摘要

A pH adjusting device for a cylinder liner sliding surface, a cylinder lube oiling device for an internal combustion engine, and an internal combustion engine, which can maintain the pH value of a cylinder sliding surface in an appropriate range regardless of whether sulfur contained in fuel is large or small. (11) for adjusting the supply amount of the pH adjusting agent, a pH adjusting means (14) for adjusting the supply amount of the pH adjusting agent, a pH adjusting means And a control means (20) for controlling the supply amount of the pH adjusting agent (14) so that the pH value of the sliding surface is in an appropriate range, based on the detection result of the pH detecting means (14) The adjusting agent supply amount setting section 23 for setting the adjusting agent supply amount adjusting section 23 and the adjusting agent supply amount adjusting section 23 for controlling the operation of the adjusting agent supply amount adjusting section 11 so as to supply the above- And an adjustment means control section (24).
