Many people will pay attention to the brand, style, performance and price of the vehicle when buying a car. However, in today's increasingly environmentally friendly world, emission standards have also become one of the important factors that more and more consumers consider. Now, in order to meet users' needs for environmental protection, more car brands have launched engines that meet the national six emission standards. In order to facilitate consumers' identification, the yellow engine logo was born.What is the yellow engine logo? The yellow engine logo is a graphic logo, usually located on the hood of the car or in the upper right corner of the windshield. Unlike other car logos, it has a very obvious yellow background. The specific shape of the logo is round, and there is a shoe with the right foot stepping on the accelerator in the middle. These shoes represent the powerful power and high efficiency of the engine. And the function of this logo is to make it easier for consumers to identify car engines that meet the national six emission standards. What does the yellow engine logo represent? The yellow engine logo is a pollution prevention and control technical measure launched by the national environmental protection department, which aims to help consumers better identify automobile engines that meet the national six emission standards. This logo can not only identify the national six engines, but also help consumers choose cars that are more environmentally friendly, safe and healthy.What is the National Sixth Emission Standard? Before understanding the meaning of the yellow engine logo, let's first understand the national six emission standards. National six emission standards refer to the provisions of the content standards of six harmful substances in automobile exhaust emissions, including carbon monoxide, nitrogen oxides, non-methane total hydrocarbons, PM2.5, PM10 and particle number concentrations, etc. At the same time, the nitrate emission standards and the alkyl preparation institutions are also standardized. Since July 1, 2019, the national six emission standards have been officially implemented. Next, before July 1, 2023, all vehicles in China must meet the national six emission standards, that is, the content of the six pollutants emitted by vehicle exhaust must not exceed the prescribed limit. Why should we use the national six emission standards? Compared with the previous generation of National 5 emission standards, the national six emission standards are stricter.By implementing stricter emission standards, exhaust pollution can be effectively reduced, environmental quality can be improved, and people's health can be improved. In other words, if the car engine is below the national six emission standards, its emissions will cause great damage to the environment and even harm human health. So far, many domestic and foreign car brands have launched engines that meet the national six emission standards, including Mercedes-Benz, BMW, Volkswagen, Toyota, Honda, Ford and other well-known brands. In summary, with people's increasing attention to environmental protection, the role of the yellow engine logo is becoming more and more obvious. By identifying this logo, consumers can easily find cars that meet the national six emission standards. I believe that in the near future, this logo will be used in more car brands and become an important sign to show the degree of environmental protection.
