New Diesel Fuel Injector 28490086 yeJmc Transit Qingling

Majekiseni emafuta einjini yedhiziri yepakati nediki anowanzo kuve nemhando mbiri: pintle type uye porous type. Axial tsono majekiseni anoshandiswa muvortex kana pre-combustion combustion chambers. Huwandu hwemaburi ejekiseni ndeye 1, uye iyo aperture dhayamita iri pamusoro pe1mm. Iri rudzi rwejekiseni rinoshanda zvakavimbika, uye maburi ejekiseni haasi nyore kuvharwa nekabhoni deposits, asi kupisa kwekushisa kwakaderera uye kushandiswa kwemafuta kwakakwirira. Dzimba 125 dzakatevedzana uye 146 dzakatevedzana injini dzedhiziri ndezvechikamu ichi. Multi-hole injectors inoshandiswa mumakamuri ekupisa majekiseni. Inogona kupfapfaidza akati wandei nematepi madiki uye kureba. Iri rudzi rwejekiseni rine hupamhi hwekupisa kwemafuta uye rinonyanya kushandisa mafuta. Iyo jekiseni yemafuta yemumba 135 yakatevedzana dizeli ine akawanda maburi maburi ane dhayamita ye0.35mm. Iyo tsono yevharuvhu yekubatanidza yejekitori yemafuta inonyatso, uye kuenderana kwayo kubvumidzwa ingori 0.002 ~ 0.004mm. Kana pane kusvibiswa mumafuta edhiziri, valve yetsono inenge yakanamatira. Mukuwedzera, musoro weinjector yemafuta yave ichisangana nepamusoro-tembiricha uye yakakwirira-kudzvanywa gasi mukamuri rinopisa kwenguva yakareba, zvichiita kuti vheji yetsono iwedzere zvishoma nezvishoma uye inokanganisa, uye inokanganisa kushanda kwakajairika kweiyo locomotive. Kana jekiseni riri kushanda, iyo yekuvharisa koni pamusoro pemuviri wetsono yevharuvhu inowanzobatwa nevhavhavha yetsono, pamwe chete nekuenderera mberi kwejekiseni rekuyerera kwemafuta e-high-pressure kubva panzvimbo ino, iyo cone surface ichaita semakwara uye mavara - zvishoma nezvishoma anorasikirwa kuvhara, uye kutanga kudonha mafuta. Kana tembiricha yemuchina yadzikira, pombi yepombi inoburitsa chiutsi chichena, uye kana tembiricha yemuchina yakwira, inoshanduka kuita utsi hutema, uye dzimwe nguva pombi yepombi inoburitsa ruzha rusina kujairika.
