AbstractA primary obstacle that must be overcome in order for unmanned surface vehicles (USVs) to be able to provide valuable service to the fleet is the need for maintenance personnel onboard the vessel. Failure of a single key component that could easily be replaced or repaired on a manned vessel could cause an USV to have to abort its mission or, perhaps, require a manned vessel to put itself and its crew at risk to retrieve or repair the USV. It is therefore desirable to develop an enhanced automated control system for diesel engines that can perform diagnostics and self-maintenance. Barron Associates, Inc. (BAI) and its subcontractor, Southwest Research Institute (SwRI), propose to develop such an automated system by leveraging BAI's generic diagnostic algorithms and SwRI's marine diesel engine control systems expertise and research facilities. To provide a marine diesel engine system that meets the requirements of this SBIR program, development tasks may be partitioned into three categories: (1) design a diesel engine configuration and control system for high fuel efficiency and durability; (2) incorporate a diagnostic system that can detect and isolate faults and take appropriate action; and (3) extend all scheduled maintenance intervals to at least 1,000 hours.
