TAGUCHI: FACTORS INFLUENCING NOX EMISSIONS FROM A DIESEL ENGINE FUELLED WITH CRUDE RICE BRAN OIL METHYL ESTER BLEND

The major goal of this research is to reduce smoke density and brake thermal efficiency without sacrificing NOX emissions from a stationary diesel engine running on a crude rice bran oil methyl ester blend. The research will also look into the elements that may be affecting the goal. NOX emission, smoke density, and BTE are taken into consideration as the objective’s promising elements, while fuel injection timing, percentage of exhaust gas recirculation, and fuel injection pressure are chosen as the response variables. The most effective combination of the factor levels in achieving the objective was found, and the same was confirmed experimentally. Tests were carried out in accordance with the L9 orthogonal array, the most influencing factor for each response variable, as well as the graphs also drawn for each response variable.
