Study Notes

Electrical System

  • The electrical system in an automobile consists of:
    • Battery: provides power to the vehicle's electrical systems
    • Alternator: generates electricity to recharge the battery and power the vehicle's systems
    • Starter motor: uses electrical energy to start the engine
    • Fuses and relays: protect the electrical system from overload and distribute power to various components

Brakes

  • Types of brakes:
    1. Disc brakes: use a rotor and caliper to slow the vehicle
    2. Drum brakes: use a drum and shoes to slow the vehicle
  • Brake components:
    • Brake pedal: actuates the brake system
    • Brake master cylinder: converts non-hydraulic pressure into hydraulic pressure
    • Brake fluid: transfers pressure from the master cylinder to the brake calipers or wheel cylinders

Differential

  • The differential is a gearbox that:
    • Transfers power from the transmission to the wheels
    • Allows the wheels to rotate at different speeds
    • Enables the vehicle to turn smoothly
  • Types of differentials:
    1. Open differential: allows power to be distributed equally to both wheels
    2. Locked differential: locks both wheels together, providing maximum traction
    3. Limited-slip differential: transfers power to the wheel with the most traction

Engine

  • Types of engines:
    1. Internal combustion engine: uses a combination of air, fuel, and spark to generate power
    2. Hybrid engine: combines an internal combustion engine with an electric motor
    3. Electric engine: uses electric motors to generate power
  • Engine components:
    • Cylinders: where the combustion process takes place
    • Pistons: move up and down, driven by the combustion process
    • Crankshaft: converts the up-and-down motion of the pistons into rotary motion

Gear

  • Types of gears:
    1. Manual transmission: uses a manual shift lever to change gears
    2. Automatic transmission: uses a complex system of gears and clutches to change gears
    3. Semi-automatic transmission: combines elements of manual and automatic transmissions
  • Gear components:
    • Gearbox: contains the gears and bearings
    • Clutch: engages and disengages the engine from the transmission
    • Gear ratios: determine the speed and torque of the vehicle
