Combustion behavior, performance and emission characteristics of diesel engine fuelled with biodiesel containing cerium oxide nanoparticles: A review

The demand for new materials in the field of electromagnetic interference shielding has increased dramatically in the last few decades due to the advancements in the electronics industry. To meet these growing demands, many new materials are being investigated to replace traditionally used metal sheets. Some of the promising materials being researched are polymer-based composites due to their low specific weight, ease of fabrication, and low cost. Some researchers have also looked into the modification and synthetization of new metal-based shielding materials. One of the significant disadvantages of modifying metallic materials is the reduction of their electrical conductivity that adversely affects the shielding effectiveness. Hence, the modifications carried out should be able to maintain the shielding effectiveness at high values while eliminating the shortcomings of metal sheets. In this review article, novel metal-based materials are analyzed for their shielding effectiveness. While some of the materials reviewed in this paper are merely metal-based composites, others consist of more complex additives including metal oxides and carbides. Apart from the shielding effectiveness, this article analyses the variation of other important properties such as electrical conductivity and mechanical properties for a few of these materials.

Water-in-diesel emulsions potentially favor the occurrence of micro-explosions when exposed to elevated temperatures, thereby improving the mixing of fuels with the ambient gas The distributions and sizes of both spray and dispersed water droplets have a significant effect on puffing and micro-explosion behavior Although the injection pressure is likely to alter the properties of emulsions, this effect on the spray flow puffing and micro-explosion has not been reported To investigate this, we injected a fuel spray using a microsyringe needle into a high-temperature environment to investigate the droplets’ behavior Injection pressures were varied at 10% v/v water content, the samples were imaged using a digital microscope, and the dispersed droplet size distributions were extracted using a purpose-built image processing algorithm A high-speed camera coupled with a long-distance microscope objective was then used to capture the emulsion spray droplets Our measurements indicated that the secondary atomization was significantly affected by the injection pressure which reduced the dispersed droplet size and hence caused a delay in puffing At high injection pressure (500, 1000, and 1500 bar), the water was evaporated during the spray and although there was not enough droplet residence time, puffing and micro-explosion were clearly observed This study suggests that high injection pressures have a detrimental effect on the secondary atomization of water-in-diesel emulsions
