Impact of Exhaust Gas Recirculation in VCR Engine Fuelled with Pongamia - Biodiesel

Abstract

Biodiesel is one of the alternatives which are being widely studied and production of biodiesel is limited by crop land displacement, the Trial examinations are carried on a four stroke Diesel Engine (DE) to inspect the solidness. Exhaust gas recirculation (EGR) is used for control the emission reduction such as NOx, HC & CO. The pongamia oil blended with B20, B40 and B50 of them biodiesel. The biodiesel oils performance are assessed. The performance parameters such as Specific Fuel Consumption (SFC) and Brake Thermal Efficiency (BTE) are calculated. The exhaust emissions such as unburned Hydro-Carbon (HC), oxides of nitrogen (NOx), carbon monoxide (CO), carbon dioxide (co2) and combustion and smoke parameters is discussed in this paper.
