What is the purpose of advocating the use of ethanol gasoline

It mainly plays a role in removing carbon and reducing air pollution. Reduce costs.

Lower emissions and lower production costs.

Ethanol gasoline is more environmentally friendly to use, what are the characteristics of this gasoline? As we all know, we are currently familiar with the categories of gasoline labels, mainly 92 and 95, which are air emissions, which will cause certain pollution in the air. In order to reduce pollution, a new gasoline has also appeared in the public eye, namely ethanol gasoline.

Currently, most cities use ethanol gasoline, and then, today we will see what is ethanol gasoline? Can it be used with regular gasoline?

First, let's take a look at ethanol gasoline. In fact, ethanol is the familiar alcohol, ethanol gasoline is a new fuel blended with ethanol, a plant fiber processing fuel, of course, this blending requires a certain process, not just stirring together, and ethanol gasoline is more environmentally friendly than regular gasoline, it can reduce harmful substances in the air and the cost is relatively low.

Secondly, let's see if ethanol gasoline is mixed with regular gasoline? During the daily car, the 4S shop salesman will recommend us to use the same gasoline, because the vehicle engine has a certain amount of mill, which is also a kind of grinding between gasoline, constantly changing the label of gasoline, or mixing ethanol gasoline with ordinary gasoline, which is very large for the vehicle engine, such as high fuel consumption, fault light alarm, etc., which can easily affect the performance of the vehicle. The massive promotion of ethanol gasoline has been explained:

Ethanol gasoline is good, fuel consumption is not reduced, the car is not harmed, safe and environmentally friendly. However, there are a lot of riders who are worried: my car is a new energy car, will it damage the engine after using ethanol gasoline?

After using ethanol gasoline, will oil separation affect the life of the engine? How do you protect your engine?

First of all, from the influence of the engine, ethanol gasoline adds fuel ethanol to regular gasoline. It is a new type of energy formed in proportion, ethanol is a well-known alcohol, and friends who like to drink alcohol have hydrophilicity, once there is water or ethanol gasoline in the fuel tank, it will cause the fuel tank to be turbid, the water content is large, resulting in the engine is not easy to ignite, engine rust or other sealing materials. Of course, ethanol gasoline is relatively adequate due to its oxygen content and better anti-riot performance, but ethanol gasoline is a mixture of ethanol, a plant fiber processing fuel, and regular gasoline, so the dynamic performance of vehicles using ethanol gasoline will also decline.

All in all, ethanol gasoline is just a fuel and is advantageous, the key is how we accept it. In addition, as in our article, it is better for the owner not to use ethanol gasoline with regular gasoline to avoid unnecessary trouble.

The biggest advantage is that the exhaust gas discharged after use will not cause too much pollution, and it also has a certain purification effect on the environment, which can reduce the emission of exhaust gas.

The use of ethanol gasoline without engine modification on the premise of the power performance is basically unchanged. The compounds emitted by the exhaust gas are reduced by more than 30% on average, which effectively reduces and reduces harmful exhaust emissions. The combustion characteristics of automotive ethanol gasoline effectively eliminate the formation of carbon deposits in spark plugs, combustion chambers, valves, exhaust pipes and mufflers, avoid failures caused by carbon deposits, and prolong the service life of components.

Ethanol has a large latent heat of evaporation, which can increase the air intake of the engine, thereby improving the power of the engine.

Ethanol gasoline is more environmentally friendly than regular gasoline, it can reduce harmful substances in the air and the cost is relatively low, ethanol gasoline is more environmentally friendly than regular gasoline, it can reduce harmful substances in the air at a relatively low cost.

This kind of gasoline can enrich our lives, and make our lives better, and it will also be particularly environmentally friendly, tasteless, and protect the earth.

This gasoline is not only environmentally friendly, but also can improve fuel economy by 30% and help reduce greenhouse gas emissions by 20%, which can reduce emissions, good power performance, reduce carbon deposits, and be easy to use.

It does not have any pollution to the environment, ** is not very high, this oil is very environmentally friendly, and the use rate is also very high.

When d gasoline burns, there is still の generated.

Answer: CD analysis: ethanol can effectively improve the performance and quality of oil, reduce carbon monoxide, hydrocarbons and other major pollutant emissions Fermentation method of ethanol and ethylene directly reacts with water, ethanol gasoline will also produce pollution, and it will produce sulfur gas and carbon monoxide in the case of incomplete combustion, which are polluting gases

Answer: a. Ethanol can effectively improve the performance and quality of oil products, reduce the emission of major pollutants such as carbon monoxide and hydrocarbons It does not affect the driving performance of the car, but also reduces the emission of harmful gases, and is a clean energy to improve the environment Therefore, the description of a is correct;

b. Fermentation method of ethanol is developed on the basis of liquor, and the raw materials of fermentation method can be starch-containing agricultural products, such as cereals, potatoes or wild god shed plant fruits; Waste molasses from sugar mills can also be used; Or use cellulose-containing wood chips, plant stems, etc. Ethylene direct hydration method, that is, under the conditions of heating, pressure and the presence of catalysts, ethylene reacts directly with water to produce ethanol, so the description is correct;

c. Ethanol gasoline is made by blending 90% ordinary gasoline with 10% fuel and high ethanol, so it can be seen that ethanol gasoline is a mixture, so the description of C is incorrect;

d. From option A, it can be seen that ethanol gasoline can reduce air pollution, but ethanol gasoline will produce pollution with the ruler, and it will produce sulfur-containing gas and carbon monoxide in the case of incomplete combustion, which are polluting gases, rather than gasoline does not contain sulfur and nitrogen, so the option is wrong

Therefore, the use of ethanol gasoline for vehicles can not only save petroleum resources and effectively reduce the pollution of automobile exhaust, but also promote agricultural production
