Ruwa don tsarin SCR. Muna bin ka'idodin muhalli
Ana kiran SCR mai zaɓi saboda an ƙera shi don rage haɗarin oxides na nitrogen a cikin iskar gas daga injunan diesel. Hanyar tana da tasiri sosai, amma maganin urea ya zama ƙarin kayan cikawa.
Yadda tsarin yake
Urea ta cikin bututun ƙarfe yana shiga cikin iskar gas ɗin bayan shaye-shaye da yawa zuwa mai kara kuzari. Ruwan yana tada bazuwar nitrogen oxides zuwa ruwa da nitrogen - abubuwan halitta da ake samu a cikin namun daji.
Sabbin buƙatun Hukumar Muhalli a cikin Tarayyar Turai suna tilasta wa masu kera motoci sarrafa ƙa'idodin fitar da abin hawa da sanya SCRs akan motocin da injinan dizal.
Abubuwan na jiki da na sinadarai
Liquid don tsarin SCR Adblue, ya ƙunshi maganin ruwa da urea:
- Ruwa mai lalacewa - 67,5% bayani;
- Urea - 32,5% bayani.
Adblue yana cikin nasa filastik ko tankin ƙarfe, galibi kusa da tankin mai. Tankin yana sanye da hula mai shuɗi a wuyan filler, yana da rubutun Adblue daidai. Wuyoyin filler na urea da tankunan mai suna da diamita daban-daban don kawar da yiwuwar kuskure lokacin da ake yin man fetur.
Wurin daskarewa na urea shine -11 ° C, tankin urea yana sanye da nasa hita. Har ila yau, bayan an dakatar da injin, famfo a cikin yanayin baya yana sake tura reagent baya cikin tanki. Bayan daskarewa, urea da aka narke tana riƙe da kayan aikinta kuma ya dace don ƙarin amfani.
Ruwan ruwa da buƙatun aiki
Matsakaicin amfani da ruwan aiki na SCR kusan kashi 4% na yawan man dizal na motocin fasinja, kuma kusan kashi 6% na babbar mota.
Tsarin binciken abin hawa a kan jirgin yana sarrafa sigogi da yawa na maganin urea:
- matakin a cikin tsarin.
- Urea zafin jiki.
- Matsi na maganin urea.
- Maganin allurar ruwa.
Ƙungiyar kulawa ta gargadi direba ta hanyar haskaka fitilar rashin aiki a kan dashboard cewa ana cinye maganin da sauri kuma tankin ya zama fanko. Direba ya wajaba ya cika reagent yayin tafiya. Idan an yi watsi da faɗakarwar tsarin, ƙarfin injin yana raguwa daga 25% zuwa 40% har sai an cika reagent.
