“…Biodiesel derived from the vegetable oils is widely accepted by the researches as an alternative for diesel fuel since the important physiochemical properties are quite similar to --------------petrodiesel [3,5]. The combustion and performance behaviors of biodiesel-fueled Diesel engine also followed the similar trend compared to petrodiesel.…”

The present article discusses the effect of cerium oxide nanoadditive inclusion on the working characteristics (combustion, performance, and emission) of water emulsified soybean biodiesel-fueled single cylinder Diesel engine. Test fuels with 5% and 10% volume of water in soybean biodiesel along with mass fraction of 100 ppm cerium oxide nanoparticle were prepared using mechanical agitator and ultrasonicator, and the experiments were conducted under different loading conditions in a single cylinder Diesel engine. The experimental results reveal that the emulsion fuel increases the peak in-cylinder pressure and net heat release values compared to pure soybean biodiesel, and cerium oxide nanoparticle inclusion reduces the peak combustion parameters value. The performance parameters such as brake specific fuel consumption and brake energy consumption are significantly improved with emulsion fuel, and the nanoparticle inclusion further improve the performance parameters. At low load conditions, the emulsion fuels increase the hydrocarbon and CO emissions, whereas these emission magnitudes are reduced at high load conditions. As far as the NOx and smoke emissions are concerned, an increase in water concentration directly reduces the emissions irrespective of load conditions. The cerium oxide nanoparticle inclusion reduces the emissions level from the water emulsified soybean biodiesel-fueled diesel engine.

“…To support these experiments, research conducted by Halysun et al proved the same i.e. multiple injection strategies will reduce the NOx and PM emissions [13]. After a great deal of research, Sanghoon et al evaluated the adverse effects of injection pressure, injection timings, EGR rate, swirl ratio, and several injections approach in a diesel engine to achieve clean as well as efficient combustion.…”

The intention of this review study is to investigate the control measures of NOx emission. Even though the diesel engine sector plays a pivotal role in economic growth, it brings an unavoidable environmental deterioration. The current work reviews the effect of EGR, boost pressure variation, fuel modification, advanced engine combustion concepts, and after treatment processes for reducing NOx emission to EURO VI level. The outcomes of bio-diesel performance and other emission characteristics are too highlighted. In addition to this, specific attention is given to Porous Medium Combustion (PMC) technology adopted in diesel engines and a separate section is devoted. In order to facilitate a better understanding of PMC technology, simulation and experimental results of NOx emission are reported. Through this porous medium experimental study, it was found that NOx, HC and CO emissions were reduced significantly. Reducing the NOx and PM emissions might simultaneously increase the chance of usage of diesel and biodiesel blends fuelled CI engines in near future. The findings of this research work serve as best possible ways for achieving ultra-low NOx emission subjected to EURO VI norms level is suggested in future directions to give the reader insight and the track for the future investigation.

“…Even though, it is an effective emission reduction method, but not suited for long term use (increases engine wear and soot emissions) [25,26]. The EGR method can be utilized to a dual fuel diesel engine to reduce further emissions from diesel -biodiesel blends [27][28][29]. Importantly, increasing amount of low pressure EGR tends to reduce NO emission effectively than high pressure EGR, due to low temperature [30] and moreover, with the combination of other methods, the combined effect of EGR and advanced injection strategies are useful for emission reduction from diesel engines [31].…”
