Experimental Investigation of Emission Characteristics of CI Engine fuelled with Blends of Neem Biodiesel and Diesel

Abstract

With increasing biodiesel, CO emission decreases. Biodiesel itself has 11% oxygen, which help for complete combustion. Hence CO emissions decreases with increasing biodiesel percentage in fuel. Carbon di oxide emissions increases with increase in load . As load is increasing NOME gives lower carbon di oxide emissions. At all loads, NOME increased with diesel fuels and levels of oxygen for blends slightly increased as blend ratio increased, may be because fuels were oxygenated. Higher oxygen levels in fuel blends are always preferred. Variation of unburnt hydrocarbon with respect to load indicates that NOME is not shows decreasing trend at all loads.
