Description

Internal combustion engine oil for crawler-type tank and preparation method thereof
Technical Field
The invention relates to the technical field of vehicle engine lubricating oil, in particular to internal combustion engine oil for a crawler-type tank and a preparation method thereof.
Background
At present, the tank engine is mainly developed towards the direction of high power, and a foundation is laid for the development of the high-power engine under the condition of the help of a high-temperature lubricating technology. For a tank engine, in the actual operation process of the system, components such as a piston, a cylinder sleeve and a valve are influenced by high temperature and friction, and the performance of the components is inevitably damaged. In order to promote the engine to operate efficiently, the pores between the cylinder sleeve and the piston ring should be reduced as much as possible, so as to reduce the influence of the frictional resistance on the operating efficiency of the engine. In this case, a good lubrication condition is required in the system to prevent the occurrence of a failure such as seizure of a member, which may hinder the operation of the engine. When the piston component operates, the temperature of the inner wall of the cylinder sleeve and the temperature of the piston ring at the top dead center are obviously increased, and the high-temperature lubrication technology needs to be adopted for the component, so that the selection and application of a lubricating material are ensured to meet the requirement of a high-temperature environment. For a water cooled engine, the piston member will operate with a top dead center temperature below 240 ℃, but in an air cooled engine this position will experience a greater temperature rise and will be directly proportional to the engine output. When the high-temperature lubricant is used, the oxidation condition, the thermal stability condition and the like under the high-temperature environment need to be fully considered so as to ensure the effective application of the high-temperature lubrication technology.
The traditional lubricating oil is mainly based on common petroleum, can achieve better oxidation characteristic and thermal stability at about 200 ℃, and the lubricating oil can not meet the operation requirement of a modern tank engine system, so that the research of the lubricating oil at the present stage is mainly changed into synthetic lubricating oil. High temperature lubricating oils used in engine systems need to have the following characteristics: firstly, precipitated impurities are not easy to form; secondly, the oxidation stability and the thermal stability can be kept under the high-temperature environment; thirdly, the volatility of the lubricating oil is low; fourthly, the viscosity characteristic is required to be better; fifthly, no corrosion effect is generated on engine components.
Tank as one of important military vehicles, should pay attention to the improvement of anti-deposition performance and oxidation stability when designing its engine, synthetic lubricating oil will be more used for lubricating protection of engine oil. Synthetic oils have excellent low temperature fluidity, outstanding high temperature oxidation resistance and greater wear resistance than mineral oils. The viscosity change of the synthetic lubricating oil is slightly influenced by temperature, and the synthetic lubricating oil can flow under the low-temperature condition and also can keep proper viscosity in the high-temperature environment, so that the abrasion of an engine is reduced, and the service life of the engine is prolonged. In addition, the synthetic lubricating oil has high refining purity, is not easy to be oxidized and decomposed to generate oil sludge and carbon deposit under the continuous high-temperature operation of an engine, and has longer oil change period.
The advance of nanotechnology also brings new research fields to the development of lubricating oil additives. The nano material has interface and surface effect, quantum size effect, small size effect and macroscopic quantum tunneling effect, exists in the form of nano particles or nano films on the friction surface, and has good lubricating property and antifriction property. The novel lubricating material prepared on the basis of the nano material is applied to a friction theory, is one of important research fields of nano science, and can play a role in resisting wear and reducing friction in a mode different from that of the traditional additive. The traditional lubricating oil is difficult to satisfy the lubrication under the harsh conditions of long time, high temperature, high load and the like, and particularly the in-situ dynamic self-repairing of the surface of a friction pair can not be realized, so that the development of novel high-efficiency antifriction self-repairing life-prolonging materials and technologies is urgently needed. The nano material has the special performance, so that the nano material has obvious effects of reducing the friction coefficient of the material, improving the wear resistance of the material and realizing the self-repairing performance of the material. Therefore, the nano material is used for lubricating the surface of a mechanical part, and has potential application prospects in the aspects of improving friction and wear, further prolonging the service life of the mechanical part, improving the maneuvering performance and the like.
