Multi Response Optimization of NOxEmission of a Stationary Diesel Engine Fuelled with Crude Rice Bran Oil Methyl Ester

Abstract: Résumé -Optimisation à réponses multiples de l'émission de NO x d'un moteur Diesel stationnaire alimenté par de l'ester méthylique d'huile de riz brut -Dans la présente étude, il a été tenté de réduire les émissions de NO x de l'ester méthylique d'huile de riz brut sans accroissement considérable de la densité de fumée lorsqu'il est utilisé comme carburant dans un moteur stationnaire à allumage par compression. Trois facteurs, à savoir le calage d'injection de carburant, le pourcentage de recirculation des gaz… Show more

“…Earlier investigations from this laboratory have optimised various engine factors to minimise NO x levels with minimal effect on smoke density and thermal efficiency. 30,[41][42][43] This study explores the possibilities of reducing both smoke and NO x emissions without affecting performance by employing oxygenate emissions.…”

“…As the present objective involves in optimizing the parameters of the engine for three responses (NO x , smoke, and BTE), multi response signal to noise (MRSN) approach was adopted for optimizing the factors involved in this investigation. Standard procedure and formulae as prescribed in the literature was employed for this purpose 33,40 …”
