Dab tsi yog cov khoom ntawm lub cav tso pa tawm
Sau cov pa tso rau hauv txhua lub tog raj kheej ntawm lub cav, txo cov suab nrov, tshem tawm cov nplaim hluav taws thiab cov pa taws hauv cov pa tawm, thiab ntxuav cov khoom tsis zoo hauv cov pa tawm, kom cov pa tso pa tawm mus rau qhov chaw nyab xeeb. Nyob rau tib lub sijhawm, nws tseem tuaj yeem tiv thaiv dej los ntawm lub cav thiab tiv thaiv lub cav.
[cov khoom muaj pes tsawg leeg ntawm lub cav tso pa system]: tso pa tawm manifold, peb-txoj kev catalytic converter, oxygen sensor thiab muffler
[kev ua haujlwm ntawm ntau yam khoom ntawm lub cav tso pa tawm]: 1. Cov pa tawm manifold:
Nws txuas nrog lub cav lub tog raj kheej thaiv kom pom tseeb cov pa pa hauv txhua lub tog raj kheej mus rau qhov tso pa tawm.
2. Peb txoj kev catalytic converter:
Cov pa phem xws li HC, CO thiab NOx (nitrogen oxides) hauv lub tsheb tso tawm tau hloov mus rau cov pa roj carbon dioxide, dej thiab nitrogen los ntawm oxidation thiab txo qis.
3. Oxygen sensor:
Cov huab cua-roj piv cov teeb liab ntawm qhov sib tov yog tau los ntawm kev kuaj xyuas cov ntsiab lus ntawm cov pa oxygen ions hauv cov pa tawm, uas tau hloov mus rau hauv cov teeb liab hluav taws xob thiab cov tswv yim rau hauv ECU. Raws li cov teeb liab no, ECU kho lub sijhawm txhaj tshuaj kom paub txog huab cua-roj piv cov lus tawm tswv yim tswj, kom lub cav tuaj yeem tau txais qhov sib xyaw ua ke zoo tshaj plaws, txhawm rau txo cov pa phem thiab txhim kho roj kev lag luam. (feem ntau yog ob, ib qho tom qab lub tso pa tawm thiab ib qho tom qab peb-txoj kev catalyst. Nws lub luag haujlwm tseem ceeb yog xyuas seb lub catalyst peb-txoj kev tuaj yeem ua haujlwm li cas.)
4. Silencer:
Txo cov suab nrov. Lub twj tso kua mis tau nruab rau ntawm qhov hluav taws xob ntawm cov yeeb nkab tso kom ua kom cov pa pa nkag mus rau hauv qhov chaw tom qab ua kom ntsiag to. Feem ntau, 2 ~ 3 silencers raug saws. (lub muffler pem hauv ntej yog [resistive muffler], uas yog siv los nqus cov suab nrov nrov; lub hauv qab muffler (lub ntsiab muffler) yog [resistant muffler], uas yog siv los txo cov suab nrov tsawg.
