The difference between National 5 and National 6 vehicles mainly lies in the reduction level of harmful substances in exhaust emissions. The methods to distinguish between National 5 and National 6 vehicles are as follows: 1. Emission Label: The label for National 5 emission standard is V, while the label for National 6 emission standard is Ⅵ. 2. Vehicle Certificate: The vehicle certificate will indicate the emission standard of the vehicle. 3. Environmental Information List: The environmental information list accompanying the vehicle specifies the exhaust emission standard of the car. Information about National 5 and National 6 standards is as follows: 1. National 5: The National Fifth Stage Motor Vehicle Pollutant Emission Standard, known as "National 5 Standard," has an emission control level equivalent to the European Stage 5 emission standard currently in effect. 2. National 6: The National Sixth Stage Motor Vehicle Pollutant Emission Standard is formulated to implement the "Environmental Protection Law of the People's Republic of China" and the "Air Pollution Prevention and Control Law of the People's Republic of China," aiming to prevent pollution from exhaust emissions of compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and ensure human health.

When did China implement the National IV vehicle standard?

National IV vehicles were introduced in 2011. The National IV emission standard was implemented starting in 2011 and remained in effect until 2018 when the National V standard was introduced. Vehicles produced between 2011 and 2017 adhered to the National IV standard. Below is an introduction to the National IV emission standard: 1. The full name of the 'National IV standard' is the National Fourth Stage Motor Vehicle Emission Standard, which is equivalent to Europe's 'Euro IV standard'. 2. The National IV emission standard is the fourth stage of China's motor vehicle pollutant emission standards. The main pollutants emitted by vehicles include HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), and PM (particulate matter). 3. The National IV standard requires that the emission levels of various pollutants be approximately 50% lower than those of the National III standard. This is achieved through the application of technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, which control and reduce vehicle emissions to levels below the specified standards.

What are the effects of driving a new car on the highway for long distances?

Driving a new car on the highway for long distances has certain effects on the car, but the impact is not significant and will not affect the normal use of the vehicle. Precautions for driving a new car on long trips: It is recommended that owners allow a break-in period after purchasing a new car. If it is necessary to drive on the highway, the car's speed should be kept within a reasonable range. Avoid pushing the engine RPM or vehicle speed too high to prevent damage to the engine. Effects of driving a new car on long trips: When the engine operates at high speeds, the mechanical wear inside the engine can be significant. Additionally, the oil in a new car contains the highest amount of metal debris during this period. Using oil with a large amount of debris for high-speed driving can increase engine wear. In severe cases, it may cause irreversible damage, preventing the vehicle from reaching its optimal condition after the break-in period.

How to Identify the Authenticity of a Driver's License?

The methods to identify the authenticity of a driver's license are as follows: 1. Online verification: A driver's license can also be verified for authenticity by connecting to the public security network.

Check the anti-counterfeiting marks: There is a significant difference between the anti-counterfeiting marks of genuine and fake driver's licenses. The anti-counterfeiting marks on a genuine license, such as the characters "China," are composed of dot matrix graphics, appearing blurry; whereas fake licenses use vector graphics with block-like strokes, making them clearer. 3. Laser anti-counterfeiting marks on the plastic seal: On the upper right side of the driver's license, there are the words "China," "CHINA," "Driver's License," and "DRIVING LICENSE." These can be clearly seen when viewed at an angle under light. There is also a prominent five-pointed star on the lower right side of the license, and the laser five-pointed star must overlap the photo.
