5W30: mawu olembedwa mafuta kabisidwe injini

Onse galimoto mafuta galimoto anawagawa m'magulu atatu: petulo, dizilo ndi chilengedwe. Komabe, iwo zidzasankhidwa pa nyengo yozizira ndi yotentha. Koma zomwe kalasi iwo ali, khalidwe ndicho chimodzi cha mafuta - kukhuthala. Ndi pa chizindikiro ichi zimadalira yogawa mlingo wa madzi pamwamba pa mbali injini kukhululukirana. Tikhoza kunena kuti pa kukhuthala zimatengera zambiri gwero galimoto kuyaka mkati injini, kotero lero tinapereka mphindi ino nkhani osiyana. Today mudzaphunzira mphamvu zimene, ndi bwino liwu monga decryption injini mafuta 5w30.

kukhuthala ndi chiyani?

Ntchito yaikulu ya madzimadzi - kuteteza mikangano kusamukira mbali mkati galimoto ndi "wouma." Komanso, mafuta zipangitsa kochepa mikangano, pokhalabe pazipita zikayamba kugwira ntchito zonenepa.

Tikumbukenso kuti makhalidwe ndi katundu wa madzi lubricating zingasiyane kwambiri malinga kutentha kwa injini. Zodabwitsa ndizakuti, deta galimoto kutentha zomwe amalembedwa chida galimoto lonse, zingasiyane kwambiri ndi mlingo mafuta kutentha. Ndipo si anasonyeza chida gulu m'chipinda anthu. Malinga ndi mphamvu ya injini kuyaka mkati, mankhwala amatha mkangano digiri 140-150 Celsius (ndipo zimenezi ngakhale kuti pa opaleshoni kutentha kwa injini ndi wofanana ndi madigiri 90!). Koma pansi pa zikhalidwe izi, madzimadzi kukhuthala zingasiyane kwambiri kuchokera pachiyambi.

N'chifukwa chake, kuonetsetsa yaitali zotheka moyo opaleshoni ndipo mikangano kochepa pa makoma yamphamvu, aliyense galimoto kumafuna mtundu wina wa mafuta analimbikitsa ndi kampani yopanga magalimoto.

Sam kukhuthala chizindikiro china chofunika kwambiri ndi makina, chifukwa limakhudza mphamvu kukhalabe madzi padziko zigawo injini kwa nthawi yaitali. Koma njirayi, monga taonera kale, akhoza zimasiyana kwambiri pa kutentha osiyana. Koma bwanji kumvetsa zimene kukhuthala mafuta ayenera Choncho? Mwamwayi, njira yothetsera vutoli (SAE) anapezeka mu Association American wa Automotive Akatswiri, omwe anayamba gulu la galimoto mafuta kukhuthala. M'mawu ena, dongosolo limeneli limatipatsa osiyanasiyana kutentha pa zimene Ice ntchito ndi otetezeka, malinga "lubricant" wopanga kupanga magawo ngati ntchito injini izi.

Decoding mafuta olemba

5W30, 14W 40 - zizindikiro amenewa akupezeka pa wina chizindikiro kwathunthu ndi madzimadzi lubricating. Kodi chiyani?

Ndipotu aliyense kulemba mankhwala akuphatikizapo manambala angapo ankasiyana kalata W ndi dashes. Pankhaniyi, decoding injini mafuta 5w30 limasonyeza kuti madzimadzi izi zonse nyengo - wotchuka kwambiri pakati ziziyenda. Kudziwa makhalidwe onse mwatsatanetsatane lophweka. Tiyeni tione chitsanzo cha mafuta 5w30.

Chinawathandiza kumvetsa n'chakuti 5W limatiuza za otsika kutentha kukhuthala njira kuti akulola ozizira kuyamba galimoto pa kutentha 35 opanda madigiri Celsius. Izi anatsimikiza motere - kanjedza ku moyang'anana W mtengo, kuchotsera 40. Chiwerengero chifukwa ndi osachepera kutentha mafuta pa zimene Ice mpope umatha kupopa izo kupyolera dongosolo, kupewa mikangano mbali youma mkati.

Osachepera injini chiyambi mlingo

Chotero mwai masamu n'zotheka kudziwa osachepera kutentha "yoloŵetsapo" injini. Mu Chitsanzo 5w30 Mafuta decoding ife limasonyeza kuti chizindikiro ndi opanda madigiri 30 Celsius. Ndipo n'zosavuta wotsimikiza pa mtengo analandira ozizira chiyambi injini kutentha (Pankhaniyi ⁰ -35) kuchotsera 35. n'zoonekeratu kuti mafuta yozizira ndi ayamba wandiweyani, ndi sitata galimoto kuti tiyipukuse kovuta "kuzizira."

Choncho tinaganiza kodi mafuta 5w30 mawu olembedwa. Synthetics kapena "mchere madzi" - kudzadalira yekha pa zaka galimoto. Ngati makina ndi wamkulu kuposa zaka 5, pakuti ndi bwino kugwiritsa ntchito "madzi mchere", ngati wamng'ono, "synthetics".

Chonde dziwani

Tikumbukenso kuti onse a magawo kumatanthauza pamwamba ali ndi zaka yokha ya galimoto. Decoding (5w30 mafuta kuphatikizapo) amapereka deta idzatha. mfundo zenizeni zimadalira maonekedwe a injini, kotero muyenera osati kutseka maso athu ayamikira Mlengi wa posankha mafuta.

makhalidwe matenthedwe

Ambiri masiku ano galimoto mafuta opanga kulola ntchito zawo pa kutentha osati kuposa opanda 20 madigiri Celsius. Ngati mukukhala ngati nyengo kwa inu zilibe kanthu kusankha pakati mafuta 15W-40 ndi 5W-30. Chinawathandiza kumvetsa n'chakuti onse amalola ntchito ngakhale mu zankhanza kwambiri zimaperekedwa yozizira. Komabe, ngati sitata wanu / batire akale kwambiri / kanthu, ndi bwino kupereka mmalo mafuta 5W 30 kapena 0W-30. M'munsi kukhuthala, wamkulu mwayi kuti sitata wanu provernetsya injini ndipo ndinathamangira "mu ozizira".

Mkulu kutentha kukhuthala

chizindikiro china chofunika akusonyeza kalata W. Chiwerengerochi zikutanthauza apamwamba kukhuthala mafuta. Ifeyo ndi 5w30 madzi chizindikiro ichi ndi 30. Khalidwe limeneli limasonyeza kukhuthala osachepera ndi pazipita pa kutentha opaleshoni madigiri 100-150 Celsius. Mosiyana milandu yapita, palibe kanthu kalikonse. Onani kuti, apamwamba phindu, ndi apamwamba a mafuta kukhuthala pa kutentha. Koma posankha Sikuti kutsatira mfundo za "more bwino." Kachiwiri, magawo mulingo woyenera amasankhidwa ndi automaker, kotero kukhuthala index sayenera kwambiri kupatuka pa malamulo muyezo. Phunzirani malangizo onse angathe kukhala mu Buku opaleshoni.

Nthawi zina, galimoto kumafuna kukhuthala mkulu?

ziziyenda ambiri amakhulupirira apamwamba phindu bwino injini adzadzikuza. Chifukwa china choona. Chifukwa mwina? Chifukwa mafuta ndi kukhuthala mkulu amalangiza chophimba chokha mu magalimoto masewera. Koma izo mwamtheradi sizikutanthauza kuti ngati madzi thunthu mu Sandama, mu mawu a mphamvu ya kufalitsa, iye zinthu monga "Lamborghini". Komanso, kukhala mkulu-kukhuthala mafuta (amene ali osavomerezeka ndi Mlengi), ungachite kukulitsa injini ndi kuonjezera katundu. Chifukwa, galimoto wotaya mphamvu yake, ndipo ngati madzi kudzaza kachiwiri, n'zotheka kuti posachedwapa galimoto yanu yokha gonjerani likulu kukonza.

kangati Ndiyenera kusintha mafuta?

Pomaliza, tikuona mulingo woyenera kuda imeneyi. Amakhulupirira kuti mafuta limayenda a moyo wanu makilomita 10 chikwi. Ndi ndi imeneyi ino ndi bwino kusintha madzimadzi m'galimoto. More mwayi eni magalimoto ndi HBO: zikomo kwa mafuta kuyaka kwambiri zachilengedwe wochezeka (kaya ndi propane kapena dziko) mafuta pafupifupi sanali clogging ndi akuzisunga losavuta kumva ngakhale pa 20 zikwi mtunda. Muyeneranso kumaona mlingo wa zotsalira mu injini. Izi zichitike zosachepera kamodzi pa masabata 2. Mukatero sindikudziwa ngati yatsala konse mu galimoto, ndi kuyamba "youma" zingachititse mavuto aakulu, ku kukonzanso a. Choncho kusamalira galimoto lanu ndi kudzawatenga mafuta bwino kuti kutsatira malangizo a Mlengi.

Kotero, ife tinapeza chimene SAE 5w30 decoding, ndi kuphunzira zina zabwino zonse kukhuthala, komanso ngati mulingo woyenera kuda imeneyi ya madzi.
