Investigation on compression ratio engine using nanoparticle blended diesel fuel

Abstract

In current scenario, vehicular emission contributes to major pollution source. Thus, it becomes necessary to reduce emission by improving the performance of the engines. Fuel borne catalyst proves to be a promising solution to reduce emission prior to combustion due to its ease of implementation without much modification of the existing engine design. The combined effect of Aluminum oxide (Al2O3) and cerium oxide (CeO2) nanoparticles, blended with diesel on the emission characteristics of a Variable Compression ratio (VCR) engine was carried out in the present study. The effect of various mass proportions of nanoparticles on the emission characteristics was determined. The net particle mass loading rate ranged between 0.5% to 1%. The nanoparticles were mixed in diesel with the aid of ultrasonication process. The results showed that for the nanoparticle blended diesel, a good deal of reduction was achieved in the emission characteristics with Unburnt Hydrocarbon (UBHC), carbon monoxide (CO), and NOx got reduced by 34%, 25%, and 5% compared to pure diesel.
