Tšebeliso ea turbocharging lienjineng tse tukang ka hare ke ea bohlokoa ho fihlela litlhoko tsa morao-rao tsa matla le tlhahiso bakeng sa lienjine tse kholo tsa diesel le khase.E le ho finyella
phapang e hlokahalang, turbocharger e ka raloa ka li-by-pass le liheke tsa litšila, kapa ka li-geometries tsa turbine tse feto-fetohang ka botlalo (VGT).Tšebeliso ea liheke tsa litšila e senya ts'ebetso ea turbocharger empa e fana ka tharollo e theko e tlaase le e matla bakeng sa phapang e hlokahalang.Mekhoa e tloaelehileng ea VGT e hloka palo e kholo ea likarolo tseo ho tsona molomo o mong le o mong o tsamaisoang ka boikemelo ka selikalikoe sa actuation 'me ka linako tse ling ka letsoho la lever.
Leha e rarahane, VGT turbocharging e fana ka melemo e mengata ha e bapisoa le turbocharger e tsitsitseng ea geometry.
e ka ba ho mojaro o felletseng, ho siea lekhalo lits'ebetsong tsa phallo ea karolo, kapa ho tsamaellana le mojaro o sa fellang le ho hloka heke ea litšila.Phatlalatso e hlalosa tlhokahalo ea ho ba le molomo o ka tlosang axially ho amohela boteng ba li-deposit le katoloso ea mocheso ho thibela lehare hore le se ke la khomarela.Sistimi e tloaelehileng ea VGT ha e so sebelisoe haholo lits'ebetsong moo matla a phahameng, ts'epo e phahameng le bophelo bo bolelele bo hlokahalang ka lebaka la litšenyehelo le ho rarahana, 'me ka lebaka lena ho 'nile ha e-ba le liphetoho tse' maloa ho finyella VGT turbocharger e nang le moralo o bonolo le likarolo tse fokolang tse tsamaeang. .
Mosebetsi ona o fana ka maikutlo a macha a nozzle ea geometry turbocharger e ka sebelisoang ho litlhophiso tsa axial le radial turbocharger.Khopolo ena e fana ka phokotso e kholo ea likarolo tse tsamaeang 'me ka hona e na le monyetla oa ho fokotsa litšenyehelo tsa turbocharger le ho eketsa ts'epo ea eona ha e bapisoa le meralo e tloaelehileng ea VGT.Mohopolo ona o na le molomo oa mantlha le molomo oa tandem.E 'ngoe le e' ngoe ea li-nozzles tsena ke selikalikoe se nang le palo e hlokahalang ea li-vanes.Ka ho tlosa nozzle e le 'ngoe mabapi le e' ngoe, hoa khoneha ho fetola sekhahla sa ho phalla ha molomo, le ho fetola sebaka sa 'metso ka tsela eo ho ka finyelloang phetoho ea phallo ea boima e fetang ka har'a molomo.
