A new type of cylinder liner cooling water cavity
By setting up cooling water channels on the outside of the diesel engine cylinder liners and using structures such as inclined guide plates and filters, the problems of cooling water scouring, corrosion, and leakage of the engine block water channels are solved, achieving efficient cooling and reducing the risk of failure.

AI Technical Summary
In existing diesel engine cylinder liner cooling structures, the scouring of engine block water passages by cooling water leads to corrosion and the seepage of cooling water into the lubricating oil, causing quality incidents.
A novel cylinder liner cooling water chamber is designed, with the cooling water flow channel located between the cooling water jacket and the cylinder liner. It employs inclined guide plates, filters, heat dissipation fins, reinforcing ribs, and multiple sealing structures to prevent high-speed water flow from scouring the engine water channels and to prevent cooling water leakage.
It effectively avoids the scouring and corrosion of the machine's water channels, prevents cooling water from seeping into the machine and contaminating the lubricating oil, improves cooling efficiency, and reduces the risk of failure.
