 by the American Allison Engine Company. Design and development In 1937, at the behest of the United States Army Air Corps, the Allison Engine Company agreed to design and build a large-displacement high-power aircraft engine. The resulting V-3420 was essentially a pair of 12-cylinder Allison V-1710 engines mated to a common crankcase with a 30° angle between the inner cylinder banks. The crankshafts of the two V-1710 engines were geared together to drive a common propeller shaft. Most V-3420 parts were interchangeable with those for V-1710-E and -F engines. The V-3420 had a power-to-weight ratio of 1.6 kW/kg or 1 hp/lb, excellent for its time. It was envisioned as a powerful yet compact engine for several advanced USAAF projects of the day, including the Douglas XB-19, the Boeing XB-39 Superfortress, the Lockheed XP-58 Chain Lightning, and the Fisher P-75 Eagle.
