[0025] Each component of the raw material was prepared into each formulation for experimentation, and the composition of each formulation is shown in Table 1. The above mixture was heated and stirred at 60° C. for 1 hour until completely homogeneous.
[0026] The water washing resistance test (GJB 6028) was used to investigate the water washing resistance of the oil. The lower the decrease rate of alkali number and sulfate ash content, the better the water washing resistance of the oil.
[0027] The specific results of each formula test are shown in Table 2.

Description
technical field [0001] The invention relates to a marine diesel engine oil composition and its application. Background technique [0002] With the increase in size and power of ships, the high sulfur and low quality of main engine fuel and the use of advanced marine engines, at the same time, in order to meet the legislation and index requirements of safety, reliability, economy, environmental protection and energy saving of ships, marine engines The performance of lubricating oil has put forward higher and more stringent requirements. [0003] In order to meet the normal operation requirements of marine diesel engines, marine diesel engine oils need to have good quiet dispersibility, anti-oxidation, anti-wear properties, acid neutralization and thermal oxidation stability. At the same time, because marine diesel engine oil is used in an environment that is easy to contact with water for a long time, marine diesel engine oil also needs to have good water washing resistance....
