3. Introduction Heat Engine Concept   What is Heat Engine ?

4. History In 1824 - Nicolas Léonard Sadi Carnot who is French mechanical engineer in the French Army, developed the Carnot cycle and the associated hypothetical Carnot heat engine that is the basic theoretical model for all heat engines.

5. How Heat Engine Work? Each process in heat engine is one of the following:  Isothermal Isometric Isobaric Adiabatic Isentropic

6. how heat engine works (video):

7. Efficiency  The efficiency of an engine is defined as ratio of the useful work done to the heat provided.  

8. Types Of Heat Engine There are mainly two types of heat engines: External combustion engine Beam engines (atmospheric engines) Steam engines Stirling engines Internal combustion engine Gasoline (petrol) engines Diesel engines Rotary engines

9. Applications   of heat engine :

10. Advantage & Disadvantages Of Heat Engine Advantages:   -Most important things we can do with heat is to use it to do work for us. -Approximately 90 percent of the world’s electricity is generated by heat energy. Disadvantages: -pollution problems   -The limitation of efficiency -High cost -strength and resistance of piston

11. Conclusion Heat Engine transform heat to work. Work on a principal, that transfer heat from high to a lower temperature. The main idea of efficiency, is to making the best possible use of available resources. It has two main types and each of them have its applications, advantage and disadvantages.
