Kwiga inyandiko ya VGT turbocharger

Imikoreshereze ya turbuclifike kuri moteri yaka imbere ni ntangarugero kugirango yuzuze ingufu zigezweho n’ibisohoka kuri moteri nini ya mazutu na gaze. Kugirango tubigereho

impinduka zisabwa, turbocharger irashobora gushushanywa haba kumihanda no kumarembo yimyanda, cyangwa hamwe na turbine geometrike ihinduka (VGT). Imikoreshereze y amarembo yimyanda ibangamira imikorere ya turbocharger ariko itanga igisubizo cyigiciro kandi gikomeye kubishobora guhinduka. Sisitemu isanzwe ya VGT isaba umubare munini wibigize aho buri nozzle yimurwa yigenga nimpeta yimikorere kandi rimwe na rimwe nukuboko kwa lever.

Nubwo bigoye, VGT turbocharging itanga inyungu zikomeye ugereranije na geometrike ihamye ya turbocharger ihuye

haba kumuzigo wuzuye, usize icyuho kubice bisabwa imitwaro, cyangwa bihujwe numutwaro wigice kandi bisaba irembo ryimyanda. Igitabo gisobanura icyifuzo cyo kugira uruziga rushobora kwimuka mu buryo bworoshye kugira ngo habeho ububiko no kwagura ubushyuhe kugira ngo icyuma kidahagarara. Sisitemu isanzwe ya VGT ntabwo yakoreshejwe cyane mubisabwa aho imbaraga nyinshi, kwizerwa cyane hamwe nubuzima burebure bisabwa bitewe nigiciro ndetse nimpamvu zigoye, kandi kubwiyi mpamvu hatekerejweho iterambere ryinshi kugirango tugere kuri turbocharger ya VGT ifite igishushanyo cyoroshye kandi kitagenda neza. .

Aka kazi gatanga igitekerezo gishya cya geometrie ihindagurika ya turbocharger nozzle ishobora gukoreshwa muburyo bwa axial na radial turbocharger iboneza. Igitekerezo gitanga igabanuka ryibice byimuka bityo ikaba ifite ubushobozi bwo kugabanya igiciro cya turbocharger no kongera ubwizerwe ugereranije nibisanzwe VGT. Igitekerezo kigizwe nozzle nyamukuru na tandem nozzle. Buri kimwe muri ibyo byuma ni impeta ifite umubare usabwa wa gari ya moshi. Mu kwimura uruziga rumwe kubijyanye nurundi, birashoboka guhindura inguni yo gusohoka yo gusohoka ya nozzle, no guhindura agace k'umuhogo kuburyo itandukaniro ryimyuka myinshi inyura muri nozzle ishobora kugerwaho.
