Investigation of technical working fluid properties by photoacoustic spectroscopy

Jerzy Motylewski, B. Wiślicki, Kazimierz Krawczyk

Abstract

The goal of our investigations is to evaluate the photoacoustic spectroscopy technique a new tool for examination of technical working fluids properties. In the paper the last of spectrophotometric and photoacoustic measurements, concerning properties changes of oils and fuels after oxidation are presented. The photoacoustic experimental investigations of lubricating oils degradation in various conditions are outlined.
