5W20 uwoyela motor: Ukucaciswa, izici kanye nokubuyekeza

Injini - inhliziyo imoto. Kusukela umsebenzi wakhe incike ekusebenzeni efanele zonke ezinye amayunithi netindlela. Ngakho-ke, ngezinga elithile lapho wenza yesondlo idinga ukunakekelwa okukhethekile. Nekusebenta motor incike uhlobo Lubrication. Namuhla, abashayeli uthanda motor uwoyela 5W20. Ngezinye izikhathi abanye abantu musa ngisho sinake nehhanisi sika. Sizokwenza baqonde isizathu ukuthandwa lonke kwalo mkhiqizo.

okulotshiweyo

Lapho ekhetha uwoyela motor kubalulekile ukuba banake izilinganiso ezimbili - isigaba izinga kanye degree of viscosity. Umngcele we-lokuqala kunqunywa inhlanganisela yezinhlamvu izinhlamvu zesiLatini kanye uphawu S uphethiloli izinjini, futhi uphawu C - Udizili yokumba. Ngokwesibonelo, i-CC noma SJ. Gxila izinga esigabeni ngeke. Phawula kuphela ukuthi phambidlana kutsi lena yincwadzi yesibili zamagama kusukela ekuqaleni, amafutha engine zanamuhla. Ngakho, ngo-SJ waqalisa nobuchwepheshe obuphambili bezokuphepha edlula SH. Class viscosity uketshezi ezikhonjiswe wokugubha uhlobo 5W20. It kunquma ukuthi uketshezi kakhulu viscous isezingeni okufanayo noma lokushisa ezahlukene kuma. Ngaphakathi accordance nga lo brand ebusika secrete amafutha, ungakwazi azomakwa iwuphawu W, ehlobo - banikwa izinombolo kuphela, futhi jikelele - inhlanganisela ebusika kanye nasehlobo chungechunge. Ngakho, 5W20 uwoyela multigrade kuyinto.

Amafutha viscosity futhi lokushisa

Engine uwoyela viscosity oluthinta ngqo ukuthi ukuhlala phakade injini. Uma lesi sibalo sincane kakhulu, amafutha azogeleza esukela yezingxenye ngomshikisho injini, ngaphandle kokunikeza isivikelo. Ngakolunye uhlangothi, uma viscosity okusezingeni eliphezulu ketshezi akanayo isikhathi ukungena phakathi evele eziveza phakathi ekuqaleni-up, kakhulu ukunciphisa injini ukuphila. I viscosity noma yiluphi uketshezi incike lokushisa kuma. I esibandayo ke ingaphandle, lo mkhulu amafutha iba, kanye kancane it embula ezingxenyeni friction, kodwa okuhamba phambili kwe-amajazi abo, ifilimu zokuzivikela ihlala isikhathi eside. Kodwa uma ngaphansi kwamazinga okushisa aphansi zisebenzisa amafutha nge viscosity ephakeme, ke nje eba yiqhwa futhi ngokuvamile akufakiwe emsebenzini.

5W20 uwoyela has ukungaguquguquki oluzovumela okusheshayo e ukusebenza ngesikhathi injini isiqalo ebusika, kodwa ngesikhathi esifanayo akubi uketshezi kakhulu okushisa ambient angaphezu kwezinga-qhwa. Lilele esinye sezici we Lubrication kulesi sigaba.

viscosity kinematical

Ukumanzisa ngoba inkathi ehlobo kufanele kube viscosity ephakeme, okuyilona elidingekayo ukuze umuntu ukusebenza injini elikhulu etinhlotjeni letehlukene okushisa ezisebenza. uwoyela Winter ngokuphambene has a viscosity ongaphakeme, okuyinto kusiza starting yenjini. Nokho, iyazifudumeza, umkhiqizo ilahlekelwa izinga layo. I igrisi wonke-sezulu, njengoba esimweni sethu uwoyela 5W20, kumelwe kanyekanye ukuhlangabezana nalezi izimo ezimbili. viscosity Kinematic, okuyinto ejwayelekile esengeziwe uphethiloli ehlobo, kunqunywa ezingeni lokushisa 100 ^° C, lesi sibalo ebangeni elithile ukuze ukudla isizini.

Ukunciphisa umbandela kinematic ngezansi embundwini okuholela bafake olunzulu we crankshaft futhi camshaft izingxenye indlela crank. Ukwandisa imiphumela efanayo "ebulawa indlala" powerplant scuffing futhi bafake kwesikhathi.

viscosity ashukumisayo

Zonke-sezulu okugcotshwayo njengoba uma bethu 5W20 uwoyela, kumelwe futhi abe nezici komkhiqizo ebusika. It libhekene a viscosity ashukumisayo, okuyinto yena, kunqunywa zindlela ezimbili:

• ukuqondisa - esiphezulu ukuminyana avumelekile Lubrication lapho crankshaft iqala ujikelezisa ezidingekile amakhaza isiqalo isivinini;
• pumpability - viscosity esiphezulu amafutha, iqinisekisa ukuthi futha uwoyela ngeke ukumpompa emoyeni esikhundleni amafutha.

ashukumisayo viscosity isheke uqhutshwa othini ekhethekile ezingeni lokushisa ethile emoyeni. Walesigaba uwoyela viscosity 5W ke ilingana -35 ^° C

Izimpawu uwoyela engine 5W20

Ukunqunywa uwoyela engine Ukucaciswa eyenziwa ngaso izimo eduze ngokoqobo. Izinkomba ichazwe izitshalo umshayeli ekhethekile, ezifana viscometer mini-rotary noma Simulator ukuqalisa.

Kakhulu ngokuvamile abakhiqizi ukuhlola umkhiqizo wabo ku viscosity ashukumisayo. Ngakho ukwenza izinkampani "Ford", "Mercedes", "Hyundai". uwoyela yabo 5W20 ayishintshi viscosity yayo izici ngisho at eliphezulu kakhulu okushisa yokusebenza, okuyinto zivikela injini bafake ngesikhathi ukuminyana okukhulu.

Amafutha 5W20 futhi 5W40

Ngenxa zibiza nekwenteka ongaphakeme, abashayeli abaningi bakhetha ugcwalise imoto yakho Esikhundleni samafutha 5W20 5W40 brand. Ukuthi lolusuku lesi senzo kungenziwa ngemibuzo. abakhiqizi abaningi yesimanje ukutusa ukusetshenziswa ongaphakeme-viscosity motor amafutha ngenxa eziphambili injini design. Ikakhulukazi, izitshalo eziningi amandla encishisiwe nokusulwa e ngomshikisho ngazimbili, kukhona uhlelo olukhethekile has isikhathi salo siqu kanye nezinye izici. Ukuze injini operation lesifanele, ukushisa ukususwa kokudingekile bushings ngamafutha viscosity ongaphakeme, njengalapho 5W20.

Ngokwe-nokubuyekezwa, 5W20 futhi 5W40 amafutha ukunikeza Nokho, iyunifomu kanye injini operation esitebeleni, lapho usebenzisa samuntu kuqala ukuvela zokugwema ukuphuka kakhulu kancane futhi ukungasebenzi sokuphehla amandla cishe ningagcini. Ngakolunye uhlangothi, ukusetshenziswa 5W40 grade ngeke ebulalayo enjinini.

Izici uwoyela 5W20 kusukela Castrol

Kuze kube manje, nomakhi baqaphela amafutha engine iyona Castrol inkampani. Ikakhulukazi "Castrol" uwoyela 5W20 ngoba "Ford" kanye nezinye brand imoto kwakubangelwa yawo yamakhemikhali ifomula. Njengengxenye ye-igrisi waxes bengekho ngokuphelele, ngakho umkhiqizo ayigongobali ngisho okushisa aphansi kakhulu. Amafutha has a high oxidative izinqubo ukumelana ukusebenza ngenxa yokuba khona kwama-atom sulphur, phosphorus kanye chlorine lichaza ekwakheni izithasiselo. Ngu uqobo, igrisi akuyona inhlanganisela ngezinto ezahlukene, futhi umkhiqizo eyohlobo. Amafutha uncoma ukusebenzisa izincomo yomenzi, kuyilapho nawe ungalushayi ukuxubana ukuthi nezinye brand.
