Application Of Internal Combustion Engine

Internal combustion engine, a type of heat engine mostly refers to reciprocating engine. Fuel mixture and air is burnt in very small and confined space by combustion. Exothermic reaction results in increase of pressure and temperature. Internal combustion engine is capable of converting chemical fuel energy in to mechanical energy. Depending on the application type, internal combustion engine are designed. Internal combustion engine finds its own major application in mobile propulsion system. The use of engine in mobile state of affairs ensures more power to weight ratio in addition to excess fuel energy density.

Internal combustion engine is now widely used in number of automobiles, aircraft vehicles, motorbikes, boats and other similar locomotives. Automobiles such as helicopters, big barges and ships and jet crafts utilize excess power which is supplied in the form of gas turbines. Gas turbines are especially used in major power plants and similar naval applications. It is also used for minor power applications. Majority of the industries today have general electric motors which are of internal combustion type. Competitive technology of electric motor invention is used in power automobiles such as low power automobiles and non automobiles. Battery operated electric vehicles have hybrid internal combustion engine technology. Batteries are made of Lithium ion and Lithium poly chemistry and are of safe, cost efficient and has increased life expectancy.

Compression ratio can be varied depending on the operation principle like temperature, fuel type and equivalence ratio of internal combustion engine. If one of the parameter is altered as desired, then compression ratio of interest is obtained. The mechanical friction between crankshaft and connecting rod is negligible. Use of piston dynamics improves the quality of engine oil and emissions such as NOx.
