Abstract (en)
[origin: WO02088278A1] A filter medium for liquid fuels and a filter device comprise at least one porous layer of a titanium-base component and at least one layer of a copper-base component having a higher normal electrode potential compared with that of titanium. To make the filterdevice able to activate the fuel fed for combustion, electron conduction is rendered to all components of the filter medium and accordingly to parts of the active zone of the filter device, while the layers are spaced apart but for a portion of the surface thereof to provide a galvanic coupling, the layer of the copper-base component being likewise porous and having a mean pore size and total porosity in excess of those of the layer of the titanium-base component. When fit in the filter case the layer of the copper-base component is upstream from the other layers. 2 indep. claims and 12 dependent claims; 1 drawing figure; 2 tables; 6 examples.
