VIDEO LECTURE ON ENGINE AND ITS CLASSIFICATIONS
ENGINE
What is engine ?
- It is a power generating machine which converts power into motion.
- Otherwise we can define as, engine is a device which converts heat energy of the fuel into mechanical energy.
Example : Petrol engine, Diesel engine

INTERNAL COMBUSTION ENGINE |
What is heat engine?
Heat engine is a device which converts heat energy into work.
Example: IC engine, EC engine
![]() |
EXTERNAL COMBUSTION ENGINE |
What is IC engine ?
- IC engine also called as internal combustion engine.
- The combustion of fuel takes place inside of the cylinder.
- During combustion process, chemical energy of the fuel is converted into heat energy. Further it is converted into useful work.
Example : Petrol engine, Diesel engine, Gas turbine.

TURBINE |
What is EC engine ?
- EC engine also called as external combustion engine.
- The combustion of fuel takes place externally.
- In external combustion engine heat energy is converted into mechanical work.
Example : Steam turbines used in thermal power plant. Gas turbine power plant.
