“…The figure also shows that the HC emission of various blends is higher at higher compression ratios, which may be due to the improper mixing of fuel and air. Lower emission of HC of biodiesel is reported by some researchers [16] but, at the same time, higher emission of HC of biodiesel is also reported, which is attributed to improper atomization of the fuel [17]. …”

SummaryThe dwindling fossil fuel resources and the environmental degradation have spurred research interest to find better renewable alternative energy sources. Biodiesel is one such viable promising alternative fuel, which can be extracted from various renewable vegetable oils. In the present study, biodiesel extracted from neem oil is characterized for engine performance and emission analysis is done at various compression ratios (CR) and fuel blends. The brake thermal efficiency (BTE) of the blend B20 is considerably higher than that of diesel at CR 18, 20, and 22. The specific fuel consumption (SFC) increases with diesel blends due to a higher calorific value of diesel in comparison with biodiesel. All the biodiesel blends had lower carbon monoxide (CO) emissions compared with diesel, which indicates better combustion due to the presence of inherent oxygen. At lower CRs, the in-cylinder temperature is lower, which in turn reduces the nitrogen oxide (NO X ) emission. The overall engine performance is optimum at CR of 18 with the NB20 fuel blend.

“…The reduction in BP at 3600 rpm is observed to be 5.6% and 9.7% for B50 and B100 respectively. This is mainly due to the reduction in the lower heating value of biodiesel as explained by Buyukkaya [3] and S. Jindal [4]. The BSFC of different tested fuels at 25% load.…”

“…Three levels, 0%, 10% and 15% were selected for EGR. Earlier research work on stationary Diesel engine with various injection pressures suggested that till 250 bar injection pressure the performance of the engine operation was smooth [33]. Hence maximum fuel injection pressure was fixed as 250 bar and 210 bar (standard pressure), 230 bar and 250 bar pressure were chosen as three levels for injection pressure.…”

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 d'échappement (EGR ; Exhaust Gas Recirculation) et la pression d'injection de carburant ont été choisis, et leur effet combiné a été examiné en matière de maîtrise des émissions de NO x d'un moteur Diesel stationnaire alimenté avec de l'ester méthylique d'huile de riz brut. Trois niveaux ont été choisis pour chaque facteur et les émissions de NO x , la densité de fumée ainsi que le rendement thermique au frein ont été retenus en tant que variables de réponse. Les expériences ont été conçues en employant la méthode des plans d'expériences et la table orthogonale L 9 de Taguchi a été utilisée pour conduire les essais moteurs selon différents niveaux des facteurs choisis. Le Rapport Signal-Bruit de Réponses Multiples (RSBRM) a été calculé pour les variables de réponse et le niveau de combinaison optimum des facteurs a été obtenu en utilisant simultanément la conception paramétrique de Taguchi. Une expérience de confirmation a été menée pour le niveau de combinaison optimum des facteurs, puis les résultats ont été comparés avec les conditions de fonctionnement normal et une amélioration significative des variables de réponse a été observée.
