Correlation of the NOx emission and exhaust gas temperature for biodiesel
Metadata:Show full item record
Abstract This paper presents an algorithm which correlate Nitrogen oxides emitted and the combustion flame temperature during the combustion of biodiesel. An iterative process is used to determine the flame temperature taking into accounts the phenomenon of dissociation. The results of the algorithm are presented for different and air-to-fuel ratios. These predicted results are compared with laboratory tests conducted in the present study on a stationary diesel engine run on different blends of biodiesel. Within the range of tests carried out, the NOx emissions from biodiesel and its blends proved to be higher than those of petro-diesel fuel. Furthermore, in this study a strong correlation was found relating the NOx emissions and the flame temperature.
