Abstract

This paper describes the development of a pressurized differential scanning calorimeter (PDSC) method for the characterization of the deposit forming tendencies of engine lubricants and their components. Test repeatability and reproducibility are described for a series of current diesel engine oils. A comparison of the results with engine performance test data and with other test methods such as the thin film microoxidation test is made. The effect of variables such as temperature and pressure indicates significant variation due to the relative rates of oxidation and evaporation as a major factor in the rate of deposit formation. Some applications of the method in the development of high temperature liquid lubricants are described.
