Fuel Properties Improvement of Jatropha Oil using Exhaust Heat of Diesel Engine
Abstract The aim of the present work is to design a helical coil heat exchanger to extract waste heat from exhaust gas of a diesel engine to improve the fuel properties of high viscous crude Jatropha oil (CJO). A detailed designed procedure of helical coil heat exchanger was reported in this paper. The results showed that the fuel properties like density and viscosity reduced by 2.13 and 48.76 % respectively by gaining temperature from exhaust gas. Finally preheated Jatropha oil (PJO) fueled to the 5.5 kW diesel engine and it operated smoothly with a maximum brake thermal efficiency of 29.15 % as compared to 29.88 and 28.33 % for HSD and CJO, respectively. The brake specific energy consumption of CJO and PJO was found to be only 2.84 and 5.47 % higher than that of HSD, respectively. Efficiency of the heat exchanger was found to be varying between 19 and 26 % with engine load.
