What is the understanding of gasoline and ethanol gasoline?

Ethanol, commonly known as alcohol, ethanol gasoline is a fuel processed from grain and various plant fibers, ethanol and ordinary gasoline are mixed in a certain proportion to form an alternative energy source. According to China's national standard, ethanol gasoline is made by blending 90% ordinary gasoline with 10% fuel ethanol. It can effectively improve the performance and quality of oil products, and reduce the emission of major pollutants such as carbon monoxide and hydrocarbons.

It does not affect the driving performance of the car and also reduces the emission of harmful gases. ‍‍

The denatured fuel ethanol in automotive ethanol gasoline is an organic solvent with excellent performance, which can effectively eliminate the impurities precipitated and condensed in the fuel tank and oil circuit system, has a good oil channel dredging effect, and can reduce the cost of purchasing other additives for cleaning and dredging the oil circuit;

China's vehicle ethanol gasoline refers to the gasoline used as gasoline vehicle fuel after adding 10 denatured fuel ethanol to the gasoline component oil according to the volume mixing ratio. Professional definition: a certain amount of denatured fuel ethanol is added to a liquid hydrocarbon without adding oxygenates and then used as fuel for ignition internal combustion engines, and the amount of denatured fuel ethanol added is 10, referred to as E10.

No water can enter the oil supply system. If there is moisture in the tank, it is miscible with denatured fuel ethanol and will affect the normal operation of the engine.

There must be no dirt inside the tank. Ethanol gasoline has a strong cleaning effect, which may clean off the dirt and cause the parts to be blocked.

Vehicle ethanol gasoline refers to a new type of clean vehicle fuel blended by adding a certain proportion (10% of China's regulations) of denatured fuel ethanol to the gasoline component oil.

It increases the oxygen content in gasoline, makes the combustion more sufficient, and completely and effectively reduces the emission of harmful substances in the exhaust gas;

I don't know what the difference between adding ordinary 92 and clean fuel is on the bright side, I just know that what I added in Shenzhen this year is basically fake oil.

It takes 10 seconds to run at high speed to 90 and then to 100, and to accelerate to 120 depends on steep slopes. A year ago, it only took about 10 seconds to accelerate to 130 with the same addition of 92, 90, and I added oil twice in Hunan on this National Day, once at the level of a year ago, and once at the level of oil products in Shenzhen now.

At present, the use of ethanol gasoline in the country includes the three northeastern provinces, Henan Province, Anhui Province, Shijiazhuang, Baoding, Cangzhou, Hengshui and Handan in Hebei Province, as well as some cities in Hubei Province, northern Jiangsu and southeastern Shandong.

In a nutshell, one drop and three increases. Power decreases, fuel consumption increases, pollution increases, and expenses increase.

Effectively eliminate the formation of carbon deposits in spark plugs, valves, piston tops, exhaust pipes, and mufflers, and can extend the service life of major components.

For the sake of environmental protection and the use of cars, can the ethanol gasoline content be changed to 5%.

Seven liters of fuel is consumed for 100 km, and if ethanol gasoline is added, 8 liters for 100 km, at the same distance, fuel consumption increases, and pollution does not decrease, but increases!

The difference between ethanol gasoline and gasoline is that the performance is different, the ethanol in ethanol gasoline is a renewable resource, which is made by fermentation of sorghum, corn, potatoes, etc., which is more environmentally friendly, gasoline is non-renewable, and the emission of gas pollution is more serious.

Ethanol gasoline is a kind of alternative energy source that is processed from grain and various plant fibers, and ethanol and ordinary gasoline are mixed in a certain proportion. Since ethanol is an organic solvent, organic acids will be produced during production, storage and combustion, which is easy to corrode and wear parts. It is necessary to clean the fuel system and fuel tank, carry out anti-corrosion treatment on the plastic seals of the car, and replace some rubber materials, such as replacing the hose with butadiene rubber and replacing the seals with fluorine-containing rubber.

Gasoline classification

The ethanol in ethanol gasoline is not quite the same as the alcohol we drink in our daily life or the ethanol in industrial alcohol, it is a kind of ethanol with a concentration of more than that, which is more like a fuel ethanol. Since the combustion energy density of ethanol is not as good as that of gasoline, if the combustion is done with the same power, the amount of ethanol gasoline consumed is bound to be more than that of gasoline, but it is still within the acceptable range.

Ethanol is a solvent that has a certain cleaning effect, so ethanol gasoline also has a cleaning and scouring effect on some of the accumulated impurities in the oil circuit, and will enter the engine with impurities, which has certain hazards and damages, especially for some old cars, which will increase the probability of failure of Yanliang vehicles.

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, which can be said to be twice that of gasoline, which can improve the thermal efficiency of the engine and the favorable factors for cooling the engine.

3. Different advantages: lower calorific value, compared with ordinary gasoline, the calorific value of ethanol gasoline is only 61%, and more fuel is required to drive the same distance than ordinary fuel, although the calorific value is much smaller than gasoline, theoretically the calorific value of the mixture is very close to that of gasoline, so ethanol can be used as gasoline engine fuel.

4. Different disadvantages: easy to produce gas resistance, if ethanol gasoline is used, it is easy to produce gas resistance under the normal working temperature of the vehicle engine, because the boiling point of ethanol is lower than that of ordinary gasoline, only about 78 degrees Celsius, which makes the fuel supply easy to reduce, and even cut off the oil halfway.

First, 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 ethanol made of grain and various plant fibers.

Second, from the perspective of environmental protection, ethanol gasoline burns in the car at the same time, the release of toxic gases is much less than unleaded gasoline, so the harm to human beings is small.

Third, in addition, the raw material of ethanol is the grain crop corn, and now the demand for gasoline is strong, so ethanol gasoline can drive the development of agriculture, which ordinary gasoline can not do.

Fourth, the last point is that ethanol gasoline is more volatile, as a fuel for automobiles, the starting performance is better than ordinary gasoline.

Ethanol is often referred to as alcohol. It will turn ethanol gasoline into deformed fuel. Ethanol and gasoline are mixed in a certain proportion to form a closed motor fuel.

In fact, 10% lead biofuel ethanol is added to gasoline. As long as there is an E letter behind the gasoline label, it is ethanol gasoline. Difference between ethanol gasoline and gasoline 1, ethanol in ethanol gasoline is a renewable energy source, while gasoline is not a renewable energy source; 2. Ethanol gasoline is more environmentally friendly, which can reduce the emission of automobile exhaust gas, thereby reducing environmental pollution, while the environmental pollution of exhaust gas discharged by gasoline is relatively serious; 3. The calorific value of ethanol is 60% of that of general gasoline, so it is not as good as general gasoline in terms of driving force and fuel rationality; 4. Ethanol is an absorbent liquid state, which is easy to missolve with water, which is different from gasoline, which can be separated from water, and the water accumulates at the bottom of the automobile fuel tank.

Therefore, when ethanol gasoline is applied for the first time, it is necessary to check the automobile fuel tank first to see whether the moisture in the automobile fuel tank exceeds the standard and endangers the work of the automobile engine. Now ethanol gasoline is still in the pilot stage, the current ** is not very fixed, and there are also differences in oil prices in different regions, but one thing is for sure, the ** of ethanol gasoline will be cheaper than ordinary gasoline, depending on the local pricing standards. According to the above introduction, ethanol gasoline is not widely used now, but with this technology, the economic fuel performance of using it will be worse, and of course it will be cheaper than ordinary fuel.
