Puas yog lub tshuab tso pa txo cov pa phem?
Vim tias koj lub tsheb lub cav khiav ntawm combustion (kub roj av), nws tsim cov pa luam yeeb. Cov pa taws no yuav tsum tau muab tshem tawm ntawm lub cav kom lawv tsis txhob tua hluav taws thiab yuav tsum tau khaws cia kom deb ntawm qhov rooj thiab qhov rais raws li qhov ua tau vim muaj cov pa roj carbon monoxide siab. Koj cov pa tawm kuj tseem muaj cov kab mob ntawm ntau lwm yam tshuaj, qee qhov ua paug rau ib puag ncig. Koj qhov chaw tso pa tawm yog tsim los txo cov pa phem.
Yam twg?
Ua ntej, nkag siab tias feem ntau ntawm koj cov pa tawm tsuas yog txhais tau tias thauj cov pa pa tawm ntawm ib qho chaw (lub cav) mus rau lwm qhov (muffler). Koj cov pa tawm manifold, downpipe, yeeb nkab A, yeeb nkab B thiab muffler tsis muaj dab tsi cuam tshuam nrog kev txo qis emissions. Tag nrho cov ntawm lawv yog tsom rau tshem tawm cov pa roj los ntawm lub cav tsis pub koj thiab koj cov neeg caij tsheb mus rau lawv. Lub muffler txoj haujlwm nkaus xwb yog muffle lub suab ntawm cov pa.
Yog li qhov twg yog lub luag haujlwm rau kev txo qis emissions? Koj tuaj yeem ua tsaug rau koj li EGR valve thiab catalytic converter. Lub EGR (exhaust gas recirculation) valve directs cov pa roj rov qab los ntawm lub combustion chamber, tov nrog cov huab cua ntshiab, kom hlawv ntau cov khoom (qhov no kuj txhim kho roj kev lag luam los ntawm kev hlawv cov roj av tsawg tshaj plaws uas tsis tau hlawv thaum pib combustion).
Txawm li cas los xij, koj lub catalytic converter yog lub hnub qub tiag tiag ntawm cov yeeb yam. Nws zaum ntawm koj ob lub kav dej thiab nws txoj haujlwm tsuas yog kom sov. Nws tau kub heev uas nws hlawv tawm feem ntau ntawm cov pa phem uas yuav tawm los ntawm cov muffler thiab ua paug rau huab cua.
Tom qab tag nrho, koj lub tshuab tso pa tawm yog qhov zoo heev ntawm kev txiav cov tshuaj phem uas tuaj yeem ua rau ib puag ncig (txawm tias nws tsis yog 100% zoo thiab degrades dhau sijhawm, uas yog vim li cas kev kuaj emissions tseem ceeb heev).
