The lubricating oil of automobile engine is very important for the engine. Without lubricating oil, the engine becomes an ornament. Now Audi service consultant will explain to you the importance of lubricating oil for maintenance!
Cars are like people. If the fuel is the food of the engine, then the lubricating oil should be the blood of the engine. When it comes to maintenance, many car owners will say with a strong voice, "I know, it's just changing the oil and the three filters.". Indeed, "5000km / time oil change for three filters" has been recognized by the vast majority of car owners. But just because of this, the general owners think that as long as the car is maintained in this way at ordinary times, there will be no problem with the car. Once there is a fault, it is the responsibility of the manufacturer or the repair station. But this is often not the case, because each car in the process of running the use of oil, working environment and everyone's driving habits are different, the specific conditions of the vehicle also have great differences. In order to keep the car in good condition and reduce unnecessary customer complaints, we must guide the car owners to carry out comprehensive and systematic maintenance.
Here we take the lubrication system as an example to introduce the importance of comprehensive maintenance. The medium flowing in the lubrication system is lubricating oil, which is composed of base oil and additives. According to its function in the system, it should have the following important functions: lubrication, anti-wear, sealing, noise reduction and cooling. With the development of automobile industry, modern high temperature engine has higher and higher requirements on the function of lubricating oil. At the same time, we often find that after a period of use, a lot of sludge will deposit in the lubrication system, affecting the normal work of the lubrication system, and even serious mechanical failure.
普通润滑油是由基础油和添加剂组成。对于一种润滑油，大家在它的润滑和抗磨方面要求很高，对其他一些功能却比较忽略。其实发动机的高温会使机油氧化而变黑产生油泥，如果润滑油的基础油部分都已经被氧化了，那么其他的功能也就失去了载体，功能也就大部分丢失。这就是为什么以前换油周期很长，而现在一定"5000km／次或3月／次"。因此润滑油的抗 氧 化能力是其他功能的基础。
Ordinary lubricating oil is composed of base oil and additives. For a kind of lubricating oil, people have high requirements on its lubrication and anti-wear, but ignore some other functions. In fact, the high temperature of the engine will make the engine oil black and produce sludge. If the base oil part of the lubricating oil has been oxidized, then other functions will lose the carrier and most of the functions will be lost. This is why the oil change cycle used to be very long, but now it must be "5000km / time or March / time". Therefore, the antioxidant capacity of lubricating oil is the basis of other functions.
在发动机润滑系统中，由于氧化不可避免会出现一些弱酸性物质，时间一长会破坏润滑油的粘度和综合功能。因此需要在润滑油中添加一定的TBN值含量高的添加产品，增加润滑油的抗 氧 化、抗酸化功能，以维持润滑系统的正常功能。这就是汽车添加剂的运用。
In the engine lubrication system, due to oxidation, some weak acid substances will inevitably appear, which will destroy the viscosity and comprehensive function of the lubricating oil over a long period of time. In order to maintain the normal function of the lubrication system, it is necessary to add certain products with high TBN content in the lubricating oil to increase the anti-oxidation and anti acid function of the lubricating oil. This is the use of automotive additives.
