Öğe Aspir ve kanola biyodizeli kullanımının egzoz emisyonu ve motor performansına etkilerinin incelenmesi(Küresel Mühendislik Çalışmaları Dergisi, 2016-04-01) Aydın, Hüseyin; Işık, Mehmet Zerrakki; Ziyadanoğulları Budak, Neşe; Oktay, Hasan; Bayındır, Hasan; Yücel, Halit LutfiBiodiesel fuel, which can be produced from crude or waste vegetable oil, is an important alternative renewable fuel for diesel engines. Particularly the use of vegetable oils for diesel engines has found an important place in several surveys. Biodiesel can be used alone, or blended with petrodiesel in any proportions. Biodiesel is suitable for usage at conventional diesel engines without modification. In this study, canola and safflower oil biodiesel methyl is realized by using the esterification method.. The produced biodiesels were blended in %(50) (in volume) with diesel fuel. The blends were tested in a four cycle, four cylinder Diesel engine. The effects of biodiesel addition to Diesel No. 2 on the performance and emissions of the engine were examined at full load. The resulting performance values were found to be similar to diesel fuel. In general, specific fuel consumption of biodiesel is higher than diesel at all engine loads. Significant difference between the exhaust temperature is not determined. AB50 biodiesel compared to diesel HC emissions at high loads began to decline. NOx, CO2 and O2 emissions ratio has increased at high loads for Biodiesel fuels. Experimental results showed that the produced biodiesels can be partially substituted for the diesel fuel at most operating conditions in terms of the performance parameters and emissions without any engine modification and preheating of the blends.
