I-geometry ye-turbine eguquguqukayo - ingabe ingcono kunejometri engaguquki?

Izinhlobo zokuqala zama-turbocharger zazilawulwa yingcindezi esetshenziswa ku-wastegate. Lapho umkhawulo we-boost pressure ufinyelelwa, i-valve yavuleka, okuvumela amagesi e-exhaust amaningi ukuba aphumele ku-exhaust. I-geometry ye-turbine eguquguqukayo isebenza ngendlela ehlukile futhi ngaphezu kwalokho ihlanganisa lokho okubizwa ngokuthi. amaphini okuqondisa izigwedlo, okungukuthi izigwedlo. Kumayelana nani? siyaphendula!

Iyini iTurbine yeJiyomethri Eguquguqukayo?

Njengoba kushiwo ngenhla, i-turbine geometry ku-VHT compressors (noma i-VGT noma i-VTG kuye ngomkhiqizi) ingalungiswa noma iguquguquke. Umqondo uwukuphatha amagesi e-exhaust akhiqizwa injini ngendlela ephumelelayo ngangokunokwenzeka. I-turbine ye-VNT inendandatho eyengeziwe ohlangothini olushisayo. Izigwedlo (noma amaphini okuqondisa) abekwe kuwo. I-engeli yokuchezuka kwabo ilawulwa i-vacuum valve. Lawa ma-blades anganciphisa noma andise isikhala sokugeleza kwamagesi e-flue, okuthinta isivinini sokugeleza kwawo. Lokhu kuvumela i-impeller eseceleni eshisayo ukuthi ijikeleze ngokushesha noma ingenzi lutho.

Isebenza kanjani i-turbocharger yejiyomethri engashintshi futhi eguquguqukayo?

Uma injini ingenzi lutho noma ibanga eliphansi le-rpm (kuye ngokuthi injini ihlanganiswe nosayizi we-turbine), kuba negesi ekhipha umoya eyanele ukuze kuvinjwe i-turbine ekukhiqizeni umfutho we-boost. I-Turbo lag kwenzeka lapho i-gas pedal icindezelwa kanzima kumayunithi e-turbo ejometri engaguquki. Lesi yisikhathi sokungabaza futhi akukho ukusheshisa okungazelelwe. I-turbine enjalo ayikwazi ukusheshisa ngokushesha.

Ukusebenza kwe-geometry turbine eguquguqukayo

I-geometry eguquguqukayo ye-turbine isho ukuthi ngisho nange-rpm ephansi, lapho injini ikhiqiza igesi encane yokukhipha umoya, ukucindezela okusebenzisekayo kungafinyelelwa. I-vacuum valve ihambisa isondo endaweni yokunciphisa ukugeleza kwe-exhaust futhi ikhuphule isivinini sokukhipha umoya. Lokhu kubangela ukujikeleza okusheshayo kwe-rotor nokujikeleza kwesondo lokucindezela ohlangothini olubandayo. Khona-ke ngisho nokucindezela okusheshayo ku-accelerator ngaphandle kokungabaza kuzohumushela ukusheshisa okucacile.

Umklamo we-geometry turbocharger kanye ne-turbocharger evamile

Umshayeli obuka i-turbine ngaphandle angase angawuboni umehluko phakathi kolunye uhlobo nolunye. I-geometry eguquguqukayo ifihliwe ohlangothini olushisayo futhi ngeke ibonakale ngeso. Kodwa-ke, uma ubhekisisa, ungabona ingxenye enkulu kakhulu ye-turbine eduze nendawo yokukhipha umoya. Izilawuli ezengeziwe kufanele zingene ngaphakathi. Kwezinye izinhlobo zama-turbines e-VNT, kukhona nama-valve okulawula umoya we-electro-pneumatic ane-stepper motor eyengeziwe, ebonakala futhi lapho kuhlolwa imishini.

I-Turbine - i-geometry eguquguqukayo kanye nezinzuzo zayo

Enye yezinzuzo zalesi simiso osuvele uyazi ukuthi iqeda umphumela we-turbo lag. Kunezindlela ezimbalwa zokuqeda lesi simo, njengokucebisa ingxube noma ukusebenzisa ama-turbocharger ayi-hybrid. Kodwa-ke, i-geometry ye-turbine eguquguqukayo isebenza kahle kakhulu ezimotweni ezinezinjini ezincane lapho ijika le-torque lidinga ukuphakama ngokushesha okukhulu. Ngaphezu kwalokho, ukuze umgogodla nge-rotor kanye nesondo lokucindezela ukusheshisa, injini ayidingi ukushintshwa ngesivinini esikhulu. Lokhu kubalulekile empilweni yeyunithi, engakhiqiza itorque ephezulu kuma-RPM aphansi.

I-Turbocharger enejometri eguquguqukayo - ukungalungi

Ububi be-variable geometry turbine yilezi:

• ubunkimbinkimbi obukhulu bomklamo wedivayisi ngokwayo. Lokhu kuholela ezindlekweni zokuthenga nokuvuselela kabusha i-turbine enjalo;
• isistimu yokulawula i-vane isengozini yokutheleleka. 

Ukusetshenziswa ngendlela engafanele kwemoto (futhi ngokuyisisekelo injini ngokwayo) ingafinyeza kakhulu impilo ye-turbocharger. Noma yikuphi ukuvuza ohlelweni lokupholisa nokucindezela nakho kuba nomthelela omkhulu ekusebenzeni kwengxenye. Ngenhlanhla, i-geometry eguquguqukayo ivuselelwa futhi ngokuvamile ayidingi ukushintshwa.

Kunzima ukungaboni ukuthi i-geometry eguquguqukayo ye-turbine iwusizo, ozoyithokozela kakhulu lapho ushayela uzungeze idolobha futhi udlula. I-VNT ikuvumela ukuthi unciphise umphumela we-turbo lag ucishe ube ngu-zero. Kodwa-ke, uma kwenzeka ukwehluleka, kunzima kakhulu ukubuyisela amapharamitha okuqala wezinto ezivuselelwe. Nakuba kungadingeki ngaso sonke isikhathi ukushintshwa kufakwe ezintsha, kunzima kakhulu ukukhanda kunezingxenye zendabuko. Ushintsho ekusebenzeni kungase kubonakale, isibonelo uma ubhuleka. Kufanele unqume ukuthi i-geometry eguquguqukayo ingcono yini emotweni yakho kunejometri engaguquki.
