Alternative diesel fuel study on four types of vegetable oils of Turkish origin

Four different types of vegetable oils of Turkish origin (sunflower, corn, soybean, and olive oil) were blended with grade 2-D diesel fuel at a ration of 20/80 (v/v). Blends were investigated in a diesel engine with a precombustion chamber at speeds between 1200 and 2100 rpm. Vegetable oils, diesel fuel, and fuel blends were characterized according to standard test methods. It was found that for short-term use, the fuel blends have engine characteristics similar to the baseline diesel fuel. Fuel blends also display less smoke emissions than diesel fuel.
