Iko kushandiswa kwe turbocharging painjini dzekupisa kwemukati kwakakosha kusangana neazvino simba uye emission zvinodiwa kune hombe dizeli uye gasi injini.Kuti uwane
kusiyanisa kunodiwa, turbocharger inogona kugadzirwa pamwe nekupfuura uye magedhi emarara, kana neakazara akasiyana turbine geometries (VGT).Kushandiswa kwemagedhi emarara kunokanganisa kuita kweturbocharger asi kunopa mutengo-unoshanda uye wakasimba mhinduro yekusiyana kunodiwa.Yakajairwa VGT masisitimu inoda huwandu hukuru hwezvikamu umo mhuno yega yega inofambiswa yakazvimiririra nemhete yekusimudzira uye dzimwe nguva neruwoko.
Kunyangwe kuoma kwavo, VGT turbocharging inopa mabhenefiti akakosha kana ichienzaniswa neyakagadziriswa geometry turbocharger inofananidzwa.
kungave kuzere kuzara, kusiya mukaha pane chikamu chekutakura zvikumbiro, kana kufananidzwa pachikamu chemutoro uye zvinoda gedhi remarara.Chinyorwa chinotsanangura chinodikanwa chekuve nemuromo unokwanisa kubvisa axially kuti igone kuvepo kwemadhipoziti uye kuwedzera kwemafuta kudzivirira blade kuti isabatike.Yakajairwa VGT masisitimu haasati ashandiswa zvakanyanya kune maapplication uko simba rakakwirira, kuvimbika kwepamusoro uye hupenyu hurefu hunodiwa nekuda kwemitengo uye kuomarara zvikonzero, uye nechikonzero ichi akati wandei akaumbwa kuti awane VGT turbocharger ine nyore dhizaini uye zvishoma zvinofamba zvinhu. .
Iri basa rinopa pfungwa nyowani yekusiyana geometry turbocharger nozzle iyo inogona kuiswa kune axial uye radial turbocharger zvigadziriso.Iyo pfungwa inopa kuderedzwa kwakakosha kwezvikamu zvinofamba uye saka ine mukana wekudzikisa mutengo weturbocharger uye kuwedzera kuvimbika kwayo kana ichienzaniswa neyakajairwa VGT magadzirirwo.Pfungwa yacho ine muromo mukuru uye tandem nozzle.Imwe neimwe yeaya mhuno imhete ine nhamba inodiwa yevane.Nekubvisa imwe muromo neruremekedzo kune imwe, zvinokwanisika kugadzirisa kubuda kwekuyerera kwekona yemuromo, uye kugadzirisa nzvimbo yehuro nenzira iyo kusiyanisa kwekuyerera kwehuwandu hunopfuura nemumuromo kunogona kuwanikwa.
