Uyini fuel kanye zokugcoba

Ngokusho kwemibiko ezingaqinisekisiwe, uthambise esetshenziswa indoda isikhathi esingaphezu 6 ayizinkulungwane. Eminyakeni eminingi edlule. Amafutha yaziwa isikhathi eside, kodwa ukuyisebenzisa injalo okumsulwa samuva nje, kodwa ukucutshungulwa yokukhuluma kanye ingahambi. Lapho Abantu bafunda ukuyicubungula, thina sabe sesithatha kaphalafini kuphela, njengoba eyigugu kakhulu - uwoyela - esetshenziswa njengoba okokubasa, noma umane zishiswe. Futhi ezingu-90% ngesisindo sezinti uwoyela eziyisisekelo.

Kodwa ubuchwepheshe akemi namanje - futhi manje zokuwuhluza baye bafunda ukuhlukanisa amafutha zihlukaniswe zibe izingxenyana ezihlukahlukene. ukuphathwa Okwalandela ayithelanga amafutha aphambili kuwo, ngaleso sikhathi eyayibizwa ngokuthi uwoyela noma amaminerali. Ngo izinjini yesimanje izimoto - okusezingeni eliphezulu mechanical ukushisa umthwalo, ngakho zokugcoba ngabo kumelwe ahlangabezane nezimfuneko ezithile.

Ukuze uthuthukise izinga lamafutha lubricating ngokusebenzisa kwalokho nalokho izinto ezikhethekile (izithasiselo). Ngayinye yalezi izithasiselo kuthuthukisa indices eyodwa noma ngamaphuzu ambalwa. Ngokwesibonelo, protivoiznosostoykie okufakiwe ukungezwa zokugcoba ukunciphisa izinga zokukhandleka izingxenye ukusebenza, futhi yokuhlanza - inciphise imali kanye nokuvikela piston indandatho ababambelela. amafutha lubricating Modern bangathembela engaphezu kweyishumi ukwanda.

With ezahlukene kwezithako kanye kungenzeka ukuhlanganisa kubo bese ukwandisa uhla, enganikeza abakhiqizi. Lokhu amafutha lubricating lapho ukukhiqiza. Futhi nje, kukhona futhi babehlale bekhona abambalwa target yabo zinhlobo - injini, ukudluliswa kanye nezinye. Ngaphambi kokuba uthenge lubricating amafutha (ngisho nomkhiqizi owaziwa) odinga ukukwazi izimiso eziyisisekelo abalithandayo.

Namawoyela babe imingcele eminingi elicacisiwe izici lobuchwepheshe, kodwa ukuthengwa kuyadingeka ukuze sinake kuphela bobabili. izinga uwoyela ezingeni likhombisa kwedivayisi emotweni yakho le nto, futhi viscosity - sokufaneleka yayo ukusetshenziswa ezindaweni ethile futhi inkathi.

Ukuze unqume ukuthi yileyo igrisi kuzosiza mshini samanje kunoma iyiphi ibanga kwezohwebo, efanayo global nangenkomba uhlelo. Ubuchwepheshe echazwe amazinga kwezilwandle nezincazelo ecacisiwe viscosity Inkomba ngokuvumelana nenqubo yamukelwa-American Society of Izithuthi Onjiniyela Sae, ngaleyo ndlela ukuyichaza ukuthi viscosity uzobe wabonisa ngemva kokuphawula Sae izincwadi. Okhonjiswe incwadi W amamaki ebusika izinto zokubasa kanye zokugcoba, futhi ehlobo - liyisibonelo okulula viscosity.

Kukhona notation ejwayelekile. Ngokwesibonelo, ngaphansi nesiqu Sae J300 ukufihla amaklasi eziyisithupha imodi viscosity ebusika - 0W, 5W, 10W, 15W, 20W, 25W. Zonke lezi zigaba aqinisekisiwe ukuqala umshini e isimo abandayo, futhi ukunyakaza uphethiloli kanye zokugcoba senzeka ngokukhululeka kulo uhlelo in ezahlukene lokushisa -30- + 5 degrees. Summer izinhlobo awunawo amanye amagama kule wokugubha, kodwa ukwanda viscosity lezi izinhlobo yizigaba ka Sae 20, 30, 40, 50, 60.

Manje ngoba sewuyazi ukuthi lokho fuel kanye zokugcoba, futhi yini ngezigaba zabo!
