3. Heat Engine Internal Combustion Engine (IC Engine) External Combustion Engine (EC Engine)

4. Internal Combustion Engine (IC Engine) An IC Engine  is a heat  engine  in which the  combustion of a fuel  (normally a fossil fuel Eg ; Petrol, Diesel, LPG etc) occurs with in a  combustion chamber (Engine cylinder).  

5. The   internal combustion engines (IC Engines) are classified depending upon Nature of Thermodynamic Cycle Type of Fuel Number of Strokes Type of Ignition Number of Cylinders Position of the Cylinder Type of Cooling Classification of IC Engines

6. The   internal combustion engines (IC Engines) are classified depending upon Nature of Thermodynamic Cycle Otto Cycle Engine Diesel Cycle Engine Dual Combustion Cycle Engine Classification of IC Engines

7. The   internal combustion engines (IC Engines) are classified depending upon Type of Fuel Petrol Engine Diesel Engine Gas Engine ( CNG or LPG or biogas or Hydrogen etc) Number of Strokes 2 – Stroke Engines 4 – Stroke Engines Classification of IC Engines

8. The   internal combustion engines (IC Engines) are classified depending upon Type of Ignition Spark Ignition (SI Engine) Compression Ignition (CI Engine) Number of Cylinders Single Cylinder Multi-cylinder Classification of IC Engines

9. The   internal combustion engines (IC Engines) are classified depending upon Position of the Cylinder Horizontal Engine Vertical Engine Radial Engine V – Engine Opposite Cylinder Engine Type of Cooling Air-Cooled Engine Water Cooled Engine Classification of IC Engines
