Ako sa vyr\u00e1ba a\u00a0ako p\u00f4sob\u00ed vo va\u0161om aute?<\/p>\n

 <\/p>\n

\u010co je syst\u00e9m SCR a kde sa nach\u00e1dza vo va\u0161om aute? <\/u><\/em><\/strong><\/h3>\n

Prostredn\u00edctvom syst\u00e9mu SCR \u2013 selekt\u00edvna katalytick\u00e1 redukcia \u2013 sa oxidy dus\u00edka (NOx) konvertuj\u00fa na vodu a dus\u00edk (bez oxidov).<\/p>\n

Ako je uveden\u00e9 na grafe, roztok AdBlue\u00ae (32,5 % MO\u010cOVINY + 67,5 % demineralizovanej vody) sa vstrekuje do katalyz\u00e1tora SCR. V katalyz\u00e1tore nastane reakcia, ktor\u00e1 premen\u00ed NOx na H2<\/sub>O a N2<\/sub>.<\/p>\n

 <\/p>\n

\u00a0Ako funguje SCR? <\/u><\/em><\/h3>\n

 <\/p>\n

Aby sme to zjednodu\u0161ili \u2013 k ur\u010dit\u00e9mu po\u010dtu reakci\u00ed<\/strong> doch\u00e1dza pr\u00e1ve v katalyz\u00e1tore SCR. Do katalyz\u00e1tora sa vstrekne AdBlue a n\u00e1sledn\u00e1 reakcia s\u00a0prvkami v katalyz\u00e1tore a NOx vedie k zn\u00ed\u017eeniu NOx o 90 %<\/strong>. Po tejto reakcii n\u00e1jdete u\u017e iba nepatrn\u00e9 mno\u017estvo dus\u00edka, vody a oxidu uhli\u010dit\u00e9ho (N2<\/sub>, H2<\/sub>O a mal\u00e9 mno\u017estvo CO2<\/sub>).
\nAby AdBlue\u00ae vykazovalo optim\u00e1lnu \u00fa\u010dinnos\u0165, pri jeho vstupe do katalyz\u00e1tora SCR musia ma\u0165 v\u00fdfukov\u00e9 plyny ur\u010dit\u00fapo\u017eadovan\u00fa teplotu<\/strong>. V\u00fdfukov\u00fd syst\u00e9m mus\u00ed by\u0165 preto dostato\u010dne zohriaty<\/strong>. Tak\u017ee umiestnenie katalyz\u00e1tora vo v\u00fdfukovom potrub\u00ed nie je n\u00e1hodn\u00e9.<\/p>\n

Niektor\u00ed v\u00fdrobcovia, ako napr. PSA Peugeot Citro\u00ebn, sa rozhodli, \u017ee katalyz\u00e1tor SCR umiestnia pred katalyz\u00e1tor DOC. Jedn\u00fdm z hlavn\u00fdch d\u00f4vodov pre tento krok je ten, \u017ee toto umiestnenie je ide\u00e1lne z h\u013eadiska zn\u00ed\u017eenia \u010dasu zohrievania katalyz\u00e1tora SCR.<\/p>\n

SCR pritom nie je \u017eiadnou novinkou ako by ste si mohli myslie\u0165.<\/u><\/em><\/strong><\/h3>\n

Katalyz\u00e1tor SCR bol vyvinut\u00fd v roku 1957<\/strong> americkou spolo\u010dnos\u0165ou Engelhard Corporation (v s\u00fa\u010dasnosti BASF). Odvtedy sa technol\u00f3gia pou\u017e\u00edva v priemysle na zn\u00ed\u017eenie emisi\u00ed NOx v priemyseln\u00fdch z\u00e1vodoch, na lodiach, vo vlakoch a v mnoh\u00fdch in\u00fdch odvetviach<\/strong>. Inform\u00e1cie o odvetviach n\u00e1jdete na na\u0161ej webovej str\u00e1nke: www.Adblue4you.com<\/a><\/p>\n

Technol\u00f3gia SCR sa dlho pou\u017e\u00edvala v odvetv\u00ed doprave<\/strong>. T\u00e1to technol\u00f3gia<\/strong> pomohla v\u00fdrobcom vyvin\u00fa\u0165 k\u013e\u00fa\u010dov\u00e9 rie\u0161enie na zn\u00ed\u017eenie NOx. V predch\u00e1dzaj\u00facom \u010dl\u00e1nku sme sa zmienili o tom, \u017ee v\u010faka tejto technol\u00f3gi\u00ed n\u00e1kladn\u00e9 vozidlo vyroben\u00e9 v roku 2016 vyp\u00fa\u0161\u0165a menej NOx ako osobn\u00e9 auto vyroben\u00e9 v roku 2000….<\/p>\n
