What is an engine antiwear agent? Engine antiwear agent is a kind of engine oil additive, which has stronger adhesion than engine oil and is more heat-resistant and corrosion-resistant. It can be said that a protective film was pasted on the inner wall of the cylinder, which enhanced the lubrication effect, repaired the scratches on the inner wall of the cylinder, made the rough surface smooth, ensured the normal high-speed operation of the engine, and played a role in maintenance.
The antiwear agent also has a cleaning function, which can dissolve the excess fuel, impurities and carbon deposits in the cylinder, so that the high temperature and high pressure oil and gas in the cylinder can be fully burned without other impurities.
Some car owners may ask, since it is an additive, it can be added or not! In theory, but in practice? When we go to the 4S shop for maintenance, the maintenance master will recommend the use of engine antiwear agent, curing agent and protective agent, so do you want to add it or not?
Let's take a look at the following Timken wear test:
This is a simulated anti-wear test of automobile engine! The weight on the left is 1 kg each, and the lever force of the mechanical arm is 1:20, that is, releasing the weight of 1 kg is equivalent to giving the engine 20 kg of force. We use "engine oil" and "engine oil plus anti-wear agent" to PK, and see under which circumstances we can bear more weight.
As a result, the oil without anti-wear agent is stuck when it is added to the third weight! After adding anti-wear agent, the engine oil can run all the time when it is added to 20 weights! This fully shows that engine oil+antiwear agent = stronger engine protection, and the addition of engine antiwear agent is necessary.
Of course, there are many kinds of engine antiwear agents, such as chemical synthesis, ceramic materials, graphene materials and so on. Brands are uneven, so learn to choose.
In a word, automobile maintenance can not be ignored, especially the maintenance of automobile engines. Anti-wear protective agent for automobile engine is equivalent to the nutrition of engine, which can protect the health of engine to a certain extent and prolong the service life of engine.
The petrochemical additive manufacturers in Europe and America have a history of 100 years. Volkswagen and other European and American models drive in Europe and America without burning engine oil. Some people will say that fuel is better than domestic fuel. Indeed, we must admit that the desulfurization technology of domestic fuel has not reached such a high level. However, is the difference between hundreds of thousands of European and American cars that have not been overhauled and the domestic market that has been overhauled for 100 thousand kilometers really a fuel problem? Actually, it's not. European and American models are equipped with various additives when they are used in Europe and America. We often say that all kinds of high-grade engine oil are refined from base oil and added with a certain proportion of additives to achieve various special effects of engine oil. Engine oil exhaustion mainly refers to the consumption of additives in engine oil, which leads to the need to change engine oil. Therefore, all kinds of products to improve engine oil performance are smooth in principle, but under the logic of smoothness, there are very few effective products.
The logic of antiwear agent is as follows, containing so-called antiwear oil.
Engine wear-resistant products on the market, including advanced synthetic engine oil, mainly aim to provide protection for engine parts to reduce wear during working. When the wear is reduced, the engine noise and cold start noise that we often say, as well as the wear of 3 kilometers before cold start, will be much reduced. But how many people know what is the best wear-resistant material? The answer is graphene. Note that it is not graphite powder. Graphite powder also has anti-wear effect, but the anti-wear time is relatively short, which can not achieve lasting effect. So what is the current price of graphene from 2065438 to February 2008? 3000 yuan/gram. This is calculated in grams, and the price is not Jin or kg.
Then let's think about it. General vehicle maintenance is 4-6L oil at a time. According to the calculation of 3000 yuan for one gram of graphene, how much is our engine oil? A few hundred yuan of engine oil, the base oil of good engine oil is very good, but the main function of engine oil is lubrication. No engine oil says it is wear-resistant, so where can we get better ride comfort, noise control and cold start protection without wear? In synthetic engine oil, additives should be added to realize various functions. According to the cost, we can also calculate the probability of adding graphene, an advanced material. Just like an old Chinese medicine ointment, there is no Chinese medicine in it, only western medicine.
Let's first popularize the characteristics of graphene: graphene is the thinnest and strongest material found so far. Thin because graphene is a two-dimensional crystal composed of carbon atoms, with a thickness of only one atom. Although it is extremely thin, it is so dense that even helium with the smallest atomic size cannot penetrate it. Mechanically, graphene is the strongest and tallest substance known to mankind. 1g graphene is more than Huang Jingui.
At present, the best antiwear agent is graphene, and Siyoupu's antiwear agent cannot be sold on a large scale because of the relationship between production capacity and cost. Its main components are the synthesis of a small amount of graphene and high-grade base oil. Speaking of base oil, it is the most basic raw material for many brands of engine oil. Therefore, Siyoupu's anti-wear products can be mixed with any brand of engine oil to protect the engine from chemical reaction. In order to realize the protective and comfortable experience of the engine, reduce the fuel consumption caused by wear to a great extent, and achieve the purpose of smooth gear shifting, it is very suitable and wise to choose this product.
