“…Dobór wkładu filtracyjnego do filtru sprowadza się do określenia powierzchni materiału filtracyjnego, wynikającej z określonego zapotrzebowania powietrza przez silnik Q Sil oraz dopuszczalnej prędkości filtracji wynoszącej dla papierów filtracyjnych u Fdop = 0,03-0,12 m/s [1,2,3,6,7,12], przy czym wartości wyższe przyjmuje się dla samochodów osobowych. W odniesieniu do włóknin filtracyjnych obliczone prędkości filtracji przyjmują wartości znacznie większe w zakresie u Fdop = 0,18-0,52 m/s [5].…”

“…The selection of filter elements in the air cleaner depends on the area of the filtering material resulting from the engine air demand Q Sil and the admissible filtration rate that amounts to (for filtration papers) u Fdop = 0.03-0.12 m/s [1,2,3,6,7,12] (the greater values are assumed for passenger vehicles.) In the case of filtration fibers, the calculated filtration rates are much higher, in the range from u Fdop = 0.18-0.52 m/s [5].…”

Properties of filtering materials used as porous barriers in filter elements of motor vehicle air cleaners have been analyzed. Criteria of fiber and paper selection for the filter elements have been presented. A relation showing the filter life and a coefficient of dust absorption km of filtering materials have been presented. A methodology of research of the fiber filter element characteristics has been developed. Results of investigations of the characteristics of efficiency, filtering accuracy and drag of the filtering fiber operating at different filtering rates have been presented. The coefficients of dust absorption km of the filtering fiber have been determined. Changes in the granulometric properties of dust in the airflow downstream of the filtering fiber and paper have been presented.
