- W1512341307 abstract "In this study, a 15-L heavy-duty diesel engine and an emission control system consisting of diesel oxidation catalysts, NO x adsorber catalysts, and diesel particle filters were evaluated over the course of a 2000 hour aging study. The work is a follow-on to a previously documented development effort to establish system regeneration and sulfur management strategies. The study is one of five projects being conducted as part of the U.S. Department of Energy's Advanced Petroleum Based Fuels - Diesel Emission Control (APBF-DEC) activity. The primary objective of the study was to determine if the significant NO x and PM reduction efficiency (>90%) demonstrated in the development work could be maintained over time with a 15-ppm sulfur diesel fuel. The study showed that high NO x reduction efficiency can be restored after 2000 hours of operation and 23 desulfation cycles. Post-desulfation NO x emissions were 0.24 g/bhp hr (90% reduction) over the Federal Test Procedure and 0.17 g/bhp hr (93% reduction) in a steady-state test. However, pre-desulfation results indicate that average NO x emissions were higher over the course of the study (≈0.6 g/bhp hr). These results were achieved with a cycle average fuel economy penalty of 4.8%. PM results were confounded by repeated failures of the DPF hardware." @default.
