Ulwazi olusisiseko lwe-oxygen sensor kunye nokuchonga kunye nokugcina, konke oku kukuxelela ngaxeshanye!
Namhlanje siza kuthetha ngee-sensors ze-oxygen.
Okokuqala, indima ye-oxygen sensor
I-sensor ye-oksijini isetyenziswa kakhulu ukujonga umxholo we-oksijini kwigesi yokukhupha umoya yenjini emva kokutsha, kwaye iguqula umxholo we-oksijini ube sisignali ye-voltage eya kwi-ECU, ehlalutya kwaye imisele uxinzelelo lomxube ngokwesignali, kwaye ilungise ixesha lokujova ngokwemeko, ukuze injini ifumane uxinzelelo olufanelekileyo lomxube.
PS: I-pre-oxygen sensor isetyenziswa kakhulu ukubona uxinano lomxube, kwaye i-post-oxygen sensor isetyenziswa kakhulu ukuthelekisa i-voltage yesignali kunye ne-pre-oxygen sensor ukujonga isiphumo sokuguqulwa kwe-three-way catalytic converter.
Okwesibini, indawo yokufakela
Izinzwa zeoksijini zihlala ziza ngambini, zimbini okanye zine, zifakwe kwi-exhaust pipe three-way catalytic converter ngaphambi nasemva.
3. Isifinyezo sesiNgesi
Isifinyezo sesiNgesi: O2, O2S, HO2S
Okwesine, ukuhlelwa kwesakhiwo
Zininzi iindlela zokwahlulahlula ii-sensors ze-oksijini, PS: ii-sensors ze-oksijini zangoku ziyafudunyezwa, kwaye imigca yokuqala neyesibini zii-sensors ze-oksijini ezingafudunyezwanga. Ukongeza, i-sensor ye-oksijini yahlulwe yaba yi-sensor ye-oksijini ephezulu (ngaphambili) kunye ne-sensor ye-oksijini esezantsi (ngasemva) ngokwendawo (okanye umsebenzi). Izithuthi ezininzi ngoku zixhotyiswe ngee-sensors ze-oksijini ezi-5-wire kunye ne-6-wire broadband.
Apha, sithetha kakhulu ngeenzwa ezintathu zeoksijini:
Uhlobo lwe-titanium oxide:
Le sensor isebenzisa i-titanium dioxide yezixhobo ze-semiconductor, kwaye ixabiso layo lokumelana lixhomekeke kubungakanani be-oksijini kwindawo ejikeleze i-titanium dioxide yezixhobo ze-semiconductor.
Xa kukho ioksijini engaphezulu ejikelezileyo, ukumelana kwe-titanium dioxide TiO2 kuyanda. Ngokwahlukileyo koko, xa ioksijini ejikelezileyo incinci, ukumelana kwe-titanium dioxide TiO2 kuyancipha, ngoko ukumelana kwe-titanium dioxide oxygen sensor kutshintsha ngokukhawuleza kufutshane nomlinganiselo womoya-fuel wethiyori, kwaye i-voltage yemveliso nayo itshintsha ngokukhawuleza.
Qaphela: Xa ubushushu buphantsi kakhulu, ixabiso lokumelana le-titanium dioxide liya kutshintsha libe yi-infinity, ukuze i-sensor output voltage ibe yi-zero.
Uhlobo lweZirconia:
Umphezulu wangaphakathi nowangaphandle weetyhubhu ze-zirconia ugqunywe ngomaleko weplatinum. Phantsi kweemeko ezithile (ubushushu obuphezulu kunye ne-platinum catalysis), umahluko onokubakho ubangelwa kukungafani koxinzelelo lwe-oxygen kumacala omabini e-zirconia.
Inzwa ye-oksijini ye-broadband:
Ikwabizwa ngokuba yi-air-fuel ratio sensor, i-broadband oxygen sensor, i-linear oxygen sensor, i-wide range oxygen sensor, njl.njl.
I-PS: Isekelwe kulwandiso lwe-oxygen sensor yohlobo lwe-zirconia olushushu.
I-Zhuo Meng Shanghai Auto Co., Ltd. izimisele ukuthengisa iinxalenye zeemoto ze-MG&MAUXS zamkelekile ukuzithenga.
