Okushiwo izifinyezo emafutheni enjini

03.06.2022 /

Wonke amafutha anezinombolo nezifinyezo, ngokuvamile esingazi ukuthi asho ukuthini, futhi singasebenzisa okungafanelekile emotweni.

Amafutha enjini angolunye loketshezi olubaluleke kakhulu ekusebenzeni nempilo ende yemoto. Ukugcinwa ngesikhathi kanye nokuqwashisa ngowoyela kuzogcina injini yakho isebenza futhi ingenawo umonakalo ngenxa yokuntuleka kukawoyela.

Kunezinhlobo ezahlukene zamafutha, ungathola amafutha emakethe. ama-synthetics noma amaminerali, ngokuya ngesicelo sabo, kodwa kusukela lapho bonke banezinombolo nezifinyezo ngokuvamile esingazi ukuthi zisho ukuthini futhi singasebenzisa eyodwa engahambisani nemoto.

Abaningi bethu basebenzisa uwoyela we-multigrade ngoba bahlangabezana nezindinganiso ze-SAE kuzo zombili izimo. Zinezici zamafutha alula ukuze zisebenze kahle emazingeni okushisa aphansi kakhulu kanye nezici zamafutha anzima ukugcina i-viscosity emazingeni okushisa aphezulu. Lokhu kufezwa ngokungeza izithasiselo kuwoyela ezibangela ukuthi i-viscosity ikhuphuke njengoba izinga lokushisa lenjini likhuphuka, nokugcina ukugcotshwa kwenjini njalo nokuvikela,

Yingakho lapha sizokusiza ukwazi incazelo yalezi zifinyezo.

  • Incazelo yokuqala SAE, Inhlangano Yezobunjiniyela Bezimoto, banesibopho sokwenza amakhodi amafutha enjini kuye ngokuthi i-viscosity yabo namandla enjini. amafutha okugcoba yenza umsebenzi wayo kuye ngokuthi izinga lokushisa injini izoqala ngalo.
  • La sigla "W", Lesi sifinyezo singesamafutha afanele izinga lokushisa eliphezulu. Ngamanye amazwi, elithi "w" libonisa ebusika noma ubusika futhi yinani le-viscosity emazingeni okushisa aphansi.
  • Inombolo ngemva kwesifinyezo. Isibonelo: SAE 30 ngo 10n 50 Inombolo ngemva kwesifinyezo ibonisa uhlobo lwamafutha ekushiseni okuphezulu. Lokhu kusho ukuthi, ngokusekelwe kwisifinyezo 5W-40, la mafutha azoba izinga lokushisa eliphansi le-5 kanye nokushisa okuphezulu kwama-40, okusho ukuthi inezici ze-viscosity ephansi futhi injini ingaqalwa emazingeni okushisa aphansi kakhulu.

    • Ungathola futhi izifinyezo ezifana ne-API SG, ehlukanisa ikhwalithi kawoyela yezinjini ezine-stroke, noma i-"API TC", ehlukanisa ikhwalithi yezinjini ezinemivimbo emibili, nezifinyezo. I-ISO-L-EGB/EGC/EGD iyincazelo yamazwe ngamazwe kawoyela wenjini enemivimbo emibili.
