Energy, exergy and environmental assessments of rubber seed oil methyl ester-diesel blend for an agricultural diesel engine under the influence of exhaust gas recirculation

The purpose of this study is to investigate the outcomes of fueling a diesel engine with biodiesel and recirculating the exhaust gases (EGR). The MRSO 30%'s destroyed energy and unaccounted losses fell by 6.72% and 2.33%, respectively, when compared to petroleum diesel. Diesel reduced the destroyed availability of MRSO 10%, 20%, and 30% by 66.67%, 66.93%, and 67.51%, respectively. In comparison to diesel, the exhaust gas availability and unexplained loss were decreased by 48.18% and 17.14%, respectively. The improvement in the trend towards diesel and MRSO 0%EGR was demonstrated by the availability of fuel with input energy of MRSO 10%, MRSO 20%, and MRSO 30%. Shaft availability and engine cooling water were improved for MRSO 30% with diesel under the same operating conditions by 32.41% and 5.84%, respectively. When compared to diesel for maximum load, the second law efficiency of MRSO 0%, MRSO 10%, MRSO 20%, and MRSO 30% was improved by 12%, 23.64%, 17.36%, and 6.32%, respectively. With high loads, the usage of EGR often results in an increase in BSCO, and BSHC emissions. It was discovered that the usage of 10% EGR was sufficient to reliably reduce BSCO, BSHC, and NO_x emissions at low and moderate loads.
