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 ۲۰% blend of Congress grass Tamarind shell co-pyrolysis oil (CGTSCPO۲۰) 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 ۶۰۰ bar to ۱۱۰۰ bar with the same fuel IT of ۱۰ bTDC, the performance is enhanced. Studies reveal that, apart from nitrogen oxides (NOx), emissions decrease under ideal circumstances of ۸۰% load and ۱۰۰۰ bar pressure when brake thermal efficiency (BTE) increases. From the experimental results, it was observed that destruction of exergy for CGTSCPO۲۰ and diesel were ۵۹.۲۴% and ۵۰.۱۷%, respectively.
