1. Ethanol gasoline is a gasoline with ethanol added, and the amount of gasoline added varies from country to country, and the letter E is added before the gasoline label to distinguish it from ordinary gasoline.
2. **Same as regular gasoline**.
3. According to the actual test situation, adding 10% ethanol has a relatively small impact on the power system and can be ignored, but usually more than 20% ethanol gasoline needs to change the design of the engine and its related parts, and the material needs to be changed to adapt to the influence of ethanol gasoline.
The advantages of ethanol gasoline over regular gasoline are:
1) High octane number (about 110), which can replace lead-free anti-knock additive methyl tert-butyl ether.
2) Ethanol is an oxygenated fuel with a high latent heat of evaporation, which can reduce emissions.
3) Ethanol is an excellent solvent, which can effectively eliminate the condensation of fuel impurities in the fuel tank and oil circuit system.
The disadvantages are: 1) the low calorific value of ethanol is lower than that of gasoline, and ethanol is 62% of gasoline; However, the theoretical amount of air when ethanol is burned is also small, and ethanol is 60% of gasoline.
2) Due to the high latent heat of evaporation of ethanol gasoline, it is not conducive to the evaporation of fuel at low temperature, especially in the cold winter, which is easy to cause difficulty in cold start of the engine. At the same time, the boiling point of ethanol is low, and it is easy to produce gas resistance at high temperatures, so that the oil supply is reduced or interrupted.
3) The shelf life of ethanol gasoline is shorter than that of ordinary gasoline, and it is easy to stratify after exceeding the shelf life.
4) Ethanol is an excellent solvent, and it is also easy to corrode, soften, swell or crack rubber parts and synthetic non-metallic materials.

Ethanol gasoline is ordinary gasoline with a certain proportion of ethanol added, ** similar, whether the power system needs to be modified depends on the proportion of ethanol in ethanol gasoline, at present, the domestic is generally 10%, can be used without modification, comprehensive fuel consumption will rise, power will decline, because the actual engine is calibrated according to gasoline, there is no adaptability change, so ethanol gasoline has more disadvantages.

1.The difference between ethanol gasoline and regular gasoline is that the ethanol in ethanol gasoline is a renewable resource, generally fermented from sorghum, corn, potatoes, etc., while regular gasoline is a non-renewable resource.
2.Compared to regular gasoline, ethanol gasoline is more environmentally friendly and can also reduce vehicle exhaust emissions and pollution. The gas pollution caused by ordinary gasoline is more serious, and automobile exhaust is also an important part of China's air pollution.
The calorific value of ethanol is 60% of that of ordinary gasoline, so ordinary gasoline is better than ethanol gasoline in terms of power performance and fuel economy. That is, the ethanol gasoline will be separated from the water, and the water will settle at the bottom of the tank. When the vehicle uses ethanol gasoline for the first time, you need to check the fuel tank first to see if the water in the fuel tank affects the engine work.

The differences between ethanol gasoline and regular gasoline are as follows:
1. The calorific value of ethanol gasoline is different from that of ordinary gasoline: the calorific value of ethanol is only 60% of that of conventional vehicle gasoline. Therefore, it will be worse than pure gasoline in terms of power and fuel economy.
2. The resources of ethanol gasoline and ordinary gasoline are different: the ethanol in ethanol gasoline is a renewable resource, which can be made by fermentation of sorghum, corn, potatoes, etc., which is more environmentally friendly; But pure gasoline is not renewable.
3. The environmental impact of ethanol gasoline and ordinary gasoline is different: ethanol gasoline, as a vehicle fuel, can save petroleum resources, reduce air pollution from automobile exhaust, and promote agricultural production. Gasoline exhaust can pollute the environment.
Precautions for using ethanol gasoline in automobiles
Ethanol gasoline is mixed with a certain amount of denatured fuel ethanol, ethanol is a hydrophilic liquid, easy to misc with water, unlike gasoline, gasoline can be separated from water, and the water is deposited at the bottom of the tank.
Therefore, when the vehicle uses ethanol gasoline for the first time, it should be inspected in the fuel tank to prevent the ethanol gasoline from miscible with the sedimented water that may exist at the bottom of the fuel tank, so that the water in the oil exceeds the standard and affects the normal operation of the engine. The fuel system of the car should be cleaned before using ethanol gasoline.

1. The composition is different.
Ethanol gasoline is a new type of alternative energy formed by mixing ethanol and ordinary gasoline into fuel processed from grain and various plant fibers in a certain proportion. According to China's national standard, ethanol gasoline is made by blending 90% ordinary gasoline with 10% fuel ethanol.
The English name of gasoline is petrol (English), the appearance is a transparent liquid, flammable, the distillation range is 30 to 220, the main components are C5 C12 aliphatic hydrocarbons and naphthenic hydrocarbons, and a certain amount of aromatic hydrocarbons.
2. The impact on the environment is different.
Ethanol gasoline as a vehicle fuel can save petroleum resources, reduce air pollution from automobile exhaust, and promote agricultural production.
Gasoline exhaust can pollute the environment.
1. Different characteristics: ethanol gasoline uses fuel ethanol as a gasoline additive, which is environmentally friendly, clean and renewable. Ordinary vehicle gasoline is the use of chemical agents such as MTBE as raw materials as gasoline additives, which has great pollution to the environment, and many countries have banned additives such as MTBE. >>>More
1. Gasoline marking identification.
Ethanol gasoline is indicated by the letter "E" before the gasoline designation. 7a686964616f31333431346461 >>>More
Expensive oil has become an indisputable fact, we have surpassed the United States to become the world's first oil nation and the world's largest oil importer, but in terms of refining technology, our technology is not the best, it can only be a second-class existence,Fuel is closely related to the lives of ordinary people, because oil is imported in large quantities and the smelting technology is not top-notch, so it is difficult for our fuel** to keep up with international standards. >>>More
If you look at it from an environmental point of view, it is undoubtedly better to ethanol gasoline, because the ethanol in ethanol gasoline is a renewable resource, and as a car energy source, its emissions will be cleaner; However, pure gasoline has limited resources and causes great pollution to the atmosphere, so it is not easy to become a strategic energy source in the long run.
Because you don't have the option to refuel gas, just choose to use or not to use. And as long as you drive, you don't have a choice, so this is caused by the asymmetry between supply and demand. Don't think too much about it, choose to accept it happily. >>>More
