Performance and Emission Characteristics of Di Diesel Engine Fuelled With Camphor Oil-Diesel Blends

In recent years, the usage of vehicles have been increased and this leads to the demand for fossil fuels. It has become an urgent need to carry out the research work on alternate source of energy to reduce the demand of fossil fuels and also to reduce the emission. Biofuel is one of the alternative sources of energy. The aim of the paper is to blend the camphor oil with diesel fuel at various proportions by volume. The camphor oil is directly blended with diesel fuel without any trans-esterification process, because of its low viscous property. The prepared blends were tested in a single cylinder DI Diesel engine at various load running at constant engine speed of 1500 RPM and coupled to eddy current dynamometer. Finally the observed performance and emission value of these blends were compared with pure diesel fuel operations. Among the results, the B15 blends gives better performance compared to B20 & diesel based on BTE. The B15 blends gives BTE (34%), B20 (BTE 32.95%) and diesel (BTE 31.5%) at full load conditions. The B20 blends emit 676 ppm of NOX, while diesel emits 617 ppm of NOX.
