I-New Injector Nozzle Dlla140p1790 0433172092 ye-Fuel Injector 0445120141

1. Izinga lokushisa likaphethiloli esikhaleni esiphakathi kwezingxenye zokuhlanganisa ivalvu yenaliti:

Lapho i-valve yenaliti iphindaphinda, amandla e-kinetic alahlekelwe ukungqubuzana kokugeleza kwe-shear phakathi kombhangqwana we-valve yenaliti kanye nophethiloli wegebe aguqulwa abe amandla okushisa, izinga lokushisa lefilimu likawoyela we-gap liyenyuka kancane kancane, futhi uphethiloli uzokhula lapho izinga lokushisa likhuphuka, ukuze kube nengcindezi eyengeziwe kwifilimu ye-gap oil Field, umthamo womthwalo wefilimu kawoyela uyanda, lesi simo siwumphumela we-thermal wedge.Uma ukugeleza kwe-shear kungacatshangwa, izinga lokugeleza kwamafutha liyancishiswa ngenxa yokumelana ne-viscous odongeni.Uma i-valve yenaliti imile noma ihamba ngesivinini esiphansi, ukulahlekelwa kwengcindezi kaphethiloli konke kuguqulwa kube amandla okushisa.Ngesikhathi esifushane, ukushisa kunzima ukudlulisela odongeni oluqinile, ngakho-ke kwenziwa lula njengenqubo ye-adiabatic.Ngenxa yokungqubuzana kokugeleza kwe-fuel shear, izinga lokushisa likaphethiloli liyakhula futhi landa ukuze kwakhiwe insimu yokucindezela eyengeziwe, okwenza ukugeleza kukaphethiloli, okubizwa ngokuthi ukugeleza kwe-wedge eshisayo.Ubukhulu befilimu kawoyela buthinta amandla okuthwala ukukhuphuka kwezinga lokushisa kwefilimu kawoyela.Njengoba ubukhulu befilimu kawoyela buba buncane, izinga lokushisa liyakhuphuka futhi umthamo wokuthwala ukhula kancane kancane.

2. Ithonya lamapharamitha esakhiwo sokuhlangana kwevalvu yenaliti ezicini zokuvala

Ngomjovo, ngenxa yomthamo omncane wethangi lamafutha, ukusebenza kokuvalwa kwe-valve yokuhlanganisa inaliti kuyancipha, okuzonciphisa kakhulu ukucindezela ekamelweni lokucindezela le-nozzle.Ngakho-ke, igebe elinengqondo libaluleke kakhulu ezicini zokuvala zokuhlanganisa inaliti ye-valve.Uma ucabangela ubuchwepheshe bokucubungula nokulahlekelwa kokuvuza kulesi sigaba, ngokuvamile kuthatha i-2 ~ 4μm.
