Abstract: Systems and methods for predicting engine performance are provided herein. A fluid sample having particles suspended therein is received from a first engine. A plurality of particles are extracted from the fluid sample. Features of the plurality of particles extracted from the fluid sample and features of particles of reference fluid samples from a plurality of reference engines are obtained. A plurality of correlation indices indicative of a level of correlation between the first engine and each one of the plurality of reference engines is determined. The correlation indices are compared to a threshold to determine a subset of the plurality of reference engines. Performance history for the engines in the subset is obtained. From the performance history, the first engine is determined as having a similarity in performance with the engines in the subset. An output is generated indicating a predicted performance for the first engine.

Abstract: Systems and methods for predicting a condition of an engine are described herein. A fluid sample having particles suspended therein is received from the engine. A plurality of particles are extracted from the fluid sample. A sample profile of the plurality of particles extracted from the fluid sample is obtained. A reference profile of particles of a reference fluid sample from a reference engine is obtained. The reference profile and the sample profile having particles identified based on size, aspect ratio and chemical composition. A correlation index between the sample profile and the reference profile is determined based on size and aspect ratio of the particles of the sample profile and the reference profile. A prediction that the engine has a known condition associated with the reference engine is generated from the correlation index. An output indicating the condition of the engine is generating based on the prediction.
