Filtr pevn\u00fdch \u010d\u00e1stic DPF (z anglick\u00e9ho Diesel Particulate Filter) p\u0159\u00edpadn\u011b FAP je od emisn\u00ed normy Euro 5 povinnou sou\u010d\u00e1st\u00ed naftov\u00fdch motor\u016f. \u010c\u00e1sticov\u00fd filtr opravdu dovede vylep\u0161ovat vzduch vypou\u0161t\u011bn\u00fd automobily. DPF dovede zachycovat pevn\u00e9 \u010d\u00e1stice \u2013 velice mal\u00e9 \u010d\u00e1ste\u010dky, kter\u00e9 jsou karcinogenn\u00ed. A nov\u011b jej najdete tak\u00e9 v benz\u00ednov\u00fdch motorech.<\/strong><\/p>\n

Kvalitn\u00ed DPF obsahuje komponenty z drah\u00fdch kov\u016f v\u010detn\u011b platiny a paladia, kter\u00e9 zaji\u0161\u0165uj\u00ed maxim\u00e1ln\u00ed efektivitu \u010di\u0161t\u011bn\u00ed spalin prost\u0159ednictv\u00edm katalyticky-reduk\u010dn\u00ed reakce.

Na\u0161t\u011bst\u00ed trvale kles\u00e1 jejich cena, tak\u017ee kvalitn\u00ed nov\u00fd \u010d\u00e1sticov\u00fd filtr lze pro b\u011b\u017en\u00e9 automobily koupit kolem ji\u017e od cca 15 tis\u00edc korun.<\/p>\n

Kone\u010dn\u011b tak snad kon\u010d\u00ed doba, kdy m\u00e9n\u011b inteligentn\u00ed motorist\u00e9, kter\u00fdm je jedno, \u017ee jejich auto vypou\u0161t\u00ed do vzduchu \u010dern\u00e9 oblaky rakovinotvorn\u00fdch saz\u00ed<\/strong>, u\u0161et\u0159\u00ed p\u00e1r tis\u00edc korun.

DPF je tedy \u00fa\u010dinn\u00fd pomocn\u00edk, kter\u00fd re\u00e1ln\u011b zlep\u0161uje vzduch ve m\u011bstech.
