Mercedes D.IIIav
The Mercedes D.III, or F1466 as it was known internally, was a six-cylinder SOHC valvetrain liquid-cooled Straight-six engine, inline aircraft engine built by Daimler Motoren Gesellschaft, Daimler and used on a wide variety of German aircraft during World War I. The initial versions were introduced in 1914 at , but a series of changes improved this to in 1917, and by mid-1918. These later models were used on almost all late-war German fighters, and its only real competition, the BMW III, was available only in very limited numbers. Compared to the Allied engines it faced, the D.III was generally outdated. Design and development The D.III was based on the same pattern as the earlier Mercedes D.II, suitably scaled up for higher power settings. Like most inlines of the era, it used a large aluminium crankcase as the main structural component, with separate cylinders made from steel bolted onto it. The technology for screwing a threaded cylinder of steel into an aluminium crankcase ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carburetor
A carburetor (also spelled carburettor or carburetter) is a device used by a gasoline internal combustion engine to control and mix air and fuel entering the engine. The primary method of adding fuel to the intake air is through the Venturi effect or Bernoulli's principle or with a Pitot tube in the main metering circuit, though various other components are also used to provide extra fuel or air in specific circumstances. Since the 1990s, carburetors have been largely replaced by fuel injection for cars and trucks, but carburetors are still used by some small engines (e.g. lawnmowers, generators, and concrete mixers) and motorcycles. In addition, they are still widely used on piston-engine–driven aircraft. Diesel engines have always used fuel injection instead of carburetors, as the compression-based combustion of diesel requires the greater precision and pressure of fuel injection. Etymology The term ''carburetor'' is derived from the verb ''carburet'', which means "to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hall-Scott
Hall-Scott Motor Car Company was an American manufacturing company based in Berkeley, California. It was among the most significant builders of water-cooled aircraft engines before World War I. History 1910–21 The company was founded in 1910 by Californians Elbert J. Hall and Bert C. Scott to manufacture engines for automobiles and later expanded the production of engines for trucks and airplanes as well as gasoline-powered rail cars and locomotives. Hall was a mechanic and engine builder and Scott, Stanford University-educated, was the business executive. They produced their first rail car in 1909, which they sold to the Yreka Railroad. In 1910, a factory was opened in Berkeley, California, with headquarters for a short time in San Francisco. The company built interurban electric railway cars for railroads such as the electrified Sacramento Northern, which ran trains from adjacent Oakland to Sacramento and Chico. The rail car business was slow, but some were sold as far a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Packard
Packard (formerly the Packard Motor Car Company) was an American luxury automobile company located in Detroit, Michigan. The first Packard automobiles were produced in 1899, and the last Packards were built in South Bend, Indiana, in 1958. One of the "Three Ps" – alongside Peerless Motor Company and Pierce-Arrow – the company was known for building high-quality luxury automobiles before World War II. Owning a Packard was considered prestigious, and surviving examples are often found in museums and automobile collections. Packard vehicles featured innovations, including the modern steering wheel, air-conditioning in a passenger car, and one of the first production 12-cylinder engines, adapted from developing the Liberty L-12 engine used during World War I to power warplanes. During World War II, Packard produced 55,523 units of the two-stage/two-speed supercharger equipped Merlin V-12s engines under contract with Rolls-Royce. Packard also made the versions of the Li ...

Rocker Cover
A rocker cover, (UK), or valve cover (elsewhere) is a cover that encloses the rocker arm in an internal combustion engine, bolting with a gasket seal to the engine head. Engines with more than one head (such as a V8) will have multiple rocker covers. On engines without rocker arms, such as some overhead cam and most dual overhead cam types, they are known as rocker boxes in the United Kingdom. On modern engines without rocker arms they are internationally known as "valve cover" but are sometimes referred to as a "cam cover" or "timing cover" if they also cover the timing gear(s) and belt or chain. Very large multi-cylinder engines, such as those used in a ship or in aviation, may have one rocker cover for each cylinder, to make removal and installation more manageable. History Rocker covers did not exist in early engines, which had exposed intake and exhaust valves (for ease of lubrication). With the advance of central lubrication rocker covers were added to keep the oil in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Benzene
Benzene is an Organic compound, organic chemical compound with the Chemical formula#Molecular formula, molecular formula C6H6. The benzene molecule is composed of six carbon atoms joined in a planar hexagonal Ring (chemistry), ring with one hydrogen atom attached to each. Because it contains only carbon and hydrogen atoms, benzene is classed as a hydrocarbon. Benzene is a natural constituent of petroleum and is one of the elementary petrochemicals. Due to the cyclic continuous pi bonds between the carbon atoms, benzene is classed as an aromatic hydrocarbon. Benzene is a colorless and highly Combustibility and flammability, flammable liquid with a sweet smell, and is partially responsible for the aroma of gasoline. It is used primarily as a Precursor (chemistry), precursor to the manufacture of chemicals with more complex structures, such as ethylbenzene and cumene, of which billions of kilograms are produced annually. Although benzene is a major Chemical industry, industrial che ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fokker D
Fokker (; ) was a Dutch aircraft manufacturer that operated from 1912 to 1996. The company was founded by the Dutch aviator Anthony Fokker and became famous during World War I for its fighter aircraft. During its most successful period in the 1920s and 1930s, Fokker dominated the civil aviation market. The company's fortunes declined over the course of the late 20th century; it declared bankruptcy in 1996, and its operations were sold to competitors. History Fokker in Germany At age 20, while studying in Germany, Anthony Fokker built his initial aircraft, the ''Spin'' (Spider)—the first Dutch-built plane to fly in his home country. Taking advantage of better opportunities in Germany, he moved to Berlin, where in 1912, he founded his first company, Fokker Aeroplanbau, later moving to the Görries suburb just southwest of Schwerin (at ), where the current company was founded, as Fokker Aviatik GmbH, on 12 February 1912.

Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the imperial horsepower as in "hp" or "bhp" which is about , and the metric horsepower as in "cv" or "PS" which is approximately . The electric horsepower "hpE" is exactly , while the boiler horsepower is 9809.5 or 9811 watts, depending on the exact year. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other power-generating machinery such as piston engines, turbines, and electric motors. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 201 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
