AdBlue

AdBlue^® he otinga urea wairangi 32,5% mai i te urea hangarau me te wai whakahekeheke. Ko te ingoa o te otinga ka taea ano te AUS 32, he whakarapopototanga mo te Urea Aqueous Solution. He waipuke marama kore tae, he haunga haukini ngoikore. Ko te otinga kaore he momo paitini, kaore he awangawanga kino ki te tinana o te tangata. Kaore i te mura, kaore ano kia whakaritehia hei taonga morearea mo te kawe.

AdBlue^® he whakaiti NOx e hiahiatia ana mo te whakamahi i nga Kaituku Huringa Whiriwhiri (SCR) i nga waka diesel. Ko tenei otinga ka whakauruhia ki roto ki te kaiwhakakopu, i muri i te werohia ki roto i nga hau wera wera, ka hurihia te urea kei roto i te hauhā (CO₂) haukini (NH₃).

wai, mahana

urea → CO₂ + 2NH₃

Ka whakautu a Amonia ki nga waikawa hauota (KORE_X) ka puta i te wa o te wera o te hinu diesel. Ko te hua o te tauhohenga matū, ka tukuna mai te hauota koretake me te kohu wai mai i nga haurangi whakapau. Ko tenei mahinga e kiia ana he whakahekenga catalytic whiriwhiri (SCR).

KORE + KORE₂ + 2NH₃ → 2n₂ + 3H₂O

I te mea he -11°C te pāmahana whakatioatanga tuatahi, kei raro i tenei pāmahana ka pakari te taapiri AdBlue. I muri i te whakaheke hukapapa, ka taea te whakamahi me te kore here. Ko te kiato o AdBlue i te 20 C ko 1087 – 1093 kg/m3. Dosing o AdBlue, kei te rongoa i roto i te tank motuhake, ka mau i roto i te motokā tino aunoa i runga i nga whakaritenga o te wae mana. Mo te taumata Euro 4, ko te nui o te taapiri AdBlue e rite ana ki te 3-4% o te nui o te wahie i pau, mo te taumata tukunga Euro 5 kua 5-7%. Panui Kahurangi^® te whakaheke i te kohi hinu diesel i etahi keehi tae atu ki te 7%, na te mea ka whakahekehia te utu nui mo te hoko waka e tutuki ai nga whakaritenga o te EURO 4 me te EURO 5.
