The difference between the car country V and the country LV is there

Country V and China IV refer to emission standards. The higher the better, and the higher the greener.

Compared with the China IV emission standard (issued in 2005), the China V standard has greatly tightened the pollutant emission limits. 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.

In the China V standard, the durability mileage of automobile pollution control devices has been doubled, from 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.

The differences between national LV and national V are as follows:

1. The time of standard implementation is different.

The implementation of the China IV standard started on December 30, 2005.

The implementation of the China V standard started on September 17, 2013.

2. The emission standards for automobiles are different.

For the China IV standard, the nitrogen oxide emissions of light vehicles are reduced by 25%, and the nitrogen oxide emissions of heavy vehicles are reduced by 43%.

3. The upper limit of sulfur content for gasoline is different.

The upper limit of sulfur content of China IV standard gasoline is 150mg kg.

The upper limit of sulfur content of China V standard gasoline is 50mg kg.

The country (country) means that the vehicle engine system and emission standard test are set in accordance with compatibility, which belongs to the transitional model, when the vehicle uses 93 national standard gasoline and diesel, the system is recognized; When using 92 standard gasoline and diesel, the system will monitor the changes, and the stroke computer will adjust the fuel injection volume and valve by itself to achieve the best working condition. As for whether you can get a license, you need to consult the local motor vehicle management office, and the policies are different in different places.

1. The upper limit of sulfur content of China IV standard gasoline is 150mg kg, the upper limit of sulfur content of China V standard gasoline is 50mg kg, and the upper limit of sulfur content of China VI standard gasoline is 10mg kg.

2. The upper limit of sulfur content of China V standard gasoline is 50mg kg; Due to the problem of using oil products in automobiles, the third stage (China III) emission standard is currently implemented for light-duty diesel vehicles, and the fourth stage (China IV) emission standard is implemented for light-duty gasoline vehicles. One level higher in the future.

The so-called country V country VI represents the national automobile emission standard, first of all, the biggest difference between them is the different time of the implementation of the standard.

It refers to the domestic emission standard of the car, the national LV is the domestic level 4 standard, and the national V is the domestic level 5 standard, and the latter is more upscale than the former.

For diesel vehicles, the nitrogen oxide (NOx) emission limit has been tightened by 28%, the sum of hydrocarbons and nitrogen oxides (HC+NOx) indicators have been tightened by 23%, and the particulate matter concentration (PM) limit for diesel vehicles has been increased by 82%! There is also a new particulate matter particle count (PN) that is also aimed at diesel vehicles, and the PN standard only detects diesel vehicles. Compared with gasoline vehicles, the China V emission standard obviously has higher requirements for diesel vehicles.

The oil quality is better, the combustion value is higher, the full use is made, and the environmental pollution is relatively less.

It is a different emission standard, the national five standard, the exhaust gas of the emission is cleaner, at present, many developed provinces of the national four emissions are not licensed, but in Anhui and other places can be licensed.

It refers to the domestic emission standard of the car, China IV is the domestic level 4 standard, and China V is the domestic level 5 standard, and the latter is one grade higher than the former.

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. In order to curb the production of these harmful gases and prompt automobile manufacturers to improve their products to reduce the source of these harmful gases, Europe and the United States have formulated relevant automobile emission standards.

The national LV 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 active layer of better catalytic converters, control and reduce the emission of pollutants from automobiles to below the specified value of the standard.

In the China V standard, the nitrogen oxide (NOx) emission limit for gasoline vehicles is 25% stricter than that of China LV, and new standards for testing hydrocarbons other than methane (NMHC) and particulate matter concentration (PM) for gasoline vehicles with direct injection in the cylinder have been added.

The "China V" emission standard is equivalent to the Euro V standard, and Europe officially implemented the latest Euro V standard 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.

Recently, I often receive relevant messages from sleepy friends about "what is the difference between VL and V in the country of cars", and now I will explain it to you. The emission standards met by the two vehicles are different, and the three-way catalytic converter structure is different, and the calibration procedures in the engine are also different. The car of China VI is more expensive than the car of China V, and after the implementation of China VI emissions in many regions, the car will not be listed, so we must see what kind of emission standards the car meets when buying a car.

Parafluid. The China VI emission standard was implemented in 2019, and the country's strict emission standards are to restrain car companies, so that car companies can make more environmentally friendly cars.

With the increasing seriousness of the global environmental pollution problem, countries around the world are introducing stricter emission standards, which is good for protecting the earth's environment.

Major car companies around the world are also actively developing pure electric vehicles and plug-in hybrid vehicles, and the country has also introduced policies to encourage consumers to buy new energy vehicles.

The purchase of new energy vehicles does not need to pay purchase tax.

New energy vehicles include pure electric vehicles and plug-in hybrid vehicles.

Plug-in hybrid vehicles are different from ordinary hybrid vehicles, which cannot use an external power source to charge the power battery, and plug-in hybrid vehicles can use an external power source to charge the power battery.

Plug-in hybrids have a longer range in all-electric mode, which has lower tailpipe emissions and is more environmentally friendly.

Automobile country V is the "national fifth stage motor vehicle pollutant emission standard", which requires particulate matter emission limits to be below (China), in addition, carbon monoxide, hydrocarbons and nitrogen oxides and other gas emissions in the exhaust are required to be reduced.

The China V standard is comparable to the emission level of light vehicles implemented in Europe in Phase 5. It means that all light gasoline vehicles and heavy diesel vehicles (passenger cars and buses, sanitation, and postal purposes) manufactured, imported, sold and registered must meet the requirements of the China V standard.

Automobile country V is the "national fifth stage motor vehicle pollutant emission standard", which stipulates that the emission limit of particulate matter is below (the country is, and the emission of carbon monoxide, hydrocarbons and nitrogen oxides and other gases in the exhaust gas is reduced. The China V standard is comparable to the emission level of the fifth stage of light vehicles implemented in Europe.

It means that all light gasoline vehicles and heavy diesel vehicles (passenger cars and buses, sanitation, and postal purposes) manufactured, imported, sold and registered must comply with the provisions of the National V standard.

Since 2019, many cities or regions across the country have been gradually implementing the China VI standard, which is also the latest emission standard and the most stringent emission standard.

Because the China VI emission standard is more stringent than that of China V, the country estimates that China VI A will be implemented first this year, and then China VIB in 2023.

However, the latest information has been announced: since January 1, 2019, Beijing, Tianjin, Hebei, Shandong, and Henan provinces (Chawanjian City) have implemented China VI emission standards for light vehicles ahead of schedule.

The implementation of the National VI emission standards has already caused a chain reaction.

Fourth, the value retention rate of the national five models, the large number of new energy vehicles to seize the market, and the car series that meet the national VI emission standards on the virtual city, etc., but the owners are miserable and still do not meet the national VI standards of vehicles facing the dilemma of restricting registration and licensing.

After the implementation of the National VI standard, the implementation of the exhaust capacity of the car will be upgraded, which means that it is more difficult for the owner to pass the annual inspection exhaust gas detection, and the National V is likely to face the situation that it is difficult to get a license or cannot get a license.
