Experimental Investigation of Biodiesel using Nano Additives in Diesel Engine

Objective: To determine the engine performance and emissions of a single cylinder Direct Injection (DI) diesel engine using diesel-biodiesel blends with nano additive. Method: Blends of diesel-biodiesel of different proportions are prepared, to which Nano additive Cerium Oxide (CeO2) is added. Properties like Flash point, Fire point, Calorific values are established for these blends. This fuel is used in single cylinder Direct Injection (DI) 4-strok diesel engine and performance of the engine is recorded along with emission details. Finding: In this present investigation cotton seed oil is taken as base oil (biodiesel) and Cerium Oxide (CeO2) as Nano additive. By using by using different blends of cotton seed oil methyl esters, for which Cerium Oxide (CeO2) Nano additives of size 30-50 nm is added in different proportions with neat diesel fuel. The experiments will conduct on a single cylinder Direct Injection (DI) 4-stroke diesel engine, and observed the variation of Specific Fuel Consumption (SFC), Brake Thermal Efficiency, Air-Fuel ratio, Exhaust Gas Temperature (EGT), NOx emissions, Carbon Monoxide (CO), and Hydro Carbons (HC) emissions. Experimental result are The results have shown lower fuel consumption, better performance, and lower emissions of Carbon Monoxide (CO), Hydro Carbons (HC) but higher emissions of (NOx), in comparison to neat diesel fuel.
