I-AdBlue

I-AdBlue^® isisombululo se-urea esingu-32,5% esenziwe ngamanzi avela ku-urea ahlanzekile namanzi angenawo amandla. Igama lesixazululo futhi lingaba yi-AUS 32, okuyisifinyezo se-Urea Aqueous Solution. Nguketshezi olubala futhi olungenambala olunephunga elincane le-ammonia. Isixazululo asinazo izakhiwo ezinobuthi, asinawo umthelela onolaka emzimbeni womuntu. Alikwazi ukutsha futhi alihlukaniswa njengezinto ezinobungozi zokuhamba.

I-AdBlue^® kuncishiswa kwe-NOx ekusetshenzisweni kwe-Selective Reduction (SCR) catalysts ezimotweni zikadizili. Lesi sixazululo sethulwa ku-catalyst, lapho, ngemuva kokujova emagesi ashisayo, i-urea equkethwe ibola ibe yi-carbon dioxide (CO₂i-ammonia (NH₃).

amanzi, afudumele

urea → CO₂ + 2NH₃

I-ammonia bese iphendula ngama-nitrogen oxides (NO_X) ezenzeka ngesikhathi somlilo wephethiloli kadizili. Ngenxa yokusabela kwamakhemikhali, kukhishwa i-nitrogen engenabungozi kanye nomhwamuko wamanzi emagesi e-exhaust. Le nqubo ibizwa ngokuthi yi-selective catalytic reduction (i-SCR).

Cha + Cha₂ + 2NH₃ → 2n₂ + 3 amahora₂O

Njengoba izinga lokushisa lokuqala lokucwebezela liyi--11°C, ngaphansi kwaleli zinga lokushisa isithasiselo se-AdBlue siyaqina. Ngemuva kokunciphisa ngokuphindaphindiwe, ingasetshenziswa ngaphandle kwemingcele. Ukuminyana kwe-AdBlue ku-20 C kungu-1087 - 1093 kg/m3. Ukufakwa kwe-AdBlue, egcinwe ethangini elihlukile, kwenzeka emotweni ngokuzenzakalelayo ngokuhambisana nezidingo zeyunithi yokulawula. Endabeni yezinga le-Euro 4, inani le-AdBlue eyengeziwe lihambisana cishe no-3-4% yenani likaphethiloli elisetshenzisiwe, ezingeni lokukhishwa kwe-Euro 5 selivele lingama-5-7%. I-Ad Blue^® kunciphisa ukusetshenziswa kukadizili kokunye kuze kufike ku-7%, ngaleyo ndlela kususwe kancane izindleko eziphakeme zokuthenga izimoto ezihlangabezana nezidingo ze-EURO 4 ne-EURO 5.
