Investigation of Effects of Addition of Zinc Oxide Nano Particles to Diesel Ethanol Blends on Di Diesel Engine Performance, Combustion and Emission Characteristics

B. Prabakaran

World at present is in a crisis of faster depletion of fossil fuel. Ethanol is a renewable fuel. The objective of this paper is to analyze the effects of addition of zinc oxide nano particles with ethanol-diesel blends in a diesel engine performance, combustion and emission characteristics of blends B1 (with 100 ppm ZnO nano particles in 20% ethanol and 80% diesel), B2 (with 200 ppm ZnO nano particles in 20% ethanol and 80% diesel), B3 (with 300 ppm ZnO nano particles in 20% ethanol and 80% diesel), B4 (with 400 ppm ZnO nano particles in 20% ethanol and 80% diesel) and B5 (with 500 ppm ZnO nano particles in 20% ethanol and 80% diesel) were analyzed and compared with that of E20 (20% ethanol and 80% diesel). There was an increase of heat release in all the blends in comparison with that of E20. There was an increase of peak pressure for the blends in comparison with that of E20. Brake Thermal Efficiency (BTE) of the blends was higher than that of E20. CO and HC emissions were also comparatively lower than E20. There was a slight increase of NOx emission for the blends at full load in comparison with that of E20. At lower loads there was an increase of smoke emissions for the blends and at higher loads on par with that of E20.
