Koj puas tau xav tsis thoob li cas koj lub tsheb lub cav tswj qhov sib npaug zoo ntawm cov roj thiab huab cua kom pom kev ua haujlwm zoo thiab ib puag ncig tus phooj ywg? Nkag mus rau Oxygen Sensor, me me tab sis tseem ceeb tivthaiv uas ua lub luag haujlwm tseem ceeb hauv kev ua kom koj lub tsheb khiav tau zoo thiab ua haujlwm tau zoo.
Oxygen Sensor Ua li cas?
Lub Oxygen Sensor, feem ntau hu ua O2 sensor, ua haujlwm saib xyuas koj lub tsheb lub cav. Nws ntsuas qhov muaj nuj nqis ntawm cov pa oxygen hauv cov pa tawm thiab xa cov ntaub ntawv tseem ceeb no mus rau lub tsheb ntawm lub khoos phis tawj. Nyob rau hauv ob qho tib si sab sauv thiab hauv qab ntawm cov catalytic converter, cov sensors ua haujlwm tshwj xeeb.
Lub upstream Oxygen Sensor feem ntau tswj cov roj txhaj rau hauv huab cua / roj sib tov. Nws ua tiav qhov no los ntawm kev muab kev tawm tswv yim txuas ntxiv mus rau lub tsheb lub computer hais txog huab cua-rau-roj piv. Thaum qhov piv txwv no leans ntawm huab cua ntau dhau (qhov sib xyaw "lean"), lub sensor qhia qhov no nrog qhov tsis tshua muaj hluav taws xob (kwv yees 0.1 volts). Hloov pauv, yog tias muaj roj ntau dhau hauv qhov sib tov (ib qho "nplua nuj" sib tov), lub sensor kaw qhov hluav taws xob ntau dua (txog 0.9 volts). Thaum qhov zoo tshaj plaws huab cua-rau-roj piv tau ua tiav, tseem hu ua stoichiometric piv (14.7 feem ntawm huab cua rau 1 feem ntawm roj), Oxygen Sensor sau npe kwv yees li 0.45 volts.
Lub downstream Oxygen Sensor, ntawm qhov tod tes, saib xyuas cov catalytic converter kev ua tau zoo. Yog tias nws pom qhov tsis txaus ntseeg hauv lub tshuab hloov pauv kev ua haujlwm, lub tsheb lub khoos phis tawj tuaj yeem hloov kho kom muaj txiaj ntsig zoo thiab txo qis emissions.
Oxygen Sensors nyob qhov twg?
Txhua lub tsheb tsim tom qab xyoo 1996 yog nruab nrog Oxygen Sensors. Feem ntau cov tsheb muaj ob ntawm cov sensors - ib tug ntws thiab ib tug downstream ntawm txhua catalytic converter. Qee zaum, tshwj xeeb nrog dual-kua V6 thiab V8 xyaw, koj tuaj yeem pom plaub Oxygen Sensors. Nyob rau hauv no configuration, txhua lub txhab nyiaj ntawm lub cav muaj ib tug khub ntawm sensors, kom meej meej tswj cov huab cua-rau-roj piv thiab catalytic converter efficiency.
Oxygen Sensors ua haujlwm li cas?
Oxygen Sensors yog qhov tseem ceeb "ntse" cov khoom siv hluav taws xob ua kom sov. Lub sensor lub taub, tso rau hauv lub tso pa tawm, nta zirconium ceramic noob. Lub teeb no muaj ob sab hauv thiab sab nrauv coated nrog ib txheej ntawm platinum ntxeem tau, uas ua hauj lwm raws li electrodes. Qhov tseem ceeb, sab hauv ntawm lub teeb yog vented rau sab nraud cua los ntawm lub cev sensor.
Thaum raug cov pa hluav taws xob kub, qhov sib txawv ntawm cov pa oxygen ntawm lub teeb thiab cov cua nyob ib puag ncig ua rau muaj qhov sib txawv ntawm qhov sib txawv, tso cai rau tam sim no ntws los ntawm lub teeb. Cov txheej txheem no tsim cov teeb liab uas lub tsheb lub khoos phis tawj siv los kho cov huab cua / roj sib xyaw kom pom kev sib xyaw.
