Experimental Investigation on Effect of Nano Particles on Performance and Emission Characteristics of Diesel Engine Fuelled with Waste Cooking Oil Biodiesel

The depletion of conventional fuels and increase in global warming due to burning of conventional fuels forces scientists to develop sustainable alternative fuels which are renewable and suggested biodiesel as an immediate substitute for the conventional diesel fuel. The potential of waste cooking oil is increasing in the recent years as the people are avoiding usage of waste cooking oil (WCO). In this work, biodiesel was produced from WCO and used as partial substitute for the conventional diesel and studied the impact of titanium oxide (TiO 2 ) nanoparticle on engine’s emission level and performance. The engine tests were conducted on compression ignition engine and from the experimental results, it was observed that the addition of Al 2O3 enhances the engine’s thermal efficiency and minimises the emission levels.
