Robert Huber (engineer)
Robert Huber (7 July 1901 - 7 April 1995) was born in Freienstein, Switzerland. He attended a primary school in Freienstein from 1908 to 1914 and a secondary school in Freienstein from 1914 to 1916. From 1916 to 1920 he attended a high school in Zurich. From 1920 to 1924 he studied at the Swiss Federal Institute of Technology (now ETH Zurich) under Professor Aurel Stodola. Career In 1924, Huber became Technical Director of the Raúl Pateras Pescara, Bureau Technique Pescara where he supervised the design of nearly 30 different sizes and types of free-piston engine and acquired the nickname "Mr Free Piston". The first was the AC-2, running on petrol (gasoline). The second was the AC-3, which was similar but ran on diesel fuel. Eighteen types of free-piston engine were built and tested. In 1932, Huber read a book by Yury Lomonosov, Professor Lomonosov about diesel locomotives. He also heard of a proposal by Petro Shelest for turbines driven by compressed air.

Diesel Locomotive
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. Early internal combustion locomotives and railcars used kerosene and gasoline as their fuel. Rudolf Diesel patented his first compression-ignition engine in 1898, and steady improvements to the design of diesel engines reduced their physical size and improved their power-to-weight ratios to a point where one could be mounted in a locomotive. Internal combustion engines only operate efficiently within a limited power band, and while low power gasoline engines could be coupled to mechanical transmissions, the more powerful diesel engines required the development of new forms of transmission. This is because clutches would need to be very large at these power levels and would not fit in a standard -wide locomotive frame, or wear too quic ...

Common Rail
Common rail direct fuel injection is a direct fuel injection system built around a high-pressure (over ) fuel rail feeding solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors (or pump nozzles). High-pressure injection delivers power and fuel consumption benefits over earlier lower pressure fuel injection, by injecting fuel as a larger number of smaller droplets, giving a much higher ratio of surface area to volume. This provides improved vaporization from the surface of the fuel droplets, and so more efficient combining of atmospheric oxygen with vaporized fuel delivering more complete combustion. Common rail injection is widely used in diesel engines. It is also the basis of gasoline direct injection systems used on petrol engines. History Vickers pioneered the use of common rail injection in submarine engines. Vickers engines with the common rail fuel system were first used in 1916 in the G-class submarines. It used four plunger pumps to deliver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alternator
An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature.Gordon R. Selmon, ''Magnetoelectric Devices'', John Wiley and Sons, 1966 no ISBN pp. 391-393 Occasionally, a linear alternator or a rotating armature with a stationary magnetic field is used. In principle, any AC electrical generator can be called an alternator, but usually the term refers to small rotating machines driven by automotive and other internal combustion engines. An alternator that uses a permanent magnet for its magnetic field is called a magneto. Alternators in power stations driven by steam turbines are called turbo-alternators. Large 50 or 60 Hz three-phase alternators in power plants generate most of the world's electric power, which is distributed by electric power grids. History Alternating current generating ...

Free-piston Gas Turbine
A free-piston engine is a linear, 'crankless' internal combustion engine, in which the piston motion is not controlled by a crankshaft but determined by the interaction of forces from the combustion chamber gases, a rebound device (e.g., a piston in a closed cylinder) and a load device (e.g. a gas compressor or a linear alternator). The purpose of all such piston engines is to generate power. In the free-piston engine, this power is not delivered to a crankshaft but is instead extracted through either exhaust gas pressure driving a turbine, through driving a linear load such as an air compressor for pneumatic power, or by incorporating a linear alternator directly into the pistons to produce electrical power. The basic configuration of free-piston engines is commonly known as single piston, dual piston or opposed pistons, referring to the number of combustion cylinders. The free-piston engine is usually restricted to the two-stroke operating principle, since a power stroke is requi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbine
A turbine ( or ) (from the Greek , ''tyrbē'', or Latin ''turbo'', meaning vortex) is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced by a turbine can be used for generating electrical power when combined with a generator.Munson, Bruce Roy, T. H. Okiishi, and Wade W. Huebsch. "Turbomachines." Fundamentals of Fluid Mechanics. 6th ed. Hoboken, NJ: J. Wiley & Sons, 2009. Print. A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor. Early turbine examples are windmills and waterwheels. Gas, steam, and water turbines have a casing around the blades that contains and controls the working fluid. Credit for invention of the steam turbine is given both to Anglo-Irish engineer Sir Charles Parsons (1854–1931) for invention of the reaction turbine, and to ...

Petro Shelest
Petro Yukhymovych Shelestrussian: Пётр Ефи́мович Ше́лест, translit=Pyotr Yefimovich Shelest (14 February 190822 January 1996) was a Ukrainian Soviet politician. First Secretary of the Communist Party of the Ukrainian Soviet Socialist Republic, a member of the Politburo of the Communist Party of the Soviet Union and a deputy of the Supreme Soviet of the Ukrainian SSR. Early career Petro Shelest was born in a Ukrainian peasant family in a village near Kharkiv in 1908. He studied engineering in Kharkiv, and held industrial jobs between 193 and 1936. In 1928 he joined the Communist Party of the Soviet Union (CPSU) and in 1935 graduated from Mariupol Metallurgical Institute. He served in the Red Army from 1936 to 1937, but transferred to working for the Communist Party in 1937, as thousands of its members were caught up in the Great Purge. Between 1943 and 1954, Shelest was a chief manager of several large factories in Leningrad and Kyiv. From 1954 to 1963, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yury Lomonosov
Yury Vladimirovich Lomonosov (russian: Юрий Владимирович Ломоносов; 24 April 1876 – 19 November 1952) was a Russian railway engineer and a leading figure in the development of Russian Railways in the early 20th century. He was best known for design and construction of the world's first operationally successful mainline diesel locomotive, the E el-2. This was completed in 1924 and went into service in 1925.Heywood, p.209 In the late 1920s, Lomonosov immigrated to Europe and later became a British citizen. Early years Lomonosov was born in 1876 in Gzhatsk (now Gagarin), a town in Smolensk Oblast of Russia. His father Vladimir Grigorievich Lomonosov was a former cavalry officer who worked as a judge since 1870. His mother Maria Fedorovna Lomonosova (née Pegelau) was a housewife known for establishing a public library.Norman E"Тепловоз профессора Ю.В.Ломоносова – первенец советского и мирового ...

Diesel Fuel
Diesel fuel , also called diesel oil, is any liquid fuel specifically designed for use in a diesel engine, a type of internal combustion engine in which fuel ignition takes place without a spark as a result of compression of the inlet air and then injection of fuel. Therefore, diesel fuel needs good compression ignition characteristics. The most common type of diesel fuel is a specific fractional distillate of petroleum fuel oil, but alternatives that are not derived from petroleum, such as biodiesel, biomass to liquid (BTL) or gas to liquid (GTL) diesel are increasingly being developed and adopted. To distinguish these types, petroleum-derived diesel is sometimes called petrodiesel in some academic circles. In many countries, diesel fuel is standardised. For example, in the European Union, the standard for diesel fuel is EN 590. Diesel fuel has many colloquial names; most commonly, it is simply referred to as ''diesel''. In the United Kingdom, diesel fuel for on-road use is c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gasoline
Gasoline (; ) or petrol (; ) (see ) is a transparent, petroleum-derived flammable liquid that is used primarily as a fuel in most spark-ignited internal combustion engines (also known as petrol engines). It consists mostly of organic compounds obtained by the fractional distillation of petroleum, enhanced with a variety of additives. On average, U.S. refineries produce, from a barrel of crude oil, about 19 to 20 gallons of gasoline; 11 to 13 gallons of distillate fuel (most of which is sold as diesel fuel); and 3 to 4 gallons of jet fuel. The product ratio depends on the processing in an oil refinery and the crude oil assay. A barrel of oil is defined as holding 42 US gallons, which is about 159 liters or 35 imperial gallons. The characteristic of a particular gasoline blend to resist igniting too early (which causes knocking and reduces efficiency in reciprocating engines) is measured by its octane rating, which is produced in several grades.
