Уплотнение штока клапана головки блока цилиндров Caterpillar 6493031

The Cylinder Head Valve Stem Seal controls the amount of oil that lubricates the valve stem while preventing excess oil from entering the combustion chamber. This seal ensures that the valves operate smoothly without allowing oil to mix with the air-fuel mixture during combustion. Thus, it contributes to engine efficiency by preventing oil consumption, reducing emissions, and maintaining optimal engine performance.Attributes:• Prevents oil from leaking into the combustion chamber.• Withstands high-pressure conditions in the cylinder head.• Prevents oil contamination in the combustion chamber.Applications: The Cylinder Head Valve Stem Seal is located at the top of the cylinder head, around the valve stem, and creates a seal between the valve stem and the valve guide, preventing oil from flowing into the combustion chamber while allowing proper lubrication of the valve stem in the equipment engines.
