Method of defining the operating parameters for the piston-cyclinder liner unit in the low-speed compression-ignition two-stroke engines

摘要

A method of defining the operating parameters for the piston-cylinder liner unit in the low-speed compression-ignition two-stroke engines comprising the following steps: removing all insulating elements from the cylinder liners, measuring the temperature and relative humidity of the supercharging air before the turbosupercharger as well as the supercharging air pressure after the cooler and barometric pressure in the engine room, determining the temperature of the dew-point of the supercharging air after the cooler, determining the minimal temperature of the air cooling water in the inlet in order that the temperature of the charging air is maintained slightly higher than the dew-point, continual monitoring the temperature of the cylinder liner bearing surface, adjusting the temperature of the cylinder cooling water on the inlet, so that the temperature of the cylinder liner bearing surface is kept lower than the temperature of the cylinder oil flash point.
