AdBlue

AdBlue^® iri 32,5% aqueous urea mhinduro inogadzirwa kubva mukutengesa yakachena urea uye yakadzvanywa mvura. Zita remhinduro rinogona zvakare kuve AUS 32, chinova chidimbu cheUrea Aqueous Solution. Imvura isina ruvara isingaonekwe ine hwema hwe ammonia. Mhinduro yacho haina chepfu zvimiro, haina hukasha pane muviri wemunhu. Iyo haina-inopisa uye haina kusarudzwa sechinhu chine njodzi kutakura.

AdBlue^® iri NOx inoderedza inodiwa kuti ishandise Selective Reduction (SCR) zvinokonzeresa mumadhiziri mota. Mhinduro iyi inounzwa mukati mekugadzirisa, uko, mushure mejekiseni mukati memoto unopisa flue, iyo iri urea yakaora ikaita kabhoni dhayokisaidhi (CO₂ammonia (NH₃).

mvura, inodziya

urea → CO₂ + 2NH₃

Amoniya inozoita ne nitrogen oxides (HERE_X) izvo zvinoitika panguva yekutsva kwemafuta edhiziri. Nekuda kwekuita kwemakemikari, isina kukuvara senitrogen uye mweya wemvura unosunungurwa kubva kumagasi ekudzimisa. Maitiro aya anonzi akasarudzika ekudzora ekugadzirisa (SCR).

HAPANA + HERE₂ + 2NH₃ → 2n₂ + 3H₂O

Sezvo tembiricha yekutanga yecrystallization iri -11 ° C, pazasi tembiricha iyi AdBlue yekuwedzera inoomesa. Mushure mekudzokororwa kudzokororwa, inogona kushandiswa pasina zvirambidzo. Kuwanda kweAdBlue pa20 C ndeye 1087 - 1093 kg / m3. Dosing yeAdBlue, iyo inochengeterwa mune imwe tangi, inoitika mumotokari zvizere otomatiki zvinoenderana nezvinodiwa zveiyo control unit. Panyaya yeEuro 4 level, huwandu hweAdBlue hwakawedzerwa hunoenderana ne3-4% yehuwandu hwemafuta anodyiwa, paEuro 5 emission level yatove 5-7%. Ad Blue^® inoderedza kushandiswa kwedhiziri mune zvimwe zviitiko kusvika kusvika ku7%, nokudaro zvichizadzisa zvishoma mutengo wakakwira wekutenga mota dzinosangana nezvinodiwa zveEURO 4 uye EURO 5.
