Abstract
The main criteria of this experimental work is to study and analyze the performance and emission characteristics of a high speed single cylinder 4 stroke kirloskar AV1 Diesel engine with the carbon nanotubes, added with blends of ethanol and diesel. Ethanol could be blended with diesel easily, which is called as diesohol. The variation in performance parameters and emissions due to the addition of nanoparticles was studied by the experimentation. In this work, a 50ppm concentration of carbon nanotube (CNT) was added to the blends of ethanol and diesel to find out the variations when compared with diesel. Totally, three different types of blends were prepared, named as E1050CNT (ethanol 10%, diesel 90%,50ppm CNT), E2050CNT (ethanol 20%, diesel 80%,50ppm CNT) and E3050CNT (ethanol 30%, diesel 70%,50ppm CNT) to measure the performance parameters like Specific fuel consumption(SFC), Brake thermal efficiency(BTE) and characteristics of emissions like CO,HC,CO2 and NOX at a constant speed of 1500 rpm at various loads of 3kg, 6kg, 9kg and 12kg to make comparison with diesel. When the results compared with diesel, the SFC was increased, BTE is slightly reduced and the emissions like CO, HC and CO2 were decreased, but NOX was slightly increased with the nano-ethanol-diesel blends. The results from the experiment shows that the desired conditions of performance parameters like SFC and BTE were obtained with E10CNT50 blend, and a significant decrease in emissions was obtained with E30CNT50 blend. Finally, it is recommended to use the nano-ethanol-diesel blends for a diesel engine, as an acceptable and suitable alternative fuel without any modifications.
