I-Diesel Injector Fuel Injector 0445120289 Bosch ye-Cummins Isbe Isde Qsb6.7

Esinye isibonelo isijovo sikaphethiloli esinezimbobo ezimbili esisetshenziswa enjinini kadizili engu-6120. I-diameter yembobo yomjovo ingu-0.42mm futhi ingcindezi yomjovo ingu-17.5M Pa. Umgomo wokusebenza womjovo yenaliti ye-shaft uyafana newomjovo wembobo, isakhiwo kuphela esihlukile: ngaphansi kwekhoni yokuvala ekugcineni engezansi. we-valve yenaliti, inaliti ye-shaft iphuma emgodini, futhi ukwakheka kwayo kungaguqulwa njenge-conical noma i-cylindrical, ukuze umlomo wombhobho ube yindilinga. i-slit. Ngale ndlela, ikholomu yomjovo izoba yikhoni engenalutho noma ikholomu. Ubukhulu besigaba sesiphambano sembobo yomjovo kanye ne-engeli yekhoni yomjovo incike ekuphakameni nasekumeni kwenaliti ye-shaft, ngakho-ke ukucutshungulwa komumo wenaliti ye-shaft kuyadingeka ukuthi kunembile kakhulu. Idayamitha yomjovo womjovo wenaliti yomphini inkulu (imvamisa i-1 ~ 3mm), ingcindezi yomjovo iphansi (imvamisa i-10 ~ 14MPa), ikhono lokuzihlanza liqinile (imbobo yomjovo akulula ukunqwabelanisa ikhabhoni nokuvinjwa), izici zomjovo zinhle (hlangabezana izidingo zomjovo omncane kawoyela ekuqaleni, umjovo kawoyela omningi phakathi kanye nomjovo kawoyela omncane kamuva), Ilungele igumbi lokuvutha kwegumbi le-vortex futhi Igumbi lomlilo elivuthayo elinesidingo esiphansi kukhwalithi yesihlungi sikadizili. Isibonelo, i-diameter ye-nozzle ye-4125A4 injini ye-diesel ingu-1.5mm futhi ingcindezi yomjovo ingu-12.7M Pa. Okuthathu, i-inertia ephansi yesijojo sikaphethiloli wenduku yendabuko yinde, indawo yokulawula ingcindezi intwasahlobo ikude nevalvu yenaliti, ukuze i-valve yenaliti iye phezulu naphansi, i-inertia yokunyakaza ikhuphuke, umthelela we-valve yenaliti endaweni yokuvala i-conical uyakhuphuka, ukuzwela kokuphendula kwenaliti i-valve kuya ku-oyela ingcindezi iyancipha.
