Abstract

An experimental investigation is carried out to analyze the Combustion, performance and emission characteristics with single cylinder Compression Ignition (CI) engine, for Diesel and Jatropha biodiesel as a fuel with Alumina (Al2O3) and CMNT Nanoparticles. The characterization of Nanoparticles is done with XRD and TEM to determine its size. Nanoparticles in the amount of 25 ppm and 50 ppm are added with the help of mechanical agitator and magnetic stirrer. The physiochemical properties of the fuel blends like the flashpoint, Calorific value, and Cetane number are increased due to the addition of Nanoparticles. The addition of Nanoparticles showed reduction in ignition delay period, improved net heat release rate and better combustion characteristics. For the full load condition the performance of the engine, BTE is increased for JBD20+AL50CMNT50 blend by 7.37% and 0.67% in comparison of JBD20 and D100 blend, respectively. The most significant reduction in emission parameters like NOx is reduced by 651 ppm for JBD20 to 479 ppm and CO emission 0.11 % to 0.08% by volume for Alumina and CMNT 50ppm blend with JBD20. Results infer that JBD20+AL50CM NT50 have the highest Brake thermal efficiency , and the emission parameter like CO, HC and NOx lowest emission among all the prepared blends.
