After inspection, engineers found that there were large particles of carbon deposition in combustion chamber (as shown in Figure 7).
Secondly, Signal frequency was mainly concentrated in the power frequency and its multiple frequency, there was no frequency corresponding to the rotational speed. meanwhile, it was found that there were large carbon particles after engineers taking apart the engine.The abnormal ones were carbon deposition from fuel spray nozzle.
