THE Bosch umemezele izolo uguquko ezinjinini zikadizili - buyekeza lesi sihloko (izitatimende ze-CEO yenkampani zifanelwe ukufundwa ngokucophelela). Uguquko, okubonakala sengathi, lusekelwe ngokuphelele kubuchwepheshe obukhona, ngakho-ke, kuyisixazululo esingasetshenziswa maduze ezinjinini zikaDiesel.
Ukuqinisekisa ukusebenza kahle kwalobu buchwepheshe, ngobusuku obubodwa, odizili bayabuya basebenze futhi baphinde basesimweni sokuhlangabezana nemigomo efunwa kakhulu yokukhipha umoya - okunye kwakho okufika ngoSepthemba. WLTP, uzwile?
Kepha iBosch - enye yezinkampani ezaziyisizinda sokukhishwa kwegesi - yasenza kanjani lesi simangaliso? Yilokho esizozama ukukuqonda emigqeni embalwa elandelayo.
Indlela Ubuchwepheshe Obusha Obusebenza ngayo
IPhasika seliphelile kodwa kubukeka sengathi iBosch isiyitholile indlela yokuvuselela izinjini zikaDiesel. Lolu hlobo lwenjini belu (futhi...) luvutha ngenxa yokukhishwa kwe-NOx ephezulu abayikhipha emkhathini - into engafani ne-CO2 eyingozi kakhulu empilweni yomuntu.Inkinga enkulu ngezinjini ze-diesel ayizange ibe yi-CO2, kodwa ukukhishwa kwe-NOx okwakhiwa ngesikhathi sokusha - izinhlayiya sezivele zilawulwa ngokuphumelelayo ngesihlungi sezinhlayiyana. Futhi kwakuyiyo kanye le nkinga, yokukhishwa kwe-NOx, u-Bosch abhekana nayo ngempumelelo.
Isixazululo esinconywe yi-Bosch sisekelwe ohlelweni olusebenza kahle kakhulu lokuphatha igesi yokukhipha umoya.
Imigomo elula ukunqoba
Njengamanje, umkhawulo wokukhishwa kwe-NOx ungama-milligrams angu-168 ngekhilomitha. Ngo-2020, lo mkhawulo uzoba ngu-120 mg/km. Ubuchwepheshe be-Bosch bunciphisa ukukhishwa kwalezi zinhlayiya ku-13 mg/km nje.
Izindaba ezinkulu mayelana nalobu buchwepheshe obusha be-Bosch zilula uma kuqhathaniswa. Ithembele ekuphathweni okuphumelelayo kwe-valve ye-EGR (I-Exhaust Gas Recirculation). UMichael Krüger, inhloko yophiko lokuthuthukiswa kobuchwepheshe ezinjini zikadizili, ukhuluma ne-Autocar mayelana "nokuphathwa okusebenzayo kwezinga lokushisa legesi ephumayo".
Ekhuluma nale ncwadi yesiNgisi, uKrüger ukhumbule ukubaluleka kwezinga lokushisa ukuze i-EGR isebenze ngempumelelo enkulu: “ i-EGR isebenza ngokugcwele kuphela lapho izinga lokushisa legesi yokukhipha umoya lingaphezu kuka-200°C” . Izinga lokushisa elingavamile ukufinyelelwa esiminyaminya sasemadolobheni.
"Ngohlelo lwethu sizama ukunciphisa konke ukulahleka kwezinga lokushisa, ngakho-ke siletha i-EGR eduze ngangokunokwenzeka enjini". Ngokusondeza i-EGR enjinini, igcina izinga lokushisa ngisho nalapho ushayela edolobheni, isebenzisa ukushisa okuphuma enjinini. Uhlelo lwe-Bosch luphinde lulawule ngobuhlakani amagesi akhipha umoya ukuze kudlule amagesi ashisayo kuphela ku-EGR.
Lokhu kuzokwenza kube nokwenzeka ukugcina amagesi ajikeleziswa kabusha egumbini lomlilo eshisa ngokwanele, ukuze izinhlayiya ze-NOx zishiswe, ikakhulukazi ekushayeleni emadolobheni, okudinga kakhulu hhayi kuphela mayelana nokusetshenziswa, kodwa futhi mayelana nokugcina izinga lokushisa lenjini. .
Ingena nini emakethe?
Njengoba lesi sixazululo sisekelwe kubuchwepheshe be-Bosch Diesel obuvele busetshenziswe ekukhiqizeni izimoto, ngaphandle kokudinga ingxenye eyengeziwe ye-hardware, inkampani ikholelwa ukuthi lolu hlelo kufanele lubone ukukhanya kosuku maduze.
