A Review of Cavitation in the Cooling Fluid of an IC Diesel Engine Due to Forces Generated in the Piston Cylinder Assembly

ABSTRACT

The leaked water directly enters the cylinder for combustion, which brings great difficulty to troubleshooting. After disassembly and inspection, it was found that the exhaust valve seat was corroded and perforated, resulting in water leakage. Therefore, the cavitation of the valve seat directly affects the reliability and service life of the diesel engine. The data indicated that as the water depth decreases and the temperature increases, the weight loss rate increases, reaches a maximum, and then decreases again. Moreover, the weight loss rate increases linearly with increasing suppression pressure. The results indicate that the designer should design the engine with a larger gap between the cylinder liner and the jacket, the cooling liquid temperature value should be outside the extreme corrosion range and prevent high cooling water pressure to avoid severe corrosion.
