  • Water Temperature of Water-cooled Diesel Engine Is Too …

    Mar 05, 2019 · Mar. 05, 2019. Excessive water temperature is one of the most common failures of diesel water-cooled type. Due to the different thermal expansion coefficients of the cylinder sleeve and piston friction pair material, the high temperature will make the gap smaller, the lubrication condition will deteriorate, and the cylinder and piston ring will be stuck for a long time.
