| Abstract: | Research on diagnosing misfiring of engine has been carried out. Acoustic signal of engine for normal condition and misfiring condition were analyzed by utilizing Fourier transform, features of misfiring were extracted and tested by test instance. The results show that the misfiring fault can be judged exactly. A practicable analysis method for determining misfiring is put forward. |
