SPECTROGRAPHIC EXAMINATION OF DIESEL ENGINE SUMP OILS

Concentrations of metallic elements in diesel engine sump oils, as measured by emission spectrographic chemical analysis, were correlated with internal wear of specific engine parts: iron-liners, piston rings, aluminum-piston seizure, chromium-chromium plated rings, liners, copper and lead-bearings, sodium-radiator leakage. It is very difficult to make reasonable predictions of the internal wear from such spectrographic results without a considerable background of information for normal engines of the same time and extensive data on oil changes or additions, filter changes, etc. This technique gives its best returns when regarded as complementary to the perceptions and judgment of an experienced engineer.
