Impact of nano additives in di diesel engine to investigate performance and emission characteristics by using biodiesel blended with diesel

Abstract

To determine the engine performance and emission parameters of diesel engine using diesel and bio diesel blends with nano additives. Blends of biodiesel of different proportions are prepared to which the zirconium oxide and titanium oxide nano additives are added. Here Wheat Germ Oil is taken as base oil with both the nano additives. The nano additives which are used here are of 30-50 nm and are added to biodiesel in different proportions. The following properties like density, viscosity, flash point, fire point, calorific value, pour and cloud point are been taken for this investigation. The experiments were conducted on a single cylinder direct injection (4) stroke diesel engine. The fuel is used in diesel engine the performance is noted along with the emission characteristics. The experiments have been conducted for Carbon Monoxide(CO), Hydro Carbons (HC), Carbon Dioxide (CO2), Oxygen (O2), NO, Specific Fuel Consumption (SFC), Brake Thermal Efficiency (BTE). The variations are seen in above characteristics. All these are compared with Pure Diesel.
