Potent effect of prosopis juliflora (biodiesel + isopropanol + diesel) fueled with diesel engine and egr alteration
Abstract
Prosopis juliflora biodiesel and isopropanol and diesel fuel to examine the performance, combustion, and emission characteristics along with EGR. Experiments were carried out in a diesel engine with a cooled EGR setup. The 80% of PJB and 20% of ISP were blended by ultra-sonicator, then four test fuels, 10%, 20%, 30%, and 40%, were prepared on a volume basis, magnetically stirred, blended with an equivalent ratio of diesel and subjected to ultra-sonication. EGR was done at three different rates of 10% EGR, 20% EGR, and 30% EGR at a standard injection timing of 230 TDC. Experimental results revealed that with 30% (PJB + ISP) added fuel blend and 30%EGR, significant reductions in NOx and smoke emissions simultaneously with a slight drop in engine performance. For achieving optimum NOx-smoke reductions, higher EGR levels were to be employed for PJB + ISP-diesel blends. Both HC and CO emissions seemed to increase with increasing EGR rates.
