Abstract: Turbocharger operational condition is monitored using vibration and temperature sensors to project probable bearing failure. Baseline or nominal vibration levels and heat generation are established under conditions when bearing condition can be taken with confidence to be close to nominal. Departure in operating temperature and vibration at a threshold level from baseline operational condition is taken as an indication of probable failure.
