摘要：

This work presents the exergy analysis of a biogas-diesel dual fuel engine for various operating loads and flow rates using simulated biogas. The engine is operated with pure methane and raw biogas with variable CH4:CO2 ratios to assess the effects of carbon dioxide extraction, termed as methane enrichment. Addition of biogas reduces exergy destruction and improved exergy efficiency vis-a-vis diesel operation at moderate to high loads. Exergy destruction and efficiency were found to range from 45%-80% and 10%-40% respectively. Methane enrichment and increase in load improved exergy efficiency.
