Title (EN) CHARACTERIZING LUBRICANT OIL DEGRADATION USING FLUORESCENCE SIGNALS
(FR) CARACTÉRISATION DE DÉGRADATION D'HUILE LUBRIFIANTE À L'AIDE DE SIGNAUX DE FLUORESCENCE
Abstract:
(EN) Methods, systems, and apparatus to diagnose lubrication oil deterioration. In one aspect, a method includes irradiating a lubrication oil sample with a light beam to emit a light-induced fluorescence, detecting and processing the light-induced fluorescence signal to determine a temporal variation of a fluorescence intensity, identifying a steady state of the light -induced fluorescence signal, processing the temporal variation of the fluorescence intensity to determine a lubrication oil parameter, and correlating the oil parameter to a calibration curve to diagnose the lubrication oil deterioration.
(FR) L'invention concerne des procédés, des systèmes et un appareil pour diagnostiquer une détérioration d'huile lubrifiante. Dans un aspect, un procédé consiste à irradier un échantillon d'huile lubrifiante avec un faisceau lumineux pour émettre une fluorescence induite par la lumière, détecter et traiter le signal de fluorescence induite par la lumière afin de déterminer une variation temporelle d'une intensité de fluorescence, identifier un état stable du signal de fluorescence induite par la lumière, traiter la variation temporelle de l'intensité de fluorescence pour déterminer un paramètre d'huile lubrifiante, et mettre le paramètre d'huile en corrélation avec une courbe d'étalonnage pour diagnostiquer la détérioration d'huile lubrifiante.
