Is ethanol gasoline better or pure gasoline? What kind of oil will not damage the car?

From the driving performance of the car alone, it is obvious that pure gasoline will be better. After all, the latent heat of vaporization of ethanol is large, and the vaporization temperature under the theoretical air-fuel ratio is higher than that of conventional gasoline. It affects the formation of mixture and combustion speed, which leads to the decline of automobile power, economy and cold start, which is not conducive to automobile acceleration.

These are also the reasons why many car owners are not interested in ethanol gasoline. However, it is imperative to popularize ethanol gasoline. As car owners, what we can do is to know more about the knowledge of ethanol gasoline, so as to keep constant and change.

As a clean engine fuel, vehicle ethanol gasoline has the following advantages:

1, high octane number and good antiknock performance.

2. The oxygen content of ethanol is as high as 34.7%. When gasoline contains 10% ethanol, the oxygen content can reach 3.5%.

3. The use of ethanol gasoline for vehicles can effectively reduce automobile exhaust emissions and improve energy structure. Domestic research shows that compared with unleaded gasoline, E 15 ethanol gasoline (ethanol content in gasoline is 15%) reduces carbon and hydrocarbon emissions by 16.2% and carbon monoxide emissions by 30%.

4. Fuel ethanol production is rich in resources and mature in technology. When the blending ratio of gasoline is less than 10%, ethanol gasoline can be directly used without any major changes to the existing automobile engine.
