Umbhobho omtsha we-Injector Dlla146p2324 0433172324 ye-0445110 ii-Injector

Njengoko uxinzelelo lwamafutha lusanda, izinga lokuvuza kwefilimu yeoli kwisithuba esiphakathi kweendawo ezidibanisa ivalve yenaliti liyenyuka. Izinga lokutshintsha kweqondo lokuvuza elihambelana nendlela enye yokudibanisa ulwelo-oluqilima lihlala lingatshintshi, ngelixa izinga lokuvuza elihambelana nokubalo lokuhlangana kwe-thermal-fluid-solid kunye novavanyo lwe-static lunomohluko omncinci kunye novavanyo loxinzelelo, ukudibanisa i-thermal-fluid-solid, kunye nolunye. -indlela yokudibanisa ulwelo oluqinileyo. Xa uxinzelelo lwamafutha lukhula, ukushisa kwefilimu yeoli kwi-gap kwandisa, kwaye i-deformation elastic kunye ne-thermal deformation yanda. Umahluko phakathi kweziphumo zokubala ezidityanisiweyo kunye neziphumo zovavanyo uya ucaca ngakumbi. Ngoko ke, ukuguqulwa kwe-thermal yendibano yevalve yenaliti ebangelwa ukunyuka kweqondo lokushisa kweoli yeoli ayinakuhoywa xa kuyilwa indibano yevalve yenaliti ye-injector fuel. Ukukhethwa kwempahla yendibano yevalve yenaliti, inaliti Ukugqithiselwa kobushushu okwandisiweyo kwe-valve coupler, imbuyekezo yoguqulo lwe-coupler yevalve yenaliti, njl.njl. ukunciphisa isantya sokutshintsha kokunyuka kokuvuza okubangelwa kukuguquka kwe-thermal ye-valve coupler yenaliti yonyuka ngokuthe ngcembe. , oko kukuthi, iimpawu zokutywina ze-coupler yevalve yenaliti zikhawuleza ukuba ziwohloke. Xa i-fuel pressure iphantsi, kukho umahluko omncinane phakathi kokudityaniswa kwe-heat-fluid-solid kunye ne-unidirectional fluid-solid coupling. Oku kungenxa yokuba i-elastic deformation yokudibanisa i-valve yenaliti incinci kuxinzelelo oluphantsi, kwaye ubushushu befilimu yeoli kwi-gap iphantsi, ngoko ke i-thermal deformation yokudibanisa i-valve yenaliti incinci. Xa uxinzelelo lwamafutha luphakama, ukushisa kwefilimu yeoli kwi-gap kuphakama, kwaye i-elastic deformation kunye ne-thermal deformation iyanda. Umahluko phakathi kweziphumo zokubala ezidityanisiweyo kunye neziphumo zovavanyo ucace ngakumbi nangakumbi. Ngoko ke, ukuguqulwa kwe-thermal yendibano yevalve yenaliti ebangelwa ukunyuka kweqondo lokushisa kweoli yeoli ayinakuhoywa xa kuyilwa indibano yevalve yenaliti ye-injector fuel. Ukhetho lwemathiriyeli yendibano yevalve yenaliti, inaliti Ukudluliselwa kobushushu okwandisiweyo kwesibini sevalvu, ukuguqulwa kwembuyekezo yesibini sevalve yenaliti, njl njl. Ngoxinzelelo oluphezulu, i-deformation elastic kunye ne-thermal deformation yokudibanisa i-valve yenaliti ayinakuhoywa.
