What is a cylinder head or cylinder cover

Marine engine cylinder head is a crucial component of an internal combustion engine used in marine applications. It is typically located at the top of the engine block and forms the upper part of the combustion chamber. The cylinder head seals the cylinders, housing the intake and exhaust valves, fuel injectors (in diesel engines), and spark plugs (in gasoline engines).

Marine Engine Cylinder Head Function

The primary function of the cylinder head cover is to provide a sealed combustion chamber where the fuel-air mixture (or air in the case of a diesel engine) is compressed and ignited, generating power to propel the vessel. It also houses various passages and channels for the intake and exhaust gases to flow in and out of the cylinders.

Marine cylinder heads are typically made from durable materials such as cast iron or aluminum alloy, depending on the specific engine requirements. They are precision-engineered to ensure proper alignment, sealing, and efficient heat transfer.
