Indima yenzwa ye-post-oxygen.
Umsebenzi we-sensor kukufumanisa ukuba kukho ioksijini engaphezulu kwigesi yokukhupha umoya yenjini emva kokutsha, oko kukuthi, umxholo weoksijini, kwaye uguqule umxholo weoksijini ube sisignali ye-voltage ukuze idluliselwe kwikhompyutha yenjini, ukuze injini ikwazi ukufikelela kulawulo oluvaliweyo olune-air factor engaphezulu njengenjongo; Qinisekisa ukuba i-catalytic converter eneendlela ezintathu inamandla okuguqula ukungcola okuthathu kwi-exhaust hydrocarbon (HC), i-carbon monoxide (CO) kunye ne-nitrogen oxide (NOX), kwaye iphucule ukuguqulwa nokucocwa kokungcola okuphumayo.
Imisebenzi ye-sensor yile:
1, i-sensor ephambili ye-oksijini ibandakanya i-heating zirconia element ye-hot rod, i-heating rod by (ECU) computer control, xa umoya ungena kancinci (ubushushu bokukhupha umoya buphantsi) ukuhamba kwamandla ukuya kwi-heating rod heating sensor, okuvumela ukufunyanwa ngokuchanekileyo koxinzelelo lwe-oksijini.
2. Isithuthi sixhotyiswe ngee-sensors ezimbini ze-oksijini, enye ingaphambi kwe-three-way catalytic converter kunye nenye emva kwayo. Indima yangaphambili kukubona umlinganiselo womoya-fuel wenjini kwiimeko ezahlukeneyo zokusebenza, kwaye ikhompyutha ilungisa ubungakanani bokufakwa kwe-fuel kwaye ibale ixesha lokutsha ngokwesignali. Into ephambili ngasemva kukubona umsebenzi we-three-way catalytic converter! Oko kukuthi, izinga lokuguqulwa kwe-catalyst. Ngokuthelekisa nedatha ye-front oxygen sensor, sisiseko esibalulekileyo sokufumanisa ukuba i-three-way catalytic converter isebenza ngokuqhelekileyo (elungileyo okanye embi).
Yintoni eyenziwa sisiva-oksijini esaphukileyo emotweni?
01 Ukusetyenziswa kwepetroli okwandisiweyo
Ukonakala kwe-sensor ye-oksijini engasemva kuya kubangela ukusetyenziswa kakhulu kwepetroli. Oku kungenxa yokuba ukufakwa kwekhabhoni kwi-sensor ye-oksijini kunokukhokelela ekuphumeni kwesignali engaqhelekanga, nto leyo echaphazela umlinganiselo wokuxuba wenjini, nto leyo eyenza ukuba ingalingani. Xa umlinganiselo womxube wenjini ungalingani, ukuze kugcinwe ukutsha okuqhelekileyo, injini iya kulawula ukufakwa kwamafutha amaninzi, nto leyo ebangela umxube omninzi, nto leyo enyusa ukusetyenziswa kwamafutha. Ukongeza, ngenxa yokungasebenzi kakuhle kwe-sensor ye-oksijini, ulwazi olungachanekanga oludluliselwayo lunokubangela ukuba umxholo we-oksijini yenjini ube phezulu kakhulu, nto leyo ekhokelela ekusetyenzisweni kwamafutha amaninzi. Ke ngoko, xa i-sensor ye-oksijini yonakele, kufuneka itshintshwe ngexesha elifanelekileyo ukuze kuthintelwe ukusetyenziswa kwamafutha amaninzi.
02 Ukukhupha ukungcola kuyanda
Ukonakala kwe-sensor ye-oksijini engasemva kuya kubangela ukukhutshwa komoya ophumayo kakhulu kwisithuthi. Oku kungenxa yokuba i-sensor ye-post-oxygen yinxalenye ebalulekileyo yokusebenza okuqhelekileyo kwe-catalytic converter eneendlela ezintathu. Xa i-sensor ye-post-oxygen isilela, i-catalytic converter eneendlela ezintathu ayikwazi ukusebenza kakuhle, ukuze ingakwazi ukuguqula ngokufanelekileyo izinto eziyingozi zibe zizinto ezingenabungozi. Ngale ndlela, isithuthi siya kukhupha ukungcola okungakumbi ngexesha lenkqubo yokuqhuba, okubangela ukukhutshwa komoya ophumayo kakhulu.
03 Yehlisa isantya kancinci
Ukonakala kwe-sensor ye-oksijini engasemva kuya kubangela ukuba isithuthi sihambe kancinci. Oku kungenxa yokuba i-sensor ye-afteroxygen inoxanduva lokujonga ubungakanani be-oksijini ekhutshwa yinjini kwaye idlulisele olu lwazi kwinkqubo yolawulo lwekhompyutha yesithuthi. Xa i-sensor ye-afteroxygen yonakele, ikhompyutha yesithuthi ayinakufumana ngokuchanekileyo olu lwazi lubalulekileyo, ukuze injini ingakwazi ukulawulwa ngokuchanekileyo nokulungiswa. Oku kunokukhokelela ekunciphiseni ukusebenza kakuhle kokutsha kwenjini, nto leyo echaphazela ukusebenza kokukhawulezisa kwesithuthi, okwenza ukuba sihambe kancinci.
04 Isibane sokungaphumeleli kwenjini siya kuvulwa
Emva kokuba isenzi seoksijini sonakele, isibane sokusilela kwenjini siya kukhanya. Oku kungenxa yokuba isenzi seoksijini sinoxanduva lokujonga umxholo weoksijini okhutshwa yinjini kwaye sithumele idatha kwinkqubo yolawulo lwe-elektroniki yesithuthi. Xa isenzi seoksijini sonakele, asinakubonelela ngokuchanekileyo ngale datha, nto leyo ebangela ukuba inkqubo yolawulo lwe-elektroniki ingakwazi ukugweba ngokuchanekileyo imeko yokusebenza kwenjini. Kwimeko enjalo, inkqubo yolawulo lwe-elektroniki iya kucinga ukuba kukho ukusilela kwenjini, ngoko ke isibane sokusilela kwenjini siya kwazisa umqhubi.
