In the UK a Gas engine means an engine running on gas, such as coal gas or producer gas. It does not include a gasoline engine which, in the UK, is called a Petrol engine. US usage may be different. Syngas (from synthesis gas) is the name given to gasses of varying composition that are generated in coal gasification and some types of waste-to-energy facilities. ... Producer Gas is a generic term refering to: Wood gas : produced in a gasifier to power cars with ordinary internal combustion engines. ... Gasoline (or petrol) engine is a type of internal combustion engine which is often used for automobiles, aircraft, small mobile vehicles such as lawnmowers or motorcycles, and outboard motors for boats. ... United States may refer to: Places: United States of America SS United States, the fastest ocean liner ever built. ...
A gas engine differs from a petrol engine in the way the fuel and air are mixed. A petrol engine uses a carburettor or fuel injection but a gas engine uses a three-valve system with separate inlet valves for air and gas. The carburetor (or carburettor, carb for short) is a device which mixes air and fuel for an internal_combustion engine. ... // Fuel injection is a means of metering fuel into an internal combustion engine. ...
The best known builder of gas engines in the UK was Crossley. Crossley Motors, based in Manchester, England, produced approximately 19,000 high quality cars from 1904 until 1938, 5,500 buses from 1926 until 1958 and 21,000 goods and military vehicles from 1914 to 1945. ...
The internal combustionengine is a heatengine in which the burning of a fuel occurs in a confined space called a combustion chamber.
For high performance gasolineengines using current materials and technology (such as the engines found in modern automobiles), there seems to be a break point around 10 or 12 cylinders, after which addition of cylinders becomes an overall detriment to performance and efficiency, although exceptions such as the W16 engine from Volkswagen exist.
A gas turbine, also called a combustion turbine, is a rotaryengine that extracts energy from a flow of combustiongas.
Gas turbines are described thermodynamically by the Brayton cycle, in which air is compressed isentropically, combustion occurs at constant pressure, and expansion over the turbine occurs isentropically back to the starting pressure.
Gas turbines are used in many naval vessels, where they are valued for their high power-to-weight ratio and their ships' resulting acceleration and ability to get underway quickly.
