Combustion and emission characteristics of a direct injection, compression-ignition engine when operated on honge oil, HOME and blends of HOME and diesel

Abstract

This paper reports the results of research conducted to study the fuel properties of Honge oil and blends of its ester and the subsequent testing of these oils in a four-stroke, single cylinder, water-cooled, direct injection, compression-ignition (CI) engine. Experiments were conducted with injection timings of 19, 23 and 27° BTDC at various loads and at a constant rated speed of 1500 rev min1. The performance and emission characteristics of Honge oil and Honge oil methyl ester (HOME) blended with diesel, to produce blends designated B20, B40 and B80, were studied. The heat release rates, maximum rate of pressure rise, ignition delay, and combustion duration for these fuel combinations were determined. © 2008 Taylor & Francis.
