Experimental Studies on Effect of Nano particle blended Biodiesel Combustion on Performance and Emission of CI Engine

Abstract

This article is concerned with the study of effect of addition of Carbon Nano Tube (CNT) on the physiochemical properties of Biodiesel and to investigate its effect on the performance and emission of a single cylinder direct injection CI engine. The fuel selected for the present study were Diesel, Biodiesel blends (B20), and CNT blended –biodiesel. The Biodiesel used is Honge Oil Methyl Ester (HOME). Biodiesel Blends were prepared by adding 80% Diesel and 20% Biodiesel by volume with the help of mechanical homogenizer. CNT blended Biodiesel contains 50 ppm of CNT in one liter of biodiesel blends. The experimental studies were carried out in a single cylinder 4 stroke direct injection CI engine connected to an eddy current dynamometer with computerized test rig facility to measure the performance and emission. The experimentations were carried at a constant speed of 1500 rpm and varying the load on the engine. The results shows that increase in the Brake thermal efficiency with the inclusion of CNT to Biodiesel. The brake thermal efficiency of CNT added Biodiesel fuels were 2.24% better as compared to that of Biodiesel without the addition of nano particle at full load calculation. Also the reformulated fuel (Inclusion of CNT’s in the Biodiesel blends) shows considerable reduction in the pollutant emission.
