Experimental Study on Performance and Emission Characteristics of Diesel Engine Using Karanja oil/Diesel as Fuel

Mechanical Engineering

The present paper investigates about the production of biodiesel from neat Karanja seed by chemical extraction process and mixing of the diesel in varying volume proportions in order to prepare a number of test fuels for engine application. The prepared test fuels are used in single cylinder water cooled diesel engine at various load conditions to evaluate the performance and emission parameters of the engine. The results of investigation show increase in brake power and brake thermal efficiency with load for all prepared test fuels. It is also seen from the results that HC emissions increase with increase in load for all prepared test fuels. CO emissions decrease with increase in load for all prepared test fuels. The smoke and NOx emissions also increase with increase in load for all prepared test fuels. During the course of this experimental investigation it was found that the overall performance and emission characteristics of the engine was satisfactory with all the test fuels and improved with repeated experiments. All the test results significantly improved with increase in load for all prepared test fuels. Therefore the present paper provides a strong platform to continue further investigation on using biodiesel fuel in a diesel engine.
