What are the advantages and disadvantages of ethanol gasoline? What do you think?

For ethanol gasoline, many people say that it does not burn sufficiently, is not good for the engine, and so on. So, is ethanol gasoline really bad? Let's start with the advantages and disadvantages of ethanol gasoline.

Let's talk about the advantages of ethanol gasoline. The octane number of ethanol gasoline is about 110, with strong power and good explosion-proof. Gasoline uses a high compression ratio, which improves the thermal efficiency of the engine and can increase the air intake of the engine through its strong evaporation capacity, thereby increasing the power of the engine.

<> environmentally friendly. Ethanol contains oxygen in its feedstock, which can effectively reduce emissions when fully combusted. Reduced carbon deposition.

Gasoline is uniquely flammable, and spark plugs, valves, and exhaust chambers are prone to carbon deposits. Ethanol can effectively eliminate carbon deposits in these areas, so car failures caused by carbon deposits can be effectively controlled. Fourth, ethanol resources can be fully utilized.

The feedstock of ethanol is a sugared crop and cellulose feedstock, which is a renewable energy source. As a result, we can not only make the best use of our resources, but also reduce our dependence on oil. Ethanol, commonly known as alcohol, ethanol gasoline is a new type of alternative energy source formed by mixing ethanol and ordinary gasoline in a certain proportion of denatured fuel processed from grain and various plant fibers.

According to China's national standard, ethanol gasoline is made from a mixture of 90% ordinary gasoline and 10% fuel ethanol.

The difference between ethanol gasoline and regular gasoline is the composition. The main components of regular gasoline include alkanes, olefins, and aromatics, which are all hydrocarbons, whereas ethanol is hydrocarbon, hydrogen, and oxygen. Ethanol gasoline is made from ethanol, which adds oxygen to the gasoline.

The result: less carbon and more oxygen, and a lower calorific value of gasoline. The calorific value of ethanol is about 60% of that of gasoline, and the total calorific value is reduced by about 4% at a 10% blending ratio.

In other words, a tank of gasoline can run 500 kilometers, but it can only run 480 kilometers with ethanol and gasoline, and its power performance is not as good as that of a gasoline car.

Do a detailed interpretation of the problem, I hope it will help you, if you still have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

The advantage of ethanol gasoline is that it can achieve the best fuel performance, high fuel efficiency and full power. The disadvantage is that it is relatively expensive, and the possibility of a car is relatively large, and I think ethanol gasoline must pay attention to safety when using it, and there must be a very good judgment.

The advantages of this gasoline are that the combustion time is relatively long, it is more environmentally friendly, it will not produce carbon dioxide, and the pollution to the air is relatively low. I think this gasoline is still better.

This gasoline is more volatile, and more environmentally friendly, it will have more benefits for the car, and the mileage is relatively long, but the value of this gasoline is relatively expensive, and it is easy to **, and the speed must be kept uniform, and the temperature can not be too high.

The advantage is that the anti-knock performance is very good, the ethanol content is very high, which can reduce the emission of exhaust gas, and can be more green and environmentally friendly. The disadvantage is that this gasoline is not good for the acceleration of the car, and it may cause metal corrosion. This may result in an increase in fuel consumption.

Advantages of ethanol gasoline: 1. Reduce harmful exhaust emissions; 2. Good power; 3. It can help the fuel system to clean itself and reduce carbon deposits; 4. Easy to use; 4. Abundant resources, etc. Cons:

1. Low calorific value; 2. It is easy to produce air resistance; 3. Corrosive metal; 4. Easy to stratify, etc.

1. The high oxygen content of ethanol gasoline for vehicles makes the fuel combustion more sufficient, and effectively reduces and reduces harmful exhaust emissions.

2. High ethanol octane number can improve the thermal efficiency and power of the engine by using high compression ratio, coupled with its large latent heat of evaporation, it can increase the air intake of the engine, thereby improving the power of the engine.

3. The use of ethanol gasoline can effectively eliminate the formation of carbon deposits in spark plugs, combustion chambers, valves, and exhaust pipe mufflers.

4. Ethanol is liquid at room temperature, easy to operate, easy to store, transport and use.

5. Ethanol has a good cleaning effect, which can effectively eliminate the precipitation and condensation of fuel impurities in the automobile fuel tank and oil circuit system.

6. The main raw material of ethanol is renewable resources and is abundant.

Disadvantages of ethanol gasoline:

1. Ethanol gasoline has low calorific content, and the mileage of a tank of oil is less.

2. The boiling point of ethanol is low, which is easy to produce gas resistance, which reduces the fuel supply or even interrupts the oil supply.

3. During the combustion process of ethanol, acetic acid will be produced, which has a corrosive effect on automobile metals.

4. Ethanol is easy to absorb water, and the water content of ethanol gasoline for vehicles exceeds the standard index, which is easy to separate the liquid phase, which affects the use.

Advantages of ethanol gasoline: reduced emissions, good power.

Reduced carbon deposit, easy to use, and self-cleaning of the fuel system. Of course, there are also disadvantages of this kind of gasoline, and the disadvantage of the main hand roll is the lack of ethanol gasoline for automobiles in terms of combustion value, power and corrosion resistance.

Merit. 1. The oxygen content of ethanol gasoline for vehicles is 35%, which makes the fuel combustion more sufficient.

2. High ethanol octane number (RON is 111), high compression ratio can be used to improve the thermal efficiency and power of the engine.

3. Due to the combustion characteristics of ethanol vehicles, it can effectively eliminate the formation of spark plugs, combustion chambers, valves, and exhaust pipe mufflers.

4. Ethanol is liquid at room temperature, easy to operate, easy to store, transport and use.

5. The ethanol added to the ethanol gasoline for vehicles is an organic solvent with excellent performance. It can effectively eliminate the precipitation and condensation of fuel impurities in the automobile fuel tank and oil circuit system.

Cons:1. The calorific value of ethanol is 60% of that of conventional motor gasoline.

2. The latent heat of vaporization of ethanol is large, and the evaporation temperature under the theoretical air-fuel ratio is greater than that of conventional gasoline.

3. Ethanol will produce acetic acid during combustion, which has a corrosive effect on automobile metals, especially copper.

4. Ethanol is an excellent solvent, which is easy to cause slight corrosion, dissolution, softening or cracking of automobile sealing rubber and other synthetic non-metallic materials. Brother.

5. Ethanol is easy to absorb water, and the water content of ethanol gasoline for vehicles exceeds the standard index, and it is easy to separate the liquid phase.

To put it simply, ethanol gasoline is beneficial to the country, and harmful to the people who use cars!

Judging from the driving performance of the car alone, it is obvious that pure gasoline will be betterAfter all, the latent heat of vaporization of ethanol is large, and the evaporation temperature under the theoretical air-fuel ratio is greater than that of conventional gasoline. It affects the formation and combustion rate of the mixture, resulting in the decline of the power, economy, and cold start of the car, which is not conducive to the acceleration of the car.

These are also the reasons why many car owners are not very interested in ethanol gasoline. However, the promotion of ethanol gasoline has become imperative, and what we can do as car owners is to learn more about ethanol gasoline voltaic knowledge in order to respond to all changes.

Ethanol gasoline for automobiles has the following advantages as a clean engine fuel oil:

1. High octane number and good anti-knock performance.

2. The oxygen content of ethanol is as high as that. Gasoline contains 10% ethanol, and the oxygen content can be reached.

3. The use of ethanol gasoline for vehicles can effectively reduce automobile exhaust emissions and improve the energy structure. Domestic studies have shown that E15 ethanol gasoline (with an ethanol content of 15% in gasoline) has lower carbon and carbon monoxide emissions than pure unleaded gasoline for vehicles, and carbon monoxide emissions have decreased by 30%.

4. The production of fuel ethanol is rich in resources and mature technology. When less than 10% is blended into gasoline, ethanol gasoline can be used directly without major changes to the engine of the car in use.

Gasoline will be rolled out across the country in the coming years. So, what are the advantages of ethanol gasoline potato bend? What are the advantages and benefits of not returning to ethanol gasoline? Let's talk about it now.

First, ethanol is a very good solvent and has a good cleaning effect. It has a good cleaning effect on the carbon deposits of the oil circuit and the fuel injector, and has its own cleaning function. Ethanol gasoline will have less carbon deposits than regular gasoline.

Second, ethanol gasoline burns more fully than regular gasoline. Carbon monoxide and hydrocarbons burn sufficiently, releasing more heat energy to compensate for the loss of power, resulting in a larger ignition advance angle. Smoother engine power delivery.

Third, China's oil reserves are scarce. The development of ethanol fuel can reduce dependence on imported oil and make the use of oil more environmentally friendly.
