This causes fast depletion of petroleum products, which leads to move towards the alternative fuels for researchers. Among so many alternative fuels for a diesel engine, non-edible vegetable oils are the most widely used under the test. The purpose of the present work is to investigate the engine performance and emission characteristics of DI (Direct Injection) diesel engine with different blends of safflower seed oil. Engine tests have been carried out to obtain comparison of fuel consumption, specific fuel consumption, brake thermal efficiency, volumetric efficiency, and smoke opacity and then compared with that of diesel fuel. The aim of the proposed work is to investigate experimentally the performance and emission characteristics of safflower biodiesel at different loads. A single cylinder, direct injection, compression ignition engine has been selected for the investigation. May - July 2017 Copyright © 2017 i-manager publications.
