I-Diesel Injector Fuel Injector 0445120332 Bosch ye-Cummins 6.7 injini

thayipha isakhiwo somjovo
Umjovo wohlobo lwembobo unezimbobo ezingu-1~7 ezinobubanzi obungu-0.15~0.70 mm, ongafafaza i-engeli ethile yekhoni futhi inobubanzi obude. Ukukhethwa kohlobo lwembobo kufanele kunqunywe uhlobo lwegumbi lomlilo. Ngokwesibonelo, injini 6120 diesel isebenzisa injector izimbobo ezimbili ububanzi imbobo 0.4 mm kanye ingcindezi umjovo 17-150 kPa. Injini engu-6135 iyigumbi elivuthayo elimise okwe-@ esebenzisa i-injector enezimbobo ezi-4 enobubanzi bembobo engu-0.35 mm kanye nomfutho womjovo ongu-16 660 kPa. Isakhiwo somjovo wembobo ikakhulukazi sakhiwe umzimba womjovo, ikholi yomjovo kaphethiloli, i-valve yekhoni yomjovo kaphethiloli, umzimba womjovo kaphethiloli, induku ye-ejector, ishubhu elilawula ingcindezi, ijoyinti lokungena likawoyela lesikulufa elilawula ukucindezela, isihlungi. isici kanye nebhowudi yepayipi lokubuyisela uwoyela nokunye. Ingcindezi ekuqaleni komjovo kaphethiloli incike emandleni okuqinisa ngaphambilini entwasahlobo elawula ingcindezi. Ingalungiswa ngesikulufu esilawula ukucindezela. Ngesikhathi sokujova uphethiloli, ingxenye encane yedizili eputshukile izogeleza isuka kuvalvu yenaliti.
Umjovo we-pintle ngokuvamile unembobo yomjovo engu-1 enobubanzi obungu-1 ~ 3 mm. Ngenxa yobubanzi bembobo enkulu, ingcindezi yomjovo kaphethiloli iphansi, ngokuvamile i-9800 ~ 11760 kPa, elungele igumbi elivuthayo elihlukanisiwe. Isakhiwo se-pintle injector kanye ne-orifice injector cishe kuyafana. Umehluko ukuthi i-cone yokuvala i-valve yenaliti inweba ingxenye ye-pintle, futhi ububanzi buncane kunembobo ye-nozzle. I-annular slit yakheka phakathi kwe-pintle nembobo. Izimo ze-pintle ziyi-cylindrical futhi ziyi-conical ehlanekezelwe. Lapho indawo yekhoni yokuvala yevalvu yenaliti ishiya isihlalo sevalvu, umjovo kawoyela uyaqala, futhi ikholomu kawoyela isesimweni sendandatho engenalutho. I-engeli yomjovo ye-pintle e-tapered ehlanekezelwe inkulu ngokuqhathaniswa. Lapho i-fuel injector iqala ukujova uphethiloli futhi isheshe iyeke ukujova uphethiloli, i-pintle isemgodini womjovo, futhi umthamo womjovo kaphethiloli uncane, onganciphisa umsebenzi onzima wenjini ye-diesel futhi unciphise isikhathi sokugcwalisa. Lindela. Lolu hlobo lomjovo kulula ukulucubungula. Imbobo ye-nozzle akulula ukuyivimba. Izindleko zokukhiqiza ziphansi futhi ukwehluleka kuncane.
