Ulwazi olusisiseko lwesivamvo seoksijini kunye nokuchongwa kunye nokugcinwa, zonke ngaxeshanye zikuxelela!
Namhlanje siza kuthetha malunga ne-oxygen sensors.
Okokuqala, indima yenzwa ye-oxygen
I-sensor ye-oksijeni isetyenziselwa ukubeka iliso umxholo we-oksijini kwi-gesi yokukhupha i-injini emva kokutshiswa, kwaye iguqule umxholo we-oksijini ibe ngumqondiso we-voltage kwi-ECU, ehlalutya kwaye inqume ukuxinwa komxube ngokwesiginali, kwaye ilungise. ixesha lokutofa ngokwemeko, ukuze i-injini ifumane owona mxube ulungileyo.
I-PS: I-sensor yangaphambili ye-oksijini isetyenziselwa ukufumanisa ukuxinwa komxube, kwaye i-sensor ye-post-oksijini isetyenziselwa ukuthelekisa umbane wesignali kunye ne-pre-oxygen sensor ukubeka iliso kwimpembelelo yokuguqulwa kwe-converter catalytic converter. .
Okwesibini, indawo yokufaka
Abenzi boluvo lweoksijini ngokubanzi beza ngababini, kukho ezimbini okanye ezine, ezifakwe kumbhobho wokukhuphela weendlela ezintathu zokuguqula i-catalytic ngaphambi nasemva.
3. Isishunqulelo sesiNgesi
Isishunqulelo sesiNgesi: O2, O2S, HO2S
Okwesine, ulwahlulo lwesakhiwo
Kukho iindlela ezininzi zokwahlula i-oxygen sensors, i-PS: i-oxygen sensors yangoku ishushu, kwaye imigca yokuqala neyesibini i-non-heated oxygen sensors. Ukongezelela, inzwa ye-oksijeni iphinde ihlulwe ibe phezulu (ngaphambili) i-oxygen sensor kunye ne-downstream (ngasemva) i-oxygen sensor ngokwendawo (okanye umsebenzi). Izithuthi ezininzi ngoku zixhotyiswe ngee-5-wire kunye ne-6-wire broadband ye-oxygen sensors.
Apha, ikakhulu sithetha ngezinzwa ezintathu zeoksijini:
Uhlobo lwe-Titanium oxide:
Esi sivamvo sisebenzisa i-semiconductor ye-titanium dioxide, kwaye ixabiso layo lokumelana lixhomekeke kugxininiso lwe-oksijini kwindawo ejikeleze i-semiconductor ye-titanium dioxide.
Xa kukho ioksijini eninzi ngeenxa zonke, ukuxhathisa kwe-titanium dioxide TiO2 kwandisa. Ngokuchasene noko, xa ioksijini ejikelezileyo incinci, ukuxhathisa kwe-titanium dioxide i-TiO2 iyancipha, ngoko ukuxhathisa kwe-titanium dioxide sensor ye-oksijini kutshintsha ngokukhawuleza kufuphi nomlinganiselo we-air-fuel ratio, kwaye i-voltage ye-output nayo itshintsha ngokukhawuleza.
Qaphela: Xa ubushushu buphantsi kakhulu, ixabiso lokumelana ne-titanium dioxide liya kutshintsha libe yinto engapheliyo, ukuze i-voltage ye-sensor output iphantse i-zero.
Uhlobo lweZirconia:
Imigangatho yangaphakathi nangaphandle yeetyhubhu ze-zirconia zifakwe ngoluhlu lweplatinum. Ngaphantsi kweemeko ezithile (ukushisa okuphezulu kunye ne-platinum catalysis), umahluko onokuthi uveliswe ngumahluko wokuxinana kwe-oksijini kumacala omabini e-zirconia.
Isivamvo se-oxygen esibanzi:
Ikwabizwa ngokuba yi-air-fuel ratio sensor, i-broadband oxygen sensor, i-linear oxygen sensor, uluhlu olubanzi lwe-oxygen sensor, njl.
I-PS: Isekelwe kwi-zirconia yohlobo olushushu lwe-oxygen sensor extension.
