This document provides an overview of the key components and systems of an automobile. It discusses the engine, including the internal combustion process and different engine types. It also describes the fuel system, transmission components like the clutch and gearbox, braking system including disc and drum brakes, and other systems such as steering, suspension, battery, and electrical components. The document aims to introduce the major mechanical parts that work together to power and control a vehicle.

1. An automobile description

2. Engine details
Fuel distribution
What is Crankshaft ?
Gear box & clutch details
About the carburetor
Brake system details

3. Introducing a car

4. ENGINE
An important part where
the mechanism occurs
An engine or motor is
a machine designed to
convert energy into
useful mechanical motion

5. WHAT HAPPENS IN A ENGINE

6. That big chunk of metal known as the engine block has to carry every
part of the engine,
The internal combustion engine is an engine in which the combustion of a fue
occurs with an oxidizer in a combustion chamber that is an integral part of the
working fluid flow circuit. ships heavy duty machinery, motorcycles, automobiles
boats, trucks aircraft
TWO TYPES OF ENGINES
1.INTERNAL COMBUSTION
2.EXTERNAL COMBUSTION
An external combustion engine (EC engine) is a heat engine where an interna
working fluid is heated by combustion,i,e. combustion take place out side comb
chamber of the engine. Example- Steam Engine.

7. Watt steam engine was the first
type of steam engine(1712)

8. Different engines

9. 4 stroke engine working(Ice)
1.intake
2.compression
3.power
4.exhaust
Petrol Engine invented by NICOLAS

10. 2 stroke engine operation
Used in chainsaws and outboard motors,
A two-stroke, engine is a type of internal combustion engine
which completes a power cycle in only one crankshaft

11. Fuel pump

12. injectors
petrol diesel

13. 4 stroke engine operation

14. Piston assembly

15. Crankshaft

16. Camshaft timing belts

17. A timing belt, or cam belt (informal usage), is a part
of an internal combustion engine that controls the
timing of the engine's valves.

18. Belts and belt tensioners work
together to keep various
components of your car engine
running, such as the water
pump, alternator, power steering
and air conditioner.

19. Over head view of camshaft

20. A car belt tensioner is a metal,
spring-loaded pulley that
attaches to the engine.

21. Gear box

22. TORQUE CONVERTER.
Used as Automatic
transmissions on
automobiles, such as
cars, buses, and on/off
highway trucks

23. CLUTCH
for regulating torque
transfer from the internal
combustion engine to the
transmission; and a gear
stick,

24. How a clutch and gear
connected

25. HOW ENGINE IS
CONNECTED TO WHEELS
Front wheels

26. Carburetor and its jets

27. Air filter

28. Brake system

29. Disc brake & brakes drum
Frictional brakes
Pumping brakes
Electromagnetic brakes

30. Inner view of drum brake

31. DISC BRAKE
A metal disk that spins
with the wheel that the
brake pad uses to
Pressure against
to stop.

32. AIR CON
Used for cooling of engine

33. C-v joint(constant-velocity)

34. steering setup in a car

35. differential

36. transmission setup to a car

37. ALTERNATOR
Recharges the battery
and supplies power to all
electrical components.

38. Lead acid battery

39. Starts the car by taking dc
input

40. Down view

41. DISTRIBUTOR
A distributor is a device in the
ignition system of an internal
combustion engine that routes
high voltage from the ignition
coil to the spark plugs in the
correct firing order

42. filler cap: the small round lid that covers the hole where you put the petrol
in a car or other vehicle
Silencer: an object that reduces the noise from a vehicle’s engine.
The American word is muffler.
scavenging is the process of pushing exhausted gas-charge out of the cylinde
and drawing in a fresh draught of air ready for the next cycle.
