摘要
The spray characteristics of a blended fuel containing conventional diesel and non-esterified biodiesel components were investigated. Experiments were performed to analyse the effects that blending ratio and injection pressure have on the spray behaviour. The process of spray injection was analysed with a laser diffraction particle analyser. In addition, spray atomization characteristics were studied using the Sauter mean diameter (SMD) varying the droplet concentrations under various injection conditions. Fuel containing non-esterified biodiesel components exhibited different spray patterns in comparison to that containing conventional diesel due to the high viscosity and large surface tension of the fuel. The results indicate that the SMD becomes smaller by increasing injection pressure, and larger by increasing the mixing ratio.
