| Abstract: | The vibration signal of the STEYR diesel engines has analyzed based on wavelet theory, and a feasible means is put forward for the signal de-noising, which has been confirmed to be efficiency and accuracy by the experimentation data. The means provides a feasible technique support for fault Diagnoses of STEYR diesel engines. |
