EFFECT OF SOME TURKISH VEGETABLE OIL DIESEL FUEL BLENDS ON EXHAUST EMISSIONS

For different types of vegetable oils of Turkish origin (sunflower, co rn, soybean, and olive oil) were blended with grade No. 2-D diesel fue l at a ratio of 20/80 (v/v). The effect of the compression ratio on ex haust emissions is investigated in an American Society for Testing and Materials (ASTM)-cooperative fuel research (CFR) engine working with the mentioned fuel blends and a baseline diesel fuel. A decrease in so ot, CO, CO2, and HC emissions and an increase in NOx emissions have be en observed for fuel blends compared to diesel fuel.
