Choyamba, kayeseleledwe kalikonse ka kayendedwe ka mpweya kudzera pa turbocharger compressor.
Monga tonse tikudziwa, ma compressor akhala akugwiritsidwa ntchito kwambiri ngati njira yabwino yopititsira patsogolo magwiridwe antchito ndikuchepetsa kutulutsa kwa injini za dizilo. Malamulo omwe akuchulukirachulukira otulutsa mpweya komanso kubwereketsa gasi wowonjezera kumapangitsa kuti injiniyo igwire ntchito kumadera osagwira ntchito bwino kapena osakhazikika. Pazimenezi, kuthamanga kwapansi komanso kulemedwa kwakukulu kwa injini za dizilo kumafuna kuti ma compressor a turbocharger apereke mpweya wokwezeka kwambiri pamayendedwe otsika, komabe, magwiridwe antchito a turbocharger compressor nthawi zambiri amakhala ochepa pamikhalidwe yotereyi.
Chifukwa chake, kuwongolera magwiridwe antchito a turbocharger ndikukulitsa magwiridwe antchito okhazikika akukhala kofunika kwambiri pa injini za dizilo zotsika kwambiri zamtsogolo. CFD kayeseleledwe ikuchitika ndi Iwakiri ndi Uchida anasonyeza kuti osakaniza onse casing mankhwala ndi variable kalozera kalozera vanes angapereke lonse opaleshoni osiyanasiyana poyerekeza kuposa ntchito paokha. Njira yokhazikika yogwirira ntchito imasinthidwa kuti ichepetse kuthamanga kwa mpweya pamene liwiro la compressor limachepetsedwa kufika 80,000 rpm. Komabe, pa 80,000 rpm, ntchito yokhazikika yokhazikika imakhala yocheperapo, ndipo chiŵerengero cha kupanikizika chimakhala chochepa; izi makamaka chifukwa cha kuchepa kwa tangential otaya pa chotulukapo.
Kachiwiri, madzi kuzirala dongosolo turbocharger.
Kuchulukirachulukira kwa zoyesayesa zayesedwa kukonza makina oziziritsa kuti akweze zotulukapo pogwiritsa ntchito kwambiri voliyumu yogwira ntchito. Masitepe ofunikira kwambiri pakupitiliraku ndikusintha kuchokera ku (a) mpweya kupita ku kuzirala kwa hydrogen wa jenereta, (b) mosalunjika kupita ku kuzirala kwa kondakitala, ndipo pomaliza (c) haidrojeni kupita ku kuzirala kwa madzi. Madzi ozizira amapita ku mpope kuchokera ku tanki yamadzi yomwe imakonzedwa ngati thanki yamutu pa stator. Kuchokera pa mpope madzi amayamba amayenda mozizira, zosefera, ndi valavu yowongolera mphamvu, kenako amayenda munjira zofananira kudutsa ma stator windings, main bushings, ndi rotor. Pampu yamadzi, limodzi ndi polowera madzi ndi potuluka, zimaphatikizidwa pamutu wolumikizira madzi ozizira. Chifukwa cha mphamvu yawo ya centrifugal, kuthamanga kwa hydraulic kumakhazikitsidwa ndi mizati yamadzi pakati pa mabokosi amadzi ndi ma coils komanso ma radial ducts pakati pa mabokosi amadzi ndi pakati. Monga tanenera kale, kuthamanga kwa kusiyana kwa mizati ya madzi ozizira ndi otentha chifukwa cha kukwera kwa kutentha kwa madzi kumakhala ngati mutu woponderezedwa ndipo kumawonjezera kuchuluka kwa madzi omwe akuyenda muzitsulo molingana ndi kuwonjezeka kwa kutentha kwa madzi ndi mphamvu ya centrifugal.
