Umgangatho oPhezulu weDizili yesitofu seFuel Nozzle Dlla155s529 ye-Deutz Tcd7.8 L6

Ifom ye-wave yoxinzelelo imiselwe ngokuthe ngqo yinkqubo yokutofa, eyona nto ibonakalisa umqondiso ochanekileyo wenkqubo yokutofa amafutha. Ukuba i-injector isebenza ngokungaqhelekanga, ukuguquguquka koxinzelelo kuya kuba yinto engaqhelekanga, ngoko ke uphawu loxinzelelo lungasetyenziselwa ukuxilongwa kwephutha le-injector. Ngenxa yobume obuntsonkothileyo bangaphakathi bombhobho kunye nesithuba esimxinwa kakhulu, ukufakela inzwa yoxinzelelo kumbhobho konakalisa ngokugqithisileyo ubume bombhobho, okunokubangela ukuba i-injector ingaphumeleli ukusebenza ngokuqhelekileyo. Misela inzwa yoxinzelelo ekupheleni koxhulumaniso phakathi kombhobho we-oyile ephezulu kunye ne-injector, kwaye usebenzise uxinzelelo ekupheleni kombhobho we-oyile woxinzelelo oluphezulu ukuze ubeke indawo yoxinzelelo lwe-inlet ye-injector.

Njengoko ixesha lokutofa likhula, ukufuduka kwevalve yenaliti kwanda, okukhokelela ekunyukeni kwendawo yokuhamba kwi-nozzle kunye nokunyuka kwe-coefficient yokuhamba kwe-nozzle. Ngokunyuka koxinzelelo lwenaliti, isantya sokuvula sevalve yenaliti siyakhawuleza kwaye ixesha lokuhlala libambezelekile, okukhokelela kwixesha elide lenaliti, kunye nokwanda kwevolumu yokutofa ngaphandle kombhobho, okukhokelela ekunyukeni ngakumbi. kwi-flow coefficient. Ngaphantsi kwemeko yexabiso elincinci lokutofa kwe-fuel, uxinzelelo lwe-injection ye-fuel inefuthe elikhulu kwi-peak of flow coefficient. Xa i-fuel injection pressure iphantsi, ixabiso eliphezulu le-coefficient yokuhamba phakathi kwe-0.20 kunye ne-0.45; xa i-fuel injection pressure iphezulu, i-peak of flow coefficient Uluhlu oluphezulu lwenguqu luphakathi kwe-0.30 kunye ne-0.65.
