THE Bosch ubhengeze izolo uguquko kwiinjini zedizili - hlaziya inqaku (iingxelo ze-CEO yenkampani zifanelwe ukufundwa ngononophelo). I-revolution ebonakala ngathi isekelwe ngokupheleleyo kubuchwephesha obukhoyo kwaye, ngoko ke, sisisombululo esinokuthi sisetyenziswe kungekudala kwiinjini ze-Diesel.
Ukuqinisekisa ukusebenza kobu buchwepheshe, ngobusuku, i-Diesels ibuyela ekudlaleni kwaye iphinde ibe kwindawo yokuhlangabezana neyona nto ifunekayo ekujoliswe kuyo-ezinye zazo zifika kwangoko ngoSeptemba. WLTP, uvile?
Kodwa wenze njani uBosch - enye yeenkampani ezazikuyeyona nto iphambili kwi-emissions scandal-wenza lo mmangaliso? Yiloo nto esiya kuzama ukuyiqonda kwimigca embalwa elandelayo.
Indlela Itekhnoloji Entsha Esebenza Ngayo
I-Ista sele iphelile kodwa kubonakala ngathi iBosch iyifumene indlela yokuvuselela iinjini ze-Diesel. Olu hlobo lwe-injini lwalu (kwaye ...) phantsi komlilo ngenxa yokukhutshwa kwe-NOx ephezulu abayikhupha emoyeni-into engafaniyo ne-CO2 iyingozi kakhulu kwimpilo yabantu.Ingxaki enkulu ngeenjini ze-diesel ayizange ibe yi-CO2, kodwa ukukhutshwa kwe-NOx okwenziwe ngexesha lokutsha - iinqununu sele zilawulwa ngokufanelekileyo yi-particle filter. Kwaye yayiyingxaki kanye, yokukhutshwa kwe-NOx, uBosch wayilungisa ngempumelelo.
Isisombululo esicetyiswa nguBosch sisekelwe kwinkqubo yokulawula unyango lwegesi yokukhupha.
Usukelo olulula ukoyisa
Okwangoku, i-NOx emission limit yi-168 milligrams ngekhilomitha. Ngo-2020, lo mda uya kuba ngu-120 mg / km. Itekhnoloji yeBosch inciphisa ukukhutshwa kwezi ntwana ukuya kwi-13 mg/km.
Iindaba ezinkulu malunga nobu buchwepheshe butsha beBosch zilula. Ixhomekeke kulawulo olusebenzayo ngakumbi lwevalve ye-EGR (Exhaust Gas Recirculation). UMichael Krüger, intloko yecandelo lophuhliso lwetekhnoloji yeenjini zedizili, uthetha ne-Autocar malunga "nolawulo olusebenzayo lobushushu begesi ephumayo".
Ethetha nale mpapasho yesiNgesi, uKrüger ukhumbule ukubaluleka kobushushu ukuze i-EGR isebenze ngobuchule obukhulu: “ i-EGR isebenza ngokupheleleyo kuphela xa amaqondo obushushu erhasi ephumayo engaphezulu kwama-200°C” . Ubushushu obungafane bufikelelwe kwizithuthi zasezidolophini.
"Ngenkqubo yethu sizama ukunciphisa yonke ilahleko yeqondo lokushisa, kwaye ngoko sizisa i-EGR ngokusondeleyo kangangoko kunokwenzeka kwi-injini". Ngokusondeza i-EGR kwi-injini, igcina ubushushu naxa uqhuba esixekweni, ithatha ithuba lobushushu obuphuma enjinini. Inkqubo ye-Bosch ikwalawula ngobukrelekrele iigesi zokukhupha ukuze kudlule iigesi ezishushu kuphela kwi-EGR.
Oku kuya kwenza ukuba kube lula ukugcina iigesi zijikelezwe kwakhona kwigumbi lokutsha lishushu ngokwaneleyo, ukwenzela ukuba iinqununu ze-NOx zitshiswe, ngokukodwa ekuqhubeni ezidolophini, okufunwa kakhulu kungekuphela nje ngokusetyenziswa kokusetyenziswa, kodwa nangokwemiqathango yokugcina ubushushu be-injini. .
Ifika nini imarike?
Njengoko esi sisombululo sisekelwe kwi-teknoloji ye-Bosch Diesel esele isetyenziswe kwimveliso yezithuthi, ngaphandle kokufuna nayiphi na inxalenye ye-hardware eyongezelelweyo, inkampani ikholelwa ukuba le nkqubo kufuneka ibone ukukhanya kwemini kungekudala.
