| Abstract: | The transient rotational speed of diesel engine was collected on-line by detection system, and then the data were analyzed by spectrum graphics. The diesel engine＇ s working condition was real - time detected, and the faults which led to bad power output were judged and analyzed. Moreover, the cylinder which had faults was confirmed. Actual application show that this system could diagnose the faults at the very beginning and therefore can avoid them becoming even worse. This technology offers references for diesel engine detection and maintenance. |
