Indima yenzwa ye-post-oxygen.
Umsebenzi we-sensor kukuqinisekisa ukuba kukho ioksijini engaphezulu kwigesi yokukhupha i-injini emva kokutsha, oko kukuthi, umxholo we-oksijini, kunye nokuguqula umxholo we-oksijini ube ngumqondiso wombane wokuhambisa kwi-injini yekhompyutheni, ukuze injini inokufezekisa ulawulo oluvaliweyo olunomoya ogqithisileyo njengenjongo; Qinisekisa ukuba i-converter ye-catalytic yeendlela ezintathu inokusebenza okuphezulu kokuguqulwa kwezinto ezintathu ezingcolileyo kwi-exhaust hydrocarbon (HC), i-carbon monoxide (CO) kunye ne-nitrogen oxide (NOX), kunye nokwandisa ukuguqulwa kunye nokucocwa kwezinto ezingcolileyo.
Imisebenzi yomenzi woluvo yile:
I-1, i-sensor engundoqo ye-oksijeni ibandakanya i-zirconia yokufudumala intonga eshushu, intonga yokufudumeza nge-(ECU) yokulawula ikhompyutha, xa ukungena komoya kuncinci (iqondo lokushisa liphantsi) ukuhamba kwangoku kwinzwa yokufudumeza intonga yokufudumeza, eyenza ukufumanisa ngokuchanekileyo ugxininiso lweoksijini.
2. Isithuthi sixhotyiswe ngee-oxygen sensors ezimbini, enye ngaphambi kokuguqula indlela emithathu ye-catalytic kwaye enye emva kwayo. Indima yangaphambili kukubona umlinganiselo we-air-fuel we-injini kwiimeko zokusebenza ezahlukeneyo, kwaye ikhompyutha ilungisa inani le-injection ye-fuel kwaye ibala ixesha lokutshisa ngokuhambelana nomqondiso. Into ephambili ngasemva kukubona umsebenzi wendlela ezintathu zokuguqula indlela! Oko kukuthi, izinga lokuguqulwa kwe-catalyst. Ngokuthelekisa neenkcukacha ze-oxygen sensor yangaphambili, sisiseko esibalulekileyo sokubona ukuba i-converter ye-catalytic yeendlela ezintathu isebenza ngokuqhelekileyo (elungileyo okanye embi).
Inzwa yeoksijini eyaphukileyo yenza ntoni emotweni?
01 Ukonyuka kokusetyenziswa kwamafutha
Ukonakaliswa kwenzwa ye-oxygen yangasemva kuya kubangela ukwanda kokusetyenziswa kwamafutha. Oku kungenxa yokuba ukufakwa kwekhabhoni kwi-sensor ye-oxygen kunokukhokelela ekuphumeni kwesignali engaqhelekanga, nto leyo echaphazela umlinganiselo wokuxuba injini, iyenze ingalingani. Xa umlinganiselo womxube we-injini ungalingani, ukuze kugcinwe ukutsha okuqhelekileyo, i-injini iya kulawula i-injection yamafutha amaninzi, okubangela umxube omkhulu, okwandisa ukusetyenziswa kwamafutha. Ukongezelela, ngenxa yokungaphumeleli kwe-sensor ye-oxygen, ulwazi olungachanekanga olugqithisiweyo lunokubangela ukuba umxholo we-oxygen we-injini ube phezulu kakhulu, okukhokelela ngakumbi ekusetyenzisweni kwamafutha. Ngoko ke, emva kokuba i-sensor ye-oxygen yonakalisiwe, kufuneka itshintshwe ngexesha ukuze ugweme ukunyuka kwamafutha.
02 Ukukhutshwa okungcolisekileyo kuyenyuka
Ukonakaliswa kwenzwa ye-oxygen yangasemva kuya kubangela ukukhutshwa okugqithisileyo kwesithuthi. Oku kungenxa yokuba i-sensor ye-post-oksijini yinxalenye ephambili yokusebenza okuqhelekileyo kwe-converter ye-catalytic yeendlela ezintathu. Xa i-post-oxygen sensor ihluleka, i-converter ye-catalytic yeendlela ezintathu ayikwazi ukusebenza ngokufanelekileyo, ukwenzela ukuba ingakwazi ukuguqula ngokufanelekileyo izinto ezinobungozi kwizinto ezingenabungozi. Ngale ndlela, isithuthi siya kukhupha izinto ezingcolisayo ngakumbi ngexesha lenkqubo yokuqhuba, okubangela ukukhutshwa okugqithisileyo.
03 Khawuleza kancinci
Ukulimala kwinzwa ye-oxygen yangasemva kuya kubangela ukuba isithuthi sinciphise. Oku kungenxa yokuba i-sensor ye-afteroxygen inoxanduva lokubeka iliso inani le-oksijini ekhutshwe yi-injini kwaye idlulisele le ngcaciso kwinkqubo yokulawula ikhompyutha yesithuthi. Xa i-afteroxygen sensor yonakalisiwe, ikhompyutha yesithuthi ayikwazi ukufumana ngokuchanekileyo le datha ebalulekileyo, ukwenzela ukuba injini ayikwazi ukulawulwa ngokuchanekileyo kwaye ilungiswe. Oku kunokukhokelela ekunciphiseni ukusebenza kakuhle kokutsha kwe-injini, nto leyo echaphazela ukukhawuleza kokusebenza kwesithuthi, okwenza kube lula.
04 Isibane sokusilela kwe-injini siya kulayita
Emva kokuba inzwa ye-oxygen yonakele, ukukhanya kokusilela kwe-injini kuya kukhanya. Oku kungenxa yokuba i-sensor ye-afteroxygen inoxanduva lokubeka esweni umxholo we-oksijini okhutshwe yi-injini kunye nokudlulisa idatha kwinkqubo yokulawula i-elektroniki yesithuthi. Xa i-sensor ye-afteroxygen yonakalisiwe, ayikwazi ukubonelela ngokuchanekileyo le datha, okubangela ukuba inkqubo yokulawula i-elektroniki ayikwazi ukugweba ngokuchanekileyo imeko yokusebenza ye-injini. Kulo mzekelo, inkqubo yolawulo elektroniki uya kucinga ukuba kukho ukusilela injini kunokwenzeka, ngoko ukusilela injini ukukhanya ukuba ulumkise umqhubi.
