ABSTRACT:
Herein disclosed is an oil degradation warning system for an engine equipped with a turbocharger. The system comprises first means for detecting the temperature of the engine oil in the turbocharger, second means for deriving a correction coefficient from informations issued from the first means; third means for multiplying a predetermined time increment by the correction coefficient to derive a modified time increment; fourth means for integrating the modified time increment to derive a time dependent oil degradation value; and fifth means for issuing a warning when the time dependent oil degradation value becomes equal to or larger than a predetermined value.
