The effect of mixed nano-additives on performance and emission characteristics of a diesel engine fuelled with diesel-ethanol blend

The use of ethanol in diesel engine is getting attention because of their significant impact on emission reduction. However, previous work reported that the introduction of ethanol in diesel fuel decreases the performance of the diesel engine. Therefore the study focuses on improving the performance as well as the emission characteristics of the diesel engine by adding mixed nanoadditives to the diesel-ethanol blend. The concentration of mixed nanoadditives (Al2O3 and TiO2) 50 ppm and 100 ppm were added to diesel-ethanol blend in the presence of a surfactant with the help of ultrasonic agitation. Significant improvements in performance parameters such as BTE and BFSC have been observed after addition of nanoadditives. The reduction in NOx, CO and UBHC emissions were also observed with the addition of nanoadditives whereas the emission of CO2 was increased. ? 2020 Elsevier Ltd. All rights reserved.
