Petrol-paraffin Engine
A petrol-paraffin engine, TVO engine (United Kingdom) or gasoline-kerosene engine (North America) is an old-fashioned type of dual-fuel internal combustion engine with spark-ignition, designed to start on petrol (gasoline) and then to switch to run on paraffin (kerosene) once the engine is warm. The grade of paraffin used is known as tractor vaporising oil in the UK. Advantages Petrol-paraffin engines carry certain advantages, though time and technology has rendered them mostly outmoded. # Paraffin, historically, was cheaper and/or more readily available in certain markets, especially post-WWII Britain, a major market for the fuel. # Being less flammable, paraffin is safer to store. # Being less volatile, paraffin is less likely to go " stale" in the tank. The cost and availability advantages, however, have become illusory with time; paraffin, once widely available as a cheap fuel, has become rarer and more expensive, particularly in developed countries. Also, while some olde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Hesselman Engine
The Hesselman engine is a hybrid between a petrol engine and a diesel engine. It was designed and introduced in 1925 by Sweden, Swedish engineer Jonas Hesselman. In a Hesselman engine, fuel is not injected during the suction stroke along with the air, as would be the case in a conventional Otto cycle engine, but is instead injected during the compression stroke slightly ahead of the spark. Hesselman engines typically have lower efficiencies than diesel engines but can run on the same fuels without needing to sustain high compression ratios, and therefore could be made smaller, lighter and cheaper. Most Hesselman engines were built during the 1930s and 1940s by firms in Sweden and the United States for use in both heavy vehicles and stationary industrial applications. Operation During the engine's operating cycle, air is first drawn into the cylinder through an intake valve and given a rotary motion as a result of its tangential direction of entry. Air is compressed on the " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Thomas Tilling
The Tilling Group was one of two conglomerates that controlled almost all of the major bus operators in the United Kingdom between World Wars I and II and until nationalisation in 1948. Tilling, together with the other conglomerate, British Electric Traction (BET), became the main constituents of the country's nationalised bus industry in the late 1960s and was sufficiently well known to have entered popular culture as part of London's Cockney rhyming slang (Thomas Tilling = shilling). The company continued as an industrial conglomerate after the nationalisation of its bus interests; it was acquired by BTR plc in 1983. Origins The company traces its origins to 1846, when Thomas Tilling started in business. Tilling was born in 1825 at Gutter's Hedge Farm, Hendon, Middlesex, of parents who had moved there from Gloucestershire. In 1846, at the age of 21, he went into the transport business in London as a jobmaster in Walworth using a horse and carriage which cost him £30. ...

Daimler-Motoren-Gesellschaft
Daimler-Motoren-Gesellschaft (abbreviated as DMG, also known as Daimler Motors Corporation) was a German engineering company and later automobile manufacturer, in operation from 1890 until 1926. Founded by Gottlieb Daimler (1834–1900) and Wilhelm Maybach (1846–1929), it was based first in Cannstatt (today Bad Cannstatt, a city district of Stuttgart). Daimler died in 1900, and their business moved in 1903 to Stuttgart- Untertürkheim after the original factory was destroyed by fire, and again to Berlin in 1922. Other factories were located in Marienfelde (near Berlin) and Sindelfingen (next to Stuttgart). The enterprise began to produce petrol engines but after the success of a small number of race cars built on contract by Wilhelm Maybach for Emil Jellinek, it began to produce the Mercedes model of 1902. After this automobile production expanded to become DMG's main product, and it built several models. Because of the post World War One German economic crisis, in 1926 D ...

Mercedes-Benz Buses
Mercedes-Benz has been producing buses since 1895 in Mannheim in Germany. Since 1995 Mercedes-Benz buses and coaches are known by the brand name of Daimler Buses (formerly EvoBus GmbH), a wholly owned subsidiary of Daimler Truck. Heritage The world's first motorised bus was built in Germany by Karl Benz in 1895, some years before Gottlieb Daimler also started to build and sell buses in Germany as well. By 1898, both Karl Benz and Gottlieb Daimler, then rivals, were exporting their buses to Wales and England. Soon, Daimler products were sold in the British Empire in a partnership with the British company Milnes. Milnes-Daimler developed a double-decker bus, double-decker in 1902 and provided a bus for the first motorised bus service in the United Kingdom the following year. Though the company met success in selling buses throughout the British Empire, the partnership between Daimler and Milnes had to be undone due to the First World War. Due to economic hardships in the early 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Stationary Engine
A stationary engine is an engine whose framework does not move. They are used to drive immobile equipment, such as pumps, generators, mills or factory machinery, or cable cars. The term usually refers to large immobile reciprocating engines, principally stationary steam engines and, to some extent, stationary internal combustion engines. Other large immobile power sources, such as steam turbines, gas turbines, and large electric motors, are categorized separately. Stationary engines, especially stationary steam engines were once widespread in the late Industrial Revolution. This was an era when each factory or mill generated its own power, and power transmission was mechanical (via line shafts, belts, gear trains, and clutches). Applications for stationary engines have declined since electrification has become widespread; most industrial uses today draw electricity from an electrical grid and distribute it to various individual electric motors instead. Engines that operate i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Locomotive
A locomotive is a rail transport, rail vehicle that provides the motive power for a train. Traditionally, locomotives pulled trains from the front. However, Push–pull train, push–pull operation has become common, and in the pursuit for longer and heavier freight trains, companies are increasingly using distributed power: single or multiple locomotives placed at the front and rear and at intermediate points throughout the train under the control of the leading locomotive. Etymology The word ''locomotive'' originates from the Latin language, Latin 'from a place', Ablative case, ablative of 'place', and the Medieval Latin 'causing motion', and is a shortened form of the term ''locomotive engine'', which was first used in 1814 to distinguish between self-propelled and stationary steam engines. Classifications Prior to locomotives, the motive force for railways had been generated by various lower-technology methods such as human power, horse power, Gravity railroad, g ...

Light Railway
A light railway is a Rail transport, railway built at lower costs and to lower standards than typical "heavy rail": it uses lighter-weight track, and may have more Grade (slope), steep gradients and Minimum railway curve radius, tight curves to reduce civil engineering costs. These lighter standards allow lower costs of operation, at the price of lower vehicle capacity. Narrow gauge The precise meaning of the term "light railway" varies by geography and context. In countries where a single standard gauge is dominant, the term light railway does not imply a narrow gauge railway. Most narrow gauge railways operate as light railways, but not all light railways need be narrow gauge. After Charles Easton Spooner, Spooner's development of steam haulage for narrow gauge railways, the prevailing view was that the gauge should be tailored according to the traffic: "The nearer the machine is apportioned to the work it has to do the cheaper will that work be done." From the 1890s, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Tractor
A tractor is an engineering vehicle specifically designed to deliver a high tractive effort (or torque) at slow speeds, for the purposes of hauling a Trailer (vehicle), trailer or machinery such as that used in agriculture, mining or construction. Most commonly, the term is used to describe a farm vehicle that provides the power and traction to mechanization, mechanize agricultural tasks, especially (and originally) tillage, and now many more. List of agricultural machinery, Agricultural implements may be towed behind or mounted on the tractor, and the tractor may also provide a source of power if the implement is mechanised. Etymology The word ''tractor'' was taken from Latin, being the Agent (grammar), agent noun of ''trahere'' "to pull". The first recorded use of the word meaning "an engine or vehicle for pulling wagons or plows" occurred in 1896, from the earlier term "traction engine, traction motor" (1859).

Fishing Vessel
A fishing vessel is a boat or ship used to fishing, catch fish and other valuable nektonic aquatic animals (e.g. shrimps/prawns, krills, coleoids, etc.) in the sea, lake or river. Humans have used different kinds of surface vessels in commercial fishing, commercial, artisan fishing, artisanal and recreational fishing. Prior to the 1950s there was little standardisation of fishing boats. Designs could vary between localities and even different boatyards. Traditional fishing boats were built of wood, which is not often used nowadays because of higher maintenance costs and lower durability. Fibreglass is used increasingly in smaller fishing vessels up to 25 metres (100-tonne displacement), while steel is usually used on vessels above 25 metres. It is difficult to estimate the number of recreational boat fishing, recreational fishing boats. They range in size from small dinghies, sailboats and motorboats to large superyachts and chartered cruiseliners. Unlike commercial fishing vess ...

Motor Boat
A motorboat or powerboat is a boat that is exclusively powered by an engine; faster examples may be called "speedboats". Some motorboats are fitted with inboard motor, inboard engines, others have an outboard motor installed on the rear, containing the internal combustion engine, the gear reduction, gearbox and the propeller in one portable unit. An sterndrive, inboard-outboard contains a hybrid of an inboard and an outboard, where the internal combustion engine is installed inside the boat, and the gearbox and propeller are outside. There are two configurations of an inboard, V-drive and direct drive. A direct drive has the powerplant mounted near the middle of the boat with the propeller shaft straight out the back, where a V-drive has the powerplant mounted in the back of the boat facing backwards having the shaft go towards the front of the boat then making a ''V'' towards the rear. Overview A motorboat is a small craft with one or more engines for propulsion. Motorboats ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Vaporization
Vaporization (or vapo(u)risation) of an element or compound is a phase transition from the liquid phase to vapor. There are two types of vaporization: evaporation and boiling. Evaporation is a surface phenomenon, whereas boiling is a bulk phenomenon (a phenomenon in which the whole object or substance is involved in the process). Evaporation Evaporation is a phase transition from the liquid phase to vapor (a state of substance below critical temperature) that occurs at temperatures below the boiling temperature at a given pressure. Evaporation occurs ''on the surface''. Evaporation only occurs when the partial pressure of vapor of a substance is less than the equilibrium vapor pressure. For example, due to constantly decreasing pressures, vapor pumped out of a solution will eventually leave behind a cryogenic liquid. Boiling Boiling is also a phase transition from the liquid phase to gas phase, but boiling is the formation of vapor as bubbles of vapor ''below the surface'' of ...
