The existent gum of five diesel samples under five different partial pressure of oxygen (PPO) (21%, 15%, 10%, 5%, 1%) was investigated by means of storage test method. The formation rate of existent gum (K) was established by the least square method. The influence of diesel composition and partial pressure of oxygen on K is examined. Multiple linear regression method and least square method were carried out to establish two models to predict the existent gum formation rate. Results indicate that existent gum increases linearly with the storage time during oxidation reaction. The reaction of olefin and oxygen is the main one of forming existent gum. The relationship between K and PPO is power function, mass fraction of olefin has a linear effect on K. F test results proved the correctness of the diesel oxidation model, which can be used to predict the diesel oxidation.
