Dizilo particulate Zosefera. Kusankha chipangizo, mfundo opaleshoni

Mawu oyamba a mfundo yatsopano chilengedwe magalimoto kukakamiza opanga kukhala njira zamakono zapamwamba kwambiri kuti athe malonda awo kutsatira mfundo. zokhumba amenewa chifukwa zikamera wa mabanja onse a injini nkhani otsika-umuna mankhwala processing. Ntchito mkati m'madera ena. Choncho, mu 2004 panali dizilo particulate fyuluta kuti minimizes mpweya zoipa. Ngakhale pa nthawi ya penipeni izo sizinali choncho ambiri mwa anthu, kutukula apitiriza kukhala lingaliro, ndipo lero, molingana ndi "Yuro 5" muyezo, kupezeka kwa chipangizo mu kapangidwe galimoto lofunika.

Chifukwa kufunika kwa particulate woganiza?

Zipangizo za mtundu uwu ndi njira aftertreatment mpweya utsi. Mwakucimbidza tisaiwale kuti Zosefera dizilo particulate ntchito injini dizilo yekha. The mayunitsi petulo wa analogue amachita monga chothandizira a. Cholinga chachikulu cha unsembe ndi kuchotsa poizoni ku utsi. Chotero processing mpweya zimapangitsa galimoto zambiri zachilengedwe wochezeka. Zosefera angakhale osiyana pa chipangizo, koma iwo amagwira ntchito kuchepetsa mwaye zili mu ntchito utsi ndi 80%.

Mwatsoka, kukhazikitsa nchito imeneyi kumatanthauza zambiri mavuto ena, ambiri mwa zokhudza kutumikira sefa yokha. Monga zida mafuta processing lavundira ndipo amafuna kuyeretsa. Nthawi kwambiri, Zosefera particulate achotsedwa ndipo anaika mu malo awo zigawo latsopano aftertreatment.

The chipangizo fyuluta

chipika aikidwa pambuyo pa Converter othandizira. Ena Zosefera kulola yofanana osakaniza ake structural ndi makutidwe ndi okosijeni chothandizira. Zikatero izo ili kuseri kwa utsi zobwezedwa, kumene pazipita mpweya kutentha. Waukulu chigawo chimodzi cha masanjidwewo aikidwa mu casing zitsulo. The zitsanzo muyezo zikhale za pakachitsulo carbide, omwe ndi osiyana ndi kukonza ma ochepa njira mtanda gawo. Kwenikweni, kapangidwe porous a mpanda mbali mu njira izi ndi amatipatsa kuyeretsedwa. Chofunika, ndi dizilo particulate fyuluta ndi mbali chabe ya osiyanasiyana lonse la machitidwe ndi zipangizo nawo mayendedwe a. Mu gulu ili kumaphatikizapo masensa kutentha, mphamvu wagawo, kompyuta bolodi, ndi turbocharger ndi T. D. chinthu chinanso chimene sefa amachita komaliza kuyeretsa ntchito choncho tinganene kuti ngati mfundo, kuyambira wonunkha zipangizo zinthu zooneka.

Mfundo ntchito

Dongosolo lonse akhoza kugawidwa mu magawo awiri - ndi kukhazikitsa mwachindunji zosefera ndi mwaye kusinthika. Mu sitepe yoyamba mpweya wakuda particles azunguliridwa, kenako anakaika pa makoma fyuluta. Mu nkhani imeneyi, mabvuto ambiri particles ang'ono mpaka 1 micron, monga wochepa thupi lawo chindiletsa m'ndende. Pamene chiwerengero cha zinthu zoterozo ndi zochepa 5% ya okwana, iwo ali basi owopsa kwa anthu. Komabe, masiku ano Zosefera particulate amakulolani bwino kusamalira ndi processing particles amenewa. Chachiwiri siteji kusinthika uyikidwa zinthu. chakuti kudzikundikira awo lalikulu zedi osati Kukubweretsera masautso yekha sefa, komanso kumachepetsa injini mphamvu monga kupanga chinthu cholepheretsa ndime ya mpweya lotsatira. Pa nkhani imeneyi, mitsuko kuyeretsa mwaye zamakono zili mbali kuvomerezedwa utumiki galimoto.

Chabe fyuluta kuyeretsa

Mtundu wa chithandizo kuti akuyendera chifukwa kutentha utsi mpweya angafikire 600 ° C. mtundu wina wa njira chabe kubadwanso kuti atchule zina zosiyanasiyana mu mafuta kuonetsetsa kuyaka imayenera mwaye. Pankhaniyi alipo ndi chikoka cha kutentha, koma pa mlingo wa 400-500 ° C. Track mode zimathandiza ikukhudzana zotsatira kachipangizo particulate fyuluta, amene akulamulira ndi ena mwa magawo a injini. Komabe, mu zinazake galimoto opaleshoni, kungokhala chete zosefera chilibe ntchito kapena zosatheka.

Yogwira fyuluta kuyeretsa

Njira imeneyi amakakamizidwa kutsuka sefa, ozikidwa pa mkulu kutentha malo apadera utsi mpweya. KUCHULUKA kukhalabe wotere mwaye pang'onopang'ono kudyedwa. Zofunika yogwira kuyeretsa - njira imene imafika kutentha. Mwa njira ambiri n'kopanda mochedwa jekeseni mafuta, mwa kundipatsako kwa dizilo utsi sitiroko ndi Kutentha ndi microwaves. Nthawi zina, kukonza dizilo tinthu fyuluta ndi kubala chotenthetsera magetsi. chipangizo akhoza anaika pafupi ndi chipangizo kuyeretsa, koma isanafike kasinthidwe ichi tiyenera kuziganizira mofatsa kuwayika zigawo zake. yogwira kuchira amadziwikanso anakwanitsa mothandizidwa ndi masensa - makamaka, zida ndi ntchito kuyeza kuthamanga ndi kutentha.

Kodi kuchotsa particulate woganiza?

Ngakhale kuti kachitidwe kamakono kuyeretsedwa, Zosefera wa mtundu uwu posapita nthawi anayamba kusokoneza ntchito injini. Zimenezi ndi zimenenso mwaye accumulations kuti si kuchotsedwa njira anapereka. The linanena bungwe la zinthu zimenezi zingakhale dismantling chipangizo. Ndipo chochitika imagwiridwa ndi mbali ziwiri. Woyamba ntchito Buku imagwiridwa, imene ankaiphwasula mwachindunji particulate fyuluta. Mtengo wa ndondomeko zimasiyanasiyana 7 mpaka 12 chikwi. Opaka. Mwa njira, unsembe wa fyuluta watsopano pafupifupi 30-40 zikwi. Opaka. Choncho ochepa angayerekeze kumaliza kulenganso dongosolo kuyeretsa. Sitepe yachiwiri tichipeza mu kuchotsa mapulogalamu chipangizo ndi rewriting injini ulamuliro unit.

Pomaliza

mfundo zachilengedwe kutukula poyerekezera ndi magalimoto, ndithudi, amasamala za tsogolo la anthu ndi kufunafuna alimi Asia malangizo a woganizira kwambiri mawu a zimakhudza chilengedwe. Chomaliza mankhwala a mwa malo awa ndi kukhala particulate Zosefera kuti kuchepetsa amadza oipa chilengedwe. Pochita zimenezi, ziziyenda ali pamodzi ndi unsembe watsopano mavuto ambiri. Wokwanira kutchula kufunika kwa polojekiti zonse mtima kwa sefa kusinthika. Mu nkhani ya osakwanira zipangizo kudziletsa kuyeretsa mwini galimoto sangachitire mwina koma kuchotsa njerwa kapena m'malo izo ndi fyuluta latsopano. Koma nthawi zonse mtengo adzakhala mosalephera.
