Abstract: This study consists of an evaluation of health assessment approaches for the CAT 7 diesel engine. The report presents the processing method and results from two potential approaches for monitoring ground vehicle engine health. This work is based on data acquired from seeded fault testing performed on the engine by the U.S. Army Tank and Automotive Research, Development and Engineering Center (TARDEC) from May–August 2010. Correlation analysis and principal component analysis were performed on the data and the results are presented. The results show detection of the presence of the majority of the faults. It is anticipated that through the application of various processing techniques such as these, a better assessment of engine health, in particular, the early detection of subsystems faults, is possible.
