Cylinder head assembly

 The **cylinder head assembly** is a critical component of an internal combustion engine, mounted atop the engine block to seal the combustion chamber and manage airflow, fuel injection, and exhaust.
-------------------------------------------------------------------------------------------------------------------

### **Key Functions**  
1. **Seals the Combustion Chamber**: Ensures compression and prevents gas leakage.  
2. **Controls Airflow**: Houses intake/exhaust valves and ports.  
3. **Thermal Management**: Integrates coolant passages to dissipate heat.  
4. **Supports Valve Train**: Contains camshaft(s), valves, and related components.  

### **Core Components**  
- **Valves** (Intake/Exhaust)  
- **Camshaft** (OHC/DOHC configurations)  
- **Spark Plug/Injector Ports** (gasoline/diesel engines)  
- **Coolant Passages**  
- **Combustion Chamber Surface**  

### **Materials**  
- **Aluminum Alloy**: Lightweight, common in modern engines.  
- **Cast Iron**: High durability for heavy-duty applications.
