Yog tias EGR system yog txhaws up, lub valve yog daig kaw, combustion kub nce. Qhov no tej zaum yuav ua rau pinging (detonation), nrog rau surging ntawm lub teeb acceleration. Hauv lub cav diesel, qhov tsis zoo EGR valve yog ib qho ua rau muaj pa taws dub. Lub teeb Check Engine kuj tuaj yeem tshwm sim hauv ob qho tib si.
Hauv qhov no, ua li cas yog tias EGR valve raug thaiv?
Yog tus EGR valve yog txhaws los yog kiag li thaiv tawm nws tuaj yeem rov hlawv teeb meem emissions nyob rau hauv lub combustion chamber. Cov NOx emissions yuav ntws los ntawm cov combustion chamber thiab tawm ntawm cov yeeb nkab. Kev tso pa NOx ntau dhau yuav tshwm sim thaum kuaj pom huab cua thiab ua rau tsis ua haujlwm.
Tom qab ntawd, lo lus nug yog, dab tsi yuav kaw EGR valve ua? Thaum lub EGR valve yog daig qhib, txhais tau hais tias tag nrho cov pa yuav yuav rerouted rau lub combustion chamber, uas txhais tau hais tias muaj yuav ua pa me me uas yog qhov xav tau rau kev hlawv. A valve yog daig kaw: ntawm qhov kawg ntawm qhov spectrum, koj ua tau kuj muaj a valve uas kaw thiab yuav tsis qhib.
Ib yam li ib tus tuaj yeem nug, cov tsos mob ntawm qhov tsis ua haujlwm EGR valve yog dab tsi?
Rough idle Ib qho ntawm feem ntau tsos mob ntawm teeb meem nrog lub tsheb EGR valve yog qhov ua tsis ncaj. Nws tsis yooj yim rau EGR li qub mus rau qhov tsis ua haujlwm thiab ua nyam hauv txoj haujlwm qhib. Qhov no tuaj yeem ua rau cov pa roj rov qab los rov tshwm sim ua rau tsis ua haujlwm hnyav txawm tias qhov xwm txheej tsis xav tau.
Koj puas tuaj yeem tsav nrog EGR valve tsis zoo?
Ib daig EGR valve tuaj yeem ua tau ua rau lub cav ping, thiab qhov ntawd yuav sai rhuav nws. Raws li cov teeb meem kev ua haujlwm koj piav, nws suab zoo li tus EGR valve pintle occationally sticks hauv qhov chaw qhib. EGR feem ntau yuav tsum tsuas yog siv qhov chaw qis, kev loj ceev tsav tsheb tej yam kev mob
