【 摘 要 】

This report details the ongoing fleet evaluation of an oil bypass filter technology by the Idaho National Engineering and Environmental Laboratory (INEEL) for the U.S. Department of Energy's FreedomCAR & Vehicle Technologies Program. Eight full-size, four-cycle diesel-engine buses used to transport INEEL employees on various routes have been equipped with oil bypass filter systems from the PuraDYN Corporation. Because of the reported filtering (down to 0.1 microns) capability of bypass filter systems, the technology is intended to extend oil-drain intervals. To validate the extended usability of the oil, an oil analysis regime is used to monitor the presence of necessary additives in the oil, to detect undesirable contaminants and engine wear metals, and to evaluate the fitness of the oil for continued service. The eight buses have accumulated 101,000 miles to date and some preliminary results are reported. The INEEL light-duty vehicle fleet is also being evaluated to identify candidate vehicles for inclusion in the test fleet.
