Abstract:
Systems and methods are provided for determining an exposure temperature in an engine. One or more particles filtered from lubrication fluid of an engine may be analyzed. The chemical composition of filtered particles may be compared to reference data which includes a relationship between chemical composition and exposure temperature. An estimate of the exposure temperature may be determined. An output may be generated based on the exposure temperature.
