| dc.description.abstract | An investigation was carried out on the performance evaluation of I.C. engine using biodiesel. The physical and chemical properties were determined at different blends of biodiesel with HSD and the performance of I.C. engine was analysed using preheated inlet air by the exhaust gas of diesel engine with optimised temperature. The calorific value of the fuel decreased as the blends increased, however kinematic viscosity, specific gravity, flash and fire point, cloud and pour point and carbon residue increased as compared to HSD. HSD had no FFA and acid value, however as the percentage of biodiesel blends increased FFA and acid value increased. The effect of preheating inlet air by exhaust gas on diesel engine performance and exhaust emission characteristics with different blends of biodiesel at different loads were studied. Results indicated that the break power of engine increased for B20 and B40 blends compared to HSD but incase of B60, brake power decreased. Brake specific fuel consumption for B20 and B40 decreased and for B60 increased compared to HSD. Brake thermal efficiency (BTE) increased for all the fuel samples tested. Volumetric efficiency was decreased as the load increased but for B20 it was closer to that of HSD at no load condition. Comparatively better overall engine performance was found at higher load conditions with preheated inlet air to engine. Emission characteristics of engine indicated that the carbon monoxide emission decreased with 50 per cent load initially and further it increased as the load increased. Almost all the blends of biodiesel with diesel showed lower emission of CO2 in comparison with HSD at all loads. NOx emission for all blends of biodiesel is comparatively lower than that of HSD at different load. The reduction in emissions at medium load may be due to significant reduction in ignition delay and better combustion because of higher inlet air temperature and using inlet air preheated system. The operating cost of engine for B20, B40 and B60 was 2.86, 2.88 and 2.27 per cent lower than that of diesel. As the blends of biodiesel mixer was increased HSD, operating cost of engine decreased. | en_US |
