AB - An investigation has been made to compare the emission characteristics of 20%  orange oil methyl ester and 80% diesel in volumetric basis with Neat diesel  in hemispherical combustion chamber and toroidal combustion chamber.  Non-edible orange oil is selected and utilized to prepare alternative fuel to  be utilized in Diesel engine. The traditional method of transestrification is  employed for preparation orange oil methyl ester. The chemical properties of  prepared methyl ester were determined using fouriertransform infrared  spectroscopy method. Further its fuel properties were found based on American  Society for Testing and Materials standards and compared with Neat diesel  fuel properties. A compression ignition engine with electrical dynamometer  test rig with gas analyzer has been used. It is observed that 1% of NOx and  4% of HC emission reduced in toroidal combustion chamber engine. However,  smoke emission is found to be lower in hemispherical combustion chamber  engine.
