AI Technical Summary
It is difficult to design a plunger engine oil composition suitable for low sulfur distillate fuels, especially in terms of oxidation stability, viscosity increase control and cleaning performance. Traditional additive technologies cannot effectively adapt to the environment of low sulfur marine distillate fuels.
A lubricating oil composition comprising a primary amount of a Class I base oil, a detergent composition and a non-permaintenance vulcanized alkylphenol detergent is employed. The detergent composition includes medium-basic and high-basic detergents, the non-basic vulcanized alkylphenol detergent prepared by a specific preparation method substantially free of polyol accelerator oxidation products.
The lubricating oil composition exhibits optimal performance in terms of oxidation stability, viscosity increase control and high temperature cleanliness, and can effectively adapt to the environment of low sulfur distillate fuels and meet the lubrication needs of the plunger engine.
