Abstract

Internal combustion engine energy and exergy analysis is essential when choosing a biofuel that can be used as an alternative to conventional diesel, as these analyses provide concerns about the quantity and quality of available energy. In this study, the multiple injection strategies (MIS) in an improved common rail direct injection (CRDI) diesel engine running on 20% blend of Congress grass Tamarind shell co-pyrolysis oil (CGTSCPO20) and diesel is optimized and energy and exergy analysis has been made at optimized condition. The optimal result reveals that there was a slight improvement in brake thermal efficiency (BTE) and reduction in emissions. By increasing the IOP from 600 bar to 1100 bar with the same fuel IT of 10 bTDC, the performance is enhanced. Studies reveal that, apart from nitrogen oxides (NOx), emissions decrease under ideal circumstances of 80% load and 1000 bar pressure when brake thermal efficiency (BTE) increases. From the experimental results, it was observed that destruction of exergy for CGTSCPO20 and diesel were 59.24% and 50.17%, respectively.
