Study Notes
Engine Repair
-
Engine Components:
- Cylinders: where combustion takes place
- Pistons: move up and down in cylinders, driven by explosive force
- Crankshaft: converts up-and-down motion into rotary motion
- Camshaft: operates valves, allowing air and fuel into cylinders
-
Common Engine Problems:
- Oil leaks
- Overheating
- Low compression
- Faulty spark plugs
-
Repair Techniques:
- Compression testing
- Leak-down testing
- Cylinder head reconditioning
- Engine block machining
Transmission Systems
-
Manual Transmission:
- Uses gears and clutch to transfer power
- Driver controls gear shifts
-
Automatic Transmission:
- Uses torque converter and planetary gearsets
- Transmission control module (TCM) controls shifts
-
Transmission Components:
- Gears
- Bearings
- Seals
- Clutch packs
-
Common Transmission Problems:
- Slipping or hesitation
- Leaks
- Noise or vibration
- Failure to engage gears
Electronic Fuel Injection
-
EFI Components:
- Fuel injectors
- Fuel pump
- Oxygen sensor
- Engine control module (ECM)
-
How EFI Works:
- ECM calculates air/fuel mixture
- Fuel injectors spray fuel into intake manifold
- Oxygen sensor monitors exhaust gases
-
Benefits of EFI:
- Improved fuel efficiency
- Increased power
- Reduced emissions
- Self-diagnostic capabilities
Brake Systems
-
Brake Components:
- Brake pads
- Rotors
- Calipers
- Brake fluid
-
Brake Types:
- Disc brakes
- Drum brakes
- ABS (anti-lock braking system)
-
Brake Problems:
- Worn or warped rotors
- Spongy brake pedal
- Brake noise or vibration
- Leaks or low brake fluid
Suspension And Steering
-
Suspension Components:
- Springs
- Shock absorbers
- Struts
- Control arms
-
Steering Components:
- Steering gear
- Steering column
- Power steering pump
- Steering linkage
-
Suspension and Steering Problems:
- Worn or loose components
- Noise or vibration
- Uneven tire wear
- Steering wander or pull
