Ndingashandisa 5w40 mafuta pachinzvimbo che5w30?
Zviri mukati
Imwe yemibvunzo inonyanya kufarirwa pakati pevatyairi ndeyekuchinjana kwemafuta emota. Mumaforamu akawanda, unogona kuwana mibvunzo yakajairika senge: "zvinoita here kuzadza mafuta e5w40 panzvimbo ye5w30?", "Zvinoita here kusanganisa mvura yemaminerari neyakagadzirwa kana semi-synthetics?" zvichingoenda zvakadaro. Isu takatopindura yakawanda yemibvunzo iyi pawebhusaiti yedu Vodi.su, uye isu takaongororawo zvakadzama maficha eSAE yekumaka yemafuta emota. Muchikamu chino, tichaedza kuona kana kushandiswa kwe5w40 panzvimbo ye5w30 kunobvumirwa.
Engine mafuta 5w40 uye 5w30: kusiyana uye unhu
Manyorerwo ezita rekuti YwX, apo “y” na“x” dziri dzimwe nhamba, anofanira kuratidzwa pamagaba einjini kana emafuta ekutakurisa. Iyi ndiyo SAE (Society of Automobile Engineers) viscosity index. Mabhii arimo ane zvirevo zvinotevera:
- vara rechiLatini W ipfupiso yeChirungu Chando - nguva yechando, ndiko kuti, mafuta uye mafuta ekuzora, kwatinoona tsamba iyi, inogona kushandiswa pazasi-zero tembiricha;
- nhamba yekutanga - muzviitiko zvose zviri "5" - inoratidza hushoma hwekushisa apo mafuta anopa crankshaft cranking uye inogona kuputirwa kuburikidza nehututi hwehuni pasina kuwedzera kupisa, nokuda kwe5W0 mafuta uye mafuta aya nhamba inotangira -35 ° C ( kupomba) uye -25 °C (kutendeuka);
- manhamba ekupedzisira (40 uye 30) - inoratidza hushoma hwetembiricha uye yakanyanya fluidity kuchengetedza.
Nokudaro, sezvo zvisina kuoma kufungidzira, maererano neSAE classification, mafuta ejini ari pedyo nemumwe uye kusiyana pakati pavo kuduku. Isu tinonyora kuti tijekese nenzira yerondedzero:
- 5w30 - inochengetedza viscosity pane ambient tembiricha mumhando kubva minus 25 kusvika plus 25 madhigirii;
- 5w40 - yakagadzirirwa hupamhi hwakawanda kubva paminus 25 kusvika pamwe ne35-40 madhigirii.
Ziva kuti tembiricha yepamusoro haina kukosha seyakadzika, sezvo tembiricha yekushandisa yemafuta muinjini inokwira kusvika 150 degrees uye pamusoro. Izvi zvinoreva, kana iwe uine Mannol, Castrol kana Mobil 5w30 mafuta akazadzwa mukati, izvi hazvirevi kuti panguva yerwendo kuenda kuSochi, uko kutonhora kunokwira pamusoro pe30-40 degrees muzhizha, inofanira kuchinjwa pakarepo. Kana iwe uchigara uchigara munzvimbo inopisa, saka iwe unofanirwa kusarudza mafuta uye mafuta ekuzora ane yakakwirira yechipiri nhamba.
Uye mumwe mutsauko wakakosha pakati peaya marudzi maviri ekuzora ndiwo musiyano we viscosity. Kuumbwa kwe5w40 kunowedzera viscous. Saizvozvo, kutanga mota pane tembiricha yakaderera zviri nyore kana mafuta mashoma e-viscous akazadzwa - mune iyi kesi, 5w30.
Saka zvinokwanisika here kudurura 5w30 pane 5w40?
Sezvimwe nemumwe mubvunzo pamusoro pekushanda kwemotokari, kune mhinduro dzakawanda uye kunyange dzakawanda "buts". Semuenzaniso, kana pane mamiriro ezvinhu akaoma, kusanganisa marudzi akasiyana-siyana emafuta uye mafuta anogamuchirwa, asi mushure mezvo iwe unogona kutsvaira injini zvachose. Saka, kuti upe kurudziro yehunyanzvi, zvinodikanwa kuongorora mamiriro ehunyanzvi hwemotokari, mirairo yemugadziri, uye mamiriro ekushanda.
Isu tinonyora mamiriro ezvinhu umo kuchinja kuoiri ine yakakwira viscosity index hazvigoneke chete, asi dzimwe nguva zvinongodiwa:
- panguva yekushanda kwenguva refu kwemotokari munzvimbo dzine mamiriro ekunze anopisa;
- nekumhanya pane odometer yemakiromita anopfuura 100 zviuru;
- nekudonha kwekumanikidza mujini;
- mushure mekugadzirisa injini;
- semushonga wekushandisa kwenguva pfupi
Zvechokwadi, mushure mokupfuura makiromita 100 zviuru, mapeji pakati pepistoni nemadziro evhavha anowedzera. Nekuda kweizvi, kune kuwanda kwemafuta uye mafuta, kudonha kwesimba nekumanikidza. Zvimwe zvinopisa zvinopisa nemafuta zvinogadzira firimu rekuwedzera kukora pamadziro kuti kuderedze mapundu. Saizvozvo, nekuchinja kubva pa5w30 kuenda ku5w40, iwe nekudaro unovandudza mashandiro esimba uye kuwedzera hupenyu hwesimba remagetsi. Ziva kuti mune yakawedzera viscous mafuta svikiro, kuedza kwakawanda kunoshandiswa kukorokoza crankshaft, saka mwero wekushandisa mafuta haugone kudzikira zvakanyanya.
Mamiriro ezvinhu umo shanduko kubva pa5w30 kuenda ku5w40 isingade zvakanyanya:
- mumirayiridzo, mugadziri akarambidza kushandiswa kwemamwe marudzi emafuta nemafuta;
- motokari itsva munguva pfupi yapfuura kubva ku salon pasi pewaranti;
- kuderera kwekushisa kwemhepo.
Uyewo ine ngozi zvikuru kune injini ndiyo mamiriro ekusanganisa mafuta ane fluidity yakasiyana. Mafuta haangogadziri nzvimbo chete, asiwo anobvisa kupisa kwakanyanya. Kana tikasanganisa zvigadzirwa zviviri zvakasiyana fluidity uye viscosity coefficients, injini ichapisa. Iyi nyaya inonyanya kukosha kumagetsi emazuva ano epamusoro-soro. Uye kana pachiteshi chebasa iwe ukapihwa kuzadza 5w30 panzvimbo ye5w40, uchikurudzira izvi nekushaikwa kwerudzi rwunodiwa rwemafuta mudura, haufanirwe kubvumirana, nekuti mushure mekuita kwakadaro kupisa kupisa kuchawedzera, izvo zviri yakazadzwa neboka rose rematambudziko anoenderana.
zvakawanikwa
Kubva pane zvese zvataurwa pamusoro apa, tinosvika pakugumisa kuti shanduko kune imwe kana imwe mhando yemafuta uye mafuta anogoneka chete mushure mekudzidza kwakadzama kwehunhu hwesimba remagetsi uye zvinodiwa nemugadziri. Zvinokurudzirwa kurega kusanganisa mafuta kubva kune vakasiyana vagadziri uye pazvigadziko zvakasiyana - synthetics, semi-synthetics. Kuchinja kwakadaro kune ngozi kune motokari itsva. Kana iyo mileage yakakura, zvinodikanwa kubvunza nyanzvi.
