What does it mean to be in country 3 and country 6?

What do you mean by China VI standards? It is the meaning of the national sixth-stage motor vehicle pollutant emission standard.

Often referred to as the "most stringent emission standard in history", China VI requires a 50% reduction in carbon monoxide and total hydrocarbons, a 42% reduction in nitrogen oxides and a 33% reduction in particulate matter.

On July 1, 2020, the national VI standard was officially implemented, and some first-tier cities have relatively high requirements for environmental protection, and some have implemented them in advance, such as Shenzhen on January 1, 2019, and Guangdong Province and Shandong Province on July 1, 2019. Tianjin, Hangzhou, Henan, Hebei and other ** documents have also been announced, and the National VI standard will be implemented in 2019.

The difference is that the emission standards are different, China VI is relatively more environmentally friendly, and the emission of harmful substances is lower.

From 1 July 2020, all cars sold and registered must comply with China VI emission A standards. At that time, the National Five car will not be able to be licensed, the National Four.

Emission of vehicles can not be transferred, and the country three.

The car can only be bought as scrap metal.

That is to say, from now on, the China III car will only have a maximum of two and a half years of service life, and it will also be subject to various restrictions. Since the second half of 2017, relevant policies have been introduced across the country to restrict the national three diesel vehicles on the road, and Beijing, Shanghai, Guangzhou, Shenzhen, Hangzhou and other cities have completely banned the national three vehicles from entering the urban area.

It will be implemented in 2018.

Starting from New Year's Day 2018, Shandong, Tianjin and other places will cancel the vehicle operation certificate for the China III heavy-duty diesel trucks that do not meet the emission standards and do not have DPF installed, and the China III vehicles that stop the operation of the DPF without permission.

It has become a common practice to require China III vehicles to be equipped with DPF to meet emission standards.

In order to make the national triple truck meet the emission standards, the installation of DPF is about 20,000 or 30,000, and the most expensive is even as high as 40,000 or 50,000. Many transporters have reported that the actual use of DPF is not ideal for the China III engine, and the DPF on the market lacks effective supervision, and it is very easy to buy fakes.

The above content refers to Phoenix.com-National VI standard is coming, how long can you open your National III?

The standards are different.

China III Standard: Implemented nationwide on July 1, 2007, the engine and exhaust system have been upgraded. The vehicle self-diagnosis system has been added and the three-way catalysis has been upgraded.

Changing the quality of the fuel injection allows the fuel to be fully atomized, so that the fuel is more abundant and the pollution is reduced.

National VI standard: The impact on the car of the national V standard is not very largeYou can still go on the road as usual, but the cars of the second and third countries have depreciated sharply, and in some first-tier cities like Beijing, the cars of the second and third countries are not allowed to enter the city.

Principle. Vehicle emissions refer to harmful gases such as CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulates, soot) emitted from exhaust gases. They are all harmful gases produced by the engine during the combustion work process.

The causes of these harmful gases are different, CO is an intermediate product of incomplete fuel oxidation, when the oxygen is insufficient, CO will be produced, and the large concentration of the mixture and the uneven mixture will increase the CO in the exhaust.

Hello dear, <>

I am glad to answer for you, the three countries, the four countries, the five disturbances, the six car differentiation methods: 1. Motor vehicle registration certificate: The motor vehicle registration certificate, commonly known as the big green book, is marked on it.

2. Environmental protection green mark: three stars are the national three stove type, four stars are the national four, five stars are the fifth of the country, and six stars are the sixth of the country. 3. Year estimate:

Because of the country. 3. Country.

Fourth, the country. Fifth, the sixth and other countries are all listed in the year, optimistic about the model year estimate. Emission standards: The European Union has been in force since the early 90s.

This time, the state clearly stipulates the emission standard of China VI, and the exhaust emission will be more than 50% less than the emission standard of China V. Gasoline vehicles will have 50% lower carbon monoxide, total hydrocarbon and non-methane total hydrocarbon emissions, while nitrogen oxide emissions will be reduced by 42%. <

The three countries, the four countries, the five countries, and the six countries refer to the emission standards of automobiles, because most of China's automotive technology is imported from Europe, so the emission standards are also in accordance with Europe.

3. Europe. Fourth, Euro five, stepped type, reduce pollutant emission standards to carry out.

China III is similar to the Euro III emission standard: in order to reduce the emission standard, the engine and exhaust pipe are upgraded, and the vehicle's "self-diagnosis system" is added, and the emission is monitored to make the emission standard.

China IV is similar to the Euro IV emission standard: that is, China's Stage 4 emission standard, which is 50%-60% lower than China III in terms of emission treatment.

China V is similar to the Euro V emission standard: compared with the China IV standard, nitrogen oxide emissions are reduced by 25%, and emission limits for non-methane hydrocarbons and PM are also added, and the requirements for various harmful air pollution particles and compounds are more stringent.

However, many of the current cars are in accordance with the standards of the national four, the national five is particularly common in some first-tier cities such as Beijing, Shanghai, Nanjing and other places, and the national six will also be implemented in January 2020.

Fourth, China 5 will not be restricted on the road in the short term, but China 1 and Country 2 will basically not be able to go on the road, and China 3 will also be restricted. (Photo by Chen Meilian) 2019

Summary. Dear, I'm glad to answer your <>

The national 3 national 4 national 5 national 6 division standards are as follows, and the national two standards were implemented nationwide on July 1, 2004, and the exhaust system was upgraded. China III Standard: Implemented nationwide on July 1, 2007, the engine and exhaust system have been upgraded. The China IV standard was implemented nationwide on July 1, 2010, and the emission post-treatment system was upgraded, and the oil products were upgraded at the same time.

How to distinguish between 3 countries, 4 countries, 5 countries, and 6 countries.

Dear, I'm glad to answer your <>

The national 3 national 4 national 5 national 6 division standards are as follows, and the national two standards were implemented nationwide on July 1, 2004, and the exhaust system was upgraded. The national three standards were implemented nationwide on July 1, 2007, and the coarse dust upgraded the engine and the rock exhaust gas system. The National IV standard was implemented nationwide on July 1, 2010, and the post-discharge treatment system was upgraded, and the oil grip hole was upgraded at the same time.

Kiss and expand for you. The marks of China 3, 4 and 5 are China II, China IV, China V, and China I, and the countries have introduced different exhaust emission standards at different stages. 1. Country 3, that is, country I, is also called the third stage.

On July 1, 2007, the national three standards were implemented nationwide. 2. Country 4 is also country V, also known as the fourth stage. In 2008, Beijing implemented the "National Fourth Stage Motor Vehicle Pollutant Emission Standard" (referred to as "National 4") for new motor vehicles in the city, and the national 4 standard of automobile fuel began on January 1, 2008.

The National IV standard was implemented nationwide on July 1, 2010.
