Oxygen sensor yooj yim kev paub thiab kev tshawb nrhiav thiab kev saib xyuas, txhua lub sijhawm qhia koj!
Niaj hnub no peb yuav tham txog oxygen sensors.
Ua ntej, lub luag haujlwm ntawm oxygen sensor
Cov pa oxygen sensor feem ntau yog siv los saib xyuas cov ntsiab lus ntawm cov pa oxygen hauv cov pa tawm ntawm lub cav tom qab kev sib tsoo, thiab hloov cov pa oxygen mus rau hauv lub teeb liab voltage rau ECU, uas soj ntsuam thiab txiav txim siab qhov sib xyaw ua ke raws li lub teeb liab, thiab kho. lub sijhawm txhaj tshuaj raws li qhov xwm txheej, kom lub cav tuaj yeem tau txais qhov zoo tshaj plaws concentration ntawm qhov sib tov.
PS: Lub pre-oxygen sensor yog tsuas yog siv los xyuas qhov concentration ntawm qhov sib tov, thiab tom qab oxygen sensor yog siv los sib piv cov teeb liab voltage nrog lub pre-oxygen sensor los saib xyuas qhov kev hloov pauv ntawm peb txoj kev catalytic converter. .
Qhov thib ob, txoj haujlwm installation
Oxygen sensors feem ntau tuaj ua khub, muaj ob lossis plaub, ntsia hauv cov yeeb nkab peb-txoj kev catalytic converter ua ntej thiab tom qab.
3. Lus Askiv luv
Cov ntawv luv luv: O2, O2S, HO2S
Plaub, kev faib cov qauv
Muaj ntau txoj hauv kev los faib cov pa oxygen sensors, PS: cov pa oxygen sensors tam sim no tau rhuab, thiab cov kab thawj thiab thib ob yog cov tsis muaj cua sov oxygen sensors.Tsis tas li ntawd, cov pa oxygen sensor kuj tau muab faib ua cov dej ntws (pem hauv ntej) oxygen sensor thiab downstream (rov qab) oxygen sensor raws li txoj haujlwm (lossis ua haujlwm).Ntau thiab ntau lub tsheb tam sim no tau nruab nrog 5-xaim thiab 6-xaim broadband oxygen sensors.
Ntawm no, peb feem ntau tham txog peb cov pa oxygen sensors:
Titanium oxide hom:
Lub sensor no siv cov khoom siv semiconductor titanium dioxide, thiab nws cov nqi kuj nyob ntawm cov pa oxygen hauv ib puag ncig ntawm cov khoom siv semiconductor titanium dioxide.
Thaum muaj oxygen ntau nyob ib puag ncig, qhov tsis kam ntawm titanium dioxide TiO2 nce.Ntawm qhov tsis sib xws, thaum cov pa oxygen nyob ib puag ncig me me, qhov kev tiv thaiv ntawm titanium dioxide TiO2 txo qis, yog li qhov kev tiv thaiv ntawm titanium dioxide oxygen sensor hloov pauv txav ze ze ntawm qhov theoretical huab cua-roj piv, thiab cov zis voltage kuj hloov pauv sai heev.
Lus Cim: Thaum qhov kub thiab txias qis heev, qhov kev tiv thaiv tus nqi ntawm titanium dioxide yuav hloov mus rau infinity, kom lub sensor tso zis voltage yuav luag xoom.
Zirconia hom:
Sab hauv thiab sab nrauv ntawm zirconia hlab yog coated nrog ib txheej ntawm platinum.Nyob rau hauv tej yam kev mob (siab kub thiab platinum catalysis), lub peev xwm sib txawv yog generated los ntawm qhov sib txawv concentration ntawm oxygen ntawm ob sab ntawm zirconia.
Broadband oxygen sensor:
Nws tseem hu ua huab cua-roj piv sensor, broadband oxygen sensor, linear oxygen sensor, dav ntau oxygen sensor, thiab lwm yam.
PS: Nws yog raws li cov cua kub zirconia hom oxygen sensor txuas ntxiv.
