What does the emission standard of the car mean

China's emission standards are divided into: country.

5. China VI, as of December 31, 2018, the national 5 emission standard for light-duty gasoline vehicles has been implemented.

The China 6 emission standard is implemented in two stages:

In the first phase, from July 1, 2020, all cars sold and registered must comply with China VIA standards;

In the second phase, from July 1, 2023, all cars sold and registered must comply with China VIB standards; Some cities will implement China VI emission standards for light vehicles as of January 1, 2019.

Implementation of China VI.

Not only do automakers need to optimize engines more precisely as soon as possible, but they also need to accelerate the optimization and modification of a series of components such as three-way catalysis. Not only that, but this is also a challenge for major oil companies, which need them to improve their production standards and refine and manufacture higher quality fuels, so as to cooperate with car companies to meet the China VI standard.

In fact, when it comes to oil, one topic that cannot be avoided is the difference between oil products at home and abroad. It has to be admitted that the difference in oil products is the result of multiple factors such as different standards and processes.

The oil quality of European countries is indeed higher than that of domestic fuel, and the same number of gasoline, the oil of EU countries is obviously smaller than the domestic taste, and it is not so pungent, and the color is much clearer, not only the power is better, but also the harmful substances it contains are relatively few.

1. The national IV emission standard is the fourth stage of the national motor vehicle pollutant emission standard, the main pollutants emitted by automobiles are HC (hydrocarbons), NOx (nitrogen oxygenate), CO (carbon monoxide), PM (particles), etc., through the application of better catalytic converter active layer, secondary air injection and exhaust gas recirculation system with cooling device, etc., to control and reduce automobile emission pollutants to the standard below the specified value.

2. The domestic automobile emission standards mainly refer to European standards. China III, China IV emission standards pollutant emission limits are exactly the same as Euro III and Euro IV standards, and we can see from the above ** that the China IV standard is more stringent than the China III requirements for NOx and PM.

3. There are also two main upgrade schemes in the China IV era, one is to use selective catalytic reduction (SCR) technology to treat nitrogen oxides in the exhaust gas by using urea solution; There is also an EGR (Exhaust Gas Recirculation) technology that treats the particles produced by combustion by means of a particulate trap (DPF) or a particulate catalytic converter (DOC).

4. The two technical routes of egr and SCR have been adopted in Europe and the United States and other countries, and they can achieve Euro IV and Euro V emission standards, so what is the difference between them? Here's a brief introduction.

At present, the China V emission standard is implemented. The emission standards of China V were officially implemented on January 1, 2017, and the emission standards of China V are relatively more stringent than those of China IV, the new standard can reduce nitrogen oxide emissions from light vehicles by 25%, and nitrogen oxide emissions from heavy vehicles can be reduced by 43%, and the emission control level of domestic China V standards is equivalent to the fifth phase of emission standards being implemented in Europe. The national standard for automobile emissions is different from the European standard, and the national standard is a national standard formulated according to the specific situation of our country, so you need to pay attention when buying a car, especially when buying a parallel imported car, you must understand the emission standards in detail, so as to avoid not being able to list the car after buying it.

Attached: How to view automobile emission standards:

1. Environmental protection label:

This is the most simple and direct way to check the car emission standards, there are obvious marks behind the environmental protection signs, which say that it is the emission standards of the country, but now there is no environmental protection label.

2. Motor vehicle environmental protection network:

Log in to the Motor Vehicle Exhaust Pollution Supervision and Management Center**, enter the model model, note that it is not the frame number, and the engine model can find the emission standard of the car.

3. Vehicle management office inquiry:

This is the most accurate way to check the emission standards of the car, with the original or copy of the motor vehicle registration certificate to the vehicle management office to inquire, the relevant staff will tell you the emission standards of the car.

So that the annotation is still a lot of e

Enter the motor vehicle environmental protection network, enter the fuzzy conditions (vehicle model) in the input box of the web page, and then enter the correct verification code, and click on the query to find the relevant information of the car, including emission standards.

Generally, there will be a nameplate under the B-pillar of the co-pilot. There may be relevant labels in the lower left corner of the front windshield, on the driver's door pillar, on the left side of the dashboard, in the engine compartment, on the self-adhesive of the test door, in the door frame base, in the glove box and other places.

Vehicle Emissions Considerations.

If the car is driven on the road without passing the inspection or without obtaining the inspection mark, it shall be punished in accordance with the law. Where the emission of air pollutants from motor vehicles in use exceeds the standard, maintenance shall be carried out; If the air pollutant emissions still do not meet the national emission standards for motor vehicles in use after maintenance or the use of pollution control technology, they shall be forcibly scrapped.

Motor vehicle exhaust emissions do not meet the standard, there are many reasons for motor vehicle exhaust exceedance, it is recommended that you go to a professional motor vehicle inspection and inspection agency, do a test for your car, and listen to the advice of professionals.

European standards are implemented by the emission regulations of the Economic Commission for Europe (ECE) and the emission directives of the European Community (EEC), which is the European Union (EU). Emission regulations are voluntarily endorsed by ECE participating countries, and emission directives are mandatory by EEC or EU participating countries. The European regulations (directives) of automobile emissions standards have been implemented in several stages before 1992, and Europe has been implementing the European type certification emission limits since 1992.

The national standard for vehicle emissions is not the same as the European standard. The national standard is a national standard formulated according to the specific situation of our country. The European standard is the standard used by the members of the European Community. The European standard is slightly higher than the national standard.

The "China V" emission standard is equivalent to the Euro V standard, and the latest Euro V standard has been officially implemented in Europe since September 1, 2009. In 2012, Beijing plans to implement the China V standard, and once Beijing fully implements the China V emission standard, it means that models that do not meet this emission standard will not be allowed to enter Beijing for sale. Previously, in order to control motor vehicle pollution, Beijing has been implementing relevant national standards in advance.

In order to cooperate with the implementation of the China V emission standard, Beijing will further improve the quality of oil products to adapt to the China V standard. China's first batch of buses with European V emissions will be put into the Beijing public >

With the continuous development of society, cars have become an indispensable part of people's lives. However, the impact of vehicle emissions on the environment and human health is also becoming increasingly apparent. In order to protect the environment and human health, China will implement the "strictest in history" China VIB emission standards.

So, what impact does this criterion have on our car purchase?

First of all, let's understand what is the China VIB emission standard. China VIB emission standards refer to stricter restrictions on pollutants such as nitrogen oxides, hydrocarbons, and particulate matter emitted by vehicles on the basis of national environmental protection standards. Compared with the China V standard, the China VIB standard is more restrictive and has higher emission requirements for vehicles.

So, what impact does this criterion have on our car purchase?

First of all, the implementation of China VIB will promote the upgrading and innovation of automotive technology. In order to meet higher emission standards, automakers must continuously improve their vehicle technology and introduce more environmentally friendly and energy-efficient automotive products. This will promote the development of the automotive industry and improve the quality and competitiveness of automotive products.

Secondly, the implementation of the National VIB standard will have a certain impact on the automotive industry. In order to meet higher emission standards, automakers must adopt more advanced technologies and higher-quality components, which will lead to increased manufacturing costs for vehicles. As a result, there may also be an increase in automobiles**.

However, as technology develops and costs fall, automobiles** are likely to gradually decrease.

Finally, the implementation of China VIB will have a positive impact on the environment and human health. The implementation of China VIB will significantly reduce the impact of vehicle emissions on the environment and human health, improve urban air quality, reduce the risk of air pollution, and protect human health. This is the most important significance of the China VIB standard.

In short, the impact of the implementation of China VIB emission standards on our car purchase is multifaceted. It will promote the upgrading and innovation of automotive technology, which will have a certain impact on automobiles, but most importantly have a positive impact on the environment and human health. Therefore, we should support the implementation of China VIB standards, actively participate in environmental protection actions, and jointly protect our environment and health.

The implementation of China VIB is not a simple task, it requires the joint efforts and support of each of us. We should actively participate in environmental protection actions through our own actions, reduce the impact of vehicle emissions on the environment, and jointly create a better living environment.

Vehicle emission standards are developed to control the emission of pollutants from automobiles.

The emission standards of automobiles are mainly to reduce the emission of harmful gases, inhibit the generation of harmful gases, and also prompt automobile manufacturers to improve their products. With the continuous improvement of living standards, the number of cars is also increasing, and the emission standards of automobiles will be refined and tightened with the deterioration of the environment.

China's vehicle emission standards are modelled on European vehicle emission standards. Common vehicle emission standards are China 5, China 4, China 3, Europe 5, Europe 4, and Europe 3.

Automobile exhaust contains a lot of harmful gases, which not only affect the atmospheric environment, but more importantly, affect people's health. Automobile exhaust contains harmful gases such as CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), PM (particulate matter, soot), etc.

These harmful gases are produced during engine combustion, where carbon monoxide is an intermediate product of incomplete oxidation of fuel. Carbon monoxide is produced when oxygen is insufficient, and the concentration of the mixture in the engine increases, and the unevenness of the mixture leads to an increase in carbon monoxide.

Hydrocarbons are unburned substances in fuel oil, and some of the fuel is discharged without combustion due to uneven gas mixture, cold combustion chamber walls, etc. Nitrogen oxides are a substance produced during fuel combustion, and particulate matter is a substance produced by the lack of oxygen during fuel combustion.

The most common vehicles on the road are state, state, and state-leased vehicles. After the official implementation of the national standard, the vehicles with the national emission standard will be forcibly eliminated. The national emission standard refers to the national sixth-stage motor vehicle pollutant emission standard.

Compared with the China V emission standard, the China VI emission standard will strictly control pollutant emissions, such as reducing carbon monoxide emissions by 50%, limiting total hydrocarbon and non-methane total hydrocarbon emissions by 50%, and reducing nitrogen oxide emissions by 42%.

Generally speaking, as the number of car socks increases, the emission standards of cars will become more and more stringent.

Millions of car purchase subsidies.
