“…Thus, the fundamental study of a diffusive flame consists of the spray injection characteristics, droplet evaporation characteristics, flame combustion characteristics, etc. Investigations have been done to study the benefits of adding nanoparticles to diesel and biodiesel blends on the CI engine characteristics (Basha et al, 2022;Gad et al, 2023). The experimental analysis of the droplet evaporation characteristics validates the phenomenon of micro-explosions during nanofuel combustion (Mehrizi et al, 2022).…”

The severe impacts of emissions from combustion necessitate the need for advanced mitigation techniques. This study focuses on experimentally investigating the change in particulate matter (PM) emissions during the flame combustion of diesel blended with varying quantities of titania (TiO2) nano-additives. The initial observations using a Scanning Mobility Particle Sizer showed a reduction in the total number concentration (TNC) of PM emissions for TiO2-nanofuel samples compared to diesel. However, detailed investigations revealed the enhancement in the TNC of ultra-fine particles (UFPs) with mobility diameters less than 100 nm. This indicates the possibility of the emission of nano-additives during flame combustion, which enhances the number concentration of UFPs. The evolution of TiO2 nanoparticles is validated by performing the elemental composition analysis using energy-dispersive X-ray spectroscopy after sampling the PM emissions. A detailed experimental study also revealed the significance of the size and stability of the dispersed nanoparticles in the overall emissions. Ball milling (BM) was used for the size reduction of dispersed nanoparticles to enhance the dispersibility of the nano-additives. BM, when combined with bathsonication (BS), resulted in the highest reduction in the TNC (37.70% for Ti100 BM-BS, 48.46% for Ti150 BM-BS, and 53.27% for Ti200 BM-BS), highlighting the importance of size of the dispersed nanoparticles. The detailed analysis of UFPs showed an increase in the TNC of particulates in sub-23 nm (22.92% for Ti100 BS and 39.16% for Ti100 BM) and super ultra-fine (96.46% for Ti100 BS, 100.83% for Ti100 BM, and 16.73% for Ti100 BM-BS) regions for nanofuel samples in contrast to neat diesel.

“…The results of the testing show that Nahar oil biodiesel and its mixtures with carbon nanotubes can replace diesel as fuel in diesel engines effectively. Recently, the research community has been concentrating on the dependability aspects of biofuels, as well as the strengthening of engine performance components and burning qualities, to reduce exhaust emissions from conventional diesel engines through the utilization of dieselbiodiesel fuel mixtures that are loaded with NPs (Basha et al, 2022;Nachippan et al, 2022;Pullagura et al, 2024). Recent research studies on the utilization of nano-sized metals, nonmetals, natural, and mixed elements in the fundamental fuel for diesel engines have been published in the academic literature (Jin and Wei, 2023;Yusof et al, 2020).…”

As a sustainable replacement for fossil fuels, biodiesel is a game-changer in the energy sector. There is no strategy to minimize biodiesel's significance as a sustainable, clean fuel source in light of the increasing climate change and environmental sustainability concerns. Nevertheless, conventional biodiesel production methods often run into problems like inadequate conversion efficiency and inappropriate fuel properties, which impede their broad adoption. The revolutionary potential of nanotechnology to circumvent these limitations and revolutionize biodiesel consumption and production is explored in this review paper. There are new possibilities for improving biodiesel output and engine efficiency, thanks to nanotechnology, which can alter matter at the atomic and molecular levels. Using nano-catalysts, nano-emulsification processes, and nano-encapsulation procedures, researchers have made significant advances in improving biodiesel qualities such as stability, combustion efficiency, and viscosity. Through a comprehensive analysis of current literature and research data, this article elucidates the crucial role of nanotechnology in advancing biodiesel technology. By shedding light on the most current advancements, challenges, and potential future outcomes in nano-based biodiesel manufacturing and consumption, this review hopes to add to the growing corpus of knowledge in the field and inspire additional innovation. In conclusion, there is great hope for a sustainable energy future, increased economic growth, and reduced environmental impacts through the application of nanotechnology.
