Stability and Characterization of Nanofibers on Liquid filtration media in Automotive Filters

In automotives, filter serves as one of the most significant part of any vehicle. The demand for filters in direct injection and alternative fuel systems in engines have been increased and to prevent the injection system from untimely failure, filters with increased filter efficiency and life is needed. Currently, the cellulose media made on the wetlaid process is used for this study and the experiments are carried out by depositing the nanofibers over this media using electrospinning process. The preliminary studies were carried out by varying the process parameters such as Voltage, Needle diameter, Electrode spacing distance and concentration using Taguchi's L9 orthogonal array experimentation. The influence of process parameters on nanofiber diameter is also investigated by using ANOVA analysis. The stability and characterization of nanofibers were carried out on oil/fuel filtration media. Finally, an empirical model based on the mean analysis was developed for the prediction of nanofiber diameter in filtration media with enhanced performance in both life and efficiency.
