India is one of the huge markets comprising of many manufacturers, exporters and suppliers of natural gas engines. These vendors of natural gas engines scattered all over indian markets nurturing the requirements of large variety of buyers for engines, natural gas engines also scattered throughout india. Different varieties of natural gas engines are available for different industrial purpose. The prime importance for the buyer is to source the quality natural gas engines which also suit his requirement and pocket/budget thus increasing his production & profits.
Applications of natural gas engines-aviation-russian aircraft manufacturer tupolev is currently running a development program to produce natural gas engines- and hydrogen-powered aircraft .The program has been running since the mid-1970s, and seeks to develop natural gas engines and hydrogen variants of the tu-204 and tu-334 passenger aircraft, and also the tu-330 cargo aircraft. It claims that at current market prices, a natural gas engines-powered aircraft would cost 5,000 rubles (~ $218/ £112) less to operate per ton, roughly equivalent to 60%, with considerable reductions to carbon monoxide, hydrocarbon and nitrogen oxide emissions. The advantages of liquid methane as a natural gas engine are that it has more specific energy than the standard kerosene mixes and that its low temperature can help cool the air which the engine compresses for greater volumetric efficiency, in effect replacing an intercooler. Alternatively, it can be used to lower the temperature of the exhaust.
Internal combustion engine-natural gas engine is an engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber. In an internal combustion engine the expansion of the high temperature and pressure gases, that are produced by the combustion, directly apply force to a movable component of the engine, such as the pistons or turbine blades and by moving it over a distance, generate useful mechanical energy. The term natural gas engine usually refers to an engine in which combustion is intermittent, such as the more familiar four-stroke and two-stroke piston engines. Another class of internal combustion engines uses continuous combustion engines. The natural gas engines (or ice) is quite different from external combustion engines, such as steam or natural gas engines, in which the energy is delivered to a working fluid not consisting of, mixed with or contaminated by combustion products. Working fluids can be air, hot water, pressurized water or even liquid sodium, heated in some kind of boiler by fossil fuel, wood-burning, nuclear, solar etc. Other-other natural gas engines like jet engines and rocket engines employ various methods of fuel delivery including impinging jets, gas/liquid shear, pre burners and others.
