In this study, performance and exhaust emissions of biodiesel in a compression ignition engine was experimentally investigated. Therefore, biodiesel has been made by transesterification from cotton seed oil and then it was mixed with diesel fuel by 25% volumetrically, called here as B75 fuel. B75 fuel was tested, as alternative fuel, in a single cylinder, four strokes, and air-cooled diesel engine. The effect of B75 and diesel fuels on the engine power, engine torque and break specific fuel consumption were clarified by the performance tests. The influences of B75 fuel on CO, HC, NOx, Smoke opacity, CO 2, and O 2 emissions were investigated by emission tests. The engine torque and power, for B75 fuel, were lower than that of diesel fuel in range of 2–3%. However, for the B75, specific fuel consumption was higher than that of diesel fuel by approximately 3%. CO 2, CO, HC, smoke opacity and NO x emissions of B75 fuel were lower than that of diesel fuel. The experimental results showed that B75 fuel can be substituted for the diesel fuel without any modifications in diesel engines. ► The aim of this study was to investigate the effect of cottonseed oil based biodiesel blend with diesel fuel on the performance and exhaust gas emissions of a compression ignition engine. ► Therefore B75 fuel was selected to investigate the probability of using higher amount of biodiesel in diesel engines. ► Engine performance and emission test were performed. ► It has been concluded by the test results that the B75 fuel can be used directly in diesel engines especially as it considerably environmentally friend.
