With the aim to improve the accuracy in transient A/F control for spark ignition engines, fuel film model was widely used. The traditional identification methods of the fuel film model were reviewed. To faster parameters identification process, a decoupling auto-identification method was presented. The result of simulation showed that the proposed method was valid. Finally, a theoretic two-equation algorithm, which could calculate the fuel film model parameters directly, was introduced.
