Kungani amafutha angu-5W-30 kanye ne-5W-20 evame kangaka?

Ukushintsha uwoyela kungomunye wemisebenzi ebaluleke kakhulu yokunakekela imoto. Izimoto eziningi zisebenzisa amafutha angu-5W-20 noma angu-5W-30 ngoba la mafutha enza kahle kakhulu emazingeni okushisa aphezulu noma aphansi.

Mayelana nokunakekelwa kwemoto, akukho okubaluleke ngaphezu kokushintshwa kwamafutha. Isizathu esenza ukuthi 5W-30 futhi 5W-20 motor amafutha avame kangaka ngoba asebenza kahle kakhulu nge anhlobonhlobo izinjini. Ngokuvamile kunalokho, lezi zinhlobo zamafutha zifaneleka kakhulu ezinhlobonhlobo zamazinga okushisa angenzeka: 5W-20 ifaneleka kakhulu ezindaweni ezibandayo, futhi i-5W-30 ifaneleka kakhulu emazingeni okushisa aphezulu kakhulu. Ngokwengxenye enkulu, noma yikuphi kwalokhu kufanele kusebenze kahle enjinini kungakhathaliseki izinga lokushisa elikhona.

Umehluko phakathi kukawoyela wenjini engu-5W-30 no-5W-20

Umehluko omkhulu phakathi 5W-30 injini uwoyela kanye 5W-20 wukuthi yokugcina viscous kancane (noma mkhulu). Uma esetshenziswa enjinini yemoto, uwoyela we-5W-20 udala ukungqubuzana okuncane ngenxa ye-viscosity yawo ephansi, okusho ukuthi abangela ukudonsa okuncane ezingxenyeni zenjini ezifana ne-crankshaft, isitimela samavalvu, namapiston. Lokhu kungase kunikeze ukunyuka okuncane ekusebenzeni kahle kukaphethiloli.

Uketshezi oluthe xaxa lwamafutha angu-5W-20 luphinde luvumele iphampu kawoyela ukuthi iwususe kalula epanini likawoyela uwuyise kuyo yonke injini. Lokhu kwenza i-5W-20 ithandeke ezindaweni ezibandayo kakhulu lapho kubalulekile ukuba nowoyela ozacile ongageleza kalula uma uqala. Lapho i-5W-30 ingena khona kusesimweni sezulu esishisayo lapho uwoyela owuketshezi uvame ukuphuka emazingeni okushisa aphezulu. Lokhu kuhumusha amandla kawoyela angu-5W-30 ukuwavimbela ekubhidlikeni ngokushesha njengowoyela ongu-5W-20, okuhlinzeka ngokuvikeleka okungcono kakhulu kwezingxenye zenjini.

Amafutha ane-viscosity efanayo namafutha ane-viscosity ehlukene

Aklanyelwe ukusebenza ezibangeni ezihlukene zokushisa, la mafutha ane-viscosity eningi angenye yamafutha enjini yezimoto angcono kakhulu. Amafutha e-viscosity esikhathi esidlule ayenikeza isivikelo esimweni sezulu esishisayo nesibandayo, kuye ngokwengxenye enkulu ngesisindo noma amazinga okushisa abandayo kakhulu ayesebenza kuwo. Lokhu ngokuvamile kwakusho ukusebenzisa amafutha angu-5W-30 ekwindla nasebusika kanye no-10W-30 entwasahlobo nasehlobo.

Ngakolunye uhlangothi, amafutha e-multi-viscosity asebenzisa izithasiselo ezikhethekile ukwandisa i-viscosity yamafutha. Okuxakayo ukuthi lezi zithuthukisi ze-viscosity ziyakhula njengoba uwoyela ushisa, unikeza i-viscosity ephakeme emazingeni okushisa aphezulu. Njengoba uwoyela uphola, lezi zithako ziyacindezela, zenze uwoyela ube mncane, okuyinto efanelekela ukusetshenziswa emazingeni okushisa enjini aphansi.

Indlela izithasiselo zikawoyela ezisiza ngayo ukuhlanza nokuvikela injini yakho

Abakhiqizi bakawoyela basebenzisa izithasiselo zikawoyela wezimoto ukuze bathuthukise ukusebenza kukawoyela uma kukhulunywa ngokugcoba. Ngaphezu kwalokho, eminye imiphumela yezithasiselo emafutheni ihlanganisa ukuhlanza izingxenye zenjini kumadiphozithi, ukuvimbela ukugqwala noma ukugqwala ngaphakathi kwenjini, nokuvimbela ukuwohloka kukawoyela ngenxa ye-oxidation noma izinga lokushisa elidlulele.

Yimaphi amafutha okufanele abanikazi bezimoto bawasebenzise?

Uma ufuna amafutha enjini alungele imoto yakho, kunezici ezithile okufanele uzikhumbule. Nakuba ungekho umehluko omningi phakathi kokuvikelwa okunikezwa uwoyela we-5W-30 kanye no-5W-20, kunomehluko omncane kumazinga e-viscosity ngayinye. I-5W-30 ewugqinsi kufanele ibe nenzuzo encane ekusebenzeni okuphakeme kwezinga lokushisa, kuyilapho ezacile i-5W-20 kufanele inikeze ukuvikelwa kwenjini okungcono emazingeni okushisa aphansi futhi ibe nenzuzo eyengeziwe yokwenyuka kancane kokusebenza kahle kukaphethiloli.

Ukuguquguquka kwamafutha esimanje enziwe ngezimoto kusho ukuthi uwoyela we-5W-30 kanye no-5W-20 uvikela injini yakho ngokulinganayo kungakhathaliseki isimo sezulu noma isizini. I-Mobil 1 inikezela ngezinhlobonhlobo zamafutha ane-viscosity amaningi ukuze afanele injini yakho. I-AvtoTachki inikeza uwoyela wekhwalithi ephezulu wokwenziwa noma ojwayelekile we-Mobil 1 ngazo zonke izinguquko zikawoyela weselula.
