I. What is an Engine Cylinder Head?

An engine cylinder head is a core engine component that seals the top of the cylinder block, forming the combustion chamber and providing mounting support for critical parts like valve trains and fuel injectors. As a leading diesel cylinder head manufacturer, we ensure precision machining for optimal sealing, heat dissipation, and airflow efficiency, suitable for turbocharged and naturally aspirated engines—particularly optimized for high-load applications in commercial vehicle and marine engine cylinder heads. Our products pass high/low-temperature cycle tests, complying with ASTM A159 (aluminum alloy) and DIN EN 1561 (cast iron) standards.

IV. Key Components of Diesel Cylinder Heads

(Take heavy-duty commercial diesel cylinder heads as an example)

Combustion Chamber Surface: Withstands 250bar pressure (typical for diesel engines), laser-quenched to HRC50-55 for extreme durability.
Valve Seat Inserts: Inlaid with Stellite alloy, compatible with high-pressure fuel injection (up to 2000bar), with wear resistance exceeding 1,000 hours.
Spiral Coolant Channels: Engineered for high thermal loads, delivering 30% improved heat dissipation and reducing hot-spot temperatures by 50℃.
Bolt Holes: CNC-machined for ±0.02mm positional accuracy, ensuring airtight sealing with the diesel engine block (leakage rate < 0.1%).

VIII. Cylinder Head vs. Cylinder Block: Core Differences

Cylinder Head vs Block - Material/Weight/Process Comparison - Engine Component Selection Guide

Feature	Cylinder Head	Cylinder Block
Function	Seals cylinder, controls airflow/fuel	Supports pistons/crankshaft, forms engine structure
Materials	Aluminum alloy/cast iron/CGI	Gray cast iron/aluminum (lightweight)
Weight	15-150kg (passenger vehicles-marine)	50-500kg (passenger vehicles-heavy machinery)
Key Processes	Valve seat insertion, high-precision surfacing	Cylinder honing, crankshaft bearing boring
Failure Modes	Thermal fatigue cracks, valve seat wear	Cylinder bore deformation, water jacket leaks

While both are core engine components, cylinder heads and blocks differ fundamentally in function and structure. Heads focus on sealing the combustion chamber and supporting critical components, while blocks serve as the engine’s structural skeleton, housing moving parts like pistons and crankshafts. Heads require precision design and surface treatment, while blocks prioritize overall strength and heat dissipation.
