Study on performance characteristics of diesel engine using lemon balm oil based bio-diesel and a nano-additive

The combustion characteristics and thermal performance of the diesel fuel-burned internal combustion engine (DICE) were explored inside this paper, after employing bio-diesel (containing a blend of lemon balm oil, nano-titania and diesel) in steady state operation. Lemon balm oil had utilized as a bio-diesel and a fixed proportion (10 ppm) of nano-titania had deployed as the nano-additive. They were mixed with diesel fuel in varying lemon balm oil concentrations of 5 %, 15 %, and 25 %, respectively. The DICE utilized in this study was a single-cylinder, four-stroke water cooled diesel engine. The analysis revealed that when the percentage of bio-diesel is increased, brake thermal efficacy (BTE) drops. When a 5 % mix was used, the BTE of the DICE was nearly identical to that of plain diesel. Excluding the NOx emissions, the emissions parameters had significantly suppressed by incrementing the volume percentage of lemon balm oil. The greatest NOx emission had been discovered for a 25 percent concentration of lemon balm oil along with nano-titania in diesel.
