External Combustion Engines Clssification

1Faculty of EngineeingMechanical Power Department External Combustion EnginesIntroduction 1Early transportation vehicles relied on animal power, wind and flowing water. With the motorization of transportation vehicles, combustible fuels became important sources of energy.Heat engines, such as the steam engine (piston and turbine), played an important role in water and rail transport during much of the 19th century and early part of the 20th century.4What is heat engine ??Definition How its work ?types5A heat engine is a system which converts heat into work6Engines take heat from the reservoir ( hot body) to carry out some work. There is a discharge of some heat to the sink (cold body). In this system, there will also be some waste in the form of heat. There are different types of a heat engine in which a Carnot engine has the maximum efficiency78Heat EnginesExternal Combustion EnginesInternal Combustion EnginesExternal Combustion EnginesHere the fuel gets burned outside the engine or at a far distance from the engine by which it can produce force and motion. A very good example of an external combustion engine is a steam engine.Then what is the difference ??Internal Combustion EnginesHere the fuels are burned inside the chamber.
