Abstract : This is the final report of a study to determine whether computerized infrared spectroscopy is a feasible technique for oil condition monitoring. The study addresses the major factors that influence the performance of a lubricant in service and demonstrate that these factors may be monitored with infrared spectroscopy. The study identifies specific regions and peaks within the infrared spectra to be monitored in a routine oil condition monitoring program and proposes abnormal threshold for quantitative measures of these regions and peaks. Evaluation criteria for five Army combat and tactical vehicle engines and one Air Force administrative engine are developed. Further the study recommends a field test of the infrared methodology at a single Army installation. Objective 1. Evaluate the effectiveness of the Perkin-Elmer Model 1330, Computerized Infrared Spectrophotometer, as a used oil condition monitoring device. Objective 2. Develop an improved oil condition monitoring methodology based on computerized infrared spectrophotometry. Originator-supplied keywords include: Infrared Spectroscopy, transmittance, absorbance, integrated area, peak heights, hydroxyl, oxidation, carbohydrates, nitration, sulfation, fuel dilution, total acid number, total solids, viscosity, carbon loading, graphs.
