Abstract

In this paper, the performance and the emission testings are carried out on a single cylinder diesel engine. The experiment involves the blending of diesel with methanol, ethanol and biodiesel by some definite proportion by volume, in order to obtain the maximum blending at which the engine performs its best and also the emission of harmful gases get reduced. Biodiesel is obtained by trans-esterification of castor oil. Here the blending is done with 5%, 10% and 15% of methanol, ethanol and with 20% and 40% of biodiesel with that of diesel. By blending, improved efficiency of the diesel engine and consequently reduced emission of harmful gases can be obtained than diesel. Also the blended fuel has many other advantages. This blended fuel can be used in an automobile at lower cost than that of diesel and also with improved efficiency and reduced emission of gases.
