Experimental Investigation of Aqueous Cerium Oxide Nanofluid Blend in Diesel Engine

Abstract:

Influence of aqueous cerium oxide nanofluid on the major physicochemical properties of diesel and the performance and exhaust emission characteristics of diesel engine were investigated. 50cc of aqueous cerium oxide nanofluid was dispersed into 1 litre of diesel fuel for preparing test fuel. The diesel with and without aqueous cerium oxide nanofluid was tested in a direct injection diesel engine at 0%, 25%, 50%, 75%, and 100% of full load condition. nanosized cerium oxide has more surface area, higher activity and can react with water at high temperature to generate hydrogen and improve fuel combustion. Also cerium oxide acts as oxygen buffer causing simultaneous oxidation of hydrocarbons as well as the reduction of oxides of nitrogen. The results on the combustion of diesel mixed with aqueous Cerium oxide nanofluid showed an increase in total heat of combustion and a decrease in concentration of HC, NO_x and smoke in the exhaust emission from the diesel engine.
