Inothi lokufunda le-VGT turbocharger

Wonke amamephu we-compressor ahlolwa ngosizo lwemibandela etholakala ngesikhathi sokuhlaziywa kwezidingo.Kungaboniswa ukuthi asikho i-vaned diffuser enyusa ukusebenza kahle kwe-compressor ebangeni eliyinhloko lokushayela kuyilapho kugcinwa ukuqina kokuhlinzwa okuyisisekelo nokusebenza kahle kwamandla enjini elinganiselwe.Lokhu kuwumphumela wokwehliswa kobubanzi bemephu lapho kusetshenziswa i-vaned diffuser.Imiphumela iphinda ikhombise ukuthi awukho umthelela kokokufaka komsebenzi othile we-impeller uma kusetshenziswa isihlukanisi esinamapharamitha omklamo wobubanzi obunikeziwe.Isivinini se-impeller esilinganisweni sengcindezi esinikeziwe siwumsebenzi kuphela womehluko osebenza kahle obekwe ukusetshenziswa kwe-vaned diffuser.Ngakho-ke umgomo wejiyomethri ye-compressor eguquguqukayo uchazwa njengokugcina inzuzo esebenza kahle ebangeni eliyinhloko lokushayela kuyilapho inweba ububanzi bemephu ukuze ifinyelele ekuqhumeni nokuminyanisa ukugeleza kwe-vaneless diffuser ukuze kutholwe ukusebenza kahle kwamandla alinganiselwe, i-torque ephakeme kanye nesikhathi. ukusebenza kwamabhuleki enjini afana ne-compressor eyisisekelo.

Ama-compressor amathathu aguquguqukayo athuthukisiwe ngenhloso yokuthuthukisa ukonga kukaphethiloli ezinjinini ezisindayo emkhakheni wokushayela omkhulu ngaphandle kokuwohloka mayelana namandla alinganiselwe,

i-torque ephezulu, ukuqina kokuqina nokuqina.Esinyathelweni sokuqala, izidingo zenjini maqondana nesiteji se-compressor ziye zatholwa futhi izindawo zokusebenza ze-compressor ezifanele kakhulu zikhonjiwe.Uhlu lokushayela oluyinhloko lwamaloli ahamba isikhathi eside luhambisana namaphoyinti okusebenza ngezilinganiso zokucindezela okukhulu nokugeleza kwesisindo esiphansi.Ukulahleka kwe-aerodynamic ngenxa yama-engeli agelezayo athinta kakhulu ku-vaneless diffuser kudlala indima enkulu kulobu bubanzi bokusebenza.

Ukuze kuthuthukiswe ukonga kukaphethiloli ngaphandle kokuzinikela ngokuphathelene nezingqinamba ezisele zenjini, kwethulwa amajiyometri aguquguqukayo ukuze kunwetshwe ububanzi bemephu futhi ngesikhathi esifanayo asenze sibe nempumelelo ethuthukisiwe ye-compressor ezilinganisweni zokucindezela okuphezulu kwama-vaned diffuser.
