Abstract :

The purpose of this paper is to study the performance and emission characteristics of an IDI CI Engine by using SVO (Jatropha) – Diesel blend in 40:60 proportions by volume under different preheating conditions and comparing the results with Diesel. As the viscosity of SVO is high,so blending with diesel makes the prepared fuel more viscous than diesel thus SVO Diesel blend is heated under different conditions (40 ° C, 60 °C, 80 °C & 100 °C ) which were developedusing counter flow heat exchanger using engine’s exhaust as the hot working fluid in order to decrease the viscosity of fuel. The results were taken on different loads using eddy current dynamometer as the loading unit. The performance of SVO Diesel blend like ake specific fuel consumption (bsfc),ake specific energy consumption(bsec) and thermal efficiency were calculated. The Emission characteristics were measured with the help of Smoke meter and 5–Gas Analyzer set up.Emissions were lowered except for that of NOx for the heated SVO Diesel blend in comparison to baseline diesel at room temperature.
