Model for predicting volatility of fuel blends

The volatility of both gasoline and oxygenated fuel blends was simulated by major-fuel-component models; the effect of blending oxygenate into gasoline of fuel volatility was also investigated. The simulation results show that this model can reflect the nonlinear phenomena due to the polar ends of oxygenate molecules; blending oxygenate into gasoline will effectively improve fuel volatility and this improvement was found to have direct proportion to the amount of oxygenate blending into gasoline.
