In what part can you see the number of countries in which the car is

First, the simplest and most direct is to look at the vehicle's environmental protection signs, which are clearly marked behind the signs

2. Log in to the Motor Vehicle Exhaust Pollution Supervision and Management Center** for inquiry.

3. Take the motor vehicle registration certificate (original or copy is acceptable) to the vehicle management office for inquiry.

Fourth, if it is a new car, you can find the vehicle factory certificate and look for it inside. However, the certificate of conformity of the general car is placed in the DMV. Therefore, when buying a new car, it is recommended to make a copy for future use.

Fifth, according to the year of the car on the license plate to make a rough distinction.

Most of the cars after 2008 are China IV;

In 2007, some of the cars were in the third country, and some were in the fourth country;

Before 2007, the cars were basically under the fourth national level, that is, the national level.

Three, the second car;

The cars before 2005 were basically national second cars;

By mastering these methods, you can determine what the emission standards of your car are.

1. There is no place to see this emission standard on the car: if it is a new car, look at the certificate; If it's a second-hand car, look at the environmental protection annual inspection sticker on the front windshield.

2. The national number is the national automobile emission standard for several stages, that is, the automobile emission standard.

Emission standards for light vehicles.

The emission standards for light vehicles were issued in July 1999 and revised in 2001.

The first stage: pollutant emission limits and measurement methods for light vehicles (I), which is equivalent to the EU 93 59 EC directive, with reference to the use of part of the technical content of the 98 77 EC directive, is equivalent to Euro I, issued and implemented from April 16, 2001;

The second stage: light vehicle pollutant emission limits and measurement methods ( ) equivalent to the EU 96 69 EC directive, with reference to the use of 98 77 EC directive part of the technical content, equivalent to the EU, from July 1, 2004 implementation;

Phase III: Emission Limits and Measurement Methods for Light Vehicles (China, Phase), which is partially equivalent to Europe, will be implemented in 2007;

Phase 4: Emission Limits and Measurement Methods for Light Vehicles (China, Phase), which is partially equivalent to Europe, will be implemented in 2010.

China's light vehicle emission standards are exactly the same as those of Europe and Europe in terms of pollutant emission limits, but some improvements have been made in experimental methods, and there are also great differences in the format of regulations from European standards.

The most accurate method to tell you the most accurate method, enter the motor vehicle environmental protection network, new car certification, enter the engine number and manufacturer name, search will come out of the certification announcement of this car, the announcement clearly states that it belongs to the national emissions. If you find it more difficult, send me the model of the vehicle and I will check it for you. 2. Vague definition According to the age, it is roughly produced after September 2009 (note that it is produced not for sale) All are national 4 models (light vehicles) July 2007 - September 2009 The production is national 3 models July 2004 - July 2007 before the national 2 before 2004 - yellow label car.

Brother Xinge teaches you how to check, the car is the emission of the country, it is so simple.

The easiest way to check the car exhaust emission standards is: the simplest and most direct is to look at the front windshield, which has the car environmental protection logo on it, and the signs are basically clearly marked.

You can also log in to **Motor Vehicle Exhaust Pollution Supervision and Management: Motor Vehicle Environmental Protection Network for inquiry. When looking for the information given by the dealer when buying a car, most of them start from the page of car consistency or the first page of the car certificate.

If you can't find it, take the car registration form, or a copy, and go to the DMV to check.

A rough identification is made based on the year of the license plate on the car. Compared with the "China V" standard, the "China VI" will strictly control the emission limits of pollutants, excluding the influence of working conditions and tests, the carbon monoxide emissions of gasoline vehicles will be reduced by 50%, the total hydrocarbon and non-methane total hydrocarbon emission limits will be reduced by 50%, and the nitrogen oxide emission limits will be tightened by 42%.

How to look at the national number of automobile emission standards.

Hello friend 1, the most accurate way to tell you a most accurate method, enter the motor vehicle environmental protection network, new car certification, enter the engine number and manufacturer name, search will come out of the certification announcement of this car, the announcement clearly states that it belongs to the national emissions. If you find it more difficult, send me the model of the vehicle and I will check it for you. 2. Vague definition According to the age, it is roughly produced after September 2009 (note that it is produced not for sale) All are national 4 models (light vehicles) July 2007 - September 2009 The production is national 3 models July 2004 - July 2007 before the national 2 before 2004 - yellow label car.

Engine nameplate, vehicle nameplate.

If you have a new car, you will have it in the car manual, and you will also have it in the brochure

There is a small sign on the side of the B-pillar of the co-pilot with information about the vehicle.

Summary. 1.Look at the back of the label of the car environmental protection qualification mark, you can see the emission standard of the car; 2. The page at the beginning of the vehicle certificate has a description of the emission standard, but it is not directly written in the country, but a string of characters, you can search for the representative meaning of this string of characters on the Internet, and then know that it is the national emission standard.

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

What do you think of Che Ziguo? Where to look?

Hello dear! Now for you to answer <>

The car country is to look at the environmental protection mark of the vehicle, and there are obvious marks from the back of the sign.

1.Look at the back of the label of the car environmental protection qualification mark, you can see the emission standard of the car; 2. The page at the beginning of the vehicle certificate label has a description of the emission standards, but it is not directly written the national number, but a string of characters, you can search on the Internet for the representative meaning of this string of characters, and then know that it is the national emission standard. Vehicle emissions refer to harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, and PM (particulates, soot) emitted from exhaust gases.

They are all harmful gases produced by the engine during combustion.

The simplest and most direct way to look at the vehicle's environmental protection logo is to see the vehicle's environmental protection mark, which has obvious marks behind the sign; You can also log in to the Motor Vehicle Exhaust Pollution Supervision and Management Center** to inquire, and take the original or copy of the motor vehicle registration certificate to the vehicle management office for inquiry; In addition, it can also be queried on the vehicle factory certificate.

If you want to trace back to China's control of motor vehicle exhaust pollution, at that time in the last century ( check the transaction price |In the early 80s, China promulgated a series of motor vehicle exhaust pollution control emission standards, including "Gasoline Vehicle Idle Pollution Emission Standards", "Diesel Vehicle Free Acceleration Smoke Emission Standards", "Automobile Diesel Engine Full Load Smoke Emission Standards" and its measurement standards.

On July 1, 2001, China issued China's first-stage emission standards with reference to European emission standards, followed by the country.

II. Country. 3. Country.

Fourth, China V, each stage is more stringent than the previous stage of the emission standards. According to the year of the car's license plate, the cars before 2007 are basically below the fourth national level; Most of the cars after 2008 are China IV, and most of the cars from 2016 are China V standards.

At present, the implementation time of China VI emission standards will be divided into two phases: China VIA and China VIB, corresponding to July 1, 2020 and July 1, 2023. In fact, China VIA is only a transitional stage from China V to China VI, and by 2023, China VI emission standards will be fully implemented. (Photo by photo:.)

The way to see how many cars are in the country:

1. Check the environmental protection signs of the vehicle, which are clearly marked behind the signs.

2. Log in to the Motor Vehicle Exhaust Pollution Supervision and Management Center** for inquiry.

3. Take the motor vehicle registration certificate (original or copy is acceptable) to the vehicle management office for inquiry.

4. The new car is inquired on the vehicle factory certificate, but the general car certificate is placed in the vehicle management office, so when buying a new car, it is recommended to make a copy for retention.

5. Make a rough distinction according to the year of the car on the plate. Most of the cars after 2008 are China IV; In 2007, the cars licensed were three and four; Before 2007, the cars were basically under the fourth national level, that is, the national level.

Three, the second car; The cars before 2005 were basically national second cars;

National standard emission standards.

1. National standard: The national standard refers to the European standard, which is mainly for carbon monoxide, hydrocarbons and particulate emission limit requirements, carbon monoxide is grams per kilometer, hydrocarbons are grams per kilometer, etc. If the emission standard reaches the national one, it belongs to the national one car, and so on.

2. China II standard: China II standard reduces carbon monoxide emissions by 30% and hydrocarbons and carbon oxides by 30% compared with China 1 bicycle pollutant emissionsChina III standard: China III standard adds a vehicle self-diagnosis system and upgrades the three-way catalysis.

The total pollutant emissions of China III will be reduced by 40% compared with that of China II.

4. China IV standard: China IV has upgraded the emission treatment system compared with China III, which is a 50% to 60% reduction in pollutant emission standards compared with China III.

5. China V standard: Compared with China IV standard, China V standard reduces nitrogen oxide emissions by 25%, and also increases the emission limits of non-methane hydrocarbons and PM, reduces air pollution, and prevents haze.

6. China VI standard: The China VI emission standard has been increased by 40% to 50% on the basis of China V, which is higher than the Euro VI standard, comparable to the United States, and is basically one of the most stringent emission standards in the world.

1. Check the environmental protection signs of the vehicle, which are clearly marked behind the signs.

2. Log in to the Motor Vehicle Exhaust Pollution Supervision and Management Center** for inquiry.

3. Take the motor vehicle registration certificate (original or copy is acceptable) to the vehicle management office for inquiry.

4. The new car should be checked on the vehicle factory certificate.

5. Make a rough distinction according to the year of the car on the plate.

How to distinguish the symbols of the country's cars?

The symbol identification method of the national car is: i1, ii2, iii3, iv4, v5, vi6. From China 1 to China 6, the emission standards are different at different stages.

Under the conditions of the new policy, cars above China IV can still be legally on the road normally, and only some cities can legally use the road for cars below the country.

At this stage, the latest China VI standard is upgraded to a large extent compared with the China V emission standard, so there are two stages, China VIA and China VIB, of which in the China VI B stage, most indicators are 50% stricter than the China V standard, and the implementation of China VI can bring more than 10% significant improvement to urban air quality.

The easiest way is to look at the vehicle's environmental protection label, and the "emission standard" column will indicate the country's number. However, now the environmental label has been abolished, which means that there is no environmental protection label for vehicles now.

Knowledge points: The emission standards have been implemented since the beginning of the day, and the first standard is the so-called China 1, which has passed six standards after 20 years. The current standard is "6-a", and "6-b" will be fully implemented from the future; It is expected that the sixth level standard will be the highest and final standard for fuel-powered vehicles, and it is likely that the [ban on the sale of fuel vehicles] (comprehensive transformation of new energy vehicles) will be implemented after that

From country 1 to country 6 symbols respectively.

It is I, II, III, IV, V, VI, on July 1, 2000, the country first launched the national 1 emission standard, because it is with reference to the European emission standard, in line with the international standard, from the national 1 to the national mark 6 also uses Roman numerals. After that, new emission standards are introduced every few years.

The "China VI Standard Qi Grip" is divided into two stages, "China VI A" and "China VI B", and is planned to be uniformly implemented nationwide on July 1, 2020 and July 1, 2023 respectively. However, the six standards are extremely stringent, and their standards are much higher than the sixth stage emission standards in Europe and the tier3 standards in the United States, becoming one of the most stringent emission standards in the world, and the implementation time of the national six standards will be longer.
