摘要：
The present work submits an investigation about nano-additives influence upon performance and emission characteristics of a blended-biodiesel fueled diesel engine equipped with urea-SCR system. The base fuel utilized in this study was B20 blended biodiesel which contained of 20% waste frying oil biodiesel and 80% diesel fuel. Manganese oxide and cobalt oxide nanoparticles were used as nano-fuel additives with the mass fractions of 25 and 50 ppm in this study. Based on the experimental results, the brake specific fuel consumption and the brake thermal efficiency of nanoparticles blended fuel were considerably enhanced while the NOx and CO emission were appreciably decreased compared to those of base fuel.
