BIODIESEL PRODUCTION FROM LINUM USITATISSIMUM AND EFFECT OF LINSEED OIL METHYL ESTERS AND ITS VARIOUS BLENDS WITH GASOLINE ON FUNCTIONAL FEATURES OF DIESEL ENGINE

Vegetable oils are combined with an alcohol (methanol) to produce chemical compounds known as esters, and when these esters are used as fuels are call biodiesel. In this study, biodiesel fuel has been extracted from Linum usitatissimum and produced via trans-esterification mechanism; consequently its important features were adapted with standard ASTM D-6751. Followed by trust on high quality of the produced fuel, function of engine of TYM tractors at 100% maximum load using 0%, 25%, 50% and 75% biodiesel and diesel compounds was tested and evaluated. The results indicated that functional features of engine (power, torque, specific fuel consumption) using various fuel compounds have worked out close to each other, known similar to the function of engine with diesel. On the whole, with regard to the results from functional parameters of engine, it seems that use of Biodiesel production from Linum usitatissimum combined with gasoline can be a suitable method to consume them in diesel engines without any substantial deformation in engine and fueling system.
