Intro to I.C Engines

HEAT ENGINE

Heat engine is a device which operates by conversion of chemical energy into mechanical energy which is used to do mechanical work.Heat engines are classified into two types.

1)Internal combusion Engines(I.C Engines)
2)External combusion Engines(EC Engines)

Internal Combustion Engines
  The combustion of fuel takes place inside the engine cylinder and produces the high thermal energy.
     Example:Petro engines,Diesel engines

External Combustion Engines
 The combusion of fuel takes place outside the engine and transfers the heat by a medium to operate the cylinder.
   Example:Steam engine
