Hloov EGR valve - ntawm no yog li cas!
Txheem
Lub npe EGR valve ua haujlwm tseem ceeb hauv lub tsheb. Peb yuav qhia koj yuav ua li cas paub txog qhov ua tsis tiav EGR valve, yuav hloov lub valve li cas, thiab cov nqi dab tsi koj yuav xav tau.
Txawm li cas los xij, yog tias nws ua tsis tiav, nws tsis tuaj yeem ua txoj haujlwm no ntxiv lawm. Qhov no tuaj yeem cuam tshuam rau kev ua haujlwm ntawm lub cav nrog rau nws txoj sia. Vim li no, EGR valve tsis xws luag yuav tsum tau kho sai sai.
EGR valve ua cov haujlwm hauv qab no
Diesel thiab roj av cav muaj combustion kub mus txog 2500 degrees Celsius .
Yog li tsim nitrogen oxides, uas tsim kev puas tsuaj rau ib puag ncig thiab yuav tsum tau muab tshem tawm ntawm lub cav. uas txo tus nqi ntawm nitrogen oxides tawm mus rau hauv ib puag ncig, ib feem ntawm cov pa pa tawm rov qab mus rau cov khoom noj khoom haus los ntawm thiaj li hu ua exhaust gas recirculation (EGR) system .
Cov txheej txheem no ho txo qhov kub thiab txias combustion thiab yog li tsawg nitrogen oxides yog tsim los ntawm cov txheej txheem.
Hauv txheej txheem no EGR valve ntsuas tus nqi ntawm cov pa roj rov qab mus rau lub cav. Yog tias EGR valve tsis tuaj yeem ua nws txoj haujlwm ntxiv lawm vim muaj qhov tsis xws luag, hauv cheeb tsam Lub taub hau kheej kheej los yog lub turbocharger soot deposits accumulates, uas yuav txo tau lawv cov kev pab cuam lub neej.
Cov tsos mob no qhia txog kev ua haujlwm tsis zoo
Raws li cov ntaub ntawv nrog ntau lub tsheb tseem ceeb, Ntau cov tsos mob tuaj yeem qhia tau tias EGR valve tsis raug .
Txawm li cas los xij, qee yam ntawm cov tsos mob no tej zaum kuj yog cov cim qhia ntawm lwm yam tsis xws luag . Yog tias koj pom cov tsos mob zoo li no, koj yuav tsum tau saib xyuas lwm cov tsos mob kom koj thiaj li yooj yim cais qhov kev puas tsuaj.
Cov tsos mob ntawm qhov ua tsis tiav EGR valve suav nrog:
| - Lub tsheb jerks thaum tsav tsheb. - Lub cav fais fab raug txo. - Tsis tshua muaj zog ntawm tag nrho throttle. - Lub cav mus rau hauv hom xwm txheej ceev hauv qab thauj khoom. - Lub tshuab kuaj xyuas lub teeb tuaj luv luv thaum lub cav pib lossis thaum tsav tsheb. - Muaj ntau cov pa taws tsaus nti tawm ntawm cov pa tso pa tawm. - Muaj kev siv roj ntau ntxiv. - Kev ntsuas siab nitrogen oxide emissions yog ntsuas thaum lub sij hawm tso tawm emissions. |
Yog tias muaj cov tsos mob tshwm sim, EGR valve yuav tsum tau kho lossis hloov sai li sai tau. Rau lub hom phiaj ntawm ib puag ncig thiab koj lub tsheb.
