Diesel Injector Fuel Injector 0445120264 Bosch for Foton Auv Bus Auman Forland Aumark 2000 Cummns 150t1

Imwe yeanonyanya kukosha ivharuvhu yetsono uye muviri wetsono wakagadzirwa nemhando yepamusoro inotakura simbi (inowanzozivikanwa semafuta jekiseni nozzle kana mafuta jekiseni musoro), vaviri pamwechete vakadana tsono vharafu vaviri. Kana jekiseni richishanda, mafuta edhiziri akakwira kubva papombi yejekiseni anopinda mujekiseni kuburikidza nejoinhi yechubhu, yobva yapinda mu annular high pressure oil room iri pakati pemuviri wetsono yevharuvhu kuburikidza neoiri inlet chiteshi pane injector body. Kudzvanywa kwemafuta kunobata pane yekumanikidza koni yevharuvhu yetsono uye inoumba kumusoro axial kukanda pavharuvhu yetsono. Kana kusunda kwakakura kudarika pre-kuomesa dzvinyiriro yedzvinyiriro inodzora chitubu uye simba rekukwesha pakati pevaviri vetsono (iyo idiki kwazvo). Ivhavhavha yetsono inokwidziridzwa kumusoro, iyo yekuvharisa koni yekumucheto kwezasi kwevharuvhu yetsono inobviswa kubva kune conical mhete yemuviri wetsono, uye gomba rejekiseni rinovhurwa, kuitira kuti mafuta edhiziri apinzwe mukamuri yekupisa pa. high pressure. Kana pombi yejekiseni yemafuta ichimira kugovera oiri, kudzvanywa kwemafuta ekumanikidza kwepamusoro kunodonha nekukurumidza, uye vharafu yetsono inodzoka nekufamba kwenguva pasi pechiito chekumanikidza chinodzora chitubu kuvhara gomba rejeti. Huwandu hwemaburi eiyo orifice injector yakakura (kazhinji 1 ~ 8), iyo dhayamita yeorifice idiki (kazhinji 0.2 ~ 0.8mm), kudzvanywa kwejekiseni kwakakwira (kazhinji 17 ~ 22MPa), kugona kuzvichenesa ndiko. varombo (iyo orifice iri nyore kuunganidza kabhoni uye plug), uye mhando yedhiziri sefa yakakwira. Iyo yakakodzera kune yakananga jekiseni combustion chamber iyo inoda yakakwirira yekupfapfaidza mhando. Semuyenzaniso, 5-gomba rakavharwa mafuta jekiseni rinoshandiswa muCA6110-2 dhiziri injini ine dhayamita ye0.32mm uye jekiseni pressure ye17.2MPa.
