Cylinder head for Nissan ZD30

The cylinder head, part number 7701458028, is a component for the Nissan ZD30 diesel engine series. It mounts to the top of the engine block to seal the cylinders and form the combustion chambers. This component contains the intake and exhaust ports, valves, valve seats, and fuel injectors. It also features internal passages for coolant and oil circulation to manage thermal regulation and provide lubrication to the valve train assembly.

This part is compatible with the Nissan ZD30 and Nissan ZD30 LEVAS/WITH engine configurations. It is engineered to maintain the structural integrity of the combustion chamber under operating pressures and temperatures. The design ensures proper compression and prevents the leakage of combustion gases or engine fluids.

A cylinder head functions as the primary closure for the engine cylinders. It provides the necessary housing for the intake and exhaust valves, which regulate the flow of air and fuel into the combustion chamber and the exit of exhaust gases. By maintaining a sealed environment, the cylinder head allows the engine to achieve the compression required for efficient power generation.
