The cylinder head is a cast iron casting, in the internal cavities of which there are intake and exhaust channels closed by valves
Intake channels - with a screw profile.
To ensure heat dissipation, the cylinder head has internal cavities in which the coolant circulates
The cylinder head has insert valve seats made of heat-resistant and wear-resistant alloy.
The struts, rocker shaft with rockers, head cover, intake manifold and cover cap, covering the valve mechanism, are installed on top of the cylinder head.
On the left side (from the fuel pump side), four injectors are installed in the head, and on the right side, the exhaust manifold is attached to the head.
To seal the connector between the head and the cylinder block a gasket made of asbestos-free fabric reinforced with perforated steel sheet is installed.
The holes in the gasket for the cylinder liners are edged with sheet steel.
When assembling a diesel engine at the factory, the cylinder holes of the gasket are additionally edged with fluoroplastic split rings.

Valve rocker arms - steel, swing on an axis mounted on four racks.
Extreme racks - increased rigidity.
The rocker arm axis is hollow and has eight radial holes for supplying oil to the rocker arms.
The movement of the rocker arms along the axis is limited by spacer springs.
The intake and exhaust valves are made of heat-resistant steel.
They move in guide bushings pressed into the cylinder head.
Each valve closes under the action of two springs: outer and inner, which act they blow on the valve through a plate and crackers.
