What is the difference between unleaded gasoline and ethanol gasoline, and can you add both types of

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.

If you have a choice, of course, it is better to choose unleaded gasoline, occasionally choose ethanol gasoline can clean the engine carbon accumulation, ethanol gasoline does have this advantage, a friend drove an old car for 8 years, adding ethanol gasoline because of carbon accumulation, the oil pipe is blocked, and the oil circuit can not be cleaned. Since ethanol gasoline is an excellent solvent that has a good cleaning effect on colloids and carbon accumulation in the oil circuit, it is best to clean the oil circuit before adding more carbon accumulation to the car.

The biggest disadvantage of ethanol gasoline is that it is slightly underpowered. The same car with ethanol gasoline climbs as well as gasoline. The mileage is also slightly lower than that of gasoline.

However, unlike some people say, a box of oil runs 100 kilometers less, in fact, there is so much less. The advantage of lead-free oil is that the energy produced when burned is relatively large, which gives the car a strong sense of power. However, the disadvantage is that there is too much residue after combustion, which will lead to a large amount of residue in the car oil pipe, mailbox, and engine, and the emission will cause serious pollution to the environment.

The main reason is that some additives and some residues from the combustion of ** itself are added during the refining process. Of course, the average person loves this oil because it is flame resistant.

Why the use of ethanol oil is advocated is mainly for environmental protection. Of course, at least that's what the above propaganda is. Ethanol oil is generally added with about 10% ethanol, which saves about 10% of fuel.

For energy saving, these figures are really very large, and they also reduce environmental pollution, which is really a double win. Of course, it can't be cheap. You don't have a choice.

Some people say that to change ethanol gasoline, you need to clean the oil duct. I don't think it's necessary. Don't be so mysterious.

The main reason for unleaded gasoline is that the ingredients in it are different, and the car is very fast in the process of running, and the second ethanol gasoline, such gasoline ** will be slightly more expensive, so few people use cars, and it is best to use unleaded gasoline.

Their combustion calorific value is not the same, the power provided to the car is different, the fuel consumption is different, the exhaust emission is not the same, ** is different, the combustion calorific value of unleaded gasoline is relatively high, so the power provided is relatively sufficient. Both can be added, and the two have different effects on the car.

Unleaded gasoline mainly adds an anti-seismic and explosion-proof additive in the refining process, while ethanol gasoline adds some ethanol to the gasoline, which can reduce the consumption of oil, and this oil can also reduce the pollution of exhaust gases; Both gasoline cars can be used.

First, the nature is different.

1. Properties of ethanol gasoline: In the special gasoline component oil (blended oil produced by oil refineries or petrochemical plants for blending ethanol gasoline for vehicles) without MTBE oxygenated additives, a certain proportion (tentatively set at 10% in China) of denatured fuel ethanol is added according to the volume ratio.

2. Properties of unleaded gasoline: Gasoline with lead content below is not added as an anti-seismic explosion additive in the refining process.

Second, the characteristics are different.

1. Characteristics of ethanol gasoline: the low calorific value of ethanol is equivalent to that of gasoline and diesel. However, in terms of relative energy consumption, its thermal efficiency is not lower than that of gasoline and diesel; Ethanol has a high octane number, is a good substitute fuel for gasoline engines, and is a good additive to increase the octane number of gasoline.

However, its cetane number is very low, making it difficult to apply to compression-ignition engines.

2. Characteristics of unleaded gasoline: In addition to unleaded gasoline, unleaded gasoline may still emit gas, particulate matter and condensate when burned, and the harm to human health still exists. Among them, the gases are mainly carbon monoxide, hydrocarbons, and nitrogen oxides.

Hello dear( °u° ) I've seen your problem, wait a minute.

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.

Questions. How to blend ethanol gasoline?

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.

Ethanol gasoline: conventional gasoline plus a certain amount of ethanol; The ethanol gasoline commonly used in China contains 10% ethanol, and generally does not need to make any additional improvements to the fuel system, however, it is recommended to flush with ethanol gasoline and add new oil to avoid clogging.

Benefits of ethanol gasoline: Ethanol is a renewable resource that can slightly alleviate the pressure of energy shortages; Good emissions, conducive to environmental protection; High octane number, can be suitable for high compression ratio engine, 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.

Moreover, it is recommended not to mix with ordinary unleaded gasoline as much as possible, there are certain professional factors, and it is not recommended to mix it by yourself.

Compared with the technical requirements of GB17930-1999 unleaded gasoline for automobiles, the ethanol gasoline standard for automobiles has the following characteristics: (1) The ethanol content is increased. The ethanol content is required to be in the range, and other inclusions are not allowed to be artificially added, but higher alcohols as co-solvents are allowed.

2) The mechanical impurities and moisture in the original unleaded gasoline for vehicles. As early as the 20s of the 20th century, the use of ethanol gasoline began in Brazil. Due to the lack of petroleum resources in Brazil, but the abundance of sugarcane, a complete set of technologies for the production of sucrose and alcohol from sugarcane has been formed.

Currently, Brazil is the world's most used ethanol gasoline with an ethanol content of 20. The United States is another large consumer of fuel ethanol in the world. Ethanol gasoline was first introduced in the Nebraska region in the 30s of the 20th century.

In 1978, 10-ethanol gasoline (E10 gasoline) was used on a large scale in Nebraska, and since then, the U.S. federal ** has implemented tax breaks on E10 gasoline, and fuel ethanol production has increased rapidly from 30,000 tons in 1979 to 2.69 million tons in 1990. In 2000, U.S. fuel ethanol production reached 5 million tons. As MTBE use decreases and eventually bans in the U.S., fuel ethanol will be the best oxygenated alternative to MTBE.

It is expected that by 2004 the United States demand for fuel ethanol will reach 10 million tons.

There is no difference, ethanol gasoline only contains 10% ethanol, and the method or additive to improve knock resistance is not lead, and the additives are the same.

Ethanol gasoline is 10% alcohol 90% gasoline. It's been years since we switched to ethanol gasoline, and my car has been refueled for years. Not because of anything else, only ethanol gasoline.

In the past few years, I haven't felt anything abnormal about the car, and I haven't felt any difference in fuel consumption. In other words, the sales of 10% alcohol gasoline are as unpleasant as the ** of pure gasoline, but there is nothing left, don't worry about adding it boldly. The calorific value of fuel ethanol is unleaded, and mixing gasoline at a ratio of 10% will cause the overall calorific value of the fuel to decrease by about %.

The emissions generated by the increase in fuel consumption are reduced by 10% after the mixture, so it is possible to reduce emissions. It's just that as a car user, we should spend more money for environmental protection, but that goes back to the topic at the beginning. Why should it be "Liaosulu, Henan, Anhui, Heiji" provincial and district car users to bear the responsibility of national air purification?

If car fuel is also competing for the otherwise tight feed grain, it is an inconceivable act to put the cart before the horse. Especially in the period of low prices, it is a very undesirable wasteful behavior. Therefore, I believe that the current pandemic is far from being eliminated.

A large amount of ethanol is needed to prevent and control the virus, international energy demand is declining, oil prices are low, and food security problems are becoming increasingly prominent. In the reality that domestic oil refining enterprises are losing serious losses, we should actively adjust the embarrassing policies for the production and promotion of ethanol and gasoline, and abolish the policies and strategies of labor, people, and money as soon as possible.

The gasoline we usually use is unleaded. It is a substance extracted from petroleum. It has the advantages of flame resistance, high durability, high combustion value and good power.

To put it bluntly, ethanol gasoline is an alternative to gasoline and is a mixture of ethanol and gasoline. Its combustion value is low. During the use of the vehicle, the most common manifestations are the idle jitter and insufficient power of the vehicle.

Ethanol is alcohol, perishable, and soluble in water. It is easy to form delamination after a long time. In addition, the same quantity and durability as unleaded gasoline are also different.

As we usually say, 92 petrol is much softer than 98. It has different seismic values, and the durability is a bit low, supported by other factors.

Overall, although gasoline is not very environmentally friendly than ethanol gasoline, it has a strong gasoline power. At the same amount, gasoline has a higher durability, so unleaded gasoline is better. As far as I know, ethanol gasoline is not put into service at high altitudes, probably due to insufficient combustion, poor power, low durability.

Unleaded gasoline is a type of gasoline that is not added to tetraethyl lead as a shock-resistant** additive during the refining process. Unleaded gasoline contains only trace amounts of lead from **, generally 1% per liter of gasoline. Unleaded gasoline is not harmless gasoline, gasoline is unleaded, which fundamentally solves the problem of lead pollution in automobile exhaust.

In addition to unleaded, unleaded gasoline can still emit gases, particulate matter and condensate when burned, and the harm to human health still exists.

**No, the combustion value of ethanol gasoline is lower than that of cars, the additives are not the same, gasoline is a fraction extracted from petroleum, it is a hydrocarbon, the degree of environmental pollution is different, and both cars can be added.

The main difference is that the additional treatment of gasoline is different, one is to refine lead, the other is to add ethanol, and both oil cars can be added.

Unleaded petrol is a liquid fuel made from natural petroleum**.

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

Both types of oil cars can be added.

Gasoline is a fraction collected from petroleum, which is a hydrocarbon (composed of alkanes, containing a small amount of olefins), which itself is lead-free, and gasoline is unstable and easy to **, so the original gasoline is added with a lead-containing anti-explosion agent.

Exhaust from the exhaust pipe after gasoline combustion can cause a certain amount of pollution. Today's gasoline is basically changed to unleaded anti-explosion agent, that is to say, unleaded gasoline. (90% of the products on the market are basically lead-free).

Ethanol gasoline, on the other hand, is mixed with a certain amount of ethanol in gasoline, which is about 15%. The purpose of this is that ethanol is a renewable energy source, and it is cheaper, so it is more economical to use, and such gasoline is called ethanol gasoline. (It is emphasized here that the essence of ethanol gasoline is still gasoline, but it contains ethanol).

Benefits of ethanol gasoline: Ethanol is a renewable resource that can slightly alleviate the pressure of energy shortages; Good emissions, conducive to environmental protection; High octane number, can be suitable for high compression ratio engine, 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.

Buy a car, use a car, maintain a car, repair a car, and listen to Chen Gong talk about cars.

Difference Between Ethanol Gasoline and Unleaded Gasoline:

1. Difference: Ethanol gasoline is generally cheaper, after all, the proportion of gasoline is reduced, and this low-cost alcohol replaces part of gasoline.

2. The calorific value of combustion of ethanol gasoline is lower than that of gasoline: therefore, using ethanol gasoline will feel that the power of the car decreases.

3. The same tank of oil can run different kilometers: adding a tank of unleaded gasoline can run 600 kilometers, and a tank of ethanol gasoline can only run 570 kilometers.

Advantages of each:

Advantages of ethanol gasoline:

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

2. The oxygen content of ethanol is as high. 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.

Advantages of unleaded petrol:

If the car uses unleaded gasoline for a long time, it can effectively control the harmful substances in the automobile exhaust gas and reduce the generation of harmful gases such as hydrocarbons, carbon monoxide, and nitrogen oxides. In addition, compared with leaded gasoline, unleaded gasoline has a lower impact on the three-way catalytic converter and can maintain the working condition of the car.

It is worth mentioning that in the past few years, ethanol gasoline appeared on the market, which is made by blending 90% ordinary gasoline and 10% ethanol. Compared with unleaded gasoline, the calorific value is higher, the power after use is stronger, and the fuel consumption is lower. However, ethanol gasoline is better in terms of environmental protection, has a strong cleaning ability, is also relatively cheap, and has a good cost performance.

Therefore, if you want to save some fuel costs, you can also consider using ethanol gasoline.

Unleaded petrol is not harmless. In order to reduce the degree of air pollution and improve the health level of the people, since 2000, unleaded gasoline has been promoted nationwide, and the unleaded gasoline has been realized, which has fundamentally solved the problem of lead pollution in automobile exhaust.
