Diesel Injector Fuel Injector 0445110845 Bosch yeQingling

(1) Kana iyo injector solenoid valve isati yatanga, chigaro chebhora chevharuvhu chinotsikirira vharafu kune gomba rekudonhedza mafuta rechigaro chevhavha, gomba rekudonhedza mafuta rakavharwa, uye njanji yakajairika yakakwira-kumanikidza mafuta haigone kupinda muchikamu chepamusoro. chechigaro chevharuvhu. Yakajairika njanji high pressure inoumbwa mugomba remuromo. Iyo yakasanganiswa simba rejanji njanji yakakwira kudzvinyirirwa kwekupedzisira kwechiso chekudzora plunger uye chitubu chepfuti chakakwira kupfuura simba rekuvhura repamusoro-kudzvanya mafuta ari kushanda pakoni yevhavhavha yetsono, semhedzisiro, iyo tsono vharafu inomanikidzwa kupinda muchigaro chevharuvhu uye iyo yakakwirira-yekumanikidza chiteshi inoparadzaniswa kubva mukamuri yekupisa, yakavharwa, uye vheji yetsono inoramba yakavharwa.

(2) Kana iyo solenoid valve ikatanga, chidimbu chezvombo uye chigaro chebhora chevhavha chinokwira kumusoro, vheji yebhora inovhura, uye gomba rekudonhedza mafuta rinovhurwa, izvo zvinoita kuti kudonha kwekamuri yekudzora kudonha, semhedzisiro, kudzvanywa kwepiston kunodonhawo, kana kudzvanywa kwepiston uye simba rakasanganiswa remupfuhwira chitubu chadzikira kusvika chadzikira pane kudzvanyirira kuri kuita pane yekumanikidza koni yejekiseni revhavha yetsono (pano kudzvanywa kwemafuta kuchiri. common rail high pressure), vharafu yetsono inovhurwa, uye mafuta anopfapfaidzwa mukamuri yekupisa kuburikidza neburi remuromo. Rudzi urwu rusina kunanga kudzora kweinjector valve yetsono inotora seti ye hydraulic pressure amplification system, nekuti simba rinodiwa kukurumidza kuvhura vharavha yetsono haigone kugadzirwa zvakananga ne solenoid valve, iyo inonzi inonzi control effect inodiwa kuvhura iyo. tsono vharafu ndeyekuvhura gomba rekudonhedza oiri kuburikidza nesolenoid vharafu kuderedza kudzvanywa kwekamuri yekudzora, nekudaro kuvhura vharafu yetsono.

(3) Kana iyo solenoid valve isati yatanga nekudzima kwesimba, simba rechirimo revharuvhu ye solenoid ichaita kuti chivharo chesimbi uye chigaro chebhora chitsikirwe pasi, uye vharafu yebhora inovhara gomba rekudonhedza mafuta. Mushure mekunge gomba rekudonhedza mafuta ravharwa, mafuta anopinda muvharuvha yekudzora mhango kubva mugomba remafuta kuti agadzirise kudzvanywa kwemafuta, kudzvanywa uku ndiko kudzvanywa kwenjanji, kumanikidza uku kunobata pachiso cheplunger kuburitsa kudzika kudzika, pamwe chete nesimba rinoguma. chepfumbu chitubu chakakura kudarika kudzvanywa kwehutsi hwepamusoro-soro hunoita panhongonya yevharuvhu yetsono mugomba remuromo, kuitira kuti vharafu yetsono ivharwe.

(4) Pamusoro peiyo, nekuda kwekuwanda kwehuturu, kuvuza kuchaitika pavharuvhu yetsono nedzimba, uye aya mafuta akadeuka anoyerera achipinda muchiteshi chemafuta chejekitori kuburikidza negomba rekudzoka kwemafuta.
