Experimental investigation to control HC, CO & NOx emissions from diesel engines using diesel oxidation catalyst

Abstract The diesel engines are mostly used engines because of high efficiency, durability and low operating cost. The diesel oxidation catalyst was designed by using UGNX software. The beads were first undergone the wash coat and then catalyst coating. For wash coat a mixture of Aluminium Oxide (Al2O3), Cerium Oxide (CeO2) and Barium Nitrate (Ba (NO3)2) is mixed with Ortho Phosphoric Acid (H3Po4) and coated on the beads. After wash coat the catalyst i.e. Mn (NO3)2 materials are coated on the wash coated beads. Then the coated diesel oxidation catalyst (DOC) is equipped on test bench and the concentration of pollutants are taken out as using diesel based up on the experimental results CO and HC were reduced.
