| External combustion engine | An external combustion engine is an engine which burns its fuel to heat a separate working fluid which then in turn performs work. Examples include steam engines and Stirling engines. External combustion engines are often less compact and less powerful than internal combustion engines, but are sometimes more efficient, and are much less particular about the type of fuel they burn. They also tend to be cleaner due to lower combustion temperatures and pressures which create less exotic exhaust gasses, such as nitrogen oxides(NO, NO2 etc.). (references) | ||
