- The cylinder head contains intake and exhaust valves
- Controls airflow into and out of the combustion chamber
4. Camshaft(s)
- Operates the opening and closing of valves
- Located in the cylinder head (overhead camshaft) or within the engine block (pushrod engines)
5. Timing Belt or Chain
- Synchronizes the rotation of the crankshaft and camshaft(s)
- Critical for proper valve timing
6. Fuel Injection System
- Injects fuel into the combustion chamber
- Includes fuel injectors, fuel pump, and fuel rail
7. Intake and Exhaust Manifolds
- Direct air into the cylinders and expel exhaust gases
- Designed for optimal airflow and performance
8. Cooling System Components
- Radiator, water pump, thermostat, coolant passages
- Keeps engine temperature within optimal range
9. Lubrication System
- Oil pump, oil filter, oil passages
- Reduces friction and wear on engine parts
10. Sensors and Electrical Components
- Oxygen sensors, mass airflow sensors, throttle position sensors
- Connect to the engine control unit (ECU) for efficient operation
