| Abstract: | This paper describes the structural features of circulating fuel oil system for a marine diesel engine and analysis the waveform characters of the pressure in the fuel oil system. Digital simulation on fuel injection process and relative deviation analysis of characteristic parameters were made for the system with different fuel viscosities and different fuel densities in the case of 12 typical faults. The internal relationships between the fuel waveform characters and the system fauls are revealed and the sensitivity of the characteristic parameters to the various faults are also given. |
