Experimental Investigation of Upgraded Diesel Fuel with Copper Oxide Nanoparticles on Performance and Emissions Characteristics of Diesel Engine

Abstract

Abstract:The enhancement of the physicochemical characteristics of fossil fuel has been the subject of extensive research to achieve better efficiency and reduced emissions. Diesel is one of the fossil fuels that are highly consumed in daily life. This paper focuses on the behavior of a refined diesel fuel when copper oxide nanoparticles are added. The resulting blend of nano-diesel has been analyzed using a four-stroke engine under two loads indicating light vehicles and heavy duty vehicles. The nano-diesel was prepared by the aid of an ultrasonicator and a mechanical homogenizer. A base diesel was taken as a reference to distinguish the effect of the nanoparticles additives. Three different samples with different concentrations are utilized in this study. As a result, the fuel consumption, exhaust temperature, brake power, power losses and engine efficiency have been evaluated and compared to the base diesel in order to demonstrate and access the enhanced performance of the nano-fuel blend. The three concentrations conducted were 100 ppm, 200 ppm and 300 ppm of copper oxide nanoparticles. The results represented that the pure refinery diesel has low exhaust temperatures, high brake power and high efficiency as compared to the commercial diesel supplied from a gas station. In addition, 300 ppm copper oxide nano-diesel showed improvement in engine performances as compared to the other concentrations and pure diesel. In this context, lowest fuel consumption for both passenger cars and heavy duty vehicles was achieved, brake power for passenger cars only was improved and input power showed improvement however, exhaust temperature was the highest as for this fuel.

Investigating the Combined Impact of Water–Diesel Emulsion and Al2O3 Nanoparticles on the Performance and the Emissions from a Diesel Engine via the Design of Experiment

“…As shown in Table 3, the heating values and densities of water-diesel emulsion fuel samples have been determined using the weighted average approach [29,[42][43][44]. Furthermore, in our work, it is assumed that the heating value and density of aluminum oxide nanoparticles blended with water-diesel emulsion fuel will not change due to the marginal effect; similar assumptions were made in earlier studies [23,45,46].…”

Nanoparticles Additives for Diesel/Biodiesel Fuel Blends as a Performance and Emissions Enhancer in the Applications of Direct Injection Diesel Engines: A comparative Review

“…The EDAX result demonstrates that the produced CuO nanoparticles are free of any additional elemental contaminants. By using GC-MS to examine the product, the Fatty Acid Methyl Esters were confirmed (FAMEs) [98]. The oil's viscosity was decreased through transesterification.…”
