Experimental Investigation on DICI Engine by Using Chemical and Nano Additives Blended Biodiesel

Abstract

An Experimental investigation is conducted to establish the feasibility of using Jatropha biodiesel in Direct Injection Compression Ignition (DICI) engines. While the biodiesel has certain limitations and adverse in terms of poor performance and high level of pollutants in the exhaust of the gases, specified chemical (Propylene Glycol, C3H8O2) and nano(Al2O3) additives are used with Jatropha biodiesel. The experiments are conducted in two phases by using an experimental test rig, which consists of a DICI engine, electric loading device, data acquisition system, and AVL exhaust gas analyzers. In the first phases of experimentation, the performance and emission characteristics of the engine are analyzed by using neat diesel and Jatropha biodiesel and in the second phase of investigation, similar experiments are conducted by using chemical and nanoadditives blended biodiesel. The results of biodiesel are compared with those of neat diesel and it is seen that the performance and emission characteristics of the engine are inferior in the case of biodiesel when compared with neat diesel. However, the results revealed that the working characteristics could be improved by selecting of proper chemical and nanoadditives in right proportions.
