1. Gasoline marking identification.
Ethanol gasoline is indicated by the letter "E" before the gasoline designation. 7a686964616f31333431346461
Ethanol gasoline is gasoline with added ethanol, and the amount of alcohol added varies from country to country.
Gasoline is marked with the letter E before the label to distinguish it from ordinary gasoline, such as ordinary gasoline 93 and ethanol gasoline 93 marked as E93
Internationally, E10 is commonly used to identify ethanol gasoline with 10% ethanol content, and E20, E85, etc. are respectively used to identify ethanol gasoline with 20% and 85% ethanol content.
Regular gasoline does not have a prefix letter, which is called regular gasoline.
Second, the internal impact of the car.
1. The calorific value of ethanol gasoline is lower than that of gasoline, resulting in a decrease in power.
2. It is easy to deteriorate, and the general shelf life is about 20 days.
3. It is easy to absorb water, which leads to stratification, water and ethanol sink, resulting in abnormal engine operation.
4. The swelling of the rubber parts of the fuel pipeline, the impact on the fuel pump oil level sensor, etc.
5. If you use ordinary gasoline for a long time in the past, you may suddenly change to ethanol gasoline, and there may be adverse reactions in a short time, such as fuel injector blockage, difficulty in starting, unstable idling, engine shaking and other problems.

1.After the implementation of the National VI emission standard, China's requirements for automobile exhaust emissions have become higher, and gas stations around the country have also been upgraded. In many places, No. 92 gasoline has been replaced by a new oil product, and the original No. 92 is also facing the fate of being "withdrawn", this new fuel is called "ethanol gasoline", that is, the gasoline that everyone sees at the gas station that starts with E, E92, E95...
2.At present, ethanol gasoline has been promoted in many places, you don't have to talk about "ethanol gasoline" color change, there are many rumors about ethanol gasoline on the Internet, pay attention to screening.
3.Ethanol gasoline is made by blending 90% ordinary gasoline and 10% fuel ethanol according to China's standards. Like regular gasoline, it is also available in a number of different models, namely E89, E92, E95 and E98.
4.As a new fuel, the biggest feature of ethanol gasoline is that it is more environmentally friendly, reduces the emission of harmful gases such as carbon monoxide, and is beneficial to the adjustment of energy structure.

1. Ethanol gasoline is more environmentally friendly than ordinary gasoline.
The ethanol in ethanol gasoline can be burned completely, so the hydrocarbon can be greatly reduced, which can reduce the pollutants in the exhaust of the car, thereby improving the air.
2. The latent heat of evaporation of ethanol is higher than that of ordinary gasoline.
The latent heat of evaporation of ethanol is higher than that of ordinary gasoline, which in turn can improve the engine air intake and combustion efficiency, and the oxygen content of ethanol gasoline is also greater than that of ordinary gasoline, resulting in a further increase in engine fuel injection.
3. The shelf life of ethanol gasoline is shorter than that of ordinary gasoline.
The shelf life of ethanol gasoline is shorter than that of ordinary gasoline, and the stratification phenomenon that ethanol gasoline is prone to occur after the shelf life is easy to become turbid in the tank.

1. The ingredients are different:Ethanol gasoline is made by blending 90% ordinary gasoline with 10% fuel ethanol.
2. Environmental protection is differentEthanol gasoline is more environmentally friendly than ordinary gasoline, and the ethanol in ethanol gasoline can be burned completely, so the hydrocarbon can be greatly reduced, which can reduce the pollutants in the exhaust of the car, thereby improving the air.
3. The latent heat of evaporation is differentThe latent heat of evaporation of ethanol is higher than that of ordinary gasoline, and the latent heat of evaporation of ethanol is higher than that of ordinary gasoline, which in turn can improve the engine air intake and combustion efficiency, and the oxygen content of ethanol gasoline is also greater than that of ordinary gasoline, resulting in a further increase in engine fuel injection.
Precautions for the use of ethanol gasoline for vehicles.
The ethanol in automotive ethanol gasoline has strong dissolution and cleaning properties. When the vehicle uses ethanol gasoline for the first time, especially after using 1 to 2 tanks of oil, under the cleaning action of ethanol, all kinds of impurities precipitated and accumulated in the fuel tank and oil circuit, such as rust, dirt, colloidal particles, etc., will be softened and dissolved, mixed into the oil, resulting in poor oil circuit.
Generally speaking, vehicles with a mileage of more than 30,000 kilometers and a dirty fuel supply system should be cleaned before using ethanol gasoline. The cleaning operation shall be carried out in the automobile repair plant with two or more qualifications, in strict accordance with the specifications, focusing on the fuel tank, fuel filter, oil pump, carburetor, fuel injector, oil circuit and oil circuit filter screen one by one.

1. Ethanol gasoline is blended by gasoline and ethanol, and ordinary gasoline has no ethanol component;
2. Ethanol gasoline is more environmentally friendly and can significantly reduce vehicle exhaust emissions;
3. The calorific value of ethanol gasoline is lower than that of ordinary gasoline, and it is worse than ordinary gasoline in terms of power and fuel economy;
4. The ethanol component in ethanol gasoline belongs to renewable energy, and ordinary gasoline is not renewable energy;
5. The water solubility of ethanol gasoline is very good, while the water solubility of gasoline is a little worse.
Question: How to mix ethanol gasoline?
Answer: tert-butanol 1% 5%, isopropyl acetate 1% 5%, methanol 5% 20%, ethanol gasoline 75% 90%. When preparing reformed ethanol gasoline, tert-butanol, isopropyl acetate, methanol and ethanol gasoline are taken in turn according to the ratio, and added to the static mixer in the above order for mixing.

1. Standing: First of all, Hu Xingqing takes out a part of the gasoline, then covers this part of the gasoline with a lid and seals it, and lets it stand for a few days, generally about 3 days, to observe whether the gasoline has obvious stratification, if there are two parts of liquid colorless and yellow. Then you're probably adding ethanol gasoline.
2. Add water and mix:
Add a small amount of water to the gasoline you take out, shake it well and mix it, at this time, you need to observe whether the gasoline becomes turbid, if the rental gasoline becomes turbid, most likely it is added to ethanol gasoline.
3. Look at the label:
The state stipulates that ethanol gasoline should be clearly marked, and if there is a letter "e" in front of the gasoline label, it is ethanol gasoline. Regular gasoline does not have a prefix letter, which is called regular gasoline.
The ethanol content of E10 ethanol gasoline is 10%, because the energy density of ethanol is lower than that of gasoline, according to calculations, the energy of ethanol gasoline per liter is about 3% lower than that of unleaded gasoline, and the fuel consumption of the original 10L will probably increase to about 10L after using E10 ethanol gasoline. At present, ethanol gasoline and ordinary unleaded gasoline are basically the same, for example, the oil price is yuan, 20,000 kilometers per year, fuel consumption is 10, from unleaded gasoline to ethanol gasoline, pants and land about 382 yuan more. When choosing ethanol gasoline, the fuel tank of the car must be cleaned, especially for cars that have been used for a long time, and the cleaning of the car fuel tank should be done.
It mainly plays a role in removing carbon and reducing air pollution. Reduce costs.
The root cause is because of the pandemic. Because disinfectant is to be used for disinfection, the disinfectant also needs ethanol as a raw material, because ethanol raw materials are in short supply. Therefore, in order to allow the normal production of disinfectant, ethanol gasoline was temporarily turned off. But this is all temporary. >>>More
The unit calorific value of ethanol is 60% lower than that of gasoline, and it is said that fuel consumption increases by only 4 5%. I believe in the theoretical situation. >>>More
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. >>>More
Different labels, in fact, many owners in China have some misunderstandings about their perceptions. The main component of gasoline is isooctane, and the essential difference between No. 95 and No. 92 gasoline is that the isooctane content of the two is different, the isooctane content of No. 92 gasoline is 92%, and the isooctane content of No. 95 gasoline is 95%. The higher the isooctane content, the higher the purity of the gasoline, and the better the knock resistance of the gasoline, which means that the combustion of No. 95 gasoline is more likely to be precisely controlled. >>>More
