Problems solved by technology

Traditional lubricating oil is difficult to lubricate under harsh conditions such as long time, high temperature, and high load, especially the in-situ dynamic self-repair of the surface of the friction pair. Therefore, it is urgent to develop new high-efficiency anti-friction self-repair and life-extending materials and technologies

Abstract

The invention provides internal combustion engine oil for a crawler-type tank and a preparation method of the internal combustion engine oil, and belongs to the technical field of vehicle engine lubricating oil. The internal combustion engine oil disclosed by the invention is prepared from the following raw materials in parts by weight: 80.0 to 92.0 parts of base oil, 0.8 to 1.2 parts of a metal detergent, 2.3 to 5.5 parts of an ashless dispersant, 0.7 to 2.1 parts of zinc alkyl dithiophosphate, 0.1 to 0.54 part of a nanoscale multi-effect abrasive, 0.05 to 0.3 part of alkyl diphenylamine, 2.3 to 5.8 parts of a viscosity index improver and 0.3 to 0.8 part of a pour point depressant. The internal combustion engine oil obtained by the invention is a novel lubricating material prepared on the basis of a nano material, and is an internal combustion engine oil which is outstanding in friction resistance, good in fuel economy, long in oil change period, ultralow in tail gas emission and capable of effectively reducing friction loss of an engine.

Description

technical field [0001] The invention relates to the technical field of engine lubricating oil for vehicles, in particular to an internal combustion engine oil for crawler tanks and a preparation method thereof. Background technique [0002] At this stage, tank engines are mainly developing in the direction of high power, and it is necessary to lay the foundation for the development of high-power engines with the help of high-temperature lubrication technology. For tank engines, during the actual operation of the system, components such as pistons, cylinder liners, and valves will be affected by high temperature and friction, which will inevitably cause damage to the performance of components. In order to promote the efficient operation of the engine, the gap between the cylinder liner and the piston ring should be reduced as much as possible to reduce the impact of frictional resistance on the operating efficiency of the engine. In this case, it is required to have better l...
