  • Abstract

Present study is concerned about analyzing and establishing the relationship between EGT and NOx. The results for EGT and NOx were obtained by conducting performance and emission tests on a 4-Stroke CI DI engine using Waste Cooking Oil Methyl Ester (WCOME), Methyl Ester of Jatropha (JME), Methyl Ester of Pongamia (PME), Methyl Ester of Composite Oil (COME), Second Grade Coconut Oil Methyl Ester (SGCOME) and petrodiesel. For comparison and validation, extracted values of results of these parameters from other researchers have also been considered. Performance and emission results of COME have already been analyzed. Physico-chemical properties of COME, WCOME and SGCOME have been found to be within the limits prescribed by BIS and ASTM standards. Analysis of the results have emphatically shown that EGT has a linear relationship with NOx irrespective of Mix, Blend, Injection pressure (IP) and oils used as feed stocks. The nature of the graphs showing variations of NOx with EGT in the range of EGT considered, conformed to an ā€˜Sā€™ curve. It has been concluded that measurement of EGT is more than sufficient for estimating NOx in the ranges of power output of the engines considered.

Keywords: EGT, NOx, COME, WCOME, SGCOME, ā€˜Sā€™ curve
