Kungani izimoto zaseJapan zisebenzisa uwoyela we-viscosity ophansi?

【I-Master Bang 】 Kungani izimoto zaseJapan zisebenzisa uwoyela we-viscosity ophansi?

Kuwo wonke umlando wezimoto, ukukhuphuka kwemboni yezimoto yaseJapane kusekelwe ngokuqondile ezicini ezimbili zemikhiqizo yayo: engabizi futhi eyonga amandla. Ngala maphuzu amabili, izimoto zaseJapane kancane kancane ziye zafinyelela inani eliphakeme lokuthengisa kusukela ngawo-1980.

Ngakho-ke, abantu baseJapane bemoto, abathanda ukwenza izinto ngokwedlulele, banquma ukusebenzisa "uwonga uphethiloli" kuze kube sekupheleni, kuhlanganise nokuthuthukiswa kwe-viscosity ephansi, uwoyela osebenza kahle kakhulu. Namuhla, sizofika futhi simbe phansi ngokujulile, kungani izimoto zaseJapane zisebenzisa amafutha e-viscosity aphansi ~

Uyini umphumela wamafutha ekusetshenzisweni kukaphethiloli

Amafutha e-viscosity aphansi anciphisa ukumelana nokunyakaza kwenjini

Amafutha e-viscosity aphansi anganciphisa ukumelana nokungqubuzana phakathi kwezingxenye, okungukuthi, ukumelana nokusebenza ngaphakathi kwenjini.

Isivinini esihlukile, umphumela wokonga uwoyela we-viscosity ophansi uhlukile

Abakhiqizi abaningi baye benza izivivinyo kuwoyela we-viscosity ephansi, futhi imiphumela yathola ukuthi ukuncishiswa kokumelana nokugijima kwangaphakathi kwenjini kungasindisa ngempela uphethiloli.

Kodwa-ke, izingxenye ezihlukene zenjini ngesivinini esihlukile, isidingo se-viscosity yamafutha asifani, ngenani elincane lezingxenye, uwoyela we-viscosity ophansi awungcono kakhulu, futhi ube nemiphumela ethile emibi.

Amafutha e-viscosity aphansi angawonga kakhulu uphethiloli ekusetshenzisweni kwansuku zonke

Imiphumela yokuhlola ibonisa ukuthi phakathi kwebanga lika-1000 kuya ku-3000 RPM, uwoyela we-viscosity ephansi unemiphumela emibi emincane kanye nenzuzo esobala kakhulu yokonga uphethiloli, futhi kulobu bubanzi, umphumela wokonga uphethiloli awubonakali kangako.

Yiziphi izici ze-viscosity ephansi yezimoto zaseJapane

Ubuchwepheshe be-VVT

Izinjini zaseJapane bezilokhu zaziwa ngokuthembeka kwazo nokonga uphethiloli, okuyinto engeke ihlukaniswe nokusekelwa kobuchwepheshe be-VVT.

Injini ye-VVT ihlukile kunenjini ejwayelekile, okokuqala, ukwakheka kwesekethe yamafutha kubaluleke kakhulu, ngoba lapho kulungiswa i-valve kusengaphambili kanye ne-Angle yokubambezeleka, ukusebenza kuqedwa ngokukhushulwa kwamafutha.

Ukuze kuqinisekiswe ukuthi i-VVT ingasebenza ngesikhathi nangendlela enembile, injini ye-VVT inezidingo eziphakeme kakhulu zokungena kwamanzi kawoyela.

Uma i-viscosity kawoyela iphezulu kakhulu, izokwenza injini ye-VVT isebenze kade, ngakho injini enevalvu yesikhathi eguquguqukayo kufanele isebenzise ukumelana ne-roll ephansi kanye nowoyela ogeleza kakhulu. Ngale ndlela, uwoyela we-0W-20 uye waba yisinqumo sokuqala esinconyelwe izimoto zaseJapan.

Ingxenye yokunemba okuphezulu

I-Automotive camshaft iyingcindezi yokusebenza kwenjini iyona ndlela enkulu kunazo zonke, isimo esisebenzayo sisliding friction, ukumelana nokugijima kukhulu, ukunemba kokucubungula kwe-camshaft kuthinta ukusebenza kwenjini namandla okukhipha amandla, ngakho kudinga ukunemba okuphezulu kakhulu kokucubungula.

Abakhiqizi bezimoto base-Japan ngobuchwepheshe bokucubungula ukunemba ukuze baphathe iphephabhuku le-camshaft njengokushelela njengesibuko, indawo yejenali ebushelelezi ngokwedlulele ku-viscosity yezidingo zikawoyela wokugcoba iyancipha kakhulu.

Injini isebenza ezingeni lokushisa eliphansi

Idizayini eyenziwe kahle yemoto yaseJapan yenza injini isebenze emazingeni okushisa aphansi, okuyisimo esibaluleke kakhulu sokusebenzisa uwoyela one-viscosity ephansi.

I-Beijing ithimba lezobuchwepheshe lesikhungo sokucwaninga uwoyela ngokuhlolwa kokushayela, futhi ngesivinini samakhilomitha ayi-100 ngehora, uwoyela we-pan kawoyela wezimoto zaseJapan nezaseKorea ukhombisa ukuthi izinga lokushisa liphansi kakhulu kunezinga lokushisa lemoto yakwaVolkswagen, imoto yaseJapan. ingaphansi kuka-90 ° C, imoto Volkswagen iseduze 110 ° C.

Ngokuhlolwa, kuphetha ngokuthi ukushisa kwenjini kuphansi kuyimbangela yemoto yaseJapane engasebenzisa uwoyela we-viscosity ophansi, amaJapane kanye nenjini endala yeVolkswagen ngokulandelana zisebenzisa i-viscosity kawoyela 5w20, 5W40, izinga lokushisa elisebenzayo lenjini. I-90 ° kanye ne-110 ° inkomba ye-viscosity yamafutha isafana, umphumela wokuvikela ukugcotshwa muhle.

Amafutha e-viscosity aphansi abheke emgomweni wokonga amandla nokonga uphethiloli, futhi sekunesikhathi eside ekhathazekile futhi efundwa ama-Ovens aseJapane;

Amafutha e-viscosity aphansi ngokuvamile asebenzisa amafutha esisekelo enziwe ngokugcwele anokuqina okuphezulu futhi ahlanganiswe nezithasiselo ezenziwe ngokukhethekile.

Amafutha ane-viscosity ephansi kufanele ahlanganiswe nezingxenye zenjini ezinemba kakhulu;

Kodwa-ke, akunconywa ukushintsha ngokungaboni uwoyela we-viscosity ephansi ukuze wonge uphethiloli, odinga ukuhluka ngemoto. Ukukhethwa kwamafutha emoto, okufanelekile okubaluleke kakhulu!
