| Abstract: | Through measuring the voltage variation of the speed sensor on the WD615 diesel engine,the instantaneous speed signal can be gained and is processed with the sliding mean method of digital filter.Finally,the cut-off fault can be diagnosed and the uniformity of cylinder and power can be estimated under the condition of disassembling the engine.The experiment on the WD615 diesel engine proves that the method is credible,fast and practical. |
