Basics of Automobile Technology An Introduction for 9th Standard Students Presented by: Dr. N. Shanmuga Sundaram
What is an Automobile? An automobile is a self-propelled vehicle used for transporting people or goods. Examples: Cars, Buses, Trucks, Motorcycles.
History of Automobiles • 1769 – First steam-powered vehicle • 1886 – Karl Benz invented the first petrol-powered car • 1908 – Ford Model T introduced mass production • Today – Electric and autonomous vehicles
Main Parts of an Automobile 1. Chassis 2. Engine 3. Transmission System 4. Braking System 5. Steering System 6. Suspension System 7. Electrical System 8. Body
Chassis and Body • Chassis: The main frame of the vehicle that supports all components • Body: Covers and protects the chassis and passengers
Engine – The Heart of the Vehicle • Converts fuel into power • Types of engines: Petrol, Diesel, Electric • Main parts: Cylinder, Piston, Crankshaft, Valves
Types of Engines • Internal Combustion Engine (ICE) • External Combustion Engine • Electric Motor (used in EVs) Classification based on: - Fuel used - Number of cylinders - Cooling method
Fuel System • Supplies fuel to the engine • Components: Fuel tank, fuel pump, carburetor/injector, fuel filter • Modern vehicles use fuel injection systems
Cooling and Lubrication Systems Cooling System: - Removes excess heat from the engine - Uses water or air cooling Lubrication System: - Reduces friction between moving parts - Uses engine oil
Transmission System • Transfers power from the engine to the wheels • Components: Clutch, Gearbox, Propeller shaft, Differential • Types: Manual and Automatic transmission
Braking System • Slows down or stops the vehicle • Types: Disc brakes, Drum brakes, ABS (Anti-lock Braking System) • Essential for safety
Steering System • Helps the driver control direction • Components: Steering wheel, column, gearbox, linkage • Power steering reduces driver effort
Suspension System • Connects the wheels to the chassis • Provides comfort by absorbing shocks • Components: Springs, Shock absorbers, Linkages
Electrical System • Provides power for lights, horn, starter motor, and accessories • Components: Battery, Alternator, Wiring, Fuses
Modern Automobile Technologies • Electric Vehicles (EVs) • Hybrid Vehicles • Autonomous (Self-driving) Cars • Connected and Smart Vehicle Systems
Safety Features • Seat belts • Airbags • Anti-lock Braking System (ABS) • Electronic Stability Control (ESC) • Crumple zones
Future of Automobiles • Fully electric transportation • Solar-powered vehicles • Advanced driver assistance • Eco-friendly materials
Quiz Time! 1. What is the main function of the engine? 2. What are the two main types of brakes? 3. Name one modern automobile technology. 4. What connects the wheels to the chassis?
Summary • Automobiles are complex machines made up of many systems • Each system performs a specific function • Modern technology is making vehicles safer and eco-friendly Thank You!
