PERFORMANCE EVALUATION AND EMISSION ANALYSIS OF 4- S, I.C. ENGINE USING ETHANOL BIO-DIESEL BLENDED WITH DIESEL FUEL

Abstract

Environment air pollution and global warming are alarming concern worldwide. Increasing air pollution, rapid growth of industrialization and the global trend of urbanization have totally disturbed the eco balance of resources on earth. The present study was done to visualize the potential of ethanol and biodiesel as an alternative fuel in C.I. engine. The salient features of the investigation include: (i) The study of basic fuel properties of ethanol, biodiesel and their blends with diesel for C.I. engine. (ii) To evaluate the potential of using biodiesel, ethanol and their blends with diesel for C.I, engine. (iii) Study of the engine performance and exhaust emission characteristics for various blends. Experiment set up was developed to carryout engine performance and emission characteristic studies on selected fuel blends at different load conditions. The present work has resulted in giving a good insight into the performance and emission characteristics of the C.I. engine using ethanol, biodiesel, diesel fuel blends. As fuel property point of view density and pour point of all the fuel blends are under the standard limits for diesel fuel. Heat of combustion of all blends is found to be lower than that of diesel fuel alone. D70B20E10 give lower CO and HC emission and slightly higher thermal efficiency than other blends
