INVESTIGATION ON PERFORMANCE AND EMISSIONS OF A BIODIESEL ENGINE THROUGH OPTIMIZATION TECHNIQUES

Abstract

The study is aimed at investigating the effects of engine parameters on the erformance and emission characteristics of a single cylinder 5.2 kW diesel ngine. The experiments were designed using a statistical tool known as esign of experiments based on taguchi. Five parameters, namely ,Power P), Static injection pressure (IP), Injection timing (IT), Fuel Fraction (B) nd compression ratio (CR) were varied at four levels and the responses rake power, fuel economy and emissions were investigated. The optimum n alues of the response could be predicted using Signal - Noise ratio(S/N atio) and optimum combination of control parameters were specified. esults of confirmation tests showed good agreement with predicted uantities. A compression ratio of 17.7, blend of 20% karanja biodiesel B20), an injection pressure of 230 bar, injection timing of 27° bTDC and at 0 % Load were found to be optimal values for the karanja biodiesel lended diesel fuel operation in the test engine .
