Herbert Akroyd Stuart
Herbert Akroyd-Stuart (28 January 1864 – 19 February 1927) was an English inventor who is noted for his invention of the hot bulb engine, or heavy oil engine. Life Akroyd-Stuart was born in Halifax, Yorkshire, but lived in Australia for a period in his early years. He was educated at Newbury Grammar School (now St. Bartholomew's School) and Finsbury Technical College in London. He was the son of Charles Stuart, founder of the Bletchley Iron and Tinplate Works, joining his father in the business in 1887. Oil engines In 1885, Akroyd Stuart accidentally spilt paraffin oil (kerosene) into a pot of molten tin. The paraffin oil vaporised and caught fire when in contact with a paraffin lamp. This gave him an idea to pursue the possibility of using paraffin oil (very similar to modern-day diesel) for an engine, which unlike petrol proved difficult to vaporise in a carburettor because its volatility is insufficient. His first prototype engines were built in 1886. In 1890, in coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuel Injection
Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of an injector. This article focuses on fuel injection in reciprocating piston and Wankel rotary engines. All compression-ignition engines (e.g. diesel engines), and many spark-ignition engines (i.e. petrol engines, such as Otto or Wankel), use fuel injection of one kind or another. Mass-produced diesel engines for passenger cars (such as the Mercedes-Benz OM 138) became available in the late 1930s and early 1940s, being the first fuel-injected engines for passenger car use. In passenger car petrol engines, fuel injection was introduced in the early 1950s and gradually gained prevalence until it had largely replaced carburettors by the early 1990s. The primary difference between carburetion and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while a carburettor relies on suction created by intake ai ...

Scotland On Sunday
''Scotland on Sunday'' is a Scottish Sunday newspaper, published in Edinburgh by JPIMedia and consequently assuming the role of Sunday sister to its daily stablemate ''The Scotsman''. It was originally printed in broadsheet format but in 2013 was relaunched as a tabloid. Since this latest relaunch it comprises three parts, the newspaper itself which includes the original "Insight" section, a sports section and ''Spectrum'' magazine which incorporates ''At Home'', originally a separate magazine. It backed a 'No' vote in the referendum on Scottish independence. History ''Scotland on Sunday'' was launched on 7 August 1988 and was priced at 40p. Ultimate ownership of ''Scotland on Sunday'' has changed several times since launch. The Scotsman Publications Limited, which also produces ''The Scotsman'', ''Edinburgh Evening News'' and the ''Herald & Post'' series of free newspapers in Edinburgh, Fife, West Lothian and Perth, was bought by the Canadian millionaire Roy Thomson in 1 ...

Theory And Construction Of A Rational Heat Motor
''Theory and Construction of a Rational Heat Motor'' (german: Theorie und Konstruktion eines rationellen Wärmemotors zum Ersatz der Dampfmaschine und der heute bekannten Verbrennungsmotoren; English: ''Theory and construction of a rational heat motor with the purpose of replacing the steam engine and the internal combustion engines known today'') is an essay written by German engineer Rudolf Diesel. It was composed in 1892, and first published by Springer in 1893. A translation into English followed in 1894. One thousand copies of the German first edition were printed. In this essay, Rudolf Diesel describes his idea of an internal combustion engine based on the Carnot cycle, transforming heat energy into kinetic energy using high pressure, with a thermal efficiency of up to 73%, outperforming any steam engine of the time. Diesel sent copies of his essay to famous German engineers and university professors for spreading and promoting his idea. He received plenty of negative fee ...

Petroleum Oil
Mineral oil is any of various colorless, odorless, light mixtures of higher alkanes from a mineral source, particularly a distillate of petroleum, as distinct from usually edible vegetable oils. The name 'mineral oil' by itself is imprecise, having been used for many specific oils over the past few centuries. Other names, similarly imprecise, include 'white oil', 'paraffin oil', 'Liquid paraffin (medicinal), liquid paraffin' (a highly refined medical grade), (Latin), and 'liquid petroleum'. Most often, mineral oil is a liquid by-product of Oil refinery, refining crude oil to make gasoline and other petroleum products. This type of mineral oil is a Transparency and translucency, transparent, colorless oil, composed mainly of alkanes and cycloalkanes, related to petroleum jelly. It has a density of around . Nomenclature Some of the imprecision in the definition of the names used for mineral oil (such as 'white oil') reflects usage by consumers and merchants who did not know, a ...

Vapor-compression Refrigeration
Vapour-compression refrigeration or vapor-compression refrigeration system (VCRS), in which the refrigerant undergoes phase changes, is one of the many refrigeration cycles and is the most widely used method for air conditioning of buildings and automobiles. It is also used in domestic and commercial refrigerators, large-scale warehouses for chilled or frozen storage of foods and meats, refrigerated trucks and railroad cars, and a host of other commercial and industrial services. Oil refineries, petrochemical and chemical processing plants, and natural gas processing plants are among the many types of industrial plants that often utilize large vapor-compression refrigeration systems. Cascade refrigeration systems may also be implemented using two compressors. Refrigeration may be defined as lowering the temperature of an enclosed space by removing heat from that space and transferring it elsewhere. A device that performs this function may also be called an air conditioner, refrige ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Narrowboat
A narrowboat is a particular type of canal boat, built to fit the narrow locks of the United Kingdom. The UK's canal system provided a nationwide transport network during the Industrial Revolution, but with the advent of the railways, commercial canal traffic gradually diminished and the last regular long-distance transportation of goods by canal had virtually disappeared by 1970. However, some commercial traffic continued. From the 1970s onward narrowboats were gradually being converted into permanent residences or as holiday lettings. Currently, about 8580 narrowboats are registered as 'permanent homes' on Britain's waterway system and represent a growing alternative community living on semi-permanent moorings or continuously cruising. For any boat to enter a narrow lock, it must be under wide, so most narrowboats are nominally wide. A narrowboat's maximum length is generally , as anything longer will be unable to navigate much of the British canal network, because the n ...
