Lesson: Most Common Car Parts (Beginner Guide)
Engine
The engine is the heart of the car. It turns fuel into power that moves the vehicle.
Common engine parts:
- Cylinder – Where fuel burns to create power
- Pistons – Move up and down to turn energy into motion
- Crankshaft – Converts piston movement into rotation
- Spark plugs – Ignite the fuel-air mixture
- Timing belt/chain – Keeps engine parts in sync
Transmission
The transmission sends power from the engine to the wheels and controls speed.
- Automatic transmission – Shifts gears by itself
- Manual transmission – Driver shifts gears using a clutch
- Clutch – Connects and disconnects engine power (manual cars)
Fuel System

- Fuel tank – Stores gasoline
- Fuel pump – Pushes fuel to the engine
- Fuel injectors – Spray fuel into the engine
- Fuel filter – Keeps dirt out of the fuel

Prevents the engine from overheating.
- Radiator – Cools engine fluid
- Coolant – Absorbs heat
- Water pump – Circulates coolant
- Thermostat – Regulates temperature
Exhaust System
Removes harmful gases and reduces noise.
- Exhaust manifold – Collects gases from engine
- Catalytic converter – Reduces emissions
- Muffler – Quietens the sound
- Exhaust pipe – Releases gases outside
Braking System
Helps the car slow down and stop safely.
- Brake pedal – Activates brakes
- Brake pads – Create friction
- Rotors – Slow wheel rotation
- Calipers – Press pads against rotors
Suspension & Steering
Controls comfort and handling.
- Shocks/struts – Absorb bumps
- Springs – Support vehicle weight
- Control arms – Connect wheels to frame
- Steering wheel – Controls direction
- Tie rods – Turn the wheels
Electrical System
Powers lights, electronics, and engine components.
- Battery – Stores electrical power
- Alternator – Charges the battery
- Starter motor – Starts the engine
- Fuses – Protect electrical circuits
Basic Maintenance Parts
