3. Definition of Engine
The engine of a car or other vehicle is the part that produces the power which makes the vehicle move.
※Classification
Oil : Gasoline Engine, Diesel Engine
Shapes: V-Engine (V형), Inline Engine (직렬), W-Engine (W형), Flat Engine(=Boxer Engine,수평)

4. Intake Principle of Engine
The air ,which be came into intake pipe be mixed with fuel, which is spraied from injector . The gas mixture enter a room of cylinder that intake valve is opened by cam shaft

5. Compression Principle of Engine
First intake valve is closed and than the gas mixture is compressed by lifting piston

6. Explode Principle of Engine
Explode is happened a room of cylinder because of spike at plug and the explode make piston down

7. Exhaustion Principle of Engine
Exhaustion valve is opened and then gas get out to repeat again process of intake

8. Components of Engine Piston Head Crank Shaft Connecting Rod
