| Popis: | The present study is carried out to analyze the emission characteristics of a natural aspirated diesel engine running with water-in-diesel emulsion fuel at optimized engine operating condition. In the first phase of the experiment, key engine operating parameters say compression ratio and water concentration with diesel are optimized in order to obtain higher performance and lower emissions level at all loading conditions using Taguchi-grey relational analysis based on signal-to-noise ratio and grey relational grade. The optimized condition of engine operating parameters is identified as 10% WC (water concentration) with diesel and 18-CR (compression ratio) at all loading conditions. In the second phase, experiments are conducted at optimal condition and the emission characteristics are compared with neat diesel. The results reveal that 10% WC with diesel at 18-CR exhibits better NOx emission level at all loading conditions with a marginal penalty in other emissions. |
