“…Figure 9 shows the variationof HRR against crank angle at various fuel injection pressures. Therefore, compared to pure diesel, the NPOME and NWCOME have lower peak pressure and maximum rate of pressure rise due toits slightly higher viscosity and inferior volatility [41]. It is observed that HRR of the heat release rate ofbiodiesel and nano additive fuel samples is reduced as a result of degradation in the formulation of the air-fuelmixture due to excessive viscosity [42].…”

In this experimental work focused on, the performance, emission, and combustion characteristics of Nano methyl esters of Punnai oil and Waste Cooking oil, and their diesel blends in a Compressed Ignition were experimentally tested. In the study, Nano Punnai oil methyl esters (NPOME), and Nano Waste Cooking Oil Methyl Esters (NWCOME) were prepared by the transesterification process. The Bio diesel-diesel blends were prepared by mixing 10%, 30%, 50%, and 70% of biodiesel with diesel. The effects of two nano methyl esters and their diesel blends on engine performance, combustion, and exhaust emissions are tested at different engine loads. Experimental results concluded that up to 30% of no methyl esters did not affect the performance, combustion, and emissions characteristics. On the other hand, above B30 (30% Biodiesel with 70% diesel) a reduction in performance, combustion, and emission characteristics is clear from the study.

“…Micro-explosions solely occurred in the presence of Al nanoparticles and intense micro-explosions can bring a tremendous growth in the evaporation of kerosene droplets via swiftly shattering the droplet into small-sized ones. However, Jiang et al [10] did not observe the occurrence of micro-explosions in the evaporation of Jatropha methyl ester-diesel blend at 873K and 973K, and they confirmed that low nanoparticle concentration was conducive to the evaporation of nano-fuel while high concentration did the opposite. In summary, due to the difference in experimental conditions and research methods, a substantial divergence on how nanoparticles affect droplet evaporation has not be resolved.…”

In order to study the influence of nanoparticles on the evaporation of nano-fuel and reveal the mechanism of heterogeneous heat and mass transfer induced by the dispersion of nanoparticles, CeO2 nano-fuels with different mass concentration and particle size were prepared based on the two-step method. The visualized evaporation apparatus for single suspended droplets was utilized to investigate the evaporation performance of diesel and nano-fuels at 673K and 973K using image processing technology. The results show that at 673K, evaporation of diesel and nano-fuel droplets accorded with classical D 2 -law and can be divided into a constant-volume evaporation stage and a quasi-steady evaporation stage. The addition of nanoparticles suppressed the evaporation of diesel droplets while increasing concentration or particle size can intensify the extent of suppression. At 973K, however, microexplosions of droplets occurred, and the variation of droplet diameter did not conform with classical D 2 -law. Evaporation was divided into a constant-volume evaporation stage and a fluctuating evaporation stage. Nanoparticles as heterogeneous nucleation sites enhanced the expansion intensity and micro-explosion intensity of droplets, in turn promoting the evaporation of fuel. With the increase of mass concentration or decrease of nanoparticle size, the promotion effect of nanoparticles on evaporation was more significant.

“…In addition, researchers have found several adverse effects in studies of diesel-biodiesel fuel blends [24], such as relatively low cloud and pour points, poor atomization of fuel injection, relatively low calorific value and generally high NOx emissions [25,26]. Thus, the researchers have tried newer approaches to improve engine performance and reduce exhaust emissions, such as the addition of fuel additives and pretreatment blends [27,28].…”

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.
