Abstract
Various nanofluids (NFs) have been prepared using nanoparticles (NPs) for dual fuel engine application in this present work. In the initial segment of the work, the NF's are prepared using aluminum oxide nanoparticles (Al2O3). Further, nanoparticles were blended with diary scum oil methyl ester (DiSOME) in the mass fraction of 10-30 ppm in steps of 10, with the assistance of a mechanically operated conventional homogenizer and an ultrasonicator. In the next segment of the work, Al2O3 NP's effect on the characteristics of ignition and engine outgas levels of a single cylinder four strokes direct injection diesel engine functioning on dual fuel mode using DiSOME and producer gas (PG) has been investigated. Engine testing showed that experiments with Al2O3 based NF and PG operation resulted in 11.5% amplified brake thermal efficiency, 23.2% reduction in smoke, 18.2-21.4% reduction in hydrocarbon (HC) and carbon monoxide (CO) emissions, while more significant nitric oxide (NOx) levels by 32.6% were achieved than the same fuel combination excluded NP's at 80% load.
