Iyini i-turbo yejometri eguquguqukayo futhi isebenza kanjani?
Okuqukethwe
Uma udinga ukusabela okwengeziwe ku-turbo yakho ngaphandle kokudela amandla aphezulu, i-turbo yejometri eguquguqukayo ingaba yilokho okudingayo. Lapha sizokutshela ukuthi iyini i-VGT nokuthi isebenza kanjani, kanye nezinzuzo zayo ngaphezu kwe-turbocharger yejometri engaguquki.
Ama-Turbocharger mahle ngoba amunca amandla angawafuni futhi awasebenzisa ukukhulisa amandla enjini. I-variable Geometry Turbocharger inguqulo ethuthukisiwe yalobu buchwepheshe ehlinzeka ngenani lezinzuzo kanye nokwanda kobunzima. Siyabonga ngevidiyo eyenziwe ngu-KF Turbo ku-Instagram, sibhekisise kabanzi ukuthi yini eyenza i-turbo yejometri eguquguqukayo ikhetheke kangaka.
Isebenza kanjani i-geometry turbocharger?
Ividiyo isibonisa ingaphakathi le-vane turbocharger evamile. Iqukethe isethi yama-blades ahlelwe eduze kwe-exhaust turbine, i-engeli yayo elawulwa yi-actuator. Isibonelo, kuneminye imiklamo enezigwedlo ezihamba phansi naphezulu; zivame kakhulu emishinini esindayo njengamaloli noma ezinye izimoto ezinkulu.
Uyini umehluko phakathi kwe-fixed geometry turbocharger?
Ku-turbocharger evamile yejiyomethri, amagesi e-exhaust adlula ku-turbine futhi ayiphothe, ezungeza i-compressor enamathiselwe edala amandla enjini. Nge-RPM ephansi, injini ayikhiqizi ukugeleza kwe-exhaust okwanele ukuze ijikeleze i-turbine futhi idale amazinga abalulekile okuthuthukisa. Kuleli qophelo, uhlelo kuthiwa lungaphansi komkhawulo we-boost.
Uma injini isifinyelele ku-RPM iphakeme ngokwanele ukuze ikhiqize i-thrust, kusathatha isikhathi ukuzungeza i-turbine ngesivinini esifanele; lokhu kwaziwa ngokuthi yi-turbo lag. I-Turbo lag ne-boost threshold ziphakeme kuma-turbo amakhulu adinga amandla engeziwe ukuze ajikeleze. Nokho, lawa ma-turbine agelezayo aphezulu ayakwazi ukukhiqiza amandla engeziwe. Ukuvumelana, njengezinye izinto eziningi kwezobunjiniyela.
Iyini inzuzo ye-geometry turbocharger eguquguqukayo?
I-turbocharger yejiyomethri eguquguqukayo ifuna ukushintsha lokhu ngokwengeza ama-vanes noma ezinye izakhi ezishintsha ngokusebenza i-geometry yesistimu ye-turbine. Ku-vane turbocharger ezungezayo njengale eboniswe lapha, ama-vanes ahlala evalekile kakhulu ngesivinini esiphansi senjini, okukhawulela ukugeleza kwamagesi akhipha umoya kumavanes. Lo mkhawulo ukhuphula izinga lokugeleza, okusiza amagesi e-exhaust ukuthi asheshise i-turbine ngokushesha. Lokhu kwehlisa i-boost threshold futhi kunciphisa i-turbo lag.
Ukujeziswa kwe-RPM
Kodwa-ke, ukuba nomkhawulo onjalo kungaba inhlawulo enzima kuma-RPM aphezulu, lapho injini idinga ukumpompa amagesi ombhobho ukuze ikhiqize amandla. Kulesi simo, ama-vanes avulekile ukuvumela igesi yokukhipha imfucuza eningi ngangokunokwenzeka ukuthi idlule ku-turbocharger, kugwenywe ukuvinjelwa okungakhuphula ukucindezela emuva nokunciphisa amandla.
Kungani i-turbocharger yejometri eguquguqukayo ilula kakhulu?
Ngakho-ke injini ye-geometry turbo ehamba phambili ngempela kuyo yomibili imihlaba. I-VGT ingakhipha amandla engeziwe ngaphandle kokuhwebelana okujwayelekile kwe-high boost threshold kanye ne-turbo lag evamise ukuza nokusethwa kwe-turbo enkulu. Ukusebenza kahle kukonke nakho kuyathuthukiswa futhi kwezinye izimo ama-blade angasetshenziswa ngisho njengebhuleki lenjini. Ividiyo engezansi iyincazelo enhle yokuthi lobu buchwepheshe busebenza kanjani, ngomdwebo webhodi elimhlophe eliwusizo.
