Abstract
Human beings are heavily dependent on crude oil for their various need of survival on this planet but the way humans use crude oil make scientists to think deeply about renewable sources. One of the substitutes for the fossil fuel is a biodiesel. Several research are done on different biodiesels which concludes that biodiesel can be surely used as an alternative or it can be used to decrease the use of specially diesel fuel. In this paper, a single-cylinder, water cooled CRDI diesel engine was run with jojoba biodiesel by changing input parameters i.e., blend% (10, 15 ,20 ,25, and 30), Load (0, 3, 6, 9, and 12kg), compression ratio (16, 17, 18, 19, and 20) and injection pressure (190, 210, 230, 250, and 270 bar) to maximize the performance parameters i.e., brake thermal efficiency (BTE) and Exhaust gas temperature(EGT) and minimize emission i.e., CO and NOx are analysed with the help of Response Surface Methodology technique. It uses MINITAB20 to conclude the results and graphs. The result showed that there is significant decrease in all emission variables except marginal increase in NOx emission. The results reveal that overall good performance of the engine with BTE was maximum (24.5%) at blend 25%, CR 19, load 9 kg and IP 210. EGT was found to be minimum (0.11%vol) at blend30%, CR 18, load 6 kg and IP 230 bar. The optimum value of the output variable which is described by RSM is at blend 10.2020%, IP 190 bar, CR 20, Load 2.7879 kg and values are NOx 224.2844 ppm, , CO 0.1105 %vol and EGT 190.6031℃.
