Hydrogen behavior in dual fuel mode diesel engine with nano diesel

Investigation focus the major problem of the compression ignition engine such as high smoke and oxides of nitrogen emission which cause health effect to human beings and alternate energy for an I.C engine. The simple and effective method for controlling the smoke and NOx emission in diesel engine could be achieved only by means of fuel reformulation. NOx emission was further improved by means of combusting of nanofluid emulsion as an injected fuel. In this present study experimental investigation was done in Kirloskar single cylinder, four stroke, constant speed, water cooled, and compression ignition engine coupled with the eddy current dynamometer. The experimental set up consists of AVL DI-gas analyser and AVL smoke meter was used for the measurement of HC, CO, CO2, NOx and smoke emissions. The emission characteristics showed better improvement for the reformulated fuel such as diesel emulsion and diesel nano emulsion. Smoke emission of the diesel emulsion was reduced from 46.2% to 44% and the oxides of nitrogen emission also reduced from 520 ppm to 320 ppm at peak power output compared to the diesel fuel. An oxide of nitrogen emission was further reduced to 250 ppm by addition of nano particle in the diesel emulsion. Combusting of reformulated Fuel in the diesel engine was a simple and effective method for improving the smoke and oxides of nitrogen emission, further improvement was achieved by addition of nano particle in the emulsified fuel.
