The overall objective of this program is to develop the engine and lubricant system design approach that has the highest probability for commercial acceptance. Several specific objectives can also be identified. These objectives include: definition of the dominant wear mechanisms prevailing in coal-fueled diesel engines; definition of the specific effect of each coal-related lube oil contaminant; determination of the potential of traditional engine lubrication design approaches to either solve or mitigate the effects of the coal related lube oil contaminants; evaluation of several different engine design approaches aimed specifically at preventing lube oil contamination or preventing damage due to lube oil contamination; and presentation of the engine/lubricant system design determined to have the most potential. 2 figs., 3 tabs.
