Yepamusoro Performance Fuel Injector EJBR01801Z Diesel Injector Yakajairika Rail Injector Injini Zvikamu zveDelphi Auto

Iyo injector nozzle chinhu chakakosha chakanyatso kubatanidza jekiseni remafuta uye atomisation, uye kushanda zvakanaka kweiyo jekiseni remafuta kunokanganisa zvakanyanya nekuyerera maitiro mukati memuromo. Mafuta ari mukamuri yekumanikidza kupinda mukati meinopinza yemuromo, iyo yepakati-chikamu nzvimbo yekuyerera chiteshi chibvumirano, kuyerera kwemafuta kunowedzera, kudzvanywa kwenzvimbo kunoderedzwa kusvika pazasi pe saturation vapor pressure yemafuta, zvichikonzera cavitation. Inoramba ichigadzirwa cavitation bubble inodonha pasi peyakanyanya-kudzvanywa mamiriro, kudonha kweiyo micro-jet uye kukonzeresa kwayo kunokonzerwa nekukanganisa kwemukati wepasi pegomba rekupfapfaidza, nekufamba kwenguva, mukati megomba rekupfapfaidza richaburitsa. kutsemuka uye craters, iyo muromo wemukati kuyerera uye kupfapfaidza atomisation ichakanganiswa, uye mumatambudziko akaoma, muromo unotadza. Naizvozvo, zvakakosha zvikuru kudzidza kuvandudzwa kwecavitation kuyerera mukati memhino uye cavitation kupfeka mukati memadziro emukati pegomba rekupfapfaidza.

Iyo geometrical parameters yemhino ine simba rakakura pane cavitation kuyerera uye cavitation kupfeka.Shervani et al. uye Lee et al. yakagumisa kuburikidza nekuongorora kwekufananidza kuti kuwedzera kwetaper yemuromo kunogona kuderedza zvinobudirira kuitika kwekuputsika kwebubble pane cavitation kupfeka mukati memukati wemuromo, uye kuti kuvimbika kwehuputi kuchavandudzwa. Lee et al. kubva kuHanyang University yakaita ongororo yekuongorora uye yakaona kuti yakakura chiyero chehurefu hwehurefu kusvika dhayamita, iyo yakawanda simba inodiwa kugadzira cavitation, kureva, cavitation inodzvinyirirwa sezvo kureba kwemhino kunowedzera.Brusiania et al. akaenzanisa maitiro e-hydrodynamic e-cylindrical uye conical nozzles uye akawana kuti chiyero chekuyerera kwemukati muconical nozzle chakaderedzwa zvakanyanya, uye kufanana kwese kwekuyerera kunovandudzwa zvakanyanya. Panyaya ye cavitation njodzi kufanotaura, Dular et al. vakagumisa kubva pakuongorora kwavo kuti cavitation mabhubhu pedyo rusvingo achakoromoka asymmetrically, uye kubudisa micro-jet kukanganisa kuyerera kumadziro kurutivi kure kure nemukati madziro emhumhu.Zhang et al. yakatora nyowani cavitation kupfeka kufanotaura modhi zvichibva pane dzidziso yekutamisa huwandu pakati pezvikamu zvakasiyana nekudzidza chiyero chekufambisa pakati pezvikamu zvakasiyana uye ndokuchisimbisa mumuromo wakareruka, asi modhi yacho haina kukwanisa kufanotaura nezve njodzi yecavitation, uye haisi iyo. zvinokwanisika kufanotaura njodzi ye cavitation. Nekudaro, iyo modhi haigone kupa iyo chaiyo quantitative characterization ye cavitation ngozi. Parizvino, kana uchiongorora njodzi yekupfeka kwecavitation mumhino, chinonyanya kutariswa chiri panzvimbo yemuromo iyo cavitation ingangoitika uye pakuongorora dhigirii rekupfeka kwecavitation munzvimbo dzakasiyana mukati memuromo. Zvisinei, hapana kufananidzwa kwehuwandu hwehuwandu hwekupfeka munzvimbo umo cavitation ingangoitika, uye pane kushayikwa kwekutsvakurudza pamusoro pemigumisiro yejometri parameters yemuromo panjodzi yekukuvara kwecavitation.
