The Ministry of Environmental Protection recently released the National Environmental Protection Standards "Control Standards for Vehicle Gasoline Hazardous Substances (Fourth and Fifth Phases)" and "Control Standards for Vehicle Diesel Hazardous Substances (Fourth and Fifth Phases)". These two standards will be It will be implemented on May 1 this year. The standard has a clear requirement for the quality of vehicle gasoline and vehicle diesel fuel that the national fourth and fifth stage emission standards correspond to.

According to reports, the preparation of these two standards relied on the “Study on control standards and control pathways for hazardous substances in motor vehicles and diesel vehicles for the fifth phase of the country” by the Ministry of Environmental Protection's special research project. Compared with the product quality standards, these two standards stipulated that the The requirements for hazardous substances and environmental protection indicators for vehicle gasoline and vehicle diesel fuel required by the five-phase automobile emission standards increase the detergency requirements and corresponding detection methods for vehicle gasoline and vehicle diesel fuel. The new standard subregionally regulates the vapor pressure of gasoline for motor vehicles to reduce the emission of volatile pollutants more scientifically and reasonably.

Experts pointed out that the release of the "Control Standards for Vehicles with Harmful Substances in Harmful Gases (Fourth and Fifth Phases)" and "Control Standards for Automotive Diesel Fuel Hazardous Substances (Fourth and Fifth Phases)" will be the fourth and fifth phase of national vehicle emissions. The implementation of standards will promote the environmental management of fuel quality for vehicles and play an important role. At the same time, it will play a positive role in guiding petrochemical enterprises to organize production and promote the supply of automotive oil products that meet more stringent emission standards.
