| Abstract: | This paper firstly introduces vibration testing results of an electronically-controlled two-stroke diesel engine on cylinder head, high pressure fuel pipe, high pressure fuel pump, engine side and turbocharger with different kinds of vibration sensors. Vibration signatures of these local vibration signals are revealed together with a reasonable explanation to the dual-peak on the indicator diagram of ME electronically-controlled two-stroke diesel engine. These results could lay a foundation for the further research work and application of vibration diagnosis technology into marine electronically-controlled two-stroke diesel engine. |
