Analysis of Emission Characteristics on CI Diesel Engine Using Safflower Methyl Ester

Unmatched supply of fossil fuels and its inflation of prices have promoted the interest and serious concern about the alternative sources for fossil fuels. In this work, investigations have been carried out to study the emission and combustion charecteristics of Safflower Methyl Ester (SME) as a fuel to diesel engine. For this experiments are conducted on a single cylinder, water cooled, and four stroke stationary engine of 5.2 KW. This engine is coupled with eddy current dynamometer as loading unit. The engine has run with safflower methyl ester using different pistons of combustion geometry by volume basis and readings are recorded. These tests are carried out over entire range of engine operations at varying conditions of load. The emissions obtained from these experiments are computed and compared for different pistons of geometry and presented in this paper.
