Safflower seed oil was chemically treated by the alkaline transesterification reaction in methyl alcohol environment with potassium hydroxide (KOH) to produce biodiesel at JSPM’s charak college of Pharmacy laboratory. The produced biodiesel was blended with diesel fuel by 20% (B20) and 40% (B40) volumetrically. Some of important physical and chemical fuel properties of blend fuels, pure biodiesel and diesel fuel were determined. Performance and emission tests were carried out on a 4 stroke single cylinder diesel engine to compare biodiesel blends with petroleum diesel fuel. The engine used for the purpose of investigation is of variable compression ratio mechanism. Experiments were carried out for different load i.e. at 0kg, 3kg, 6kg and 9kg. The entire test was carried for compression ratio 17:1 and 18:1. Brake thermal efficiency was increased to 14% at 17:1 compression ratio for blend B40 running at full load as compared from pure diesel. Blend B40 shows minimum fuel consumption as compared from blend B20 and B40. On an average CO2 emissions reduced by 48%, NOX emissions reduced by 68% and HC emissions reduced by 60% at all load conditions. It can be concluded that the use of safflower oil biodiesel has beneficial effects both in terms of emission reductions and alternative petroleum diesel fuel.
