produt Introduction:

The cylinder head is one of the core components of the Yanmar diesel engine, located above the cylinder block and sealed with cylinder gaskets to form the combustion chamber together with the cylinder block and piston. It integrates internal components such as intake and exhaust ports, valve mechanisms, and fuel injectors (diesel engines), and is made of cast iron or aluminum alloy materials to balance strength, heat dissipation performance, and lightweight requirements.
