New Injector Nozzle Dlla140p1790 0433172092 ye Fuel Injector 0445120141

1. Tembiricha yemafuta mugap pakati petsono vharafu yekubatanidza zvikamu:

Kana vharafu yetsono ichidzokororwa, iyo kinetic simba yakarasika neshear inoyerera friction pakati petsono valve vaviri uye gap mafuta inoshandurwa kuita simba rekupisa, tembiricha yemafuta gap firimu inokwira zvishoma nezvishoma, uye mafuta anowedzera kana tembiricha yakwira, kuitira kuti pave nekuwedzera kudzvanywa pane gap oiri firimu Munda, huwandu hwemutoro hwefirimu remafuta hunowedzera, chiitiko ichi ndicho chinokonzera kupisa. Kana kuyerera kweshear kusingatariswe, kuyerera kwemafuta kunoderedzwa nekuda kwemadziro viscous resistance. Kana vharafu yetsono yakamira kana kufamba nekumhanya kwakaderera, kupera kwekumanikidza kwemafuta kunoshandurwa kuita simba rekupisa. Munguva pfupi, kupisa kwakaoma kuendesa kumadziro akasimba, saka inorerutswa seadiabatic process. Nekuda kwekukakavadzana kwekuyerera kwemafuta shear, kudziya kwemafuta kunowedzera uye kunowedzera kuumba imwe nzvimbo yekumanikidza, iyo inoita kuti kuyerera kwemafuta, kunonzi kupisa wedge kuyerera. Ukobvu hwefirimu remafuta hunokanganisa kutakura kwekukwira kwekushisa kwefirimu remafuta. Sezvo kukora kwefirimu remafuta kunowedzera kuderera, kutonhora kunokwira uye simba rekutakura rinowedzera zvishoma nezvishoma.

2. Kupesvedzera kwezvigadziro zvemaitiro evhavhavha yetsono pakubatanidza maitiro ekuisa chisimbiso

Kune jekiseni, nekuda kwehuwandu hudiki hwetangi remafuta, kuvharika kwekuita kwevhavhavha yekubatanidza kunoderedzwa, izvo zvinozoderedza zvakanyanya kudzvanywa mukamuri yekumanikidza yenozzle. Naizvozvo, gaka rinonzwisisika rakakosha zvakanyanya kune yekuisa chisimbiso maitiro eiyo tsono yekubatanidza valve. Tichifunga nezve tekinoroji yekugadzirisa uye kurasikirwa kwekudonha panguva ino, kazhinji tora 2 ~ 4μm.
