What is the difference between Beijing Standard 92 Gasoline and National Standard 92 Gasoline?

1. The standards are different.

National Standard Gasoline: This standard applies to the whole country. The main indicators of the national standard for the fifth stage of motor gasoline are equivalent to the current standard level in Europe, which meets the requirements of China's fifth stage of the pollutant emission standard for gasoline vehicles.

According to the notice issued by the Ministry of Finance, the Ministry of Environmental Protection and other seven departments on the issuance of the "Work Plan for Accelerating the Quality Upgrading of Refined Oil", the scope of implementation of the National V standard for automotive gasoline and diesel will be expanded. Since January 1, 2016, the eastern region of China has fully met the national V standard of automotive gasoline (including E10 ethanol gasoline).

From January 1, 2017, the country will fully meet the national V standard of automotive gasoline (including E10 ethanol gasoline), and at the same time stop domestic sales of automotive gasoline lower than the national V standard.

Beijing standard gasoline: This standard is only applicable to the region, taking Beijing as an example, the Beijing Municipal Commission of Commerce officially issued the "Notice on the Implementation of the Fifth Phase of Beijing Vehicle Gasoline and Diesel Standards" in May 2012. The "Notice" said that from 0:00 on May 31, 2012, Beijing will implement two new local standards for vehicle gasoline and diesel, namely the "Beijing" fuel standard.

The adjusted standards are generally stricter than the national fifth-stage recommended indicators, and are basically in line with the European standards at the same stage.

2. Gasoline ** is different.

National standard 92 gasoline **: At present, the national 92 gasoline ** is around the yuan liter, after the price adjustment is implemented, 92 gasoline will return to the '7 yuan era.

Beijing Standard No. 92 Gasoline **: Gasoline and diesel will be adjusted from 24 o'clock on December 28, 18, and the retail price of No. 92 gasoline will be yuan.

Beijing Standard No. 92 gasoline is a new fifth-stage standard gasoline issued by Beijing in May 2012, which is a local standard, not a national standard. The most significant changes are the reduction of the sulphur limit from 50 mg/kg to 10 mg/kg and the manganese limit from grams per litre to grams per litre. At the same time, the octane number and anti-knock resistance of gasoline have been reduced, and its anti-knock index has been modified to "not less than".

In actual use, 92 is no different from the original national standard 93 gasoline. Note: The grade of gasoline is determined by its octane number, and the octane number is an important indicator to measure the anti-knock resistance of gasoline; The higher the grade of gasoline, the better its octane number and knock resistance.

On December 18, 2013, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China and the Standardization Administration of the People's Republic of China jointly issued the fifth phase of the national standard for automotive gasoline ———automotive gasoline" (GB 17930-2013 instead of GB 17930-2011). The most important changes can be summarized as "three reductions, two tones, and one increase".

"Three reductions" refers to the reduction of the limit of sulfur mass fraction from 50 g g to 10 g g in the fourth stage, which is reduced by 80%; The limit of manganese mass concentration index was reduced from 8 mg L to 2 mg L in the fourth stage, and the artificial addition of manganese-containing additives was prohibited. Reduce olefin content from 28% to 24% in Stage 4.

"Two-tone" refers to the adjustment of vapor pressure and grade. Among them, the lower limit of vapor pressure in winter was increased from 42 kPa in the fourth stage to 45 kPa, and the upper limit of vapor pressure in summer was reduced from 68 kPa in the fourth stage to 65 kPa, and the summer vapor pressure was implemented in Guangdong, Guangxi and Hainan throughout the year. At the same time, taking into account the fifth stage of motor gasoline.

Due to the reduction of octane number caused by sulfur reduction and manganese ban, as well as the shortage of domestic high-octane number resources, combined with the actual situation of the oil refining industry, the standard adjusts the grade of motor gasoline from No. 90, No. 93 and No. 97 to No. 89, No. 92 and No. 95 respectively.

One addition is to add the technical requirements and test methods of No. 98 motor gasoline ( in the appendix of the standard. It is estimated that the implementation of "vehicle gasoline" (GB 17930-2013) will greatly reduce vehicle pollutant emissions, and it is estimated that the vehicles in use can reduce nitrogen oxides by about 300,000 tons per year, and the new cars can reduce nitrogen oxides by about 90,000 tons in 5 years.

Difference: Beijing Standard is a local standard.

The national standard is the national standard. In order to consider the differences in various regions of the country, the national standards are generally set in a wide range, but the landmarks will be more in line with the actual situation of the region and more stringent, and Beijing's environmental protection requirements are very high.

Ethanol. Oil is a fuel oil blended with a certain amount of ethanol. Since the product of ethanol combustion contains water, the long-term use of ethanol oil should regularly add dehydrating agent to the oil tank, and there is no problem in mixing ethanol oil with gasoline in the short term.

Regarding the comparison of 97 and 93 fuel, there is also a need to consider the oil according to the parameters of the car you purchase, and you don't have to blindly pursue a high grade. A high oil grade represents a high cleanliness index and carbon deposit.

Less formed. However, the formation of carbon deposits is related to many factors such as fuel quality, driving style, regional air, and oil maintenance, so it is not possible to avoid carbon deposits by using high-grade fuel.

The measurement standards for the Beijing Standard 92 car and the national standard 92 gasoline are different. Beijing Standard No. 92 gasoline is Beijing's fuel standard chain filial piety, while national standard No. 92 gasoline is the national measurement standard, so the two types of No. 92 gasoline are essentially different, because the measurement standard of gasoline itself is different.

The environmental protection requirements of Beijing Standard No. 92 gasoline and National Standard No. 92 car are different. Because the Beijing standard is Beijing's standard, it will be restricted according to the environmental conditions of Beipeng Huai manuscript Beijing, so it is relatively strict compared to the national standard.

The fuel quality and information of Beijing Standard No. 92 gasoline and National Standard No. 92 gasoline are different. The fuel quality of the Keibu 92 gasoline will be better.

Almost every friend who has driven a car will have the experience of refueling at the gas station in the past, and when we get to the gas station, we also know that there are usually several grades of oil in the gas station for us to choose, among which we add more 92 and 95 gasoline, so what is the difference between 92 gasoline and 95 gasoline? Let's talk about this today.

The most direct difference between No. 92 gasoline and No. 95 gasoline is actually **, which is also visible to everyone, no matter how the oil price is adjusted, No. 95 gasoline is usually about 5 cents more expensive than No. 92 gasoline.

What's the difference behind the difference? In fact, we first need to know what the gasoline label means. For example, the ratio of isooctane to n-heptane in No. 92 gasoline is 92% to 8%, and the ratio of isooctane to n-heptane in No. 95 gasoline is 95% to 5%.

Isoctane has good knock resistance, so the higher the grade, the better the knock resistance.

The knocking itself has a negative impact on the vehicle engine, and the knocking will not only cause damage to the piston rod, valve, cylinder wall, crankshaft and other components of the engine, but also cause problems such as carbon deposition in the engine, so the use of high-grade gasoline also plays a certain role in protecting the engine.

So when we refuel, is it better to choose the higher the grade of gasoline? What we need to know is that the gasoline label only determines the anti-knock resistance of the gasoline, not the cleanliness of the gasoline, and there is no difference in the cleanliness between different grades of gasoline, so the so-called "the higher the grade of the gasoline, the purer the purity" is actually a misunderstanding.

In fact, different engines have different requirements for gasoline labeling, at this time we have to talk about another parameter is the compression ratio, the engine with a high compression ratio is more likely to cause knocking, so it is necessary to choose high grade gasoline with high knock resistance to avoid detonation in the engine as much as possible.

But in fact, we only need to fill gasoline according to the manufacturer's requirements, for example, Volkswagen's turbocharged engine usually requires 95 gasoline, at this time, adding 92 gasoline will definitely not meet the official requirements of anti-explosion, but for example, Mazda's engine usually only needs to be filled with 92 gasoline, at this time we fill 95 gasoline, although there is no problem, but in the anti-knock performance exceeds the manufacturer's requirements, it will only cost more money in vain, Therefore, when we refuel, we must not choose the higher the grade of gasoline, the better, according to the manufacturer's label to choose the right gasoline label for your car.

The main thing is to look at the compression ratio of the car itself, the higher the compression ratio, the greater the number of oil selected.

What exactly is the difference between 92 and 95 gasoline? A lot of people misunderstand!

Summary. Hello dear, I personally think that Beijing Standard 92 gasoline is better Beijing Standard is a local standard, and the national standard is a national standard. In order to consider the differences in various regions of the country, the national standards are generally set in a wide range, but the landmarks will be more in line with the actual situation of the region and more stringent, and Beijing's environmental protection requirements are very high.

The differences between Beijing Standard No. 93 and National Standard No. 93 gasoline are as follows:

1. The standards are different.

Jingbiao No. 93 belongs to the national five standard of Beijing standard, and Guobiao 93 belongs to the national standard.

2. The composition is different.

Beijing Standard does not contain ethanol, and the power is good, which is more environmentally friendly and energy-saving. The national standard contains ethanol, which has poor power and is not environmentally friendly.

3. **Different.

The Beijing standard ** is higher, and it can only be added in the Beijing area. The national standard is cheap, and it can be added all over the country.

The detonation point of the national standard 93 is only slightly earlier than that of the Beijing standard 93, and the desulfurization process of the Beijing standard 93 is better and relatively more environmentally friendly. No. 93 gasoline can be roughly understood as a mixture of isoalkanes and n-alkanes in a ratio of 93:7.

The change of No. 93 to No. 92 means that the isoalkanes, which have a decisive influence on the octane number, have been reduced by 1% from about 93% to about 92%; The change of No. 97 to No. 95 means that the isoalkanes have been reduced from about 97% to about 95%. Therefore, the fundamental properties and purity of gasoline do not change, only the detonation point is slightly advanced.

It is best not to mix, it has a great impact on the motor of the aftermath, especially for cars with higher prices, which can easily lead to engine failure.

Introduction to the difference between No. 95 gasoline and No. 92 gasoline: 1. The applicable compression ratio is different: generally speaking, cars with compression ratios between should generally use No. 92 gasoline; Cars with a compression ratio greater than 95 should use No. 95 gasoline.

2. The octane number is different: the octane number of No. 92 gasoline is lower than that of No. 95 gasoline. That is, No. 92 gasoline contains isooctane 92, and No. 95 gasoline has a caprycane crude alkane number of 95.

3. The price of oil is different: the unit price of No. 92 gasoline is cheaper than that of No. 95 gasoline. The following is an introduction to the relevant content No. 95 gasoline and No. 95 gasoline can not be mixed strictly speaking, but their chemical composition and other aspects are relatively close, and the seismic ability is strong.

2. In some areas, there is low-grade 90 gasoline, if mixed with high-grade gasoline, it will cause detonation, lack of electricity and other phenomena, and will affect the life of the spark plug, and will also bring more exhaust pollution.
