Likarolo tsa sistimi ea TwinTurbo turbocharging

Bothata bo ka sehloohong ha u sebelisa turbocharger ke inertia ea tsamaiso kapa ketsahalo ea seo ho thoeng ke "turbo lag" (nako ea nako pakeng tsa ho eketseha ha lebelo la enjene le ho eketseha ha sebele ha matla). Ho e felisa, ho ile ha qaptjoa leano le sebelisang li-turbocharger tse peli, tse neng li bitsoa TwinTurbo. Theknoloji ena e boetse e tsejoa e le BiTurbo ke bahlahisi ba bang, empa phapang ea moralo e ka lebitso la khoebo feela.

Likarolo tsa Twin Turbo

Litsamaiso tse peli tsa compressor li teng bakeng sa lienjine tsa diesel le peterole. Leha ho le joalo, ho qetela ho hloka tšebeliso ea mafura a boleng bo phahameng ka palo e phahameng ea octane, e fokotsang monyetla oa ho phatloha (ntho e mpe e hlahang ka har'a li-cylinders tsa enjene, e senyang sehlopha sa cylinder-piston).

Ntle le ts'ebetso ea eona ea mantlha ea ho fokotsa nako ea turbo lag, leano la Twin Turbo le lumella matla a mangata hore a huloe enjene ea koloi, e fokotsa tšebeliso ea mafura le ho boloka torque ea tlhoro holim'a mefuta e mengata e fapaneng. Sena se finyelloa ka ho sebelisa mekhoa e fapaneng ea khokahano ea compressor.

Mefuta ea turbocharging e nang le li-turbocharger tse peli

Ho latela hore na li-turbocharger li hokahane joang, ho na le meralo e meraro ea mantlha ea sistimi ea TwinTurbo:

• tšoanang;
• feto-fetoha;
• hata.

Ho kopanya li-turbines ka ho lekana

E fana ka khokahanyo ea li-turbocharger tse peli tse tšoanang tse sebetsang ka nako e le 'ngoe (ka nako e le' ngoe). Moko oa moralo ke hore li-turbine tse peli tse nyane li na le inertia e nyane ho feta e kholo.

Pele o kena ka har'a li-cylinders, moea o pompetsoeng ke li-turbocharger ka bobeli o kena ka bongata bo kenang, moo o kopanyang le mafura 'me o abeloa likamoreng tse tukang. Morero ona o sebelisoa hangata lienjineng tsa disele.

Khokahano ea serial

Potoloho ea letoto-parallel e fana ka ho kenngoa ha li-turbine tse peli tse tšoanang. E 'ngoe e sebetsa kamehla,' me ea bobeli e amana le ho eketseha ha lebelo la enjene, ho eketseha ha mojaro, kapa mekhoa e meng e khethehileng. Ho tloha ho mokhoa o mong oa ho sebetsa ho ea ho o mong ho etsahala ka valve e laoloang ke enjene ea koloi ECU.

Sistimi ena e ikemiselitse haholo ho felisa turbo lag le ho fihlela matla a ho potlakisa koloi. Sistimi ea TripleTurbo e sebetsa ka mokhoa o ts'oanang.

Morero oa mehato

Supercharging ea mekhahlelo e 'meli e na le li-turbocharger tse peli tsa boholo bo fapaneng, tse kentsoeng ka letoto mme li hokahane le likou tsa ho kena le tsa ho tsoa. Tse latelang li na le li-valve tsa bypass tse laolang ho phalla ha moea le likhase tsa mouoane. Potoloho ea mehato e na le mekhoa e meraro ea ts'ebetso:

• Li-valve li koetsoe ka rpm e tlase. Likhase tsa mouoane li feta har'a li-turbine tse peli. Ka lebaka la khatello ea khase e tlase, li-impellers tse kholo tsa turbine ha li khone ho potoloha. Moea o phalla ka mekhahlelo e 'meli ea compressor e bakang khatello e nyane haholo.
• Ha RPM e ntse e eketseha, valve ea ho tima e qala ho buleha, e tsamaisang turbine e kholo. Compressor e kholoanyane e hatella moea, ka mor'a moo e romeloa lebiling le lenyenyane, moo khatello e eketsehileng e sebelisoang.
• Ha enjene e sebetsa ka lebelo le feletseng, li-valve ka bobeli li bulehile ka ho feletseng, tse tsamaisang phallo ea likhase tsa ho qeta ka ho toba ho turbine e kholo, moea o feta ka har'a compressor e kholo 'me hang-hang o romelloa ho li-cylinders tsa enjene.

Mofuta oa stepped o sebelisoa haholo bakeng sa likoloi tsa diesel.

Melemo le boiketlo ba Twin Turbo

Hajoale, TwinTurbo e kentsoe haholo likoloing tse sebetsang hantle haholo. Tšebeliso ea tsamaiso ena e fana ka melemo e kang phetisetso ea torque e phahameng ho feta mefuta e mengata ea lebelo la enjene. Ho phaella moo, ka lebaka la li-turbocharger tse peli, tse nang le palo e nyenyane ea ho sebetsa ea matla a matla, ho eketseha ha matla ho finyelloa, e leng se etsang hore e theko e tlaase ho feta "aspirated".

Litsietsi tse ka sehloohong tsa BiTurbo ke litšenyehelo tse phahameng, ka lebaka la ho rarahana ha sesebelisoa. Joalo ka turbine ea khale, li-turbocharger tse peli li hloka ho ts'oaroa ha bonolo, mafura a betere le liphetoho tsa oli tse nakong.
