AI Technical Summary
Existing technologies cannot achieve in-situ, automatic, and high-frequency online measurement of the alkalinity of lubricating oil in two-stroke engine cylinders, leading to an increased risk of lubrication failure and an inability to cope with the sudden acid corrosion problems caused by new fuels.
An automatic detection system for lubricating oil return from the cylinder liner of a two-stroke marine engine was designed. The system includes a motion unit, an injection unit, a titration unit, and a draining unit. The system achieves automatic measurement of the alkalinity of the lubricating oil through the movement of the feed tank and acid titration.
It enables in-situ, automatic, and high-frequency online measurement of lubricating oil base value, reducing the risk of lubrication failure and ensuring engine safety and service life.
