High Quality Diesel Fuel Injector Nozzle Dlla334n419

Tsvagiridzo pamusoro peKupesvedzera Kwetsono Valve Movement yeDiesel Engine Injector paInjection Characteristics yeGomba rega rega. (chikamu1)

Sezvo kubudiswa kwemafuta nemirau yekushandiswa kwemafuta kunowedzera kuomesa, injini dzinopisa mukati dzinoramba dzichienda kunzvimbo dzakachena, dzinoshanda, uye dzinochengetedza simba.Iyo yakaomesesa emission mirau inoisa kumberi kwepamusoro zvinodiwa kune iyo mafuta ekupa system, uye iyo mafuta jekiseni pressure inogona kusvika kusvika 250MPa kana kutokwira.High-pressure common njanji yave iyo huru mumunda weinjini dzedhiziri nekuda kwehunyanzvi hwayo hwakasarudzika, uye jekiseni remafuta, seiyo terminal actuator inobatanidza kumusoro kwepamusoro-kumanikidza common njanji system uye yakadzika jekiseni remafuta, inozviratidza.Vaviri vetsono yevharuvhu haingotakure basa rekuzora mafuta, kuvhara uye kutenderera, asi zvakare inoita sechikamu chekuuraya chakananga chikamu chejekiseni remafuta, iyo inosarudza hunhu hwejekiseni remafuta uye kupfapfaidza, uyezve inokanganisa inotevera mafuta-gasi kusanganisa mhando uye. emission maitiro.

Mushonga wevharuvhu wetsono unoumbwa nevharuvhu yetsono uye muviri wetsono.Nekuwedzera kunoramba kuchiwedzera kwepamusoro-kumanikidzwa kwakajairika njanji jekiseni, kuyerera kwepamusoro-kudzvanywa kwemafuta mumuromo (inoumbwa neaina valve yetsono, kamuri yekumanikidza, nezvimwewo) kwete chete ine yakakwira Reynolds nhamba Iyo pakarepo mhirizhonga yejeti. inoperekedzwa necavitation inokonzerwa nepulse contraction uye fluid vortex motion, ichigadzira yakaoma gasi-mvura-yeviri-chikamu kuyerera, iyo inokanganisa iyo mafuta atomization kunaka pakubuda kwegomba remuromo.Kubva pane izvi, kubva pakuona kwekufamba kwenguva pfupi kwevhavhavha yetsono, pepa iri rinoongorora simba rekufamba kwenguva dzose (pasina kufunga nezve eccentricity) uye kufamba kusingaenzaniswi (kuchifunga nezve eccentricity) yevhavha yetsono pakuyerera kwemukati uye maitiro ejekiseni ega ega. gomba, uye inogadzira nzira inotarisa kusimba kwemafuta emafuta.Zvichienderana negasi-mvura-maviri-chikamu transonic kuyerera modhi mumhino, izvo zvinopesvedzera zvinhu zve elastic deformation uye eccentric kufamba kwevharuvhu yetsono zvinoongororwa, izvo zvinopa hwaro hwekufungidzira hwekugadzirisa dhizaini nekugadzira jekiseni.
