Since the emission of China VI, many car owners have wondered about the difference between China V and China VI, why the maintenance of China VI engines is more complicated than in the past. In fact, the biggest difference between the two emissions is that the National VI engine uses a three-way catalyst, so its engine performance is better than that of the National V engine, but the power data of the two models is not much different. According to the title, let's take a look at the difference between the two engines and how to correctly select a unified titanium combined oil for the engine in maintenance.
First of all, the difference between the engines of the two models is in terms of software. Some car companies will optimize the treatment through the structure of the combustion chamber, and then increase the injection pressure, the purpose of which is to make the atomization effect of gasoline better. The National VI engine uses a three-way catalytic converter, which has the advantage of enhancing the exhaust gas processing capacity, improving the overall performance of the vehicle, and some models will also install GPF particle traps to reduce carbon emissions. This is also one of the reasons why two different models choose different unified titanium combined energy engine oils.
Secondly, in the China V model, the requirements for emission standards are the restrictions on substances such as sodium hydroxide, suspended particles, monooxides and nitrogen oxides. Among them, nitrogen oxide emissions must be reduced to 25%, and this provision of the China V model is mainly to reduce the pollution of the atmosphere caused by exhaust emissions. The emission standards of China VI models are 50% lower than those of China V models, of which nitrogen oxide emissions are less than 42%, which is why the emission requirements of China VI models are strict.
Therefore, we would recommend the use of different uniform titanium oils for engine maintenance of two models with different emissions. For example, if the owner buys the latest National VI engine model, then we will recommend the use of the series of 9 series PLUS, this oil has now passed the German Volkswagen original certification and Porsche certification, suitable for all kinds of requirements to use the new engine 0W-20. If it is a national five model, then it is more appropriate to choose the 7 series, and the current red oil viscosity grade of the product is also divided into 5W-30/5W-40, of which 5W-30 is a low ash formula. Of course, these two viscosity grades of products are installed in the national six standard production of environmentally friendly oil, according to the engine maintenance requirements to make a reasonable choice.
In addition, in addition to the impact of the engine on emissions between the China V model and the China VI model, it also includes fuel, which is also a key factor affecting the level of emissions. Because the National VI model not only has a technical upgrade to the engine, but also the quality of the fuel is much stricter than any previous model, it is precisely because of this that it can meet the requirements of the emission standards and emit qualified exhaust gases.
In summary, under the strict National VI standards, whether you are driving China V or China VI, if you want to meet the emission requirements, then whether it is in maintenance or fuel, it must be standardized and rigorous.
