Description

Diesel engine oil composition and preparation method thereof
Technical Field
The invention relates to the technical field of lubricating oil products, in particular to a high-base-number low-SAPS diesel engine oil composition and a preparation method thereof.
Background
With the increasing environmental demands, it is a development trend of modern diesel engines to reduce the emissions of diesel engines and to improve the durability of engines, and in order to meet the emission regulations and to extend the service life of engines, engine manufacturers adopt a series of new technologies in diesel engines, such as improving combustion in engine cylinders, adopting an electrically controlled direct injection technology, improving bearing design, reducing the sulfur content of fuels, and improving the quality of fuels. The most concerned problem of users is how to reduce the running cost of vehicles, i.e. how to economize and scientifically use oil, and to achieve the goal, the engine oil is required to improve the fuel economy and prolong the oil change period to the greatest extent on the premise of ensuring the service life of the engine, and the extension of the oil change period of the diesel engine oil becomes the current research hotspot.
In China, GB 17691-2018, the pollutant emission limit value and the measuring method (the sixth stage in China) of heavy-duty diesel vehicles are implemented in parts of regions first. In order to realize the national VI emission standard, the design of an engine needs to be improved, and the national host plants mostly adopt the technical route of low EGR + DOC + DPF + SCR to develop the national VI engine at present. Because of the post-treatment technologies such as DPF, SCR, etc., diesel engine oils are required to have low sulfur content (not more than 0.4%), phosphorus content (not more than 0.12%), and sulfated ash content (not more than 1.0%).
The base number is an important indicator of diesel engine oils and is mainly provided by basic additives (detergents). The main function of the basic additive is to neutralize acidic substances produced by combustion and oxidation in the engine. It is believed that the higher the base number, the greater the ability of the engine oil to neutralize acidic species. The base number of commercially available CJ-4 and CK-4 diesel engine oils is generally 10.0mgKOH/g or less, and the base number decreases as the engine oil is oxidized and contaminated with use. The rate of decrease is related to the amount of acidic material contained in the engine oil. By oil detection, the base number of the engine oil can be measured, and the service life of the engine oil can be known by tracking the base number. Once a 5. sup. th base number drop is found, it is considered to be low and the engine oil is ready to be changed.
In the sixth stage of China, because post-treatment technologies such as DPF, SCR, etc. are adopted, diesel engine oils are required to have low sulfur content (not more than 0.4%), phosphorus content (not more than 0.12%), and sulfated ash (not more than 1.0%). The base number of the engine oil is mainly provided by a detergent, and increasing the content of the detergent increases the base number of an oil product, but also increases an index of sulfated ash, so that the ash content of the commercially available CJ-4 and CK-4 diesel engine oil is below 1.0%, and the base number is also below 10.0 mgKOH/g.
Patent US20070027045 reports a low phosphorus, low sulphur, low ash diesel engine oil composition, the sulphate ash content of which is 1.07%. Patent CN108003972 reports a diesel engine oil composition having a phosphorus content not exceeding 0.12%, a sulphur content not exceeding 0.4%, and a sulphated ash content not exceeding 1.0%.
With the improvement of product quality in the market, a long oil change period is provided, so that the diesel engine oil with high base number and low ash content can be well applied in six stages of China.
