21st century locomotive technology: quarterly technical status report 26

Description: Parasitic losses due to hybrid sodium battery thermal management do not significantly reduce the fuel saving benefits of the hybrid locomotive. Optimal thermal management trajectories were converted into realizable algorithms which were robust and gave excellent performance to limit thermal excusions and maintain fuel savings.

21st Century Locomotive Technology: Quarterly Technical Status Report 12 DOE/AL68284-TSR12

Description: A unit pump system was installed on the single cylinder engine. The performance entitlement of the high-pressure common rail system at notch 4 and notch 8 was determined, and data was also compared with a production design multi-cylinder engine. Vibration testing of a hybrid-bus-design battery revealed extensive insulation wear. The vendor initiated design activities to address vibration. A cell-level test program was initiated to study battery current flow at room temperature and develop limits. The robustness and sub-optimal simplified implementation of fuel optimization algorithms was studied.

21st Century Locomotive Technology: Quarterly Technical Status Report 6 DOE/AL68284-TSR06

Description: Experimental work to map the performance of the High Pressure Common Rail (HPCR) system on a locomotive is in progress. The experimental trends agree with KIVA modeling predictions. Injection optimization is in progress. Electrically-assisted turbocharger modeling was used to study passenger locomotive performance improvements. Energy storage cycling life testing began, and an improved battery state algorithm was determined. The hybrid locomotive energy storage was prepared for energy management system algorithm testing. Progress in reliable methods for computing optimal driving plans, and methods to reduce the complexity of the necessary optimization are reported.
