Cylinder head for Volvo D13

The cylinder head, part number 85022413, mounts to the top of the engine block to seal the cylinders and form the combustion chamber. This component houses the intake and exhaust valves, valve seats, and guides, while providing mounting points for fuel injectors and glow plugs. Its precise configuration ensures the compression ratios required for engine power and operational efficiency. The component is manufactured by Volvo and is engineered to manage heat dissipation and coolant circulation throughout the upper engine assembly.

This specific part is compatible with Volvo D13 engine configurations. It is designed to withstand the internal pressures and thermal cycles inherent in heavy-duty diesel engine operation. Proper installation ensures the integrity of the combustion chamber and prevents loss of compression or coolant leaks.

In internal combustion engines, the cylinder head acts as the cover for the cylinder block. It creates a closed space where the air-fuel mixture is compressed and ignited. By integrating the valve train and ports for airflow, the cylinder head facilitates the intake of air and the expulsion of exhaust gases, which is fundamental to the four-stroke cycle of the engine.
