What is the effect of adding isopropyl alcohol to gasoline?

Adding isopropanol to gasoline can play the following roles:

1. Increase the octane number of gasoline: Isopropanol is a substance with a high octane number, which can increase the octane number of gasoline, so that the anti-knock performance of gasoline is better, and the performance of the engine will be better.

2. Reduce tail gas emissions: Isopropanol can produce less harmful gases during combustion, such as carbon monoxide and nitrogen oxides, so it can reduce the pollution of vehicle exhaust emissions to the environment.

3. The calorific value of isopropanol is relatively high, which can increase the calorific value of the mixed fuel and improve the power output and combustion efficiency of the engine.

4. Isopropanol and gasoline have good solubility, which can improve the stability and fluidity of the mixed fuel to a certain extent.
