What Is a Cylinder Head?
The cylinder head sits on the engine block. It seals the combustion chamber. This part houses the components that regulate air, exhaust, and fuel.
Core functions of these engine parts include:
- Sealing combustion gases to maintain the compression ratio.
- Supporting valves to regulate air and intake.
- Housing fuel injectors for precise fuel delivery.
- Managing coolant flow to prevent the engine from overheating.
- Protecting the head gasket to ensure a tight seal.
Replacing a cracked cylinder head that is cracked ensures your operating expenses include less fuel waste and fewer repairs.
