It is a structural, thermal, and airflow control component that directly impacts:

  • Combustion Efficiency
  • Engine Power Output
  • Heat Management
  • Long-Term Engine Durability

Every combustion event in a diesel engine depends on how well the cylinder head controls air, fuel, pressure, and temperature.
