The aim of the present research work is to investigate the influence of Jatropha bio-diesel properties on various characteristics of a direct injection compression ignition engine. The experiments were performed at different engine operating regimes with the injection timing prescribed by the engine manufacturer for diesel fuel. The engine characteristics with Jatropha bio-diesel were compared against those obtained using diesel fuel. From the results, it is observed that the bio-diesel performance and emissions are lower than that of diesel fuel. However, the NOx emission Jatropha bio-diesel is more than that of diesel fuel. These high NOx emissions are due to the presence of unsaturated fatty acids and the advanced injection caused by the higher bulk modulus (or density) and high viscosity of Jatropha bio-diesel. Furthermore, the possibility for reduction of NOx emissions without expensive engine modifications (hardware) was investigated. Keeping this in mind, the Jatropha bio-diesel was preheated. The experimental results show that the retarded injection timing is necessary when using Jatropha bio-diesel in order to reduce NOx emission without worsening other engine characteristics. Results also indicate improved performance with the application of preheated bio-diesel. The only penalty for using preheated bio-diesel is the increase of smoke (soot).
