Problems solved by technology

[0002] With the continuous advancement of science and technology, the continuous development of the economy, the consumption of energy is also increasing. At present, the amount of oil consumed in the world is also increasing. Life, industry, etc. cannot do without oil. Of course, the exploitation of oil is also increasing It is becoming more and more difficult. Therefore, people are now researching new energy sources. Methanol gasoline has solved various problems caused by ordinary gasoline, and reduced environmental pollution and high energy consumption. However, methanol gasoline also has corresponding problems, such as poor stability. , water stratification, cold start difficulty, low calorific value, insufficient power, thermal air resistance, corrosion and swelling, etc. Methanol gasoline is composed of base gasoline, methanol and additives
