What does the National IV standard for automobiles mean, and what does the National IV standard mean

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.

During the annual inspection of the vehicle, the emissions of the vehicle must meet this standard. Yesterday (April 8, 2010), the Beijing Municipal Environmental Protection Bureau announced three emission standards for motor vehicles in use and three local emission standards for oil and gas such as oil storage depots, fuel tankers, and gas stations. In 2008, Beijing began to implement the China IV emission standard, requiring new cars sold in Beijing to meet this standard.

What is the difference between the China IV standard for in-use cars announced yesterday and it? The relevant person in charge of the Municipal Environmental Protection Bureau said yesterday that the automobile exhaust emission standards are divided into new cars and vehicles in use. The emission standards of the vehicles in use are corresponding to the new cars, and there are national four standards, which require the owner to maintain the vehicle in time after purchasing the vehicle to ensure that the motor vehicle is stable and meets the emission standards.

He said that considering that the vehicle has been used for a period of time, the emission limit of the China IV standard for in-use vehicles is more lenient than the China IV standard for new cars. However, it is also 34% stricter than the limit of the China III standard. At present, Beijing for the National IV vehicles, the initial purchase is to be inspected every 2 years, and some of the National IV vehicles have to start annual inspections one after another.

In the annual inspection, the emission of the vehicle must meet the standard limit announced this time, otherwise it will be repaired and maintained, and the annual inspection can only be passed after reaching the standard. In addition, the newly promulgated oil storage depot, tank trucks, gas stations and other three oil and gas local emission standards, compared with the original standard, the oil storage oil and gas treatment device emission limit has been tightened by 25%, gas station emission standards have increased the gas station must be installed monitoring and oil and gas emission treatment device requirements, according to this standard, oil and gas efficiency can be increased by 5% to 10%, the monitoring system can monitor the working conditions of oil and gas equipment in real time. It is understood that the three emission standards for motor vehicles in use will be implemented from June 1 this year, and the three standards for oil storage, tank trucks, and gas stations will be implemented from July 1 this year.

The meaning of the China IV emission standard is:

1. The national IV emission standard is the national four-stage motor vehicle pollutant emission standard, and the main pollutants emitted by automobiles are HC (hydrocarbons), NOX (nitrogen oxygenate), CO (carbon monoxide), PM (particulates), etc., through the application of technologies such as better catalytic converter hidden active layer, secondary air injection and exhaust gas recirculation system with cooling device;

2. Considering that the vehicle has been used for a period of time, the emission limit of the National IV standard for the car in use is more relaxed than the National IV standard for new cars. However, it is also 34% stricter than the limit of the China III standard. For the National IV vehicles in Beijing, the initial purchase is to be inspected every 2 years, and some National IV vehicles have to start annual inspections one after another.

In the annual inspection, the emission of the vehicle must meet the standard limit announced this time, otherwise it will be repaired and maintained, and the annual inspection can only be passed after reaching the standard.

3. In addition, the newly promulgated oil storage depot, oil tanker, gas station and other three oil and gas emission standards, compared with the original standard, the oil storage depot oil and gas treatment device emission limit has been tightened by 25%, and the gas station emission standard has increased the requirements that the gas station must install the first monitoring and oil and gas emission treatment device, according to this standard sock hall standard, the oil and gas efficiency can be increased by 5% to 10%, and the monitoring system can monitor the working conditions of oil and gas equipment in real time.

Millions of car purchase subsidies.

The China IV standard is the fourth stage of the national motor vehicle pollutant emission standard.

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 (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 automobiles to the specified number of sufficiency below the standard.

Taking Beijing as an example, Beijing has implemented the National IV emission standards for diesel vehicles with light gasoline vehicles, buses, sanitation and postal systems in the city since November 2009, and has implemented the National IV emission standards for all diesel vehicles larger than tons since January 1, 2011.

Since July 1, 2011, all diesel vehicles less than Xun Li ton have implemented the national IV emission standards, ensuring that all new motor vehicles are fully licensed to implement the national IV emission standards, and combined with the annual inspection link to issue a unified national green and yellow environmental protection label, and gradually expand the restriction of yellow environmental protection mark vehicles.

1. The simplest and most direct way is to look at the environmental protection sign of the vehicle, which has obvious marks behind the signs. However, now the environmental protection label has been canceled, which means that there is no environmental protection label for the current vehicles, and only a few vehicles have the previous environmental protection label that has not been torn off.

2. If it is a new car, it can be viewed from the vehicle factory certificate or vehicle consistency certificate. You can see it by looking for the column of emission standards.

3. We can also log in to the motor vehicle environmental protection wang public inquiry platform for inquiries.

4. There is a simple distinction according to the year of the car, most of the after 2008 are the national four standards, between 2007-2004 basically the second national three cars, before 2004 are basically the second national two cars.

The difference between China V and China IV is that the standards for nitrogen oxides (NOx), hydrocarbons and nitrogen oxides (HC+NOx), and particulate matter concentration (PM) have been raised, and the standards for the number of particulate matter particles (PN) and hydrocarbons other than methane (NMHC) have been added to China V.

National Stage IV Motor Vehicle Pollutant Emission Standards:

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.

National Stage V Motor Vehicle Pollutant Emission Standards:

The national fifth-stage motor vehicle pollutant emission standard, that is, the "national five standard", the emission control level of the national fifth standard is equivalent to the fifth stage emission standard being implemented in Europe. The European Union has been in place since 2009 with stricter limits on vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide and particulates. From national to national, each time the standard is raised, bicycle pollution is reduced by 30 to 50 percent.

The fifth phase of the national motor vehicle emission standard will be implemented nationwide from January 1, 2017.

Beijing, Shanghai, Nanjing and other cities and some cities in Guangdong have begun to implement the National V standard.

From April 1, 2016, all imported, sold and registered light gasoline vehicles, light diesel buses and heavy diesel vehicles (for public transportation, sanitation and postal purposes only) in Beijing, Tianjin and Hebei must meet the "national" standards for motor vehicle emissions.
