Lub EGR valve yog lub plawv ntawm lub cav tso pa tom qab kev kho mob. EGR luv luv rau Exhaust Gas Recirculation, thiab qhov ntawd yog qhov nws ua. Cov cuab yeej zoo ib puag ncig zoo tshaj plaws no qhib ntawm qee lub cav ua haujlwm thiab tso cai rau cov pa pa tawm rov qab los ntawm lub cav zaum ob. Cov txheej txheem no ua rau txo qis cov pa phem ntawm nitrogen oxides (NOx), uas ua rau muaj kev tsim cov smog. Hauv tsab xov xwm no, koj yuav pom cov ntaub ntawv hais txog kev ua haujlwm ntawm EGR valve, nrog rau yuav ua li cas ntxuav lub valve thiab vim li cas nws thiaj li yuav tsum tau ntxuav lossis hloov ntau zaus.
EGR valve ua lub neej nyuaj. Nyob rau hauv qhov tseeb, nws yog tej zaum ib qho ntawm feem complex qhov chaw ntawm ib tug niaj hnub engine. Nws raug txim tas li nrog qhov kub siab tshaj plaws uas lub tsheb tuaj yeem tsim thiab txhaws nrog cov khoom ntawm cov roj uas tsis tau hlawv, zoo dua lub npe hu ua carbon. Lub EGR valve yog qhov tsim nyog txaus los tswj los ntawm lub tshuab nqus tsev lossis lub computer, thaum muaj peev xwm tiv taus 1,000-degree carbon-laden tso pa kub txhua zaus lub cav khiav. Hmoov tsis zoo, muaj kev txwv rau txhua yam, suav nrog EGR valve.
Tom qab ntau txhiab lub voj voog, cov pa roj carbon pib tso nyiaj tso rau hauv EGR valve, txwv lub valve lub peev xwm los ua nws txoj haujlwm raws li tus neeg saib xyuas EGR. Cov pa roj carbon deposits tau loj dua thiab loj dua kom txog thaum EGR valve tsis ua haujlwm zoo. Qhov no tuaj yeem ua rau muaj ntau yam kev daws teeb meem, tsis muaj qhov xav tau.
