Is unleaded petrol ethanol gasoline and do you use unleaded petrol or ethanol petrol?

I use ethanol gasoline, because ethanol gasoline has fewer additives, and ethanol is easy to play in the process of use, which will have less impact on air pollution, while unleaded gasoline is more efficient, but because of its higher production cost, oil prices will be higher, plus unleaded gasoline is more serious in air pollution, so I think ethanol gasoline is better.

Unleaded gasoline is not ethanol gasoline, I use ethanol gasoline, and ethanol gasoline has relatively low emission pollution.

Of course not, we usually use unleaded gasoline, 52 gasoline, 95 gasoline, 98 gasoline, most of them are unleaded gasoline.

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.

The biggest difference is that unleaded gasoline is non-renewable and emits serious gas pollution, while 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.

Unleaded gasoline contains only trace amounts of lead, which is generally one percent per litre of gasoline. It has an octane rating of 95, which is slightly lower than the octane rating (97) of other existing grades of leaded gasoline. The use of unleaded gasoline can effectively control harmful substances in automobile exhaust gases, reduce pollution such as hydrocarbons (smoke caused by HC), carbon monoxide (CO toxicity) and nitrogen oxides (NOx form acid rain).

The most effective and easiest way to reduce blowdown is to install a catalytic converter in the exhaust system.

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. Ethanol is a renewable energy source and is produced by fermentation of sorghum, corn, potatoes, etc.

It does not affect the driving performance of the car and also reduces the emission of harmful gases. As a new type of clean fuel, ethanol gasoline is the focus of renewable energy development in the world.

What is the difference between unleaded petrol and ethanol petrol? What is the difference between unleaded petrol and ethanol petrol? Here are the differences between unleaded gasoline and ethanol gasoline:

1. Different additives: gasoline is a fraction collected from petroleum, which is hydrocarbons (mainly alkanes, containing a small amount of olefins), which itself is free of lead, and gasoline is unstable and easy to use, so the original gasoline is added with a lead-containing explosion-proof agent. 2. Different degrees of pollution:

Exhaust from the exhaust pipe after gasoline combustion can cause a certain amount of pollution. Today's gasoline is basically changed to unleaded explosion-proof agents, that is, unleaded gasoline. (90% of the products on the market are basically lead-free); Ethanol gasoline is a certain amount of ethanol mixed with gasoline, 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). 2019

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.Ethanol gasoline has a lower calorific value of combustion than gasoline: therefore, using ethanol gasoline will feel a decrease in the power of the car.
