Chifukwa chiyani mafuta a injini amanunkhira ngati mafuta? Kuyang'ana zifukwa

zifukwa

Ngati mafuta a injini amanunkhira ngati mafuta, ndiye kuti injiniyo imasokonekera, chifukwa chomwe mafuta amalowa m'galimoto yamafuta. Payokha, mafuta, mosakayikira, adzatulutsa fungo la mafuta.

Pakhoza kukhala zifukwa zingapo za maonekedwe a fungo la mafuta mu mafuta.

1. Kuphwanya dongosolo lamagetsi lamagetsi. Kwa injini za carbureted, kusintha kosayenera kwa singano ndi carburetor kutsamwitsa kungayambitse mafuta ochulukirapo ku injini. Kulephera kugwira ntchito kwa nozzles kudzachititsanso "kusefukira". Mu silinda panthawi yogwira ntchito, mafuta ochepa okha amatha kuwotcha (gawo lofanana ndi chiŵerengero cha stoichiometric). Gawo lomwe silinatenthedwe lamafuta limawulukira pang'ono mu utsi wambiri, pang'ono limadutsa mu mphete za pistoni kulowa mu crankcase. Kuyendetsa kwanthawi yayitali ndikuwonongeka kotereku kumabweretsa kudzikundikira kwa petulo mu masilindala komanso mawonekedwe a fungo lapadera.
2. Zolakwika. Mapulagi osokonekera olakwika, kulephera kwa njira yoyatsira nthawi, mawaya osweka kwambiri, kuvala kwa wogawa - zonsezi zimabweretsa kuwonongeka kwamafuta nthawi ndi nthawi. Mafuta osawotchedwa mu sitiroko yogwira ntchito amalowa pang'ono mu crankcase.

3. Valani gulu la silinda-pistoni. Panthawi yoponderezedwa, ngati ma cylinders ndi mphete za pistoni atavala moyipa, kusakaniza kwamafuta a mpweya kumalowa mu crankcase. Mafuta amafuta amakhazikika pamakoma a crankcase ndikulowa mumafuta. Kuwonongeka kumeneku kumadziwika ndi kuponderezana kochepa mu masilinda. Komabe, ndi kuwonongeka kumeneku, njira yolemeretsa mafuta ndi petulo imayenda pang'onopang'ono. Ndipo mafuta amakhala ndi nthawi yoti asungunuke ndikutuluka kudzera mu mpweya. Pokhapokha ngati atavala movutikira ndiye kuti mafuta ochulukirapo amatha kulowa mumafuta kuti amve kununkhira kwa mafuta pa dipstick kapena kuchokera pansi pa khosi lodzaza mafuta.

Samalani mlingo wa mafuta pa dipstick. Vutoli limakhala lalikulu ngati, kuwonjezera pa fungo, kuwonjezeka kwa mafuta kumawonedwa. Pankhaniyi, m'pofunika kuthetsa chifukwa cha kulephera mwamsanga.

Zotsatira

Ganizirani zotsatira zomwe zingakhalepo mutayendetsa galimoto ndi mafuta odzaza ndi petulo.

1. Kuchepetsa magwiridwe antchito amafuta a injini. Mafuta aliwonse a injini zoyatsira mkati, mosasamala kanthu za kuchuluka kwake, amagwira ntchito zambiri. Mafuta akasungunuka ndi petulo, zina mwazinthu zofunika zamafuta a injini zimatsika kwambiri. Choyamba, kukhuthala kwa mafuta kumachepa. Izi zikutanthauza kuti pa kutentha kwa ntchito, chitetezo cha malo ophwanyika odzaza chimachepetsedwa. Zomwe zimatsogolera kumavalidwe othamanga. Komanso, mafutawo amatsukidwa mwachangu kuchokera pamikangano ndipo, nthawi zambiri, kumakhala koyipa kwambiri kukhala pamalo ogwirira ntchito, zomwe zingayambitse kuchulukitsitsa kwazinthu zolumikizana poyambitsa injini.
2. Kuchulukitsa kwamafuta. Nthawi zina, kumwa kumawonjezeka ndi 300-500 ml pa 100 kilomita.
3. Kuwonjezeka kwa chiopsezo cha moto mu chipinda cha injini. Pali nthawi pamene nthunzi ya petulo imayaka mu crankcase ya injini. Panthawi imodzimodziyo, choyikapo mafuta nthawi zambiri chinkawombera kuchokera pachitsime kapena gasket ankafinya kuchokera pansi pa chivundikiro cha valve. Nthawi zina kuwonongeka pambuyo pa kung'anima kwa petulo mu crankcase kunali koopsa: gasket yowombedwa pansi pa poto kapena mutu wa silinda, pulagi yamafuta idang'ambika ndikuyaka moto.

Pali njira zingapo zodziwira kuchuluka kwamafuta mu petulo. M’lingaliro limenelo, kaya vutolo ndi lalikulu.

Choyamba komanso chophweka ndikusanthula kuchuluka kwa mafuta mu crankcase. Mwachitsanzo, ngati injini ya galimoto yanu yadya kale mafuta, ndipo mumagwiritsa ntchito nthawi ndi nthawi kuwonjezera mafuta pakati pa zosintha, ndiyeno mwadzidzidzi mumapeza kuti mlingowo ukuima kapena kukula, ichi ndi chifukwa chosiya kugwiritsa ntchito galimoto. ndikuyamba kuyang'ana chomwe chimapangitsa kuti mafuta alowe mu makina opangira mafuta. Mawonetseredwe a vutoli akuwonetsa kulowetsedwa kochuluka kwa mafuta mumafuta.

Njira yachiwiri ndikuyesa kutsitsa kwamafuta a injini pamapepala. Ngati dontho limafalikira nthawi yomweyo ngati njira yamafuta opaka papepala pamtunda waukulu, nthawi 2-3 pamalo omwe amakutidwa ndi dontho, mafuta amakhala mumafuta.

Njira yachitatu ndiyo kubweretsa lawi lotseguka ku choyikapo mafuta. Ngati dipstick imawalira ndi kuwala kwachidule, kapena, choipitsitsa, chikuyamba kuyaka ngakhale ndi nthawi yochepa yokhudzana ndi moto, kuchuluka kwa mafuta mu mafuta kupitirira malire oopsa. Kuyendetsa galimoto ndi koopsa.
