Kuyeretsa kwa DPF - momwe mungasamalire zosefera?

Monga mukudziwa, zosefera DPF anayamba kuikidwa pa magalimoto chifukwa cha kukhazikitsidwa kwa miyezo kawopsedwe mpweya mpweya. Chinthu china chinali cholinga cha malamulo omwe adakhazikitsidwa mu 2001. Izi ndi tinthu tating'ono ta kaboni kapena sulfate zomwe zili mbali ya mpweya wotulutsa mpweya. Kutulutsa kwawo mochulukira sikuli bwino kwa chilengedwe ndipo kumathandizira kupanga khansa. Chifukwa chake, pamagalimoto okhala ndi injini ya dizilo, mulingo wa zinthu wachepetsedwa kuchokera ku 0,025 g mpaka 0,005 g pa km. Chifukwa cha kukhazikitsidwa kwa malamulo atsopano, kuyeretsa zosefera za DPF kwakhala ntchito wamba pafupifupi m'maiko onse aku Europe.

Kubadwanso kwa DPF - kuyaka kowuma ndi konyowa pambuyo pake

Ntchito ya zosefera ndikuyeretsa mpweya wotulutsa kuchokera ku tinthu tolimba. Regeneration DPF (chidule cha DPF - English. particulate fyuluta), kapena kuyeretsa, izi ndi zomwe zimatchedwa "zouma" pambuyo poyaka moto, zomwe nthawi zambiri zimachitika pa kutentha kwambiri. Kutentha kumatha kufika 700 ° C popanda kugwiritsa ntchito madzi owonjezera. Makampani ena opanga magalimoto amagwiritsa ntchito njira ina. Mitundu monga Citroën ndi Peugeot imagwiritsa ntchito catalytic fluid. Izi zimachepetsa kutentha kwa 300 ° C. Zosefera "zonyowa" (FAP - fr. fyuluta yamagulu) amagwira ntchito bwino m'matauni.

Nchiyani Chimayambitsa DPF Yotsekeka?

Kuyambitsa zosefera kuti zigwiritsidwe ntchito kuyenera kuti kuphatikizepo kuwunika bwino ntchito yawo. Zinali zofunikira kudziwa zomwe zimayambitsa kutsekeka kwawo. Chifukwa cha izi, zinali zotheka kupeza njira zothetsera DPF. Vuto lalikulu la DPF ndi FAP linali, ndithudi, mikhalidwe yakumatauni chifukwa cha kuchuluka kwa mpweya wotulutsa mpweya. M’matauni, mpweya umakhala woipitsitsa chifukwa cha kuchuluka kwa magalimoto ndi mafakitale amene amatulutsa zinthu zowononga. 

Njira zazifupi zamatawuni zinalinso vuto. Ndi pa iwo kuti zosefera zowuma sizingafikire kutentha koyenera komwe kuyaka kumatha kuchitika. Zotsatira zake, zosefera zimakhala zotsekedwa ndi tinthu tating'ono tomwe sitingawotchedwe. Pachifukwa ichi, m'pofunika kuyeretsa fyuluta ya particulate, makamaka pamtengo wotsika kwambiri. Mukhoza kusankha pakati pa kuyeretsa kapena kusintha fyuluta. Kumbukirani, komabe, kuti nthawi zambiri kugula kwatsopano, ngakhale m'malo mwake, kungawononge ndalama zambiri za zloty. Ndikoyenera kulingalira chisankho choterocho ndikugwiritsa ntchito malingaliro a akatswiri odziwa bwino magalimoto.

Particulate fyuluta kutopa - mtengo

Nthawi zambiri amakhulupirira kuti ngakhale fyuluta ya particulate ikugwira ntchito mokwanira imafuna ndalama zina. Kukhalapo kwa tinthu tating'ono m'galimoto kumatha kuwononga kuchuluka kwamafuta omwe amawotchedwa. Chodabwitsa ichi nthawi zambiri chimachitika pamene fyulutayo yatsekedwa kale kwambiri. 

Zizindikiro zodziwika bwino za fyuluta yotsekeka ndikuchepetsa magwiridwe antchito agalimoto komanso kuchuluka kwamafuta. Ndizotheka kuti pokhapo mudzakhala ndi chidwi ndi zomwe DPF ikuwotcha ndi pamtengo wanji ntchitoyo imaperekedwa. Mitengo idzakhala yokwera ngati mutasankha kugwiritsa ntchito mafuta apamwamba omwe amasinthidwa pafupipafupi. Chifukwa chake, mutha kuchedwa kuyeretsa DPF, koma chikwama chanu chidzavutika.

Kuwotcha tinthu ta DPF mukuyendetsa

Ngati mukufuna kuchedwetsa kuyeretsa DPF yanu, pali njira zambiri zotsimikiziridwa zomwe mungagwiritse ntchito. Ngati mumagwiritsa ntchito galimoto yanu makamaka m'matauni, ndikofunikira kupita kunja kwatawuni nthawi ndi nthawi. Njira yayitali imakupatsani mwayi wofikira kutentha komwe kumafunikira. Izi zidzalola fyuluta kuwotcha tinthu tating'ono tomwe takhazikikapo. Kuwotcha kwawo kumalimbikitsidwanso ndi opanga. Opanga zigawo amalangiza kuyeretsa nthawi zonse kwa fyuluta ya tinthu tating'onoting'ono. Nthawi zambiri, moyo wautumiki wa zinthuzi umawerengedwa poganizira njira zazitali, osati maulendo afupiafupi kuzungulira mzindawo.

Inde, mungakhale mukudabwa kuti ndi kangati mukufuna kugwiritsa ntchito kuwotcha koteroko. Zimatengera mtundu wa fyuluta yomwe muli nayo komanso momwe mungagwiritsire ntchito. Amakanika nthawi zambiri amalangiza kuchita izi kamodzi pamwezi. Ulamuliro wonse - pambuyo pakutopa koteroko, yesetsani kusapitilira 1000 km. Kumbukirani kuti njira yanu yoyendetsera galimoto ilibe kanthu. Kafukufuku akuwonetsa kuti mukamathamanga mwamphamvu pa liwiro lotsika la injini, tinthu tambiri tosawotchedwa timakhalabe mumipweya yotulutsa mpweya. Mukhozanso kuchepetsa chiwerengero chawo ndi kukonzekera kwapadera.

Kodi mungayeretse bwanji DPF nokha?

Zowonadi, monga madalaivala ena ambiri, nthawi zambiri mumadabwa momwe mungayeretsere zosefera nokha. Utumiki woterewu umaperekedwa mu kuchuluka kwa ntchito zamagalimoto. Tsoka ilo, izi zikutanthauza kusokoneza mapangidwe a fyuluta ndi chiopsezo cha kuwonongeka kwa izo. Ngati mukukayikira izi, mutha kusankha kutsitsa DPF popanda kusokoneza. Pankhaniyi, ntchito yovuta kuchotsa fyuluta sikufunika. 

Mutha kuyeretsa nokha sefa ya particulate. Zomwe muyenera kuchita ndikugula mankhwala oyenera. Thirani madzi osinthika mu fyuluta yozizira. Mankhwala ogwiritsidwa ntchito bwino amawotcha dothi osagwira ntchito. Ndikoyenera kufunsa za kugula mankhwalawa ndi makina odziwa zambiri.

Zosefera za dizilo zimachotsa zinthu zovulaza pamipweya yagalimoto. Kumbukirani kusamalira kusamalira koyenera kwa fyuluta ya DPF. Chifukwa cha izi, mudzakulitsa kuyendetsa bwino kwanu ndikusamalira chilengedwe.
