Car othandizira othandizira


Chothandizira mu dongosolo la utsi lakonzedwa kuti lichepetse kutulutsa kwa zinthu zovulaza mumlengalenga. Ndi mpweya wotulutsa uwasandutsa zinthu zopanda vuto. Chothandizira chimagwiritsidwa ntchito pa injini za mafuta ndi dizilo. Njira zitatu zosinthira othandizira. Amagwiritsidwa ntchito mu injini zamafuta. Imagwira pa kusakaniza kwa stoichiometric, komwe kumatsimikizira kuyaka kwathunthu kwa mafuta. Makina osinthira othandizira atatu amaphatikizapo malo othandizira, kutchinjiriza komanso nyumba. Mtima wa chosinthira chothandizira ndichothandizira, chomwe chimakhala ngati maziko a othandizira. Chonyamulira chimapangidwa ndi ziwiya zoumbaumba zapadera zopangira. Kapangidwe kake, chingwe chothandizira chimakhala ndi magulu azitali zazitali. Izi zimawonjezera kwambiri malo olumikizirana ndi mpweya wotulutsa utsi.

Zothandizira othandizira kusintha


Zinthu zothandizidwa zimagwiritsidwa ntchito pamwamba pamasamba a zisa. Chingwe chochepa kwambiri chomwe chimaphatikizapo zinthu zitatu: platinamu, palladium ndi rhodium. Zothandizira zimathandizira kusintha kwa mankhwala mu neutralizer. Platinamu ndi palladium ndizowonjezera zowonjezera. Amalimbikitsa makutidwe ndi okosijeni a ma hydrocarboni osayaka mpaka nthunzi yamadzi, kuchokera ku carbon monoxide, carbon monoxide mpaka carbon dioxide. Rhodium ndi chothandizira chochepetsera. Izi zimachepetsa nayitrogeni oxides kukhala osavulaza nayitrogeni. Mwanjira imeneyi, othandizira atatuwo amachepetsa zowononga zitatu mu mpweya wa utsi. Mzere wothandizira umakhala mchikwama chachitsulo. Nthawi zambiri pamakhala kutchinjiriza pakati pawo. Pankhani ya neutralizer, chojambulira cha oxygen chimayikidwa. Chofunikira poyambitsa chosinthira chothandizira ndikuti kutentha kumafika 300 ° C. Kutentha koyenera ndi 400 mpaka 800 ° C.

Komwe mungayikitsire chosinthira chothandizira galimoto


Pakutentha kumeneku, 90% yazinthu zoyipa zimasungidwa. Kutentha kopitilira 800 ° C kumayambitsa kusinthana kwazitsulo zopangira zitsulo ndi zotchingira uchi. Chosinthira chothandizira nthawi zambiri chimayikidwa kumbuyo kwakumbuyo kwa utsi kapena kutsogolo kwa chimbudzi. Kukhazikitsa chosinthira koyamba kumathandiza kuti zizitentha msanga. Koma chipangizocho chimakhala ndi matenthedwe ambiri. Poterepa, pamafunika njira zina zowonjezerapo kuti chothandizira chitenthe mwachangu, zomwe zimawonjezera kutentha kwa mpweya wotulutsa utsi. Kusintha nthawi yoyatsira poyenda pang'onopang'ono; kuonjezera ulesi; kusintha kwa nthawi ya valve; jakisoni wamafuta angapo kuzungulira; mpweya kwa dongosolo utsi.

Zomwe zimapatsa dizilo okosijeni


Njira zitatu zothandizira othandizira zimagwiritsidwa ntchito kukonza bwino. Kugawika magawo awiri: chosinthira choyambirira. Zomwe zili kuseri kwa zobwezeretsa zambiri. Chothandizira chachikulu, chomwe chili pansi pa galimotoyo. Chothandizira cha dizilo chimatsimikizira kuti makutidwe amadzimadzi amatulutsa mpweya ndi mpweya. Zomwe zilipo zokwanira m'mipweya yotulutsa dizilo. Mukamadutsa chosinthira chothandizira, zinthu zoyipa za carbon monoxide ndi ma hydrocarboni zimaphatikizidwa ndi zinthu zopanda vuto za carbon dioxide ndi nthunzi yamadzi. Kuphatikiza apo, chothandizira pafupifupi chimathetseratu fungo losasangalatsa la utsi wa dizilo.

Wothandizira othandizira


Kusintha kwa makutidwe ndi mpweya mu chothandizira kumapangitsanso zinthu zosafunikira. Chifukwa chake, sulfure dioxide imakhudzidwa ndi sulfur trioxide. Izi zimatsatiridwa ndi kupanga sulfuric acid. Sulfuric acid gas imaphatikizana ndi mamolekyulu amadzi. Zomwe zimabweretsa mapangidwe olimba a particles - sulphate. Iwo kudziunjikira mu Converter ndi kuchepetsa dzuwa. Kuchotsa sulfa kuchokera pa chosinthira, makina oyang'anira injini amayambitsa njira yowonongera zinthu. Momwe chothandizira chimatenthedwa ndi kutentha pamwamba pa 650 ° C ndikuyeretsedwera ndi mpweya wabwino wambiri. Palibe mpweya mpaka kulibe mpweya. Chothandizira cha dizilo sichigwiritsidwa ntchito pochepetsa mpweya wa NOx m'mipweya yotulutsa. Ntchitoyi imagwiridwa ndi makina a injini ya dizilo. Kutulutsa mpweya wokwanira kapena njira yosinthira othandizira.

Mafunso ndi Mayankho:

Mfundo yoyendetsera ntchito yosinthira mpweya wotulutsa mpweya ndi chiyani? Kuchita kwa mankhwala kumachitika mu chothandizira kutengera kutentha kwambiri komanso kukhudzana kwa nitrogen oxides ndi zitsulo zamtengo wapatali. Zotsatira zake, zinthu zovulaza sizimakhazikika.

Kodi exhaust gas converter ndi chiyani? Ichi ndi chidebe chaching'ono chomwe chimakhala pafupi kwambiri ndi kutulutsa kwa injini. Mkati mwa botololi muli zodzaza zadothi zokhala ndi zisa za zisa zokutidwa ndi zitsulo zamtengo wapatali.

Kodi chosinthira chothandizira chimagwiritsidwa ntchito chiyani? Mbali imeneyi ya dongosolo utsi neutralizes zinthu zoipa mu mpweya utsi ndi kuwasandutsa kukhala zochepa zoipa.

Kodi chosinthira chothandizira chili kuti? Popeza kuti mankhwala opangidwa ndi mankhwala ayenera kuchitika mu chothandizira chifukwa cha kutentha kwapamwamba, mpweya wotulutsa mpweya suyenera kuzizira, choncho chothandizira chimakhala pafupi ndi dongosolo la mpweya wa injini yoyaka mkati momwe zingathere.
