Cov lus xaus yog los ntawm Emission Analytics, ib lub koom haum ywj pheej uas ua cov kev ntsuas emissions ntawm cov tsheb nyob rau hauv cov xwm txheej tiag tiag. Tom qab ob peb qhov kev ntsuam xyuas, nws tau xaus lus tias cov pa paug vim cov log tsheb hnav, thiab los ntawm cov brakes, tuaj yeem ua 1000 npaug siab dua li cov ntsuas hauv cov pa roj ntawm peb lub tsheb.
Nws paub zoo tias cov pa phem phem npaum li cas rau tib neeg kev noj qab haus huv (mob hawb pob, mob ntsws cancer, teeb meem plawv, kev tuag ntxov), tawm tsam qhov uas peb tau pom qhov nruj nruj ntawm cov qauv emissions - yog li, niaj hnub no qhov dav feem ntau cov tsheb lag luam tuaj nrog cov lim dej.
Tab sis yog hais tias cov pa emissions tau nce nruj me ntsis tswj, qhov qub tsis tshwm sim nrog cov pa paug uas tshwm sim los ntawm cov log tsheb hnav thiab siv cov brakes. Hauv kev muaj tiag tsis muaj kev cai.
Thiab nws yog ib qho teeb meem ib puag ncig (thiab kev noj qab haus huv) uas tau nce zuj zus zuj zus, vim yog (tseem loj hlob) kev vam meej ntawm SUVs, thiab tseem muaj kev muag khoom ntawm cov tsheb fais fab. Vim li cas? Tsuas yog vim tias lawv hnyav dua li cov tsheb sib npaug - piv txwv li, txawm tias nyob hauv cov tsheb loj, muaj qhov sib txawv ntawm 300 kg ntawm cov uas nruab nrog lub tshuab hluav taws xob sib xyaw thiab cov tshuab hluav taws xob.
Cov khoom
Particles (PM) yog ib qho sib xyaw ntawm cov khoom siv thiab cov tee dej uas muaj nyob hauv huab cua. Qee qhov (plua plav, pa taws, soot) tuaj yeem loj txaus pom nrog lub qhov muag liab qab, thaum lwm tus tsuas tuaj yeem pom nrog lub tshuab ntsuas hluav taws xob. PM10 thiab PM2.5 xa mus rau lawv qhov loj me (inch), feem, 10 micrometers thiab 2.5 micrometers lossis me dua - cov plaub hau strand yog 70 micrometers inch, rau kev sib piv. Raws li lawv me me, lawv nqus tau thiab tuaj yeem nkag mus rau hauv lub ntsws, ua rau muaj teeb meem kev noj qab haus huv loj.
Cov pa paug uas tsis yog pa tawm - paub ua lus Askiv li SEN lossis Non-Exhaust Emissions - twb suav hais tias yog feem ntau tawm los ntawm kev thauj mus los: 60% ntawm tag nrho PM2.5 thiab 73% ntawm tag nrho PM10. Ntxiv nrog rau cov log tsheb hnav thiab nres hnav, cov khoom siv no tuaj yeem tshwm sim los ntawm kev hnav khaub ncaws sab nraud nrog rau kev tshem tawm ntawm txoj kev plua plav los ntawm cov tsheb hla saum npoo av.
Emissions Analytics tau ua tiav qee qhov kev ntsuam xyuas cov log tsheb ua ntej, tau siv cov kev sib txuas uas paub zoo (ob chav-pob lub cev) nruab nrog cov log tsheb tshiab thiab nrog lub siab raug. Kev ntsuam xyuas tau qhia tias lub tsheb tso tawm 5.8 g / km ntawm cov khoom siv - piv nrog 4.5 mg / km (milligrams) ntsuas hauv cov pa pa. Nws yog qhov sib npaug ntau dua 1000.
Qhov teeb meem yog yooj yim aggravated yog hais tias lub log tsheb muaj ib tug siab hauv qab no zoo tagnrho, los yog txoj kev nto yog abrasive ntau, los yog txawm, raws li Emissions Analytics, cov log tsheb yog cov pheej yig tshaj; siv tau scenarios nyob rau hauv cov xwm txheej tiag.
Particle emission daws teeb meem?
Emission Analytics suav tias yog qhov tseem ceeb uas yuav tsum muaj, thawj qhov chaw, kev tswj hwm ntawm cov ncauj lus no, uas tam sim no tsis muaj.
Sau npe yuav mus rau peb tsab ntawv xov xwm
Nyob rau hauv lub sij hawm luv luv, qhov kev pom zoo yog txawm mus yuav cov log tsheb zoo tshaj plaws thiab, ntawm chav kawm, saib xyuas lub log tsheb siab, ua kom nws ua raws li qhov tseem ceeb uas tau pom zoo los ntawm hom rau lub tsheb hauv nqe lus nug. Txawm li cas los xij, nyob rau lub sijhawm ntev, nws yog qhov tseem ceeb uas qhov hnyav ntawm lub tsheb peb tsav txhua hnub kuj txo. Ib qho kev sib tw loj zuj zus, txawm tias qhov tshwm sim ntawm kev siv hluav taws xob ntawm lub tsheb thiab nws cov roj teeb hnyav.
