4. Intake Valve:- opens at the proper time to let in air and fuel.

6. Doorway that lets the gases in and out ofthe engine. 6

7. Lower End Action 7

8. Valve Cover:- Protects the valves and thevalve springs. Keeps dirt out and lubricating oil in.

10. Cylinder Head:- a platform containing most of the parts of the combustion chamber. Forms the top of the combustionchamber. Contains the valves, the passageways for the fuel mixture to move in and out of the engine.

12. BASIC COMPONENTS Intake Valve Valve Cover Intake Port Head Coolant Engine Block Oil Pan Oil Sump Crankshaft Camshaft Exhaust Valve Spark Plug Exhaust Port Piston Connecting Rod Rod Bearings

13. Coolant:- circulating water and antifreeze to keepthe temperature regulated.

15. Engine Block- cast in one piece. The basis for most of the parts of the engine.

17. Oil Pan- where the oil is collected andrecirculated.

19. Oil Sump:- the collected oil primarily forlubricating the crankshaft and rod bearing

21. Camshaft:- a round shaft with lobes, that rotates to open and close the fuel and exhaust valves. Through the use of an eccentric the cam lobes push the valves open. The valve springs closethem.

22. 22

24. Exhaust Valve- open at the proper time torelease the exhaust

25. Lower End Action 25

27. Spark Plug a device, inserted into the combustion chamber for firing an electrical spark to igniteair-fuel mixture SPARK PLUG ( PETROLENGINE )

28. Electric match used to begin the combustion process of burning air and gasoline to create heat. 28

29. INJECTOR ( FOR DIESEL) Fuel injection is a system for admitting fuel into an internalcombustion engine ( Diesel Engine )

31. Piston- the part of the engine that moves up and down in the cylinder converting the gasoline into motion

32. Know Your Piston!

33. PistonRings:- The rings seal the compression gases abovethe piston keep the oil below the piston rings.

35. Piston Pins:- Also known as the wrist pin, it connects the piston to the small end of the connecting rod. It transfers the force and allows the rod to swing back and forth.

37. Connecting Rod- links the piston to thecrankshaft.

39. Rod Bearing- used to reduce friction to the rodand crankshaft

41. Crankshaft- converts the up and down motion ofthe piston into a turning, or rotatingmotion

42. Along the the piston pin and connecting rod it converts the up and down motion (reciprocating) of the engine to spinning (rotary) motion. 41

43. RELATION BETWEEN PISTON, CONNECTING ROD & CRANK SHAFT

45. Flywheel :- Carries the inertia when there isno power stroke. 44

46. GASKET A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objectswhile under compression

47. WATER PUMP The water pump is a simple centrifugal pump driven by a belt connected to the crankshaft of the engine. The pump circulates fluid whenever the engine is running.
