ME 100 Basics of Mechanical Engineering Module 2 : 'IC Engines'


Heat Engine:-

IC Engine is a classification of Heat engine So we have to study only IC Internal Combustion Engine.
A device which convert thermal energy into mechanical energy
Heat Engine classification (Based on type of combustion)

       1.  External Combustion Engine (E C Engine)

             - In an EC Engine, combustion of fuel takes place out side the cylinder.
 eg: Steam engines
       2.  Internal combustion Engine ( I C Engine)
              - In an IC Engine, combustion of fuel takes place in side the cylinder.
 eg: Automobile engines
