摘要：In the present study experiments were carried out in a constant speed, stationary direct injection diesel engine and the performance was investigated. Initially the engine fueled with diesel, rice bran biodiesel (methyl ester), raw rice bran oil and preheated rice bran oil with standard injection timing and injection pressures at different load conditions and the performances were compared. With the help of a heat exchanger and using the exhaust gases, the rice bran oil was preheated. It was found that the pre heated rice bran oil exhibits a closer performance as compared to rice bran biodiesel. Then the injection timing and injection were varied and the performance and emission parameters were investigated using preheated rice bran oil. It was found that the brake thermal efficiency and oxides of nitrogen were found to be higher and BSFC and smoke were found to be lower at 21° CA bTDC of injection timing and 230 bar injection pressure. From the test results the optimum injection timing and injection timing for the engine fueled with preheated rice bran oil were evaluated.
