Dab tsi yog Cov Txheej Txheem Kev Ntsuas Rau Cov Dej Haus Catalytic Converters?
Kev tshuaj xyuas qhov muag:Tshawb xyuas cov pa hluav taws xob catalytic converter rau kev puas tsuaj thiab overheating thaum tsav tsheb. Tom qab nqa lub tsheb, tshuaj xyuas lub catalytic converter nto rau dents. Pom tseeb dents thiab khawb qhia tias muaj peev xwm puas tsuaj rau lub catalytic converter cab kuj. Saib xyuas lub tsev nyob rau hauv catalytic converter rau cov pob tawg loj heev los yog xiav me ntsis -cov cim liab. Txheeb xyuas qhov pom pom qhov tsaus grey me ntsis nyob hauv nruab nrab ntawm lub catalytic converter tiv thaiv npog; cov no qhia tias lub catalytic converter tau overheated thiab yuav tsum tau soj ntsuam ntxiv.
Back Pressure Test:Laum ib lub qhov ntawm qhov chaw tsim nyog ntawm cov yeeb nkab tso pa ntawm lub hauv ntej ntawm cov pa hluav taws xob catalytic converter thiab txuas lub ntsuas ntsuas siab. Pib lub cav thiab ntsuas cov pa rov qab siab ntawm idle thiab 2500 rpm. Yog hais tias qhov tso tawm rov qab siab tsis tshaj lub cav qhov kev txwv, lub catalytic converter cab kuj tsis thaiv.
Vacuum Test:Txuas lub tshuab nqus tsev vacuum mus rau qhov nqus manifold, pib lub cav, thiab maj mam nce nws qhov nrawm ntawm qhov tsis ua haujlwm mus txog 2500 rpm. Saib xyuas cov kev hloov pauv hauv lub tshuab nqus tsev vacuum. Yog tias lub tshuab nqus tsev poob ntawm qhov no, ua kom lub cav ceev ntawm 2500 rpm. Yog tias lub tshuab nqus tsev nyeem ntawv poob qis heev tom qab ntawd, nws qhia tau tias cov pa hluav taws xob hloov pauv tau raug thaiv.
