SYSTEM FOR IDENTIFYING THE LUBRICATING OIL IN A MACHINE

摘要

A method to determine when an oil change is required in a machine, said machine comprising a detector for detecting in situ a passive marker in a lubricating oil when the lubricating oil is in the machine, wherein the passive marker is an odourant molecule; and at least one sensor which indicates the state of the oil in the machine, said method comprising:
(i) using the detector to provide data about the identity of the lubricating oil in the machine;
(ii) using the at least one sensor to provide data indicating the state of the oil; and
(iii) utilising the data obtained in (i) and (ii) to determine when an oil change is required or to set values which can be used to determine when an oil change is required.
