Prediction of thermal performance and exhaust emissions of a diesel engine fueled with Simmondsia Chinensis oil methyl ester using ANN

Abstract

The research utilizes the biodiesel derived from the non-edible Simmondsia Chinensis oil. The blends were identified as B10, B20, and B30. Experimental trials at three various CRs (16, 17, and 18) at an AFIT of 25˚ (CA bTDC) (Advanced fuel injection timing) with standard injection pressure. The test results demonstrated that the B30 biodiesel in diesel (SCOME30) exhibited maximum BTE among the SCOME variants for a higher compression ratio of 18 at an AFIT of 25˚ CA bTDC. For instance, at CR18, BTE of B30 was 3% higher than B10 blend. However, against diesel the BTE was lower at all compression ratio. NOx emission was highest for B30 blend at all compression ratio. In specific, at CR18, NOx emission for B30 operation was 15% higher than B10 operation. The advanced fuel injection duration lowered the CO and HC emissions and marginally increased the NOx emissions.
