British Rail Class 170
The British Rail Class 170 ''Turbostar'' is a British diesel-hydraulic multiple unit passenger train designed and built by Adtranz, and later by Bombardier Transportation, at Derby Litchurch Lane Works. The Class 170 was derived from the and DMUs, known as the ''Networker Turbos'', of the 1990s. The first units were introduced to service in 1999, shortly after the privatisation of British Rail; they have been commonly used to operate regional as well as long-distance services, and to a lesser extent suburban services. A total of 139 units were built, but some were later converted to and units. These trains are currently in use with CrossCountry, East Midlands Railway, Northern Trains and ScotRail. Design The Class 170 diesel multiple unit (DMU) is a development of the design used in the and DMUs known as the ''Networker Turbos'' and built by British Rail Engineering Limited and later ABB Transportation before that company became part of Bombardier.

Northern Trains
Northern Trains, Trade name, trading as Northern, is a British train operating company that operates Commuter rail, commuter and Inter-city rail, medium-distance intercity services in the North of England. It is owned by DfT Operator for the Department for Transport (DfT), after the previous operator Arriva Rail North had its franchise terminated at the end of February 2020. The company commenced operating the Northern franchise on 1 March 2020, taking over from Arriva Rail North. The prior operator had its franchise terminated early by the DfT in January 2020 amid widespread dissatisfaction over its performance, particularly in respect of poorly implemented timetable changes. The DfT had opted to hand the operation of the franchise over to the operator of last resort. At the commencement of operations, Northern publicly stated that its immediate aims were to improve service reliability and to proceed with the introduction of new rolling stock. For the latter, both the British Ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Modern Railways
''Modern Railways'' is a monthly British magazine covering the rail transport industry, which was published by Ian Allan until March 2012 and Key Publishing since then. It has been published since 1962. The magazine was based originally in Shepperton, Surrey, and Tunbridge Wells subsequently.

Hydrokinetic Transmission
A torque converter is a device, usually implemented as a type of fluid coupling, that transfers rotating power from a prime mover, like an internal combustion engine, to a rotating driven load. In a vehicle with an automatic transmission, the torque converter connects the prime mover to the automatic gear train, which then drives the load. It is thus usually located between the engine's flexplate and the transmission. The equivalent device in a manual transmission is the mechanical clutch. A torque converter serves to increase transmitted torque when the output rotational speed is low. In the fluid coupling embodiment, it uses a fluid, driven by the vanes of an input impeller, and directed through the vanes of a fixed stator, to drive an output turbine in such a manner that torque on the output is increased when the output shaft is rotating more slowly than the input shaft, thus providing the equivalent of an adaptive reduction gear. This is a feature beyond what a simple fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voith
The Voith Group is a global technology company. With its broad portfolio of systems, products, services and digital applications, Voith trades in the markets of energy, paper, raw materials and transport. Founded in 1867, Voith today has around 22,000 employees, sales of € 5.2 billion and locations in over 60 countries worldwide and thus is one of the larger family-owned companies in Europe. Company history Years of foundation In 1825, Johann Matthäus Voith took over his father's locksmith's workshop in Heidenheim with five employees, mainly carrying out repairs to water wheels and paper mills. Around 1830 in Heidenheim, there were about 600 people working in 15 factories, mostly textile factories that had been established by wealthy merchants and publishers. The necessary maintenance and repair of the expensive machinery offered a source of income to several workshops, particularly the locksmiths and metalworkers in what was still a small town at the time. In 1830, Joha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbo-diesel
The term turbo-diesel, also written as turbodiesel and turbo diesel, refers to any diesel engine equipped with a turbocharger. As with other engine types, turbocharging a diesel engine can significantly increase its efficiency and power output, especially when used in combination with an intercooler. Turbocharging of diesel engines began in the 1920s with large marine and stationary engines. Trucks became available with turbo-diesel engines in the mid-1950s, followed by passenger cars in the late 1970s. Since the 1990s, the compression ratio of turbo-diesel engines has been dropping. Principle Diesel engines are typically well suited to turbocharging due to two factors: * A "lean" air–fuel ratio, caused when the turbocharger supplies excess air into the engine, is not a problem for diesel engines, because the torque control is dependent on the mass of fuel that is injected into the combustion chamber (i.e. air-fuel ratio), rather than the quantity of the air-fuel mixture. ...

Four-stroke Engine
A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: #Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing a partial vacuum (negative pressure) in the cylinder through its downward motion. #Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves are closed during this stage. #Combustion: Also known as power or ignition. This is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Straight Engine
The straight engine (also called inline engine) is a configuration of multi-cylinder piston engine where all of the cylinders are arranged in a single row, rather than radially or in two or more cylinder banks. Design A straight engine is easier to build than an equivalent flat engine or V engine, as it uses one cylinder head rather than two. Inline engines are also narrower than flat engines or V engines; however, they are longer and can be taller. The engine balance characteristics of a straight engine depend on the number of cylinders and the firing interval. Slant engines and horizontally-mounted engines When a straight engine is mounted at an angle from the vertical it is called a ''slant engine''. Notable slant engines include the 1959-2000 Chrysler Slant-6 engine, 1961-63 Pontiac Trophy 4 engine and the 1968-1981 Triumph Slant-4 engine. Some buses and diesel multiple unit trains take this concept further by mounting the engines horizontally (i.e. with a slant ...

MTU Friedrichshafen
MTU Friedrichshafen GmbH, trading as MTU Solutions (stylised as mtu Solutions) is a German manufacturer of commercial internal combustion engines founded by Wilhelm Maybach and his son Karl Maybach in 1909. Wilhelm Maybach was the technical director of Daimler-Motoren-Gesellschaft (DMG), a predecessor company of the German multinational automotive corporation Daimler AG, until he left in 1907. On 23 March 1909, he founded the new company, Luftfahrzeug-Motorenbau GmbH (Aircraft Engine Manufacturing Corp), with his son Karl Maybach as director. A few years later the company was renamed to Maybach-Motorenbau GmbH (Maybach Engine Manufacturing Corp), which originally developed and manufactured diesel and petrol engines for Zeppelins, and then railcars. The Maybach Mb.IVa was used in aircraft and airships of World War I. The company first built an experimental car in 1919, with the first production model introduced two years later at the Berlin Motor Show. Between 1921 and 1940, t ...

Steel
Steel is an alloy of iron and carbon that demonstrates improved mechanical properties compared to the pure form of iron. Due to steel's high Young's modulus, elastic modulus, Yield (engineering), yield strength, Fracture, fracture strength and low raw material cost, steel is one of the most commonly manufactured materials in the world. Steel is used in structures (as concrete Rebar, reinforcing rods), in Bridge, bridges, infrastructure, Tool, tools, Ship, ships, Train, trains, Car, cars, Bicycle, bicycles, Machine, machines, Home appliance, electrical appliances, furniture, and Weapon, weapons. Iron is always the main element in steel, but other elements are used to produce various grades of steel demonstrating altered material, mechanical, and microstructural properties. Stainless steels, for example, typically contain 18% chromium and exhibit improved corrosion and Redox, oxidation resistance versus its carbon steel counterpart. Under atmospheric pressures, steels generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminium
Aluminium (or aluminum in North American English) is a chemical element; it has chemical symbol, symbol Al and atomic number 13. It has a density lower than that of other common metals, about one-third that of steel. Aluminium has a great affinity towards oxygen, passivation (chemistry), forming a protective layer of aluminium oxide, oxide on the surface when exposed to air. It visually resembles silver, both in its color and in its great ability to reflect light. It is soft, magnetism, nonmagnetic, and ductility, ductile. It has one stable isotope, 27Al, which is highly abundant, making aluminium the abundance of the chemical elements, 12th-most abundant element in the universe. The radioactive decay, radioactivity of aluminium-26, 26Al leads to it being used in radiometric dating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ ...

Welding
Welding is a fabrication (metal), fabrication process that joins materials, usually metals or thermoplastics, primarily by using high temperature to melting, melt the parts together and allow them to cool, causing Fusion welding, fusion. Common alternative methods include solvent welding (of thermoplastics) using chemicals to melt materials being bonded without heat, and #Solid-state welding, solid-state welding processes which bond without melting, such as pressure, cold welding, and diffusion bonding. Metal welding is distinct from lower temperature bonding techniques such as brazing and soldering, which do not melt the base metal (parent metal) and instead require flowing a filler metal to solidify their bonds. In addition to melting the base metal in welding, a filler material is typically added to the joint to form a pool of molten material (the weld pool) that cools to form a joint that can be stronger than the base material. Welding also requires a form of shield to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
