With the improvement of environmental protection requirements of the country, special vehicle exhaust emission standards are also within the scope of requirements. Domestic engines have also been upgraded from State II and State III to State IV. Now, Cheng Li, Hubei, will introduce how you can distinguish between State II and State III. National four engines.
Country 3 and Country 4 apply the standard of Euro 3 and Euro 4 respectively. It can be understood that State 3 = Euro 3, Country 4 = Euro 4, but China’s oil products cannot be compared with Europe. At this stage, China’s requirements for light vehicles have reached 4 or above. Emissions requirements, 3 engines have been eliminated
The so-called "National 3" standard is formulated with reference to Euro III emission standards, and it is much higher than the current "National 2" standard.
The sulfur content of gasoline in the new standard has been reduced from 500ppm to less than 150ppm, and the three kinds of oil products of the National Three and the Second National Gasoline can be mixed. However, the cost price of the National Three Gasoline is increased by approximately RMB 0.145 per country. Will the domestic gasoline price rise after the country uses three gasoline?
The fourth national emission standard is the national fourth-phase vehicle pollutant discharge standard. Automobile emissions mainly include HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), PM (particles), etc. The application of technologies such as active layers of good catalytic converters, secondary air injection, and exhaust gas recirculation systems with cooling devices controls and reduces the standards for emissions of pollutants from cars to below specified values.
