In coming days alternative sources of energy will be given more importance due to the gradual depletion of fossil fuels. Diesel engines are used for automobile application because they have low specific fuel consumption and high efficiency compared to S.I engines. Consumption of bio-fuels increasing in internal combustion engines due to the scarcity, increased cost, increased emissions of conventional fuels. Vegetable oils have been used to possible alternative to diesel fuel in CI engines. In the present work, initially the tests are conducted on the four stroke single cylinder water cooled direct injection diesel engine with constant speed by using diesel and base line data is generated by varying loads. After that experimental investigation has been carried out on the same engine and same operating parameters by using the linseed oil and blend of (sunflower and coconut oil) methyl esters in different proportions as L10, L20, L30 and SC10, SC20, SC30. Performance parameters like brake thermal efficiency, brake specific fuel consumption, volumetric efficiency and air fuel ratio are evaluated. The emissions like CO, CO2, NOX, HC and smoke density are measured. It is observed from the experimental results, that L20 and SC20 are the optimum blends after comparing performance parameters and emissions.
