I-Diesel Injector Fuel Injector 095000-5351 Denso Injector ye-Isuzu

Uprofesa wenjini evuthayo yangaphakathi e-RWTH Aachen University uklame isampula "HiFORS" (umfutho ophezulu/ukuvulwa ngokushesha/ukubumba umjovo ovamile) walokhu kusetshenziswa, Ithuthukiswe ngokuhlanganisa ingcindezi yomjovo ifike ku-250 MPa nokubumba komjovo ngokuguquguquka okuhle isikhathi esifushane sokuvula nokuvala ukuze ugweme i-throttle engalungile yesihlalo senaliti ngangokunokwenzeka. Nakuba imboni yezimoto okwamanje izibophezele ekuthuthukiseni iphethini yomjovo ongaqhubeki, kodwa ithuthukise ukumodela okuqhubekayo ngephethini yomjovo wesakhiwo semodular yama-injection kaphethiloli, uma kuqhathaniswa nama-injection kaphethiloli endabuko, kunciphisa kakhulu umthelela we-pressure chamber throttling ekwakhekeni kwengxube.

Uhlelo lwe-modularization lomjovo wamafutha

Umjovo we-HiFORS wathuthukiswa ukuze uhlanganise ukuguquguquka kwedizayini okuphezulu kwamaskimu wezingxenye ze-modular nokuguquguquka kwemisebenzi yomjovo kaphethiloli, nemisebenzi yomjovo kaphethiloli ngamunye osetshenziswa ngamamojula ahlukene. I-HiFORS fuel injector ingahlukaniswa ngamamojula amathathu ayinhloko: imojula yokushayela, imoduli ye-servo hydraulic kanye nemojula yokujova uphethiloli. Lawa mamojula axhumene namanye ngokubopha imikhono ukuze kuqinisekiswe ingcindezi yokuxhumana ephezulu ngokwanele ngisho nangaphansi kwengcindezi ephezulu yomjovo. I-drive assembly igoqwe isixhumi, esibuye sibe nesiteshi sokungenisa uwoyela ocindezela kakhulu, isiteshi sokubuyisela uwoyela, ipulaki kagesi yenzwa ehlanganisiwe kanye ne-actuator ye-piezoelectric. Ukuze kuqinisekiswe ukuqhathaniswa nomjovo wokukhiqiza ngobuningi, kusetshenziswa i-injector yokukhiqiza ngobuningi. Ukwelulwa kwe-stroke ye-piezoelectric element kusixhumi kudluliselwa engxenyeni ye-servo hydraulic ngokushesha ngemuva kwemojula yoguquko.

Ingxenye ye-servo hydraulic ingaguqula umumo wephethini yomjovo. I-valve ye-piezoelectric (i-valve yokulawula ngaphambili) iguqula ukushaywa kwesandiso semojula ye-piezoelectric ibe ingcindezi yokulawula, elawula i-valve eyinhloko bese idlulisela ukucindezela komjovo ekuhlanganiseni kwe-nozzle.
