Osmdes\u00e1t\u00e1 l\u00e9ta 20. stolet\u00ed znamenala v\u00fdznamn\u00fd zlom ve v\u00fdvoji technologie DPF, kdy se v\u00fdzkumn\u00edci zam\u011b\u0159ili na sofistikovan\u011bj\u0161\u00ed filtra\u010dn\u00ed syst\u00e9my. Keramick\u00e9 filtry s katalyz\u00e1torem se uk\u00e1zaly jako slibn\u00e9 \u0159e\u0161en\u00ed, proto\u017ee dok\u00e1zaly nejen zachycovat pevn\u00e9 \u010d\u00e1stice, ale tak\u00e9 pom\u00e1hat p\u0159em\u011b\u0148ovat je na m\u00e9n\u011b \u0161kodliv\u00e9 l\u00e1tky oxidac\u00ed.

V roce 2000 se skupina PSA Peugeot Citro\u00ebn stala prvn\u00edm v\u00fdrobcem, kter\u00fd v o\u010dek\u00e1v\u00e1n\u00ed t\u011bchto budouc\u00edch p\u0159edpis\u016f zavedl filtry jako standardn\u00ed v\u00fdbavu osobn\u00edch automobil\u016f. Tento regula\u010dn\u00ed tlak podn\u00edtil inovace, kter\u00e9 vedly k vysoce \u00fa\u010dinn\u00fdm a odoln\u00fdm DPF, kter\u00e9 jsou standardem v dne\u0161n\u00edch dieselov\u00fdch vozidlech.<\/p>\n\n\n\n
Filtr pevn\u00fdch \u010d\u00e1stic funguje tak, \u017ee fyzicky zachycuje \u010d\u00e1stice saz\u00ed, kter\u00e9 j\u00edm proch\u00e1zej\u00ed v\u00fdfukov\u00e9 plyny z motoru. DPF je obvykle vyroben z keramick\u00e9ho materi\u00e1lu, jako je kordierit nebo karbid k\u0159em\u00edku, a m\u00e1 vo\u0161tinovou strukturu s mikroskopick\u00fdmi p\u00f3ry. Tato struktura nut\u00ed v\u00fdfukov\u00e9 plyny prot\u00e9kat por\u00e9zn\u00edmi st\u011bnami filtru, kter\u00e9 zachycuj\u00ed a ukl\u00e1daj\u00ed pevn\u00e9 \u010d\u00e1stice. Na rozd\u00edl od katalyz\u00e1toru, kter\u00fd je pr\u016ftokov\u00fdm za\u0159\u00edzen\u00edm, je DPF filtr s pr\u016ftokem p\u0159es st\u011bnu, co\u017e znamen\u00e1, \u017ee zadr\u017euje v\u011bt\u0161\u00ed \u010d\u00e1stice v\u00fdfukov\u00fdch plyn\u016f a z\u00e1rove\u0148 umo\u017e\u0148uje plyn\u016fm odch\u00e1zet. Tento filtra\u010dn\u00ed proces je neuv\u011b\u0159iteln\u011b \u00fa\u010dinn\u00fd a zachycuje v\u00fdznamnou \u010d\u00e1st \u0161kodliv\u00fdch saz\u00ed produkovan\u00fdch vzn\u011btov\u00fdm motorem.<\/p>\n\n\n\n
Postupem \u010dasu se zachycen\u00e9 saze hromad\u00ed uvnit\u0159 filtru, co\u017e, pokud se ne\u0159e\u0161\u00ed, vede k ucp\u00e1n\u00ed a zv\u00fd\u0161en\u00e9mu protitlaku ve v\u00fdfukov\u00e9m syst\u00e9mu. Tento protitlak m\u016f\u017ee negativn\u011b ovlivnit v\u00fdkon motoru a spot\u0159ebu paliva. Aby se tomu zabr\u00e1nilo, mus\u00ed DPF proj\u00edt procesem zvan\u00fdm regenerace, p\u0159i kter\u00e9m se nashrom\u00e1\u017ed\u011bn\u00e9 saze spaluj\u00ed za vysok\u00fdch teplot a p\u0159em\u011b\u0148uj\u00ed se na mal\u00e9 mno\u017estv\u00ed popela a ne\u0161kodn\u00e9ho oxidu uhli\u010dit\u00e9ho. Tento samo\u010distic\u00ed mechanismus je z\u00e1sadn\u00ed pro to, aby DPF nad\u00e1le efektivn\u011b fungoval, a je kl\u00ed\u010dov\u00fdm aspektem jeho konstrukce a provozu.<\/p>\n\n\n\n
Regenerace DPF je proces spalov\u00e1n\u00ed nahromad\u011bn\u00fdch saz\u00ed zachycen\u00fdch filtrem. Jedn\u00e1 se o z\u00e1sadn\u00ed samo\u010distic\u00ed mechanismus, kter\u00fd zabra\u0148uje ucp\u00e1v\u00e1n\u00ed DPF, co\u017e by jinak vedlo ke ztr\u00e1t\u011b v\u00fdkonu motoru, sn\u00ed\u017een\u00ed spot\u0159eby paliva a potenci\u00e1ln\u011b n\u00e1kladn\u00e9mu po\u0161kozen\u00ed motoru. B\u011bhem regenerace se teplota v\u00fdfukov\u00fdch plyn\u016f zv\u00fd\u0161\u00ed na dostate\u010dn\u011b vysokou \u00farove\u0148 (alespo\u0148 600 \u00b0C), aby se zachycen\u00e9 \u010d\u00e1stice saz\u00ed sp\u00e1lily a p\u0159em\u011bnily na mnohem men\u0161\u00ed objem popela. Tento proces je nezbytn\u00fd pro udr\u017een\u00ed \u00fa\u010dinnosti DPF a zaji\u0161t\u011bn\u00ed toho, aby mohl i nad\u00e1le \u00fa\u010dinn\u011b zachycovat \u0161kodliv\u00e9 \u010d\u00e1stice.<\/p>\n\n\n\n

V takov\u00e9m p\u0159\u00edpad\u011b se na palubn\u00ed desce obvykle rozsv\u00edt\u00ed kontrolka, kter\u00e1 \u0159idi\u010de upozorn\u00ed.

Ano, existuj\u00ed t\u0159i hlavn\u00ed typy regenerace DPF: pasivn\u00ed, aktivn\u00ed a nucen\u00e1. Pasivn\u00ed regenerace prob\u00edh\u00e1 p\u0159irozen\u011b, kdy\u017e je vozidlo jelo trvale vysok\u00fdmi rychlostmi, nap\u0159\u00edklad na d\u00e1lnici. B\u011bhem tohoto typu j\u00edzdy je teplota v\u00fdfukov\u00fdch plyn\u016f dostate\u010dn\u011b vysok\u00e1, aby se automaticky sp\u00e1lily zachycen\u00e9 saze bez jak\u00e9hokoli z\u00e1sahu \u0159\u00eddic\u00ed jednotky motoru (ECU).
