“…The addition of Al 2 O 3 and Fe 3 O 4 nanoparticles to biodiesel increased the rate of heat release, as shown in Fig. 10B [191]. From the author's finding, the maximum amount of heat release rate for 80ppm Fe 3 O 4 nanoblend is 114.82 kJ/m 3 c and for 120ppm there is a slight decrease, but when compared with the biodiesel blend, the HRR for all the nanoblends is increased.…”

“…This is due to the high surface areas of nanoparticles, which increase their chemical reactivity, which in turn reduces the ignition delay. Figure 9B [191] shows the impact of Al 2 O 3 and Fe 3 O 4 nanoparticles on in-cylinder pressure, in which both the nanoblends have increased cylinder pressure compared with the biodiesel blend. Figure 9C [180] shows the variation of cylinder gas pressure when the engine was fueled with 20% pongamia methyl ester with 50,100 ppm nanoparticles and shows that the iron oxide nanoparticles added blends have a higher peak pressure.…”

“…From the observations, it was shown that adding 0.4 and 0.8 water-based ferrofluid to diesel fuel not only reduces NO X emissions but also slightly increases CO emissions. Syed [191] changed the dosing amount, i.e., from 40 to 120 ppm nanoparticles in a MME20 fuel blend. The results show that 80 ppm of both nanoadditives gives the best emission characteristics.…”

In recent years, the application of nanoadditives in biofuels is gaining much attention due to their increase in thermophysical properties such as high surface area, thermal conductivity, and mass diffusivity. However, lack of stability, high additive cost, and difficult recovery from engine exhaust are the high-priority and demanding characteristics, which may be chosen by many researchers. In this regard, the most promising nanoadditives are magnetite nanoparticles, having a high-specific area, strong magnetic response, control over the particle size and, most importantly, easy and rapid separation from exhaust gas by applying external magnetic bars. Moreover, it can be easily diluted into biodiesel, and thus, it can collect the advantages of biodiesel in water emulsion. From the literature survey, it is found that there is a lacuna in the synthesis and performance of magnetite nanofuels for internal combustion engine applications. Thus, the present study aims to epitomize the research findings related to the synthesis, characterization, stability, and properties of biodiesel/diesel-based fuels blended with magnetite nanoparticles and the influence of the magnetite nanofuels on engine performance. The study shows that the addition of nanoparticles to biodiesel has positive effects in reducing harmful emissions such as carbon black, smoke opacity and NOX, with improved thermal efficiency and fuel consumption.

“…In addition, the cerium oxide promoted the HC oxidation, and the NO and HC emissions were reduced by 30% and 40%, respectively. Similarly, adding Cu, Fe, Pt and graphene nanoparticles to diesel-biodiesel fuel blends can improve combustion and reduce emissions to varying degrees [36][37][38][39][40][41][42][43][44][45][46].…”

How to improve the combustion efficiency and reduce harmful emissions has been a hot research topic in the engine field and related disciplines. Researchers have found that nano-additives to diesel-biodiesel fuel blends have achieved significant results. Many research results and both current and previous studies on nanoparticles have shown that nano-additives play an essential role in improving the performance of internal combustion engines and reducing the emission of harmful substances. This paper summarizes the recent research progress of nanoparticles as additives for diesel-biodiesel fuel blends. Firstly, the excellent properties of nanoparticles are described in detail, and the preparation methods are summarized and discussed. Secondly, the effects of several commonly used nanoparticles as diesel-biodiesel fuel blends on combustion performance and harmful substances emissions in terms of combustion thermal efficiency, brake specific fuel consumption, CO, UHC and NOx, are reviewed. Finally, the effects of nano-additives on internal combustion engines, the environment and human health are discussed. The work carried out in this paper can effectively contribute to the application of nanomaterials in the fuel field. Based on our work, the researchers can efficiently select suitable nano-additives that enable internal combustion engines to achieve efficient combustion and low-emission characteristics.
