Investigation of Fuel Properties of Tea Seed Oil Biodiesel and Diesel Fuel Mixture

In this study, tea oil methyl ester was obtained from tea seed oil by transesteri-fication method. D100, B100, B50D50 and B20D80 test fuels were obtained by mixing the methyl ester fuel obtained from tea oil with diesel oil at a rate of 50% and 20% volumetrically.Fuel properties were determined by performing the density, kinematic viscosi-ty, cetane number, pH amount, clouding, pouring and freezing point tests, and calorific value, color determination, flash point, cold filter plugging point and copper rod corrosion tests of the test fuels. Considering the test results, it was concluded that the mixtures of B50D50 and B20D80 methyl ester produced from tea oil could be used in diesel en-gines without any modification on the engine and they were alternative fuels to diesel fuel. However, when it is used as B100 fuel, it is not suitable for use on diesel engines in terms of cold flow properties.
