Diesel Injector Fuel Injector 0445120289 Bosch for Cummins Isbe Isde Qsb6.7

Mumwe muenzaniso ndeye kaviri-gomba rakavharwa mafuta jekiseni rinoshandiswa mu6120 injini yedhiziri. Iyo dhayamita yegomba rejekiseni i 0.42mm uye jekiseni pressure i 17.5M Pa. Nheyo yekushanda yejojo ​​jekiseni yeshaft yakafanana neiyo yegomba jekiseni, chimiro chete chakasiyana: pasi pechisimbiso cone pamucheto wezasi. yevharuvhu yetsono, shaft tsono inobuda kunze kwegomba, uye chimiro chayo chinogona kuchinjika conical kana cylindrical, kuitira kuti muromo ive denderedzwa. slit. Nenzira iyi, iyo jekiseni mbiru ichave isina hollow cone kana column. Saizi yejekiseni gomba remuchinjiko chikamu uye jekiseni cone Angle zvinoenderana nekusimudza uye chimiro cheshaft tsono, saka kugadziridzwa kwechimiro cheshaft tsono kunodiwa kuve kwakanyatso. Shaft tsono jekiseni dhayamita dhayamita yakakura (kazhinji 1 ~ 3mm), jekiseni pressure yakaderera (kazhinji 10 ~ 14MPa), kugona kuzvichenesa kwakasimba (gomba rejekiseni haisi nyore kuunganidza kabhoni uye kuvharika), maitiro ejekiseni akanaka (sangana izvo zvinodikanwa zvekushomeka jekiseni remafuta pakutanga, jekiseni rakawanda remafuta pakati uye kushomeka jekiseni remafuta mune gare gare), Inokodzera vortex kamuri yekupisa kamuri uye precombustion chamber combustion chamber ine yakaderera chinodiwa padhiziri sefa yemhando. Semuenzaniso, dhayamita yenozzle ye 4125A4 injini yedhiziri ndeye 1.5mm uye jekiseni rinomanikidza 12.7M Pa. Tatu, yakaderera inertia mafuta jekiseni yechinyakare mafuta jekiseni tsvimbo yakareba, nzvimbo yekumanikidza inodzora chitubu iri kure nevharuvhu yetsono, kuitira kuti vharafu yetsono kumusoro uye pasi kufamba inertia kuwedzere, kukanganisa kwevhavhavha yetsono pakuvhara conical pamusoro kunowedzera, mhinduro yekunzwa kwetsono. vharafu kuoiri pressure inoderera.
