I-New Injector Nozzle Dlla150pn315 ye-Mitsubishi Engine

Inqubo yokugaya ebhanqiwe yamukelwa izingxenye zevalvu yenaliti, futhi ubulukhuni obungaphezulu bungu-.025μm. Ukumataniswa kwe-coupler ye-valve yenaliti kuncane kakhulu, ngokuvamile ku-1 ~ 4μm. Ekusebenzeni kwangempela kombhangqwana we-valve yenaliti, ngenxa yokucindezela okukhulu kukaphethiloli, kanye nokunyakaza okuhlobene nokuguqulwa phakathi kombhangqwana, ukugcoba uketshezi phakathi kombhangqwana kwakhiwa. Ngokombono wokuhlaziywa kwe-lubrication, i-viscosity yamafutha kawoyela inethonya elikhulu ezicini zokugcoba zamafutha kaphethiloli, futhi lapho izimo zokusebenza zihlala njalo, i-viscosity yamafutha okugcoba inquma ubukhulu befilimu yamafutha okugcoba. Ngokusho kwethiyori ye-tribology, ukugcotshwa kokuhlangana kwe-valve yenaliti kuwukugcoba komngcele. Ekugcotshisweni komngcele, ngenxa yokungalingani kwendawo yokukhwelana, ifilimu kawoyela phakathi kweziqongo zokuxhumana ithwala ingxenye yomthwalo, ngakho-ke i-viscosity kaphethiloli inomthelela omkhulu ekugcobiseni nasekuthwaleni umthwalo wokuhlanganisa i-valve yenaliti. .

Ukuhlangana kwevalvu yenaliti kusebenzisa indlela yokuzigcoba ngodizili, futhi ifilimu kawoyela yakheka esikhaleni sokuhlangana sokuhlangana kwevalvu yenaliti ngokusebenzisa ukugeleza kokuvuza kukawoyela we-diesel anengcindezi ephezulu, ukugwema ukuthintana okuqondile kwendawo yokuvala uwoyela. ifilimu. Okuqukethwe kwezinto ezikwazi ukumelana nokugqokwa emafutheni edizili kunquma amandla okugcoba kawoyela wedizili. Kukhona okokugcoba kwemvelo kuwoyela we-diesel, njengama-sulfide nama-polycyclic aromamatic hydrocarbons. Ngenxa yenqubo enokhahlo ye-hydrogenation kanye nokwelashwa kwe-desulfurization evame ukusetshenziswa enqubweni yokukhiqiza udizili, okuqukethwe kwezinhlanganisela ze-polar ezingagqoki kuphansi kakhulu, futhi okuqukethwe kwe-polycyclic kanye ne-bicyclic hydrocarbons enamakha nakho kuncane, ngakho-ke ikhono lokuzigcoba uwoyela udizili ngokuvamile uphansi uma kuqhathaniswa. Umehluko.
