Abstract

The invention relates to a lubricating oil composition for diesel engines, belonging to the technical field of addition of lubricating oil. The invention aims to provide a long-oil-change-period low-emission lubricating oil composition for diesel engines. In order to solve the technical problem, the technical scheme is as follows: the lubricating oil composition for diesel engines comprises the following components in percentage by weight: 0.4-2.5% of hindered phenol antioxidant, 0.9-2.0% of amine antioxidant, 0.8-3.0% of antioxygen anti-friction multifunctional additive, 0.2-1.5% of metal anti-friction agent, 4.0-15.0% of complexing agent and the balance of base oil. The lubricating oil composition for diesel engines has the advantages of long oil change period, low volatility and excellent stability, and can be widely used in the field of diesel engine lubrication.

Description

technical field [0001] The invention relates to a lubricating oil composition for a diesel engine, in particular to a lubricating oil composition for a long oil change period and low emission diesel engine, and belongs to the technical field of lubricating oil additives. Background technique [0002] Energy saving, environmental protection emission and extended oil change period are the three major driving forces to promote the rapid development of the automobile industry and internal combustion engine oil. The application of new technologies in automobile engines puts forward more and more stringent requirements for lubricating oil formulations: (1) The improvement of environmental protection requirements , The enhancement of energy conservation awareness requires high-quality low-sulfur, low-ash lubricating oil products. (2) The increasing demand for energy-saving engine oil has prompted the development of lubricating oil in the direction of high viscosity index and low vi...
