Kev tu thiab hloov cov catalytic converter yog ib txoj hauv kev nyiam los daws cov teeb meem ntawm cov pa. Lub catalytic converter, raws li lub hauv paus ntaus ntawv rau purifying pa emissions, yog hais tias malfunctioning, yuav ua rau ineffective purification ntawm pa pa gases, ua rau emissions tshaj cov qauv. Kev tu tsis tu ncua los yog hloov cov catalytic converter tshiab tuaj yeem txhim kho qhov zoo ntawm cov pa emissions.
Kev ntxuav thiab hloov lub txim hluav taws xob kuj tseem yog cov kev daws teeb meem tseem ceeb:
Kev siv lub tshuab hluav taws xob ntev ntev tuaj yeem ua rau muaj qhov tshwm sim xws li cov pa roj carbon deposits thiab yaig, yog li cuam tshuam rau lawv cov txiaj ntsig thiab ua rau muaj kuab paug ntau dua. Los ntawm kev ntxuav lossis hloov cov pob hluav taws xob, qhov teeb meem ntawm cov pa tawm ntau dhau tuaj yeem daws tau zoo.
Tsis tas li ntawd, kev kuaj xyuas cov pa oxygen sensors yog qhov tseem ceeb heev. Cov pa oxygen sensors tau muab faib ua cov dej ntws thiab cov dej ntws, thiab lawv txoj haujlwm muaj feem cuam tshuam txog kev kuaj xyuas cov pa roj carbon monoxide hauv tsheb sib tsoo thiab ua kom huv. Tej kev puas tsuaj los yog carbon buildup ncaj qha cuam tshuam rau cov pa emissions. Yog li ntawd, tsis tu ncua kev tshuaj xyuas thiab tu cov pa oxygen sensors yog ib qho ntawm cov kev ntsuas tsim nyog los tswj cov pa roj pa kom zoo.
Kev ua kom tiav kev tu lub cav ntawm lub cav kuj yog ib txoj hauv kev zoo rau kev daws cov teeb meem tso pa tawm. Los ntawm kev ntxuav cov khoom xws li cov roj hluav taws xob, cov khoom siv hluav taws xob, thiab lub qhov hluav taws xob valve, kev ua haujlwm ntawm tag nrho lub zog hluav taws xob tuaj yeem txhim kho tau zoo, yog li txhim kho qhov zoo ntawm cov pa emissions.
Nyob rau hauv lub neej txhua hnub, ntxiv nrog rau cov hau kev saum toj no, kev tswj xyuas kev tsav tsheb zoo thiab kev saib xyuas tsis tu ncua yog qhov tseem ceeb sib npaug. Xaiv cov roj av zoo, ua tib zoo saib xyuas tus cwj pwm ntawm kev tsav tsheb, thiab tshuaj xyuas lub tsheb tsis tu ncua, cov kev ntsuas yooj yim no tuaj yeem tsis tsuas yog txhim kho cov pa emissions tab sis kuj txhim kho tag nrho cov kev ua tau zoo thiab kev nyab xeeb ntawm lub tsheb.
