I-Diesel Injector Fuel Injector 095000-8730 Denso Injector for Shangchai, Toyota, Hyundai, Mitsubishi Fuso

Uma kuqhathaniswa nocwaningo lokuhlola, ukulingiswa kwezinombolo kuvuthiwe, ngakho-ke indlela yokulingisa izinombolo iyindlela ephumelelayo yokutadisha ukugeleza kwe-cavitation ku-injector ye-high pressure diesel injini, futhi inganikeza ulwazi olubalulekile locwaningo. Kuze kube manje, izazi zenze ucwaningo oluthile ekukhiqizeni nasekuthuthukisweni kwe-cavitation ngaphakathi komjovo wedizili ngokusebenzisa indlela yokulingisa izinombolo, okuhloswe ngayo amamodeli wokubala we-cavitation ahlukene, i-nozzle geometry, izimo zokusebenza nezinye izici, futhi zenze inqubekelaphambili ebalulekile yocwaningo. Kungatholakala kulawa mamodeli ukuthi indawo yodonga olubushelelezi yamukelwa ukwelashwa kwendawo yodonga. Eqinisweni, udonga lwangaphakathi lombhobho luwudonga oluqinile. Ngenxa yokucindezela okukhulu kanye nezici zejubane eliphezulu zoketshezi ku-injector, kuzoba nokucindezeleka okuphezulu kwe-shear eduze kodonga olubi, okuzokhiqiza ukuphazamiseka okwengeziwe kwejubane nokucindezela. Kodwa-ke, indlela yethonya yalokhu kuphazamiseka ezicini zokugeleza kwe-cavitation ku-injector ayicacile. Ngokusungula imodeli yezibalo enengqondo yokulingisa ukugeleza kwe-cavitation ngaphakathi komjovo wedizili, amapharamitha angenasici afana nepharamitha ye-cavitation K kanye ne-flow coefficient Cd isetshenziselwa ukuchaza izici zokugeleza kwe-cavitation ngaphakathi kwe-nozzle, kanye nomthelela wobunzima bodonga ekugelezeni okukhulu, ukusatshalaliswa kwesigaba segesi kanye nokusatshalaliswa kwesivinini ngaphakathi kombhobho kuyafundwa.

I-1) Uma ingcindezi yokungena iphansi, i-coefficient yokugeleza iyancipha ngokunyuka kobunzima; Uma ingcindezi yokungena inkulu, umthelela wobunzima ku-coefficient yokugeleza uncane kakhulu.

I-2) I-coefficient yokugeleza ikhula kancane kancane ngokunyuka kwepharamitha ye-cavitation. Uma ipharamitha ye-cavitation inkulu kunevelu ethile, i-flow coefficient ayisashintshi nepharamitha ye-cavitation.
