Kugwiritsa ntchito ma turbocharging pamainjini oyatsira mkati ndikofunikira kuti akwaniritse zofunikira zaposachedwa zamphamvu komanso zotulutsa pama injini akulu a dizilo ndi gasi.Kuti akwaniritse
kusiyana kofunikira, turbocharger ikhoza kupangidwa ndi njira zodutsa ndi zipata, kapena ndi ma turbine geometries (VGT).Kugwiritsa ntchito zipata za zinyalala kumawononga magwiridwe antchito a turbocharger koma kumapereka njira yotsika mtengo komanso yolimba pakusinthasintha kofunikira.Machitidwe ochiritsira a VGT amafunikira kuchuluka kwa zigawo zomwe bulu lililonse limasunthidwa modziyimira pawokha ndi mphete ya actuation ndipo nthawi zina ndi mkono wa lever.
Ngakhale zovuta zake, VGT turbocharging imapereka zabwino zambiri poyerekeza ndi geometry turbocharger yofananira.
mwina kudzaza kwathunthu, kusiya mpata pa ntchito zolemetsa, kapena kufananizidwa ndi katundu wocheperako ndipo zimafuna chipata cha zinyalala.Bukuli limafotokoza kufunikira kokhala ndi nozzle yomwe imatha kusuntha axially kuti igwirizane ndi kupezeka kwa ma depositi komanso kukulitsa kutentha kuti tsambalo lisamamamire.Machitidwe ochiritsira a VGT sanagwiritsidwe ntchito mozama pamapulogalamu omwe mphamvu zambiri, kudalirika kwakukulu ndi moyo wautali zimafunikira chifukwa cha zifukwa zamtengo wapatali ndi zovuta, ndipo pachifukwa ichi zochitika zingapo zakhala zikudziwika kuti zikwaniritse VGT turbocharger yokhala ndi mapangidwe osavuta komanso zigawo zochepa zosuntha. .
Ntchitoyi ikupereka lingaliro latsopano la nozzle ya geometry turbocharger yomwe ingagwiritsidwe ntchito pamasinthidwe a axial ndi ma radial turbocharger.Lingaliroli limapereka kuchepa kwakukulu kwa magawo osuntha ndipo motero ali ndi kuthekera kochepetsera mtengo wa turbocharger ndikuwonjezera kudalirika kwake poyerekeza ndi mapangidwe amtundu wa VGT.Lingaliroli lili ndi nozzle yayikulu ndi tandem nozzle.Iliyonse mwa ma nozzles awa ndi mphete yokhala ndi nambala yofunikira ya vanes.Pochotsa mphuno imodzi molemekeza winayo, ndizotheka kusintha njira yotuluka ya mphuno, ndikusintha dera la mmero m'njira yoti kusintha kwa kutuluka kwakukulu komwe kumadutsa pamphuno kungapezeke.
