 Parts of an Automobile:-

Every Automobile consists of the following two main parts:-

1. Machine portion.
2. Carriage portion.

Machine Portion:-

Every automobile, irrespective of its country of manufacturing or mode,l consists of the following three basic units:

• The "chassis and transmission".
• The "engine".
• The "electrical equipment".

* Chassis and Transmission:-

Chassis:-

• This part of the automobile supports its body, engine and transmission system.
• The automotive chassis includes the following:-

     - The Frame.

     - Springs and shock absorbers.

     - Steering system.

     - Brakes.

     - Tyres and wheels.

Transmission:-

• This unit transmits the power from the engine to the wheels.
• It consists of the following:

     - Clutch.

     Gearboxox.

     - Universal joint.

     - Final drive.

     - Axles and differential.

* The Engine:- 

The engine in an automobile is the source of power. A petrol engine consists of the following four basic systems, described briefly below:

• Full system:- This system mixes petrol with air in the right proportion to give a mixture which, when burned,t produces pressure. This pressure is then used to move the piston.
• Ignition system:- This system of the engine provides regular sparks to set fire to the mixture coming from the fuel system. 
• Lubricating system:- This system lubricates the moving parts of the engine so that they can work smoothly.
• Cooling system:- This system, with the help of water,r cools the engine and prevents it from getting hot.

> Diesel engines incorporating similar/different systems are also used in automobiles.

The Electric Equipment:-

The automotive electrical system consists of the following:-

• The Battery.
• Dynamo.
• Alternators.
• The ignition, starting,g and lighting systems.

> Thisystemms starts the engine when the ignition switch is turned on. It makes the spark that ignites the compressed sir-fuel mixture.

> It also operates the electric gauge head lights, indicator lights, brake lights, parking lights, wipers and also radio and cassette recorders in some cars.

Body or Carriage Portion:-

• It is the portion of an automobile where passengers have their seats or where the cargo to be carried is placed.
• The body is designed according to the nature of the cargo to be carried. The body of a passenger carrier is much different from the body of a load carrier, i.e., a truck. It's designed depending on the utility for which the vehicle is meant. It is made of either wood and steel or steel alone. Modern research has led to the development of plastic bodies.
• In trucks, tractors and certain other vehicles, a separate cabin known as 'Cab' is provided for the driver where the instrument panel and controls are housed.
