Last year, the official website of the National Energy Administration announced that the promotion of ethanol gasoline will be accelerated and expanded, and full coverage will be achieved as soon as 2020. This also means that in the next 2 years, we will gradually start to use E10 ethanol gasoline with 10% ethanol. In fact, E10 ethanol gasoline has already started pilot work as early as 2002.
What is ethanol gasoline? According to my country’s national standards, ethanol gasoline is made by blending 90% ordinary gasoline and 10% fuel ethanol. 10% ethanol generally uses corn as raw material. The reason why the country popularizes and promotes ethanol gasoline is mainly due to the environmental protection needs and the increase of domestic demand and the increase of the demand for grain (corn), because my country has a bumper harvest of grain every year, and the accumulation of old grain is relatively large. I believe everyone has seen a lot of related news. ! In addition, my country’s kerosene resources are relatively scarce, and the development of ethanol fuel can reduce the dependence on imported kerosene. Ethanol itself is a kind of fuel. After mixing a certain amount of ethanol, it can save a lot of kerosene resources compared with pure gasoline under the same quality. Therefore, bioethanol is considered as an alternative product that can replace fossil power.
Does ethanol gasoline have a big impact on cars? At present, most cars on the market can use ethanol gasoline. Generally speaking, the fuel consumption of ethanol gasoline is slightly higher than that of pure gasoline, but the octane number is slightly higher and the anti-knock performance is slightly better. Compared with ordinary gasoline, ethanol indirectly improves thermal efficiency due to its high oxygen content and more complete combustion. However, it is also because of the characteristics of ethanol that are different from gasoline. Compared with ordinary gasoline, ethanol gasoline has better power at high speeds. The power is even worse at low revs. In fact, ethanol gasoline has been used in Jilin for a long time. Objectively speaking, it has an impact on the vehicle, but it is not obvious, so you don’t have to worry!
Besides China, which other countries are promoting ethanol gasoline? At present, the most successful country in promoting ethanol gasoline is Brazil. Brazil is not only the second largest ethanol fuel producer in the world, but also the most successful country in promoting ethanol gasoline in the world. As early as 1977, Brazil was implementing ethanol gasoline. Now, all the gas stations in Brazil do not have pure gasoline to add, and all the ethanol gasoline with content ranging from 18% to 25% is sold.
