Izici ze-TwinTurbo turbocharging system

Inkinga enkulu uma usebenzisa i-turbocharger yi-inertia yesistimu noma ukuvela kwalokho okubizwa ngokuthi "i-turbo lag" (isikhathi sokuphumula phakathi kokunyuka kwejubane lenjini kanye nokwanda kwangempela kwamandla). Ukuyiqeda, kwasungulwa uhlelo kusetshenziswa ama-turbocharger amabili, ayebizwa nge-TwinTurbo. Lobu buchwepheshe baziwa nangokuthi i-BiTurbo ngabanye abakhiqizi, kodwa umehluko wokuklama usegameni lokuhweba kuphela.

Izici ze-Twin Turbo

Amasistimu ama-compressor amabili ayatholakala ezinjini zikadizili nekaphethiloli. Nokho, lokhu kwakamuva kudinga ukusetshenziswa uphethiloli izinga okusezingeni eliphezulu nge octane inombolo ephezulu, okunciphisa amathuba detonation (into engeyinhle eyenzeka amasilinda injini, ecekela phansi isilinda-piston iqembu).

Ngaphezu komsebenzi wayo oyinhloko wokunciphisa isikhathi se-turbo lag, i-Twin Turbo scheme ivumela amandla engeziwe ukuthi idonswe enjini yemoto, inciphisa ukusetshenziswa kukaphethiloli futhi igcine i-torque ephezulu ngaphezu kwebanga elibanzi lokuvuselela. Lokhu kufezwa ngokusebenzisa izikimu zokuxhuma ze-compressor ezahlukahlukene.

Izinhlobo ze-Turbocharging ezinama-turbocharger amabili

Kuya ngokuthi ama-turbocharger axhumeke kanjani, kunezakhiwo ezintathu eziyisisekelo zohlelo lwe-TwinTurbo:

• ukufana;
• kuyavumelana;
• wanyathela.

Ukuxhuma ama-turbines ngokuhambisana

Ihlinzeka ngoxhumo lwama-turbocharger amabili afanayo asebenza ngokufana (ngasikhathi sinye). Ingqikithi yomklamo ukuthi izinjini zomoya ezimbili ezincane zine-inetia encane kunenkulu.

Ngaphambi kokungena kumasilinda, umoya ophonswa yiwo womabili ama-turbocharger ungena endaweni eningi yokuthatha, lapho uhlangana khona nophethiloli bese usakazwa emakamelweni avuthayo. Lolu hlelo lusetshenziswa kakhulu ezinjinini zikadizili.

uxhumano lwe-serial

Isekethe ye-series-parallel ihlinzeka ngokufakwa kwama-turbine amabili afanayo. Omunye usebenza njalo, kanti owesibili uxhunywe nokwanda kwejubane lenjini, ukwanda komthwalo, noma ezinye izindlela ezikhethekile. Ukushintsha usuka kwenye imodi yokusebenza uye kwenye kwenzeka ngevalvu elawulwa injini yemoto i-ECU.

Lolu hlelo luhloselwe ngokuyinhloko ukuqeda i-turbo lag kanye nokufeza ukusheshisa okushelelayo kwemoto. Amasistimu e-TripleTurbo asebenza ngokufanayo.

Isikimu sezinyathelo

I-supercharging enezigaba ezimbili iqukethe ama-turbocharger amabili anosayizi abahlukene, afakwe kuchungechunge futhi axhunywe kumachweba okungenisa nawokukhipha. Lezi zamuva zifakwe ama-bypass valves alawula ukugeleza komoya namagesi akhipha umoya. I-step circuit inezinhlobo ezintathu zokusebenza:

• Amavalvu avaliwe nge-rpm ephansi. Amagesi e-exhaust adlula kuwo womabili ama-turbines. Ngenxa yokuthi umfutho wegesi uphansi, ama-impeller amakhulu aphehla ugesi awajikelezi. Umoya ugeleza kuzo zombili izigaba ze-compressor okuholela ekucindezelekeni okuncane kakhulu.
• Njengoba i-RPM ikhula, i-valve yokukhipha iqala ukuvuleka, eshayela i-turbine enkulu. I-compressor enkulu icindezela umoya, emva kwalokho ithunyelwa esondweni elincane, lapho ukucindezela okwengeziwe kufakwa khona.
• Lapho injini isebenza ngesivinini esigcwele, ama-valve womabili avuleka ngokugcwele, aqondisa ukugeleza kwamagesi e-exhaust ngqo ku-turbine enkulu, umoya udlula ku-compressor enkulu futhi ngokushesha uthunyelwe kumasilinda enjini.

Inguqulo enezinyathelo isetshenziswa kakhulu ezimotweni zikadizili.

I-Twin Turbo okuhle nokubi

Njengamanje, i-TwinTurbo ifakwe ikakhulukazi ezimotweni ezisebenza kahle kakhulu. Ukusetshenziswa kwalesi simiso kunikeza izinzuzo ezifana nokudluliswa kwe-torque enkulu phezu kwejubane elibanzi lenjini. Ngaphezu kwalokho, ngenxa ye-turbocharger emibili, enevolumu encane yokusebenza yeyunithi yamandla, ukwanda kwamandla kufinyelelwa, okwenza kube ishibhile kune "aspirated".

Ukungalungi okuyinhloko kwe-BiTurbo yizindleko eziphezulu, ngenxa yobunzima bedivayisi. Njenge-turbine yakudala, amasistimu e-turbocharger adinga ukuphathwa okuthambile, uphethiloli ongcono kanye nezinguquko zikawoyela ezifika ngesikhathi.
