What is the difference between China VI and VIB of automotive environmental protection standards?

Difference Between Country V and Country VI:

1. Different sulfur content.

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

2. Different numbers of particles.

Compared with the VI, the NOx emission standard for domestic V gasoline vehicles has been increased by 25%, and the NOX emission standard for diesel vehicles has been increased by 28%.

3. Different endurance mileage.

Compared to VI, V increased from 80000 km to 160000 km.

4. The execution time is different.

In December 2014, the national VI standard was implemented. In December 2017, the national V standard was implemented.

Extended information: The national "V" emission standard is equivalent to the European V standard, and the latest European V standard has been officially implemented in Europe since September 1, 2009.

In 2012, Beijing plans to implement the national V standard, and once Beijing fully implements the national V emission standard, it means that vehicles that do not meet the emission standard cannot be sold in Beijing.

Previously, in order to control vehicle pollution, Beijing has been implementing relevant national standards in advance. In order to cooperate with the implementation of the national V emission standard, Beijing will further improve the quality of oil products to comply with the national V standard.

The difference between country VI-B and country VI is:

1. Difference 1: The implementation time of country 6-b and country 6 is different. China VIA is enforced for light vehicles on July 1, 2020, while China VIB is mandatory on July 1, 2023.

2. Difference 2: China VIA is a transitional stage from China V to China VI, while China VIB is three years after China VIA, which is the formal stage.

3. Difference 3: China VIB is 29% stricter than China VIA in terms of carbon monoxide emission limit, and hydrocarbon emissions are 50% stricter.

The similarities between China V and China VI are: 1. The CO emission required by China VI is 50% lower than that of China V; 2. The national VI standard stipulates that the emission of total hydrocarbons and non-methane total hydrocarbons is 50% lower than that of China V; 3. The emission of nitrogen and hydrogen compounds is also 42% lower than that of China V; 4. The emission standard of China VI is more than 30% stricter than that of China V. The sixth national emission standard is an improved version of the current fifth national emission standard.

Compared with the national fifth emission standard, there are stricter emission limits for CO, total hydrocarbons, total non-methane hydrocarbons, nitrogen oxides and particle mass. At the same time, new Macro regulations on particle quantity emissions have been added. Under the Sixth National Emission Standard, emissions of carbon monoxide gas, hydrocarbons, total non-methane hydrocarbons and nitrogen oxides from light fuel trucks will be reduced by about 50 per cent, and particulate matter emissions will be reduced by less than 40 per cent compared to the fifth National Emission Standard.

For ultra-heavy-duty diesel vehicles, nitrogen oxides and particulate matter will be reduced by more than 60% compared with the National Fifth Five-Year Plan period.

Which is better, country V or country VI, country V or country VI? A lot of people don't know yet. Now let's take a look!

1.Differences in environmental protection standards between countries: The difference between countries is that the emission standards are different, and China is more stringent.

2.China VI is divided into two phases, A and B, which will be implemented on July 1, 2020 and July 1, 2023 respectively. Country 6a is equivalent to the transition standard from country 5 to country 6, and country 6b is six times that of the real country.

3.Compared with vehicles with China V emission standards, I personally think that China V emission standards are better, because China V emission standards are one stage lower than China VI emission standards.

1.This represents the China 6 emission standard.

Since January 1, all cities and regions in the country have gradually begun to implement the China VI emission standard, which is known as the strictest emission standard in history.

3.The state has introduced strict emission standards to restrain automobile manufacturers, so that automobile manufacturers can make more environmentally friendly vehicles. At the same time, stricter emission standards can also eliminate some old cars that do not meet emission standards.

4.In the past, it was common to see large-displacement 6-cylinder or even 8-cylinder vehicles on the road, but now these cars are almost gone. Many D-segment luxury cars use small-displacement turbocharged 4-cylinder engines.

5.Car displacements are getting smaller and smaller, and vehicle exhaust emissions are getting lower and lower, which is the trend of the future. With the development of science and technology, there will be more and more hybrid and pure electric vehicles on the road, and pure gasoline vehicles will gradually be eliminated.

6.Many automakers are actively developing hybrid and pure electric vehicles, which is the only way out for car manufacturers under strict emission standards.

7.After the national 6 standard comes out, the national 2 standard car will be completely eliminated, and the national 3 and national 4 cars will be subject to some restrictions. In some poor and starving areas, the National 4 car is no longer licensed. After the sixth country comes out, the fifth country may not be restricted.
