Abstract

In this study, an experimental investigation was carried out to evaluate the impact of compression ratio, exhaust gas recirculation, and the start of injection on the performance and emission of single-cylinder VCR CRDI engine fueled with Melia dubia biodiesel and peppermint oil blends. Response surface methodology (RSM) was used to evaluate the effects of these multiple factors and their interactions with response variables like brake thermal efficiency (BTE), carbon monoxide (CO), oxides of nitrogen (NOx), hydrocarbon (HC), and smoke. Model analysis was done to validate the regression model developed for all responses by using Analysis of variance (ANOVA). Compression ratios 17.5, 19.5, and 21.5, exhaust gas recirculation of 10, 15, and 20%, and 19, 21, and 23 °CA were selected for the start of injection in this study. High desirability of 0.979 was obtained at the optimum operating parameters, viz. 19.5 of compression ratio, 23 °CAbTDC of the start of injection with 15% EGR where the values of BTE, CO, HC, NOx, and smoke were found to be 30.66%, 2.66 g/kWh, 0.076 g/kWh, 7.36 g/kWh, and 40 HSU respectively. Further, hydrogen and hydroxy (simulated) gas were inducted to improve the biofuel blend's performance, and their influence was investigated. A significant improvement in performance and reduction in emissions were observed with the usage of hydrogen gases. Researchers and organizations seeking to enhance engine performance and reduce harmful environmental emissions can benefit from this study.
