Izingxenye ze-Cummins Exhaust Valve 3921444/3802085 Ye-Cummins 6C8.3 Engine

Incazelo Yomkhiqizo

I-valve yakhiwe ngekhanda le-valve nesiqu.Izinga lokushisa lekhanda le-valve liphezulu kakhulu (i-valve yokungena i-570 ~ 670K, i-valve yokukhipha i-1050 ~ 1200K), futhi ithwala ukucindezela kwegesi, amandla e-valve spring kanye namandla e-inertia yezingxenye zokudlulisa.I-lubrication yayo kanye nezimo zokupholisa azilungile, futhi i-valve kufanele idingeke Inamandla athile, ukuqina, ukumelana nokushisa nokumelana nokugqoka.

Umsebenzi we-valve unomthwalo wemfanelo wokufaka umoya enjinini kanye nokuqeda igesi yokukhipha umoya ngemva kokusha.Kusukela esakhiweni senjini, ihlukaniswe i-valve yokungenisa kanye ne-exhaust valve.Umsebenzi we-valve yokudonsa ukumunca umoya enjinini bese uxuba bese ushisa nophethiloli;umsebenzi we-valve yokukhipha ukukhipha igesi yokukhipha eshisiwe futhi uchithe ukushisa.

Ukuze kuthuthukiswe ukusebenza kahle kokuthatha kanye nokukhipha umoya, manje kusetshenziswa ubuchwepheshe obunama-valve amaningi.Kuvamile ukuthi i-cylinder ngayinye ihlelwe ngama-valve angu-4 (kukhona nemiklamo ye-cylinder eyodwa ene-valve engu-3 noma engu-5, isimiso siyafana).Amasilinda ama-4 anamavalvu ayi-16 esewonke.I-"16V" evame ukubonakala ezintweni zemoto isho ukuthi injini inama-valve angu-16 isiyonke.Lolu hlobo lwesakhiwo esinama-valve amaningi kulula ukwakha igumbi elivuthayo elihlangene.Umjovo uhlelwe phakathi nendawo, ongenza ingxube kawoyela negesi ishe ngokushesha nangokulinganayo.Isisindo nokuvulwa kwe-valve ngayinye kuncishiswa ngokufanelekile, ukuze i-valve ivuleke noma ivalwe ngokushesha.
