What is the difference between China IV and Jing V, and what does China IV China V mean? Thank you

Beijing V is the emission standard in Beijing, relatively high, the corresponding gasoline standard is also high, if you buy a Beijing V emission car to refuel below, it is not good, easy to break down, because of the harsh requirements, the corresponding Beijing V standard car is generally much more preferential than the national standard

Referring to the emission standard, the Beijing V should be higher than the China IV standard.

The Beijing V standard is a standard customized by Beijing itself, slightly higher than the national IV standard, and there is also a Euro IV standard, and the general car is identified by the Euro IV and the national IV standard, and the Euro IV standard is higher than the national IV standard, that is, the car exhaust emissions meet the national fourth-stage motor vehicle pollutant emission standards (equivalent to the Beijing Phase 5 standard). Abbreviated as "China IV Standard (Beijing V Standard)".

Hello, compared with the "national" emission standard, the emission limit of nitrogen oxides in the "Beijing" standard is reduced by 25%, the index is more stringent, and the emission limit of particulate matter (PM) is specified for the first time. The "Jing" standard sets emission limits for various pollutants, including carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and more. Compared with the "national" standard, the "tightening" of the emission limits of nitrogen oxides in the "Beijing" standard is the most obvious.

The limit of the "national" standard is grams per 1 kilometer driven, while the limit of the "Jing" standard is grams, which is reduced by 25%.

The Beijing V standard is a standard customized by Beijing, which is slightly higher than the national IV standard.

The two concepts of China 5 and China 6 refer to the automobile emission standards issued by the national regulations, and the full name is "Pollutant Emission Limits and Measurement Methods for Light Vehicles". The difference between them is that they are formulated at different stages. The purpose of these standards is to control and reduce the pollutants emitted by vehicles and improve the ambient air quality.

China V will be implemented on January 1, 2017, and the emission standards of China VI will be implemented in two phases: China 6a and China 6b, and from July 1, 2019, the newly registered light vehicles will implement the China 6a emission standards.

"China V (China IV)" is the emission standard of automobiles.

The details are as follows: the "China V" emission standard is equivalent to the Euro V standard, and the latest Euro V standard will be officially implemented in Europe from 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.

In order to cooperate with the implementation of the China V emission standard, Beijing will further improve the quality of oil products and adapt to the China V standard.

In 1999, Beijing implemented the national I standard, and in 2002, the national II standard was implemented, both about 2 years ahead of the national level, and then the national III standard and the national IV standard were also implemented one after another.

In February 2010, Beijing began to study and develop motor vehicles"Country V"Around 2012, Beijing's motor vehicle emission standards will be upgraded from "China IV" to "China V", which was implemented in 2008.

1. National IV refers to: the fourth stage of national motor vehicle pollutant emissions;

2. China V refers to: the fifth stage of national motor vehicle pollutant emissions.

Due to the increasing severity of automobile exhaust pollution, automobile exhaust emission legislation is imperative for countries around the world as early as.

In the sixties and seventies, laws and regulations were established for automobile exhaust emissions, and through strict regulations to promote the progress of automobile emission control technology, with the continuous improvement of automobile emission control technology, it is possible to formulate higher standards.

China IV (China V) of the automobile refers to the oil of China IV or China V that can be used for the car, and the oil used in China IV meets the standards of China IV, and the oil used in country V meets the standards of China V. (iv is country four, v is country five).

The fourth 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 (particulates), 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 the emission of pollutants from vehicles to the specified value below the standard.

Refers to the country in the emissions of automobiles.

Fifth, the sixth national represents the level standard of the total amount of exhaust pollutants emitted by automobiles, the larger the number, the higher the level, and the higher the level, the lower the corresponding engine emissions. Therefore, the emission standards of China VI are higher than those of China V.

Because the main fuel used by automobiles is gasoline, all the pollutants emitted mainly include: carbon dioxide, sulfide, nitrogen oxides, hydrochlorofluorocarbons, non-methane total hydrocarbons, etc., and when these pollutants reach a certain level, they will destroy the ozone layer in the atmosphere, thus causing the greenhouse effect and the formation of acid rain.

In addition, the most lethal injuries are injuries to the human body. Therefore, in order to control the emission of these harmful pollutants, the state has formulated relevant standards for automobile exhaust emissions, the main purpose of which is to promote automobile manufacturers to gradually improve the technology of automobile internal combustion engines to reduce emissions and reduce the pollution of automobile exhaust to the environment.

The things you need to pay attention to when buying a car are as follows:

1. Confirm the purchasing ability

Determine the purchasing power, after buying a car does not affect the overall quality of life of the family, generally according to the average income of the family in the past three years, generally take out 20% of the family for three years, but not more than 10% of the value of the family's fixed assets.

2. Concerns:

The most important thing for a family car is safety, followed by affordability, because the safety of the car carries the life of a family, so safety is the top priority.

3. On-site confirmation:

According to the above two steps, basically determine the several models to buy, and go to the 4S store to confirm on the spot, including test drive, inquiry, loan, repair and maintenance, and other related information.

The main difference is the amount of harmful substances emitted in the fuel exhaust.

To put it simply, the upper limit of sulfur content of China III standard gasoline is 150mg kg, the upper limit of sulfur content of China IV standard gasoline is 50mg kg, and the upper limit of sulfur content of China V standard gasoline is 10mg kg. The rest of the indicators are the same. The main consideration is to gradually reduce the sulfur content in consideration of environmental requirements.

In December 2014, the national IV standard was implemented, and in December 2017, the national V standard was implemented.

At the same time, China IV (China V) is a motor vehicle that meets both emission standards. If your area immediately implements the China V standard, the local 4S shop will also replace the China V standard car. You can check the emission standards from the following points.

First of all, the most obvious way to inquire is on the front windshield of our car, look at the label of the environmental protection mark behind the label, you can easily find it. Another way is to look for it in the various materials of buying a car, and find the page of vehicle consistency or the page at the beginning of the vehicle certificate number, which has a description of the emission standard, but not directly written the country, but a string of characters. Then you can search for the meaning of this string of characters.

China 4 and China 5 refer to emission standards. Except for the logo of country 4 and country 5 pasted on the appearance, there is no difference in others. Since it is an emission standard, it is natural that the technical requirements for the engine and gearbox are higher. That is, less exhaust emissions and more environmentally friendly.

In detail: 1. To put it simply, the upper limit of sulfur content of China III standard gasoline is 150mg kg, the upper limit of sulfur content of China IV standard gasoline is 50mg kg, and the upper limit of sulfur content of China V standard gasoline is 10mg kg. The rest of the indicators are the same. The main consideration is to gradually reduce the sulfur content in consideration of environmental requirements.

In December 2017, the national IV standard was implemented, and in December 2017, the national V standard was implemented. Compared with the China IV emission standard (issued in 2005), the China V standard has greatly tightened the pollutant emission limits.

3. The person in charge of the Science and Technology Standards Department of the Ministry of Environmental Protection said that taking cars as an example: the nitrogen oxides of gasoline vehicles are 25% stricter, and the nitrogen oxides of diesel vehicles are 28% stricter. The China V standard has added a new limit for the number of particulate matter particles, and according to the China V standard, the particulate matter emission limit is 82% stricter.

4. In the national V standard, the durability mileage of automobile pollution control devices has been doubled, from the original 80,000 kilometers to 160,000 kilometers. That is, within 160,000 kilometers, the emission of pollutants from automobiles should meet the requirements of the limit value of this standard.

China IV (China V) This kind of marking means that there are 2 emission standards for the same model at the same time, assuming that you go to buy a car, you can also buy China IV, and you can also buy China V, that is, "subject to the real thing". You get the idea. it.

Differences: Compared with China IV, the standards for the sum of nitrogen oxides (NOx), hydrocarbons and nitrogen oxides (HC+NOX), and particulate matter concentration (PM) have been increased, and the standards for the number of particulate matter particles (PN) and hydrocarbons other than methane (NMHC) have been added to China V.

1. The difference between gasoline vehicles.

In the China V standard, the nitrogen oxide (NOX) emission limit for gasoline vehicles is 25% stricter than that of China IV, and new standards for hydrocarbons other than methane (NMHC) and particulate matter concentration (PM) that are resistant to direct injection gasoline vehicles have been added.

2. The difference between diesel vehicles.

For diesel vehicles, the nitrogen oxide (NOx) emission limit has been tightened by 28%, the sum index of hydrocarbons and nitrogen oxides (HC+NOX) has been tightened by 23%, and the particulate matter concentration (PM) limit for diesel vehicles has been increased by 82%, and the number of new particulate matter particles (PN) is also aimed at diesel vehicles, and the PN standard is only for diesel vehicles. Compared with gasoline vehicles, the China V emission standard obviously has higher requirements for diesel vehicles.

For gasoline vehicles, the requirements for nitrogen oxide emissions have been raised, and the detection of particulate matter concentration of gasoline vehicles directly injected by Yumu Hong in the cylinder has also been added. For diesel vehicles, many indicators have been greatly improved, of which the concentration of particulate matter is 82%, and the target of the national five this increase is more diesel vehicles, reflecting the country's determination to air governance.

1."China V (China IV)" is the emission standard for automobiles.

2.The "China V" emission standard is equivalent to the Euro V standard.

3.Europe has officially implemented the latest EU V standard since September 1, 2009.

4.Beijing plans to implement the China V standard in 2012.

5.Once Beijing fully implements the China V emission standard, it means that vehicles below this emission standard will not be allowed to be sold in Beijing.

6.In order to cooperate with the implementation of China's emission standards, Beijing will further improve the quality of petroleum products to meet China's standards.

7.Beijing implemented the national standard in 1999 and the national standard in 2002.

8.These two standards are about two years ahead of the national standard.

9.Subsequently, national and national standards were implemented one after another.

In February, Beijing began to study and formulate the "National V" emission standards for motor vehicles and the preparation of related oil standards.

In about 2008, Beijing's motor vehicle emission standards will be upgraded from "national" to "national".

China 4 is a unified national emission standard, Beijing 5 is for Beijing's serious air quality pollution, the emission standard is slightly higher than China 4, and foreign Europe 4 is almost the same!

The vehicle exhaust emissions, to meet the national fourth stage of motor vehicle pollutant emission standards (equivalent to the Beijing fifth stage of the standard).

Abbreviated as "China IV Standard (Beijing V Standard)", IV is the meaning of the Roman letter "4", and V is the meaning of "5".

Automotive Environmental Protection China IV is the fourth country.

The full name of the "National IV Standard" is: the fourth stage of the national motor vehicle emission standard, which is equivalent to the European "European standard". Compared with the "National III Standard", the "National IV Standard" is more stringent in the control of motor vehicle emissions, and it is necessary to further reduce the pollutants by 30 50 on the basis of meeting the "National III Standard" to meet the standard."

Beijing V is equivalent to the national 5 standard, which is the emission standard that the vehicle must meet when it is licensed in Beijing, Shanghai and Guangzhou;

China 4 is the national IV standard, which can be achieved in the country except for Beijing, Shanghai, Guangzhou and other places.

The China 4 standard is one level lower than that of Beijing 5 (China 5).
