Experimental investigation of combustion characteristics of hybrid nanofuel based on manganese oxide and graphene oxide nanoparticles in the diesel fuel

By adding nanomaterials to various diesel engine base fuels, one gets nanomaterials enriched fuels, or nanofuels in short. This addition may influence significantly the properties and behavior of the fuel due to unique properties of nanomaterials. The main purpose of this research is to study the physico-chemical properties of diesel fuel containing NPs of Manganese Oxide (MnOx) synthesized with a concentration of 100 ppm and Graphene Oxide (GO) with concentrations of 10 and 20 ppm and also by their hybrids. In this regard, the partial changes in the physical properties of density and viscosity in nanofuels by the concentrations of 0.2% and 0.6%, respectively have been observed.  The study also is based on the effect of nanometal oxide additives like Manganese Oxide and Graphene Oxide to diesel fuel. Metal oxide additive are doped with diesel fuel. The changes in diesel fuel properties (viscosity, flash point and fire point) due to introduction of nanometal oxide additive were observed. The diesel fuel with nanometal oxide additive presented a marginal increase in performance. Exhaust emissions for the diesel fuel with nanometal oxide additive showed significant decrease in levels of pollutants emission.
