What is the difference between ethanol gasoline and regular gasoline

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.

2. The evaporation potential is different: the evaporation potential of ethanol is greater, twice that of gasoline. This feature can improve the thermal efficiency of the engine and cool the engine.

Ethanol, commonly known as alcohol, ethanol gasoline is a new type of alternative energy formed by mixing ethanol and ordinary gasoline in a certain proportion of fuel processed from grain and various plant fibers. According to China's national standard, ethanol gasoline is made by blending 90% ordinary gasoline with 10% fuel ethanol.

1. Vehicle ethanol gasoline is easy to stratify when exposed to water. The problem of stratification is an important problem that needs to be solved in the promotion of ethanol gasoline for vehicles, including storage, transportation and practical use.

2. Vehicle ethanol gasoline has stronger volatility than ordinary unleaded gasoline. Therefore, when used as a power fuel for automobiles, ethanol gasoline for vehicles has stronger start-up properties, and at the same time, it is also harmful to the environment.

Effect. 3. The oxygen content of ethanol gasoline for vehicles is significantly higher than that of ordinary unleaded gasoline. This feature can effectively improve the power performance of ethanol gasoline for vehicles, and also make it better in economy and environmental protection than ordinary unleaded gasoline.

Compared with the traditional ordinary unleaded gasoline, automotive ethanol gasoline has the advantages of good fuel quality, high energy utilization rate and less environmental pollution, which is highlighted by its economic and environmental protection characteristics.

The state vigorously promotes this new high-quality automobile fuel, which is of great significance for the protection of the environment.

1. The ethanol in ethanol gasoline is a renewable resource, while gasoline is a non-renewable resource;

2. Ethanol gasoline is more environmentally friendly, which can reduce the emission of automobile exhaust, thereby reducing pollution, while the gas pollution emitted by gasoline is relatively serious;

3. The calorific value of ethanol is 60% of that of ordinary gasoline, so it is inferior to ordinary gasoline in terms of power and fuel economy;

4. Ethanol is a hydrophilic liquid, easy to miscible with water, different from gasoline, gasoline can be separated from water, and water is deposited at the bottom of the tank. Therefore, when using ethanol gasoline for the first time, the fuel tank should be checked first to see whether the moisture in the fuel tank exceeds the standard and affects the work of the engine.

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. Gasoline is a transparent liquid in appearance, and the main components are C5-C12 aliphatic hydrocarbons and naphthenic hydrocarbons, as well as 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.

Ethanol gasoline is more volatile than regular gasoline. And ethanol gasoline is not resistant to combustion.

Ethanol gasoline is an alternative energy source formed by mixing ethanol and ordinary gasoline in a certain proportion of fuel processed from grain and various plant fibers.

Ethanol gasoline is more environmentally friendly than petroleum gasoline, and the car burns out poorly.

Unleaded gasoline is a type of gasoline that is not refined, with tetraethyl lead added as an anti-seismic additive. Ethanol gasoline is a gasoline that adds a certain percentage of ethanol to the gasoline. Benefits of Ethanol Gasoline:

Ethanol is a renewable resource that can slightly alleviate the pressure of energy shortages; Good emissions, conducive to environmental protection; It has a high octane number and can be suitable for engines with high compression ratios, etc. Deficiencies of ethanol gasoline: slightly poor combustion performance, slightly insufficient power, and high cost; It is easy to absorb water, increase corrosion, and is not conducive to lubrication; It is easy to cause fuel system blockage; There is a certain strict process for mixing, and it is not recommended to mix it by yourself.

Due to the implementation of environmental protection policies, it is now difficult to find leaded gasoline at gas stations. The combustion exhaust of leaded gasoline is very harmful to the environment. Ethanol gasoline is more environmentally friendly and less dependent on oil.

If there is an awareness of environmental protection, **ethanol gasoline, but its combustion work will be slightly worse, and it is not as strong as ordinary gasoline. As for what kind of gasoline is good, the car manual will clearly state it (or the back of the fuel cap when it is opened). If the manual asks for 93, add 93

If you ask for 97, add 97. Don't upgrade artificially, that would be a waste, and you can't downgrade the use, which will cause damage to the vehicle. The vast majority of vehicles sold on the market are 93, and supercharged models or models with high compression ratios will require 97

If you can't be sure of the situation to add 97 is the safest, there will be no damage to the engine, but refueling should be careful not to change the label and mix, it is best to identify a brand of oil at the gas station.

The biggest difference between ethanol gasoline and pure gasoline is that 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 non-renewable, and the emission of gas pollution is more serious; In addition, there is a more obvious difference, the calorific value of ethanol is only 60% of that of conventional motor gasoline, so it will be worse than pure gasoline in terms of power and fuel economy.

Ethanol gasoline is mixed with a certain amount of denatured fuel ethanol, ethanol is a hydrophilic liquid, easy to mist with water, unlike gasoline, gasoline can be separated from water, and 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 crack the lead to prevent the ethanol gasoline from miscible with the sediment water that may exist at the bottom of the fuel tank, so that the moisture in the oil exceeds the standard and is lacking, affecting the normal operation of the engine. The fuel system of the car should be cleaned before using ethanol gasoline.

The differences between ethanol and gasoline are as follows:1. Different features:

Ethanol gasoline uses fuel ethanol as a gasoline additive, which is environmentally friendly, clean and renewable; Gasoline uses chemical substances such as MTBE as raw materials as gasoline additives, which is more polluting to the environment. 2.The evaporation potential is different:

Ethanol has a greater evaporation potential, twice as much as gasoline. 3.Different storage conditions:

Ethanol gasoline is volatile and not easy to store. After refueling, there is no need. After the expiration date, ethanol gasoline decomposes and stratification.

Gasoline is easy to store and does not volatilize even if it is not used for a long time. Gasoline is an alternative energy source made by mixing ethanol, a fuel processed from grain and various plant fibers, with regular gasoline in a certain proportion. It is made from a blend of 90% regular gasoline and 10% fuel ethanol.

Different gasoline components, such as straight-run gasoline components, catalytic cracking gasoline components, and catalytic reforming gasoline components obtained from petroleum refining, are refined and blended with high-octane components, mainly used as fuels for automobile ignition internal combustion engines.

Difference Between Ethanol Gasoline and Regular Gasoline:

1. The calorific value of ethanol gasoline and ordinary gasoline is different: 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.
