  6. ENGINE In an External combustion engine, the products of the combustion transfer the heat to working fluid, through the engine wall or a heat exchanger whereas in Internal combustion engine the products of combustion produces the power directly in the same cylinder.

  7. Advantages of IC Engine over EC Engine :- Mechanical simplicity . Low initial cost (boiler absent) . Lower weight to power ratio . Higher efficiency

  8. IC ENGINE: Spark ignition engine :- SI Engine Compression ignition engine :- CI Engine 5*

  9. Spark plug or fuel injector Engine nomenclature :- Valve Top ead center Clearance volume Bore Cylinder wall Stroke Bottom dead center Piston Reciprocating motion Crank mechanism Rotary motion
