Abstract

The article describes a method for optimizing the consumption of cylinder oil for a diesel engine, uses fuel with a high sulfur content, this is achieved by finding the optimal value for the ACC factor.

Cylinder oil is blended to achieve the correct wash and dispersion level to preserve the piston rings and bushing, and a base number (BN) is needed to neutralize acids generated during combustion. Cylinder oil not only serves to lubricate moving parts, but also serves to control the degree of corrosion on the liner surface. However, to provide the desired lubricating effect, an increase in acid production will require a higher BN level than indicated at the minimum feed rate. This is compensated for by calculating the feed rate based on the ACC factor. Its value is determined for each engine separately and depends on its technical condition and the characteristics of the cylinder oil system. The value of the ACC factor is constant and the feed rate of the cylinder oil when switching to different fuels depends only on the sulfur content in it.

The research has shown that the optimal consumption of cylinder oil for diesel, which uses fuel with a high sulfur content, is achieved by finding the optimal value of the ACC factor. Its value is determined for each engine separately and depends on its technical condition and the characteristics of the cylinder oil system. The ACC factor value is constant and the feed rate of the cylinder oil when switching to different fuels depends only on the sulfur content in it.
