A locomotive or engine is a rail transport vehicle that provides the motive power for a train. If a locomotive is capable of carrying a payload, it is usually rather referred to as a multiple unit, motor coach, railcar or power car; the use of these self-propelled vehicles is increasingly common for passenger trains, but rare for freight.
An auxiliary power unit (APU) is a device on a vehicle that provides energy for functions other than propulsion. They are commonly found on large aircraft and naval ships as well as some large land vehicles. Aircraft APUs generally produce 115 V alternating current (AC) at 400 Hz, to run the electrical systems of the aircraft; others can produce 28 V direct current (DC). APUs can provide power through single- or three-phase systems.
A diesel locomotive is a type of railway locomotive in which the prime mover is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels.
The English Electric Company Limited (EE) was a British industrial manufacturer formed after the armistice of World War I by amalgamating five businesses which, during the war, had been making munitions, armaments and aeroplanes.
Liquefied natural gas (LNG) is natural gas (predominantly methane, CH4, with some mixture of ethane, C2H6) that has been cooled down to liquid form for ease and safety of non-pressurized storage or transport. It takes up about 1/600th the volume of natural gas in the gaseous state (at standard conditions for temperature and pressure). It is odorless, colorless, non-toxic and non-corrosive. Hazards include flammability after vaporization into a gaseous state, freezing and asphyxia. The liquefaction process involves removal of certain components, such as dust, acid gases, helium, water, and heavy hydrocarbons, which could cause difficulty downstream. The natural gas is then condensed into a liquid at close to atmospheric pressure by cooling it to approximately −162 °C (−260 °F); maximum transport pressure is set at around 25 kPa (4 psi).
A natural gas vehicle (NGV) is also an alternative fuel vehicle that uses compressed natural gas (CNG) or liquefied natural gas (LNG). Natural gas vehicles should not be confused with autogas vehicles powered by liquefied petroleum gas (LPG), mainly propane, which is a fuel with a fundamentally different composition.
MTU Friedrichshafen GmbH is a 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, with his son Karl Maybach as director. A few years later the company was renamed to Maybach-Motorenbau GmbH, 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 Ganz Works or Ganz was a group of companies operating between 1845 and 1949 in Budapest, Hungary. It was named after Ábrahám Ganz, the founder and the manager of the company. It is probably best known for the manufacture of tramcars, but was also a pioneer in the application of three-phase alternating current to electric railways. Ganz also made ships, bridge steel structures and high-voltage equipment. In the early 20th century the company experienced its heyday, it became the third largest industrial enterprise in Kingdom of Hungary after the Manfréd Weiss Steel and Metal Works and the MÁVAG company. Since 1989, various parts of Ganz have been taken over by other companies.
Progress Rail Locomotives, doing business as Electro-Motive Diesel (EMD) is an American manufacturer of diesel-electric locomotives, locomotive products and diesel engines for the rail industry. The company is owned by Caterpillar through its subsidiary Progress Rail Services.
In rail transport, head-end power (HEP), also known as electric train supply (ETS), is the electrical power distribution system on a passenger train. The power source, usually a locomotive at the front or 'head' of a train, provides the electricity used for heating, lighting, electrical and other 'hotel' needs. The maritime equivalent is hotel electric power. A successful attempt by the London, Brighton and South Coast Railway in October 1881 to light the passenger cars between London and Brighton heralded the beginning of using electricity to light trains in the world.
A diesel generator (DG) is the combination of a diesel engine with an electric generator to generate electrical energy. This is a specific case of engine-generator. A diesel compression-ignition engine is usually designed to run on diesel fuel, but some types are adapted for other liquid fuels or natural gas.
Marine propulsion is the mechanism or system used to generate thrust to move a ship or boat across water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or engine turning a propeller, or less frequently, in pump-jets, an impeller. Marine engineering is the discipline concerned with the engineering design process of marine propulsion systems.
Generac Holdings Inc., commonly referred to as Generac, is a Fortune 1000 American manufacturer of backup power generation products for residential, light commercial and industrial markets. Generac's power systems range in output from 800 watts to 9 megawatts, and are available through independent dealers, retailers and wholesalers. Generac is headquartered in Waukesha, Wisconsin, and has manufacturing facilities in Berlin, Oshkosh, Jefferson, Eagle, and Whitewater; all in Wisconsin.
Natural gas was the Canada's third largest source of energy production in 2018, representing 22.3% of all energy produced from fuels in the country. By contrast, the share of fuel-based energy production from natural gas in 2013 was 17.0%, indicating a growth rate of approximately 1.06% per year.
Q-Max is a type of ship, specifically a membrane type liquefied natural gas carrier. In the name Q-Max, "Q" stands for Qatar and "Max" for the maximum size of ship able to dock at the LNG terminals in Qatar. Ships of this type are the largest LNG carriers in the world.
The Paxman Ventura is a diesel engine for railway locomotives, built by Davey, Paxman & Co.
Iran Heavy Diesel Manufacturing Company(DESA), is an Iranian company which is a manufacturer of heavy diesel engines from 200 to 3500 kW for railway, marine and power generation purposes.
Dhekelia Power Station is one of three power plants belonging to the Electricity Authority of Cyprus. It is located approximately 15 kilometres (9.3 mi) east of the city of Larnaca and it has a capacity of 460 MW.
Perkins Engines Company Limited, a subsidiary of Caterpillar Inc, is primarily a diesel engine manufacturer for several markets including agricultural, construction, material handling, power generation and industrial. It was established in Peterborough, England, in 1932. Over the years Perkins has expanded its engine ranges and produces thousands of different engine specifications including diesel and petrol engines.
On marine vessels the Power Management System PMS is in charge of controlling the electrical system. Its task is to make sure that the electrical system is safe and efficient. If the power consumption is larger than the power production capacity, load shedding is used to avoid blackout. Other features could be to automatic start and stop consumers as the load varies.
