  3. Abstract:
  4. Experimental tests were carried out to investigate the effects of adding water-based ferrofluid to diesel fuel in a diesel engine. These effects included the combustion performance and exhaust emission characteristics of the diesel engine. To this end, emulsified diesel fuels of 0, 0.4, and 0.8 ferrofluid/diesel ratios by volume were used in a four-stroke diesel engine, operating at 2200rpm. The results indicate that adding ferrofluid to diesel fuel has a perceptible effect on engine performance, increasing the brake thermal efficiency relatively up to 12% and decreasing the brake-specific fuel consumption relatively up to 11% as compared to diesel fuel. Furthermore, from the analysis of gaseous species of engine exhaust, it was found that NO x emissions were lower than that of diesel fuel while the CO emissions increased. In addition, it was found that nanoparticles can be collected at the exhaust flow using a magnetic bar. Copyright
