Abstract
Ferrography is being applied to laboratory and field engines to understand better the wear processes taking place. Methods used to make ferrography quantitative and sensitive to a wide range of debris concentrations are presented. An equation describing the time-varying debris concentration in the engine was applied to ferrography data in order to calculate the particle generation rate and the filtering efficiency of a paper filter. Results using this technique in the laboratory are discussed. A medium duty truck engine from new to its present mileage of over 80000 mile was monitored every 50 h using analytical ferrography. The results of this study are presented.
