Evaluation of engine characteristics of diesel engines fuelled with MWCNT nano additive doped hemp biodiesel blends

The current study is to test and analyze the performance of a compression ignition engine powered by a blend of hemp biodiesel and multi-walled carbon nanotube (MWCNT) nano additive, with a special emphasis on engine parameters. By incorporating the MWCNT nano additive into the hemp biodiesel blends, prospective improvements in engine efficiency, emission reduction, and overall engine performance is noted. The study of these engine characteristics provides vital information into the viability and application of using hemp biodiesel blends in diesel engines but also sheds light on the effectiveness and influence of the MWCNT nano additive on the engine’s performance. Through a comprehensive experimental approach, including engine testing and data analysis, the effects of the hemp biodiesel-MWCNT nano additive blends on the engine’s operation and functionality are studied. The findings from this study show that the incorporation of MWCNT in hemp biodiesel gives a significant enhancement in brake thermal efficiency and hydrocarbon, carbon monoxide, and smoke emission reduction but a marginal increase in nitrogen oxide emission is observed compared to neat diesel. The results showed that the MWCNT additives improved combustion efficiency and reduced emissions. This research contributes to the present understanding of nano-enhanced biodiesel fuels; this paper offers a paradigm shift in improving renewable energy sources for IC engines. Novelty is in the application of MWCNTs to enhance performance and stability of hemp biodiesel as a potential route toward cleaner and efficient formulations of biodiesel.
