Cov pa roj carbon emissions tsuas yog unburned roj yog pumped raw rau hauv lub tso pa system. Misfiring yog qhov feem ntau yuav ua txhaum, thiab qhov ntawd tuaj yeem los ntawm qhov teeb meem ignition, los yog lub cav tsis ua haujlwm uas txo qis compression.

Ib yam li ntawd, koj yuav nug, dab tsi ua rau cov pa roj carbon ntau tso tawm?

Lean Fuel Mix - Txhua yam mob uas yuav ua ua rau huab cua tsis ntsuas kom nkag mus rau hauv qhov sib nqus, thiab thaum kawg cov chav sib txuas, yuav ua rau muaj cov pa roj carbon ntau ( HC ). Tus mob no hu ua lean miss-fire. Cov kev ua yuam kev xws li lub tshuab nqus tsev nqus dej thiab lub gasket yuav xau ua rau sib xyaw roj/cua sib tov.

Ib tug kuj yuav nug, dab tsi ua rau tsis muaj hluav taws xob hydrocarbons? Hydrocarbons tsis tawg (UHCs) yog cov hydrocarbons tso tawm tom qab roj av tau hlawv hauv lub cav. Thaum twg tsis hlawv roj yog emitted los ntawm ib tug combustor, lub emission yog ua los ntawm roj "kev zam" cov nplaim taws. Qee zaum lo lus "cov khoom lag luam ntawm kev sib txuas tsis tiav," lossis PICs, tau siv los piav txog hom tsiaj no.

Kuj nug, HC tso pa tawm yog dab tsi?

Cov pa tawm ntawm ntau cov pa phem tau pom tias muaj ntau yam tsis zoo rau pej xeem kev noj qab haus huv thiab ib puag ncig ib puag ncig. Cov pa tawm uas yog cov pa phem tseem ceeb ntawm kev txhawj xeeb suav nrog: Hydrocarbons ( HC ) - Ib chav kawm ntawm cov hluav taws kub hnyiab los yog ib nrab hlawv, hydrocarbons yog co toxins.

Koj yuav kho qhov teeb meem tso pa tawm li cas?

Yuav Kho Li Cas Teeb Meem Ntawm Lub Tsheb

  1. Tshawb xyuas lub tshuab lim cua ntawm lub tshuab ntxhua khaub ncaws.
  2. Txheeb xyuas Qhov Zoo Crankcase Ventilation (PCV).
  3. Txheeb xyuas qhov Kev Tswj Evaporative Emissions Control (EVAP).
  4. Mus hla Exhaust Gas Recirculation (EGR) system.
  5. Txheeb Xyuas Lub Tshuab Txhaj Tshuaj Yog tias koj tus qauv tsheb tshwj xeeb tau nruab nrog nws.
