Case Study #2-Missing Parts in a fuel pump

Following a periodic engine analysis activity, it was
immediately noted by the analyst that Cylinder #2 had a
peak firing pressure approximately 134 PSI lower than the
engine average, the peak firing pressure was early ~3
degrees and exhaust temperatures were approximately
180 degrees F lower then engine average (Fig. 30).

The fuel pump ultrasonic data (Fig. 31) identified a
mechanical anomaly in the fuel pump.
