Abstract

The invention relates to anti-wear energy-saving engine lubricating oil, which comprises basic oil and an additive serving as raw materials, wherein the basic oil is hydrogenated isodewaxed III type basic oil; the additive is an anti-wear agent MODDP, namely, molybdenum dialkyldithiophosphate. The complex system has a good synergistic effect, so that the wear reduction, anti-wear, carbon deposit reduction, oil sludge dispersion and anti-wear energy-saving effects become more remarkable. Under the condition of high temperature and high pressure, MODDP is decomposed to form an MoS2 protective film, and meanwhile a novel metal produced by friction undergoes a friction chemical reaction to generate FePO4 and FeS reaction films, so that unique 'anti-wear, repair, energy-saving and environmental protection' effects are achieved on an engine, remarkable repairing and maintaining functions are realized, and the service lives of equipment such as engines are prolonged; equipment such as engines is protected, and the worn inner cylinder wall of equipment can be repaired automatically; a cylinder body can be kept clean, continuous protection is provided, and the service life is prolonged.

Description

Technical field: [0001] The invention relates to a lubricating oil, in particular to an anti-wear and energy-saving engine lubricating oil. [0002] Background technique: [0003] "Lubrication" is a traditional equipment management technology. With the development of modern equipment to large-scale, precision and automation, there are higher requirements for the traditional technology of "lubrication", which is mainly reflected in how to adopt advanced lubrication technology and deployment methods , Reduce abnormal wear of equipment, reduce spare parts consumption, reduce energy loss, and ensure safe operation of equipment. The existing large-scale heavy-duty vehicles have a large operating load, high summer temperature, and large wear and tear, which have a great impact on the life of the vehicle. Therefore, a lubricant is provided to solve the problem that the heavy-duty vehicles can be better under the environment of high temperature and high load. Friction prolongs t...
