What is China's national six standards for automobile fuel

The six national diesel standards are to reduce emissions, save energy and improve the quality of oil. The emission data is better than the five national diesel standards, reducing more particulate matter and reducing more emissions of non-methane organic gases and nitrogen oxides.

"National Six" is actually the standard set by the state for automobile exhaust emissions. The emission standards of "National Six" are more than 50% stricter than those of "National Five". From July 1, 2020, all cars sold and registered must meet the National Six A standards.

China's automobile fuel national six standard is the national standard for automobile exhaust emissions, which is more than 50% stricter than national five and will be implemented from July 1, 2020. At present, the National Six Standard is implemented in two stages. The first stage starts from July 1, 2020. All cars sold and registered must meet the National Six A Standard.

The national six standard auto diesel, that is, the oil quality is better, and the emission data is higher than that of the national five standard, which can reduce the emission of more particulate matter and reduce the emission of more non-methane organic gases and nitrogen oxides.

National Five (Vehicle Emission Standards)

First of all, the implementation of the national five standards can effectively reduce the pollution of the atmosphere caused by vehicle exhaust emissions, reduce the concentration of harmful substances in the air, and improve urban air quality. Secondly, the implementation of the five national standards can promote the upgrading and technological innovation of the automobile industry and promote the sustainable development of the automobile industry.

National Five refers to the automobile exhaust emission standards formulated by the environmental protection department, and the national fifth phase of motor vehicle pollutant emission standards, that is, the national fifth standard. The national five emission standards are the exhaust emission standards formulated by the environmental protection department. The larger the number, the stricter the standards, and the relatively lighter the pollution of exhaust emissions.

What does the national five standards for automobiles mean (what does the national five emission standards mean)? The national five standards for automobiles are the national fifth-stage motor vehicle pollutant emission standards and the automobile exhaust emission standards formulated by the environmental protection department. The emission control level is equivalent to the fifth phase emission standards being implemented in Europe.

The exhaust emission standards of the fifth country are stricter than those of the fourth country. On January 1, 2018, the national fifth motor vehicle emission standards were officially implemented nationwide, and new standards and norms were made for the emission content of toxic gases and greenhouse gases in automobiles. At present, the world's automobile emission standards are parallel, divided into Europe, the United States, Japanese standard system.

Recently, the editor often receives from friends about "What is the national five emission standards?" The relevant messages are now explained to you.

Five domestic vehicles meet the "National Five Motor Vehicle Pollutant Emission Standards". In order to implement the relevant laws on environmental protection, reduce and prevent environmental pollution from automobile exhaust, protect the ecological environment, and safeguard human health, and formulate motor vehicle pollutant emission standards.

What is the difference between diesel engine national five and national four

Explosion resistance: diesel (ignition performance) explosion resistance index cetane number low cetane number, the fuel is difficult to ignite, the lagging period is long, and the engine working state is rough; high cetane number, ignition Good performance, short lagging period, uniform combustion, stable engine operation; high cetane number, incomplete local combustion, black smoke.

The fifth country is stricter than the fourth country. In 2017, the nitrogen oxide emissions in the national five emission standards, which began to be fully implemented, were reduced by 25% compared with the national four standards, and new emission restrictions for PM were added. The emission standards for heavy vehicles are stricter.

The nitrogen oxide emission standard is different. The nitrogen oxide emission standard of the national four vehicles is 0.25g/kw. The nitrogen oxide emission standard of the national fifth vehicle is 0.18g/kw. The emission standard of particulate matter concentration is different. The emission standard of particle concentration in China is 0.025g/kw. The emission standard of national five-particulate matter concentration is 0.0045g/kw.

[Pacific Automobile Network] National 4 and National 5 refer to the engine exhaust emission standards. Country 5 will be stricter than Country 4 and emit fewer pollutants, that is, it is more environmentally friendly.

Compared with the National Four Emission Standard, the emission of nitrogen oxides has been reduced by 28%, and the sum of hydrocarbons and nitrogen oxides has been reduced by 23%. For diesel vehicles, the particle concentration has been reduced by 82%, and the newly added particle number detection PN standard only detects diesel vehicles.

Different standards. Compared with the national four standards, the new standard of nitrogen oxide emissions for light vehicles can be reduced by 25%, and nitrogen oxide emissions of heavy vehicles can be reduced by 43%. It can be seen that the biggest difference between the national five and the national four is that it is stricter in the emission of heavy vehicles.

Diesel engine country vi belongs to the national standard

1. In fact, it is not "national vl", but "national VI". National VI" means National VI, and National VI is "National Phase VI Motor Vehicle Pollutant Emission Standard".

2. Represent the fifth country. National V is the national fifth stage motor vehicle pollutant emission standard, referred to as the "national fifth standard", which refers to the standard of compliance with the "Light Vehicle Pollutant Emission Limit and Measurement Method (China Phase 5)".

3. VI represents the national six emission standards. VI is a Roman numeral, and the corresponding Arabic numeral is 6, so country VI is country six. The following numbers: I, II, III, IV, V, VI, VII, VIII, IX, X, XI, XII, representing twelve respectively.

4. The national VI limit is reduced by 15%, the olefin limit is reduced by 25%, and the benzene content limit is reduced by 20%. The upper limit of the diesel polycyclic aromatic hydrocarbon index was reduced by 36%. After the automobile diesel is upgraded from "National Five" to "National Six", the environmental protection performance and use performance of the oil products have been further improved, which can effectively reduce engine carbon accumulation and extend the service life of the engine.

5. The national Vl is the national six emission standard. By the Ministry of Environmental Protection and the State Administration of Quality Inspection respectively on December 23, 2016, 2Released on June 22, 2018, "Light Vehicle Pollutant Emission Limits and Measurement Methods (China Phase 6)" will be implemented from July 1, 2020.

6. This is the national six emission standard, which was implemented on July 1, 2019.
