AI Technical Summary
In the existing technology, the cooling effect in the upper region of the engine cylinder liner is not good, resulting in high temperature in the upper part of the cylinder bore, which affects the engine cooling effect and stability.
A secondary water inlet is installed in the cylinder body to allow some of the cooling water to enter the upper chamber directly, increasing the water flow velocity. Combined with the EGR cooler assembly, the cooling water circuit design is optimized, and the valve seat is eliminated to increase the size of the EGR cooler.
It improves the cooling effect of various parts of the engine, reduces the temperature of the upper cylinder liner, enhances cooling efficiency, reduces the requirements for fuel and engine oil quality, and lowers energy consumption.
