Cylinder head 612650040001

Product Introduction:

The cylinder head, piston top and cylinder wall together form a closed combustion chamber to prevent leakage of high-temperature and high-pressure fuel gas, ensure that the combustion process is carried out in a closed space, and improve the thermal efficiency and power output of the engine. It provides precise installation positions and stable support for intake and exhaust valves, spark plugs (gasoline engines) or injectors (diesel engines), valve guides, valve springs, camshafts and other components to ensure the normal operation of these components and the accuracy of the engine's intake, exhaust, fuel injection and valve timing processes. There are water jackets and oil channels inside. The coolant circulates in the water jacket to take away the large amount of heat generated by the engine combustion and prevent the engine from overheating; the oil channels transport the engine oil to the valve mechanism and other components to achieve lubrication and reduce wear, extending the service life of the components.
