Kodi ndizotheka kuthetsa zinyalala zamafuta a injini powasintha

Pafupifupi mwini galimoto aliyense amachita mantha komanso amanjenjemera kwambiri mafuta a galimoto akatsika. Kupatula apo, izi zikuwonetsa kusayenda bwino kwa injini ndi kukonza mtsogolo. Choncho, dalaivala ayenera kuyang'anitsitsa mlingo kuti asawononge ndalama zambiri.

Kodi mafuta a injini amatsika nthawi zonse chifukwa cha utsi?

Kutentha ndi kutentha kwa mafuta mu injini. Koma akhoza "kusiya" injini osati pa kuyaka, komanso zifukwa zina zambiri:

1. Mafuta amatha kutuluka pansi pa chivundikiro cha valve pamene adaphwanyidwa kwambiri kapena gasket yawonongeka. Kuti muwone vutoli sizovuta, muyenera kuyang'ana pansi pa hood.
2. Kusindikiza kwamafuta a crankshaft kumathanso kukhala chifukwa cha kutayikira kwamafuta. Kuti muzindikire vutoli, mukhoza kuyang'ana malo omwe galimotoyo inali ndipo ngati pali chithaphwi cha mafuta, ndiye kuti n'zotheka kuti ichi ndi chisindikizo cha mafuta. Ili ndi vuto lodziwika bwino. Zitha kuchitika chifukwa cha mafuta oyipa kapena kuvala kwa chisindikizo chokha.
3. M'malo mwa fyuluta yamafuta, amatha kuyiwala kuyika chingamu chosindikizira, kapena osamangitsa fyulutayo yokha. Zitha kuyambitsanso kutayikira. Yang'anani momwe fyulutayo imapotozedwa, komanso mtundu wa rabala kuti usindikize.
4. Chifukwa china chosavuta chingakhale zisindikizo za valavu (zimakhalanso zisindikizo za valve). Amapangidwa kuchokera ku mphira wosamva kutentha, koma amakhalabe mphira, ndipo chifukwa cha kutentha kwambiri, zipewa zimayamba kuoneka ngati pulasitiki, zomwe sizimagwira ntchito yake ndipo mafuta amayamba "kuchoka".

Kodi kuwotcha mafuta kumadalira kokha

O zedi. Mafuta osankhidwa molakwika sangakwaniritse miyezo ya injini iyi ndipo akhoza kupsa mtima.

Ndi magawo ati amafuta omwe amakhudza zinyalala

Pali zinthu zambiri zomwe zimapangitsa kuchuluka kwa mafuta omwe amayaka mu injini:

• Evaporation molingana ndi njira ya Nowack. Njirayi ikuwonetsa chizolowezi cha mafuta opangira madzi kuti asungunuke kapena kuwotcha. Kutsika kwa chizindikirochi, (chosonyezedwa mu%), ndibwino (kuchepa kumazirala). Mafuta opangira mafuta apamwamba ayenera kukhala osachepera 14 peresenti pa chizindikiro ichi.
• Mtundu wa mafuta oyambira. Kuchokera m'ndime yapitayi, mutha kudziwa kuti "maziko" anali abwino bwanji panthawi yopanga. Kutsika kwa nambala ya Noack, "base" linali bwino.
• Viscosity. Kuchuluka kwa mamasukidwe amphamvu, kumachepetsa index ya Noack. Ichi ndichifukwa chake, kuti muchepetse zinyalala, mutha kusintha mafuta a viscous. Mwachitsanzo, mumadzaza mafuta a 10W-40 ndi kutentha kwambiri, mutha kusinthana ndi 15W-40 kapena 20W-40. Zatsimikiziridwa kuti kusiyana pakati pa zinyalala 10W-40 ndi 15W-40 ndi pafupifupi 3.5 mayunitsi. Ngakhale kusiyana kooneka ngati kakang'ono kungakhudze kumwa.
• HTHS. Imayimira "High Temperature High Shea", ngati itamasuliridwa, idzakhala "High Temperature - Big Shift". Mtengo wa chizindikiro ichi ndi udindo wa mamasukidwe akayendedwe a mafuta. Magalimoto atsopano amagwiritsa ntchito mafuta okhala ndi chizindikiro cha mtengowu osakwana 3,5 MPa * s. Ngati mafuta amtundu uwu amatsanuliridwa m'galimoto yachikulire, izi zidzapangitsa kuchepa kwa filimu yotetezera pazitsulo ndi kusinthasintha kwakukulu, chifukwa chake, kuwonjezeka kwa zinyalala.

Mafuta omwe amachepetsa kugwiritsidwa ntchito osati chifukwa cha zinyalala

Kuchuluka kwa mafuta oyaka moto kumatha kuchepetsedwa mothandizidwa ndi zowonjezera. Pali chiwerengero chachikulu cha iwo. "Iwo amasokoneza" mikanda mu silinda, motero amachepetsa zinyalala.

Momwe mungasankhire mafuta osatha

Kuti musamawerenge molakwika, mutha kugwiritsa ntchito njira ziwiri:

1. Onani ndemanga. Mutha kupita patsamba logulitsa mafuta odzola ndikuwona ndemanga pa chilichonse chomwe mungafune. Mutha kupitanso kumabwalo osiyanasiyana komwe amakambilana zamafuta a injini, pali ambiri aiwo.
2. Dziyeseni nokha. Njirayi ndi yoyenera kwa anthu omwe amakonda kuchita zoopsa kapena sakhulupirira ndemanga. Ngati muli ngati chonchi, ndiye kuti bizinesiyo imatha kukoka kwa nthawi yayitali, chifukwa muyenera kugula mafuta, kudzaza, kuyendetsa makilomita 8-10, ndikuyesanso khalidwe lake ndi makhalidwe ena.

Mafuta amatha kuyaka ngakhale pa injini yatsopano. Ngati mulingo watsika, muyenera kuyang'ana chisindikizo chamafuta a crankshaft, chivundikiro cha ma valve, zisindikizo za ma valve ndi nyumba zosefera mafuta kuti zitsike. Komanso, musanagule mafuta, muyenera kudziwa mafuta omwe ali oyenera injini yanu.

Kuti muchepetse kutopa, mutha kusintha mafuta owonjezera. Ndipo ngati mafuta "amasiya" malita 1-2 makilomita zikwi, ndiye kukonzanso kwakukulu kungathandize. Zabwino zonse panjira ndikuwona galimoto yanu!
