Diesel–electric Powertrain
A diesel–electric transmission, or diesel–electric powertrain, is a transmission (mechanics), transmission system powered by diesel engines for vehicles in #Road and other land vehicles, road, #Railway locomotives, rail, and #Ships, marine transport. Diesel–electric transmission is similar to petrol–electric transmission, which is powered by petrol engines. Diesel–electric transmission is used on railways by Diesel locomotive#Diesel–electric, diesel–electric locomotives and Diesel multiple unit#Diesel–electric, diesel–electric multiple units, as electric motors are able to supply full torque from 0 revolutions per minute, RPM. Diesel–electric systems are also used in marine transport, including submarines, and on some other land vehicles. Description The defining characteristic of diesel–electric transmission is that it avoids the need for a gearbox, by converting the mechanical force of the diesel engine into electrical energy (through an alternator), and ...

Electrical Energy
Electrical energy is the energy transferred as electric charges move between points with different electric potential, that is, as they move across a voltage, potential difference. As electric potential is lost or gained, work is done changing the energy of some system. The amount of work in Joule, joules is given by the product of the charge that has moved, in Coulomb, coulombs, and the potential difference that has been crossed, in Volt, volts. Electrical energy is usually sold by the kilowatt hour (1 kW·h = 3.6 MJ) which is the product of the power in kilowatts multiplied by running time in hours. Electric utilities measure energy using an electricity meter, which keeps a running total of the electrical energy delivered to a customer. Electric heating is an example of converting electrical energy into thermal energy. The simplest and most common type of electric heater uses electrical resistance to convert the energy. There are other ways to use electrical energy. Electri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Branobel
The Petroleum Production Company Nobel Brothers, Limited, or Branobel (short for братьев Нобель "brat'yev Nobel" – "Nobel Brothers" in Russian), was an oil company set up by Ludvig Nobel and Baron Peter von Bilderling. It operated mainly in Baku, Azerbaijan, but also in Cheleken, Turkmenistan. Originally established by Robert Nobel (who contributed 25,000 rubles) and the investments of barons Peter von Bilderling (300,000 rubles) and Standertskjöld (150,000 rubles) as a distillery in 1876, it became, during the late-19th century, one of the largest oil-companies in the world. History The Nobel Brothers Petroleum Company was an oil-producing company that had its origins in a distillery, founded by Robert and Ludvig Nobel in Baku in 1876, which, in 1879, turned into a shareholding company headquartered in St. Petersburg.

Vandal (tanker)
''Vandal'' was a river tanker designed by Karl Hagelin and Johny Johnson for Branobel. Russian ''Vandal'' and French '' Petite-Pierre'', launched in 1903, were the world's first diesel-powered ships (sources disagree over which of the two, ''Vandal'' or ''Petite-Pierre'', was ''the'' first). ''Vandal'' was the first equipped with fully functional diesel-electric transmission. In the 1890s oil industry searched for an economical oil-burning engine, and the solution was found by German engineer Rudolph Diesel.Tolf, p. 168. Diesel marketed his technology to oil barons around the world;His first licensees included Vickers, Burmeister and Vain and Adolphus Busch. in February 1898 he granted exclusive licenses to build his engines in Sweden and Russia to Emanuel Nobel of the Nobel family.Tolf, p. 169. The Russian licence cost Nobel 800,000 marks in cash and stock of the newly founded Russian Diesel Company. The Saint Petersburg engine plant was a quick success; it started with di ...

Low-emission Zone
A low-emission zone (LEZ) is a defined area where access by some polluting vehicles is restricted or deterred with the aim of improving air quality. This may favour vehicles such as bicycles, micromobility vehicles, (certain) alternative fuel vehicles, hybrid electric vehicles, plug-in hybrids, and zero-emission vehicles such as all-electric vehicles. A ultra-low-emission zone (ULEZ) is a zone with a stricter emissions requirement than LEZ. A zero-emission zone (ZEZ) is a LEZ where only zero-emissions vehicles (ZEVs) are allowed. In such areas, all internal combustion engine vehicles are banned; this includes any plug-in hybrid vehicles which cannot run zero-emission. Only battery electric vehicles and hydrogen vehicles are allowed in a ZEZ, along with walking and cycling and fully electric public transport vehicles, e.g. trams, electric buses etc. Workings In many LEZs, vehicles that do not meet the emission standards set by the LEZ are not barred from entry into the LE ...

Clutch
A clutch is a mechanical device that allows an output shaft to be disconnected from a rotating input shaft. The clutch's input shaft is typically attached to a motor, while the clutch's output shaft is connected to the mechanism that does the work. In a motor vehicle, the clutch acts as a mechanical linkage between the engine and transmission. By disengaging the clutch, the engine speed (RPM) is no longer determined by the speed of the driven wheels. Another example of clutch usage is in electric drills. The clutch's input shaft is driven by a motor and the output shaft is connected to the drill bit (via several intermediate components). The clutch allows the drill bit to either spin at the same speed as the motor (clutch engaged), spin at a lower speed than the motor (clutch slipping) or remain stationary while the motor is spinning (clutch disengaged). Types Dry clutch A ''dry clutch'' uses dry friction to transfer power from the input shaft to the output shaft, f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas Turbine
A gas turbine or gas turbine engine is a type of Internal combustion engine#Continuous combustion, continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the direction of flow: * a rotating gas compressor * a combustor * a compressor-driving turbine. Additional components have to be added to the gas generator to suit its application. Common to all is an air inlet but with different configurations to suit the requirements of marine use, land use or flight at speeds varying from stationary to supersonic. A propelling nozzle is added to produce thrust for flight. An extra turbine is added to drive a propeller (turboprop) or ducted fan (turbofan) to reduce fuel consumption (by increasing propulsive efficiency) at subsonic flight speeds. An extra turbine is also required to drive a helicopter rotor or land-vehicle transmission (turboshaft), marine propeller or electric ...

Turbine–electric Powertrain
A turbine–electric transmission or turbine–electric powertrain system includes a turboshaft gas turbine connected to an electrical generator, creating electricity that powers electric motor, electric traction motors. No clutch is required. Turbine–electric transmissions are used to drive both gas turbine locomotives (rarely) and warships. Locomotive applications A handful of experimental locomotives from the 1930s and 1940s used gas turbines as prime mover (locomotive), prime movers. These turbines were based on stationary practice, with single large reverse-flow combustors, heat exchangers and using low-cost heavy oil bunker fuel. In the 1960s the idea re-emerged, using developments in light weight engines developed for helicopters and using lighter kerosene fuels. As these turbines were compact and lightweight, the vehicles were produced as railcars rather than separate locomotives. Naval applications Turboelectric powertrains are a subset of what is referred to in m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid Electric Vehicle
A hybrid electric vehicle (HEV) is a type of hybrid vehicle that couples a conventional internal combustion engine (ICE) with one or more electric engines into a hybrid vehicle drivetrain, combined propulsion system. The presence of the electric powertrain, which has inherently better energy conversion efficiency, is intended to achieve either better fuel economy in automobiles, fuel economy or better acceleration performance than a conventional vehicle. There is a variety of HEV types and the degree to which each functions as an electric vehicle (EV) also varies. The most common form of HEV is hybrid electric passenger cars, although hybrid electric trucks (pickup truck, pickups, tow trucks and tractors), buses, motorboats, and aircraft also exist. Modern HEVs use energy recovery technologies such as motor–generator units. and regenerative braking to recycle the vehicle's kinetic energy to electric energy via an alternator (automotive), alternator, which is energy storage, st ...
