Abstract

The invention discloses an energy-saving long-service-life low-ash-content diesel engine oil composition. The composition comprises the following components in percentage by weight: 17-21.4% of a composite additive; 4.5%-12% of a viscosity index improver; 0.2%-0.5% of an antioxidant; 0.3%-0.5% of a pour point depressant; base oil: and the balance, wherein the composite additive contains salicylate. The energy-saving long-service-life low-ash-content diesel engine oil composition provided by the invention has lower ash content, has excellent base number retentivity, high-temperature oxidation resistance and wear resistance while protecting the DPF-containing aftertreatment device of the engine, can provide excellent protection for the engine meeting national VI emission, has the longer service life, and can effectively prolong the oil change period. In addition, on the premise that the durability of the engine is protected, excellent fuel economy performance can be provided, and the comprehensive fuel economy of the heavy commercial vehicle can be improved.

Description

technical field [0001] The invention relates to a diesel engine oil composition, in particular to an energy-saving long-life and low-ash diesel engine oil composition. Background technique [0002] Energy saving, environmental protection and extended oil change intervals have become the three major driving forces to promote the replacement of internal combustion engine oil. As countries pay more and more attention to environmental issues, more stringent exhaust emission standards have been introduced one after another. On June 22, 2018, my country officially issued the "Heavy-duty Diesel Vehicle Pollutant Emission Limits and Measurement Methods (China Phase VI)" emission standard, which was officially implemented on July 1, 2019. In order to meet the requirements of China VI emission standards, OEM manufacturers continue to upgrade engines, such as the use of exhaust gas recirculation (EGR), electronically controlled common rail and other technologies, and at the same time ...
