Due to the design challenges and low performance of engines in green fuels, the researchers started to investigate fuel blends. The inlet parameters also will influence the performance and, emission characteristics of the engines. Considering the effect of injection pressure, the current study revealed the clarity of distinct feedstocks that may be used effectively with esterified petrol blends at different injection pressure. This study has considered the various non-edible vegetable oil-based fuels such as Pongamia methyl ester-Gasoline blend [PME-5G], Jatropha methyl ester- petrol blend [JME-5G], Neem methyl ester- petrol blend [NME-5G], Mahua methyl ester- petrol blend [MME-5G], Dairy scum methyl ester - petrol blend [DME-5G], and Used cooking oil methyl ester - petrol blend [UME-5G] for investigation. The entire test is carried out in the CI engine of irrigation water pumping systems under the distinct injection pressures of 210, 230, and 250 bar with respective loading conditions of 0%, 20%, 40%, 60%, 80%, and 100%. The output parameters such as Brake power, Thermal efficiency, Specific fuel consumption, heat release rate, cylinder pressure and emission stanadrds are elaborately discussed. The final results show the maximum performance at higher injection pressure which is reverse in the case of emissions that exhibited.
由于绿色燃料发动机的设计挑战和性能低下,研究人员开始研究燃料混合物。进气参数也会影响发动机的性能和排放特性。考虑到喷射压力的影响,当前研究揭示了不同原料的清晰情况,这些原料在不同喷射压力下可与酯化汽油混合物有效使用。本研究考虑了各种非食用植物油基燃料,如桐油甲酯 - 汽油混合物[PME - 5G]、麻风树甲酯 - 汽油混合物[JME - 5G]、印楝甲酯 - 汽油混合物[NME - 5G]、马胡亚甲酯 - 汽油混合物[MME - 5G]、乳渣甲酯 - 汽油混合物[DME - 5G]和废食用油甲酯 - 汽油混合物[UME - 5G]用于研究。整个测试在灌溉水泵系统的CI发动机中进行,喷射压力分别为210、230和250巴,相应的负载条件为0%、20%、40%、60%、80%和100%。对制动功率、热效率、比燃料消耗、热释放率、气缸压力和排放标准等输出参数进行了详细讨论。最终结果表明,在较高喷射压力下性能最佳,而排放情况则相反。
