Viscosity amafutha kanye nethonya layo phezu injini yemoto

Noma yiluphi uketshezi has a viscosity, kuba lesi sici inquma fluidity yayo. uwoyela Izithuthi senzelwe ukwenza ezihlukahlukene imisebenzi ngakho ipharamitha ngamunye has umthelela wabo nekhwalithi isiyonke. Viscosity amafutha iyathinteka.

The main nenkinga yezobuchwepheshe kwanoma iyiphi amafutha engine - ukumisa ngomshikisho ukuthuthela izingxenye ngesikhatsi operation injini. Kahle kahle, amandla ngomshikisho kufanele kube sakugcina ngamafutha ukuqina okusezingeni eliphezulu, impahla yayo kufanele ahlale njalo phezu ububanzi lokushisa ububanzi.

Ukuze kufezekiswe lo mbono umkhuba, futhi udale into elihlangabezana nazo zonke izidingo, kunzima kakhulu. Ngaphezu kwalokho, sicela uqaphele ukuthi ngesikhathi ukunyakaza umthwalo kushintsha njalo, futhi izinga lokushisa amafutha engine yezimoto kuzohluka kakhulu, kwezinye izikhathi ngeke sifinyelele 140-150 degrees.

Nokho, ochwepheshe njalo sisebenzela ukwakha amafutha engine, obekungadala eduze ezakhiweni yayo imingcele edingekayo. Isayensi iye kule ndawo ngempela isinyathelo phambili, ngakho izinjini yesimanje zinamandla kakhulu futhi ngempumelelo kuka ezazingaphambi kwayo, futhi basebenza isikhathi eside.

I viscosity uwoyela ingenye nemingcele ezibaluleke kakhulu. Nakuba injini kubanda noma ayisebenzi at zigcwele, amafutha injini useqala ukushwaqa. Kule ndaba kukhona isidingo sokuthi lawo mafutha kwakufanele aqhubeke ewuketshezi ngaphansi kwanoma yiziphi izimo, ngisho noma izinga lokushisa ngaphandle kahle ngaphansi kwezingaqhwa. I fluidity kangcono amafutha, ngcono ke uzovikela injini ngesikhatsi kokuhlinzwa.

Inkomba viscosity

Ukuze sithole viscosity amafutha, ochwepheshe sethule Inkomba ekhethekile, okutshengisa ukwencika nemingcele main (kuhlanganise viscosity) lokushisa. Ayanda Inkomba, ngcono amafutha igcina fluidity yayo ngisho okushisa aphansi.

I kumele uwoyela ngaphansi kwazo zonke izimo, wahlala phezu injini izingxenye, kodwa ngesikhathi esifanayo ulondoloze flow yayo. Amafutha ngezigaba ngokuvamile kwenziwa Inkomba, njengoba ingenye izinkomba ezibaluleke kakhulu, okuyinto ngezinga elithile kubonisa izimfanelo eziyinhloko.

5W Inkomba ubonisa ukuthi injini kungenziwa run ngisho ezingeni lokushisa - degrees 35 ngaphandle preheating. I ephansi izinga lokushisa, amafutha luthe ukuqina iyoba, futhi kunzima ukuba "ukuqondisa" injini, lokhu kusho ukuthi ukuziqalela ayikwazi crank injini. Uma ukhetha uwoyela ethile motor kufanele njalo ukugxila imisebenzi esemqoka, kodwa ungakhohlwa izincomo izimoto yomenzi. Kuyadingeka ukuba acabangele Umklamo injini, degree of ukuwohloka, tindlela ezivamile wokusebenza, nokunye.

Engine kahle

Ngaphezu kwalokho, viscosity uwoyela kuthinta ukusebenza injini, okungukuthi amandla wokusabalalisa. Lapho injini iyasebenza ezinye amandla ichithwa siqu izidingo zayo zangaphakathi, isb lokhu kusho ukuthi motor kudinga amandla ukuba banqobe amabutho kokukhuhlana zingaveli izingxenye contact ezahlukene. I kangcono futhi ngokuyimpumelelo bekuyoba amafutha, amandla kancane uzobe wazuza kulokho lokhu.

Manje asetshenziswa amafutha ngezigaba, oyifakile-American Society of Izithuthi Onjiniyela. Ukuze uthole omunye isigaba, amafutha kumelwe ahlangabezane nezimfuneko ezithile. viscosity Kinematic of amafutha likalwa ezingeni 40 no-100-degree, futhi kukalwa ngidlula tube ekhethekile lwalugobile - viscometer. Ngesisekelo le kunqunywa viscosity langempela amafutha, okuyinto esetshenziswa ukukhomba ifomula ekhethekile. Lolo vivinyo ukunquma izinga lamafutha, kanye esigabeni esehlukile ezithile.
