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

Xa kuthelekiswa nophando lovavanyo, ukulinganisa kwamanani kukhulile, ngoko ke indlela yokulinganisa amanani yindlela efanelekileyo yokufunda ukuhamba kwe-cavitation kwi-injector ye-injini ye-diesel ephezulu, kwaye inokubonelela ngolwazi oluxabisekileyo lophando. Ukuza kuthi ga ngoku, abaphengululi baye benza uphando malunga nokuveliswa kunye nokuphuhliswa kwe-cavitation ngaphakathi kwe-diesel injector ngokusebenzisa indlela yokulinganisa amanani, ejoliswe kwiimodeli zokubala ze-cavitation ezahlukeneyo, i-nozzle geometry, iimeko zokusebenza kunye nezinye izinto, kwaye baye benza inkqubela ebalulekileyo yophando. Inokufumaneka kwezi modeli ukuba umphezulu wodonga olugudileyo wamkelwa kunyango lomphezulu wodonga. Enyanisweni, udonga lwangaphakathi lombhobho ludonga olurhabaxa. Ngenxa yoxinzelelo oluphezulu kunye neempawu zesantya esiphezulu se-fluid kwi-injector, kuya kubakho uxinzelelo oluphezulu lwe-shear kufuphi nodonga olubi, oluya kuvelisa ukuphazamiseka okongeziweyo kwisantya kunye noxinzelelo. Nangona kunjalo, indlela yempembelelo yolu kuphazamiseka kwiimpawu zokuhamba kwe-cavitation kwi-injector ayicacanga. Ngokuseka imodeli yeemathematika ezifanelekileyo ukulinganisa ukuhamba kwe-cavitation ngaphakathi kwi-injector ye-diesel, iiparitha ezingenamlinganiselo ezifana ne-cavitation parameter K kunye ne-flow coefficient Cd zisetyenziselwa ukuchaza iimpawu zokuhamba kwe-cavitation ngaphakathi kwi-nozzle, kunye nefuthe lobunzima bodonga ekuhambeni kobuninzi, ukuhanjiswa kwesigaba segesi kunye nokuhanjiswa kwesantya ngaphakathi kumbhobho kuphononongwa.

1) Xa uxinzelelo lwe-inlet luphantsi, i-coefficient yokuhamba iyancipha ngokunyuka kobunzima; Xa uxinzelelo lwe-inlet lukhulu, impembelelo yobunzima kwi-coefficient yokuhamba incinci.

I-2) I-coefficient yokuhamba inyuka ngokukhawuleza ngokunyuka kwepharamitha ye-cavitation. Xa iparameter ye-cavitation inkulu kunexabiso elithile, i-coefficient yokuhamba ngokusisiseko ayisayi kutshintsha kunye ne-cavitation parameter.
