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:
1. Steam engine
. Stationary application
. Transporting application
2. Diesel engine
. Military fuel standardization
. Other transport uses
3. Concentrating Solar Power (CSP):

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.
