Investigation on diesel engine with biodiesel – gasoline fuel blends at a distinguished injection pressure

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.
