- Pistons: Move up and down to generate power.
- Crankshaft: Converts piston movement into rotational energy.
- Camshaft: Controls valve timing for air and fuel intake.
- Timing Belt/Chain: Synchronizes camshaft and crankshaft.
- Spark Plugs: Ignite the air-fuel mixture.
- Fuel Injectors: Spray fuel into the combustion chamber.
- Oil Filter: Removes contaminants from engine oil.
Transmission System
The transmission transfers power from the engine to the wheels.
- Clutch (Manual): Engages/disengages engine from transmission.
- Torque Converter (Automatic): Replaces clutch in automatic cars.
- Gearbox: Contains gears for speed and torque control.
- Driveshaft: Transmits torque to the wheels.
- Differential: Allows wheels to rotate at different speeds.
Suspension and Steering
These parts ensure a smooth ride and responsive handling.
- Shock Absorbers: Reduce impact from road bumps.
- Struts: Support the suspension system.
- Control Arms: Connect wheels to the frame.
- Steering Rack: Converts steering wheel motion to wheel movement.
- Tie Rods: Link steering rack to wheels.
Brake System
Safety starts with reliable brakes.
- Brake Pads: Press against rotors to stop the car.
- Brake Rotors: Discs that brake pads clamp onto.
- Calipers: House brake pads and apply pressure.

Body and Exterior
The outer shell protects and defines your car’s look.
- Bumper: Absorbs impact in collisions.
- Fenders: Cover wheel wells.
- Grille: Allows airflow to the radiator.
- Hood: Covers the engine bay.
- Trunk: Rear storage compartment.
- Doors: Entry and exit points.
Exhaust System
Manages emissions and noise.
- Exhaust Manifold: Collects gases from cylinders.
- Catalytic Converter: Reduces harmful emissions.
- Muffler: Dampens engine noise.
- Tailpipe: Releases exhaust gases.
Final Thoughts
Understanding the names of car parts empowers you to take better care of your vehicle. Whether you’re troubleshooting a problem or upgrading your ride, this knowledge is your first step toward becoming a confident car owner.
