AdBlue je bezbarv\u00e1 kapalina slo\u017een\u00e1 z demineralizovan\u00e9 vody a mo\u010doviny automobilov\u00e9 kvality (32,5 %), jak je stanoveno v norm\u011b ISO 22241. Je navr\u017eena tak, aby sni\u017eovala mno\u017estv\u00ed nej\u0161kodliv\u011bj\u0161\u00edch plyn\u016f emitovan\u00fdch dieselov\u00fdmi motory, \u010d\u00edm\u017e je \u010din\u00ed \u0161etrn\u011bj\u0161\u00edmi k planet\u011b a ohledupln\u011bj\u0161\u00edmi k n\u00ed. Konkr\u00e9tn\u011b je jej\u00ed funkc\u00ed neutralizovat emise oxid\u016f dus\u00edku (NOx) vznikaj\u00edc\u00edch spalov\u00e1n\u00edm nafty v motoru.<\/p>\n\n\n\n
Jak p\u0159esn\u011b funguje AdBlue? Od chv\u00edle, kdy do motoru vstoup\u00ed prvn\u00ed sm\u011bs vzduchu a nafty a dojde k jej\u00edmu spalov\u00e1n\u00ed ve v\u00e1lc\u00edch, syst\u00e9m SCR zachycuje nejv\u00edce zne\u010di\u0161\u0165uj\u00edc\u00ed plyny. Vst\u0159ikov\u00e1n\u00ed AdBlue do v\u00fdfukov\u00e9ho syst\u00e9mu motoru vyvol\u00e1v\u00e1 chemickou reakci prost\u0159ednictv\u00edm procesu zvan\u00e9ho hydrol\u00fdza, p\u0159i kter\u00e9m se oxidy dus\u00edku (NOx) p\u0159em\u011b\u0148uj\u00ed na voln\u00fd dus\u00edk (N2) a vodn\u00ed p\u00e1ru (H2O) \u2013 tedy zcela ne\u0161kodn\u00e9 plyny, kter\u00e9 jsou n\u00e1sledn\u011b vypou\u0161t\u011bny z v\u00fdfuku vozidla.<\/p>\n\n\n\n
Nyn\u00ed, kdy\u017e v\u00edme, jak AdBlue\u00ae funguje, je d\u016fle\u017eit\u00e9 v\u011bd\u011bt, pro\u010d je teplota kl\u00ed\u010dem k optim\u00e1ln\u00edmu provozu. N\u011bkter\u00e1 dieselov\u00e1 vozidla vybaven\u00e1 katalyz\u00e1torem SCR se pou\u017e\u00edvaj\u00ed pro pr\u00e1ci, kter\u00e1 vy\u017eaduje p\u0159eru\u0161ovanou rychlost. Traktory, dod\u00e1vky, autobusy nebo dokonce automobily, kter\u00e9 jezd\u00ed na kr\u00e1tk\u00e9 vzd\u00e1lenosti a s neust\u00e1l\u00fdmi zast\u00e1vkami, ne v\u017edy zaji\u0161\u0165uj\u00ed, aby chemick\u00e1 reakce mezi AdBlue\u00ae a plyny NOx byla \u00fa\u010dinn\u00e1. Je to pr\u00e1v\u011b kv\u016fli teplot\u011b, proto\u017ee nemohou udr\u017eet po\u017eadovan\u00fdch 260 \u00b0C.<\/p>\n\n\n\n
Co se stane, kdy\u017e dieselov\u00e9 vozidlo neudr\u017e\u00ed teplotu motoru? Pokud nen\u00ed dosa\u017eeno optim\u00e1ln\u00ed teploty, nemus\u00ed prob\u011bhnout spr\u00e1vn\u00e1 chemick\u00e1 reakce AdBlue a v d\u016fsledku toho m\u016f\u017ee mo\u010dovina, kterou obsahuje, krystalizovat.<\/p>\n\n\n\n
Kdy\u017e dieselov\u00fd motor vozidla nepracuje konstantn\u00ed rychlost\u00ed a teplota motoru se ne v\u017edy udr\u017euje na 260 \u00b0C, m\u016f\u017ee mo\u010dovina krystalizovat a tvo\u0159it mal\u00e9 usazeniny, kter\u00e9 se zachyt\u00ed v syst\u00e9mu. Z dlouhodob\u00e9ho hlediska mohou tyto pevn\u00e9 krystaly ucpat vst\u0159ikova\u010de a filtr pevn\u00fdch \u010d\u00e1stic v SCR syst\u00e9mu, co\u017e nakonec zp\u016fsob\u00ed probl\u00e9my s katalyz\u00e1torem.<\/p>\n\n\n\n
Co se stane, kdy\u017e je katalyz\u00e1tor ucpan\u00fd? AdBlue\u00ae nebude schopno reagovat se spalinami a k \u200b\u200bneutralizaci NOx nedojde. To znamen\u00e1, \u017ee v\u00fdkon motoru vozidla se m\u016f\u017ee sn\u00ed\u017eit a motor m\u016f\u017ee dokonce p\u0159estat fungovat, dokud nebude z\u00e1vada vy\u0159e\u0161ena.<\/p>\n\n\n\n
