Zvimiro zveTwinTurbo turbocharging system

Dambudziko guru pakushandisa turbocharger ndeye inertia yehurongwa kana kuitika kweiyo inonzi "turbo lag" (nguva yepakati pakati pekuwedzera kweinjini yekumhanya uye kuwedzera kwesimba kwesimba). Kuibvisa, chirongwa chakagadzirwa pachishandiswa maturbocharger maviri, ayo ainzi TwinTurbo. Iyi tekinoroji inozivikanwa zvakare seBiTurbo nevamwe vagadziri, asi dhizaini mutsauko uri muzita rekutengesa chete.

Twin Turbo Features

Dual compressor masisitimu anowanikwa edhiziri uye peturu injini. Zvisinei, iyo yekupedzisira inoda kushandiswa kwepamusoro pehuni ine nhamba yakakwirira yeoctane, iyo inoderedza mukana wekuputika (chinhu chisina kunaka chinoitika mumagetsi ejini, kuparadza boka re-cylinder-piston).

Pamusoro pebasa rayo rekutanga rekudzikisa turbo lag nguva, iyo Twin Turbo scheme inobvumira simba rakawanda kutorwa kubva muinjini yemotokari, inoderedza kushandiswa kwemafuta uye inochengetedza peak torque pamusoro peyakakura rev rev. Izvi zvinowanikwa nekushandisa akasiyana compressor ekubatanidza zvirongwa.

Mhando dzeTurbocharging dzine maturbocharger maviri

Zvichienderana nekuti ma turbocharger akabatana sei, pane matatu akakosha marongero eiyo TwinTurbo system:

• parallel;
• inopindirana;
• akatsika.

Kubatanidza turbines mukufanana

Inopa kubatana kwema turbocharger maviri akafanana anoshanda akafanana (panguva imwe chete). Chinokosha chekugadzira ndechekuti maturbine maviri madiki ane inertia shoma pane yakakura.

Usati wapinda mumasilinda, mhepo inoputirwa nezvose zviri zviviri turbocharger inopinda muhuwandu hwekutora, iyo inosanganiswa nemafuta uye inogoverwa kumakamuri ekupisa. Ichi chirongwa chinowanzoshandiswa painjini dzedhiziri.

Serial connection

Iyo yakatevedzana-parallel scheme inopa kuisirwa kwematurbine maviri akafanana. Imwe inoshanda nguva dzose, uye yechipiri yakabatana nekuwedzera kweinjini kumhanya, kuwedzera kwemutoro, kana mamwe maitiro anokosha. Kuchinja kubva kune imwe nzira yekushandisa kuenda kune imwe kunoitika kuburikidza nevharuvhu inodzorwa neinjini yemotokari ECU.

Iyi sisitimu yakanangana nekubvisa turbo lag uye kuwana yakatsetseka yekumhanyisa dynamics yemota. TripleTurbo masisitimu anoshanda zvakafanana.

Nhanho chirongwa

Maviri-nhanho supercharging ine maviri turbocharger ehukuru hwakasiyana, akaiswa munhevedzano uye akabatana kune ekutora uye exhaust ports. Iwo ekupedzisira ane mavharuvhu ebypass anogadzirisa mafambiro emhepo uye exhaust gasi. Nhanho yedunhu ine nzira nhatu dzekushanda:

• Mavharuvhu akavharwa pa low rpm. Exhaust magasi anopfuura nematurbine ese ari maviri. Nekuda kwekuti gasi radzikira, ma impeller makuru eturbine haatenderere. Mhepo inoyerera nepamatanho ese ari maviri compressor zvichikonzera kushomeka kwakanyanya.
• Sezvo RPM inowedzera, vheji yekupedza inotanga kuvhura, iyo inotyaira turbine huru. Iyo compressor yakakura inomanikidza mhepo, mushure meiyo inotumirwa kune vhiri diki, uko kunowedzera kudzvanywa kunoshandiswa.
• Kana injini ichimhanya nekumhanya kwakazara, mavharuvhu ese ari maviri akazaruka, ayo anotungamira kuyerera kwemagasi emhepo akananga kune yakakura turbine, mhepo inopfuura nemucompressor hombe uye pakarepo inotumirwa kumasilinda ejini.

Iyo stepped version inonyanya kushandiswa kumotokari dzedhiziri.

Twin Turbo zvakanakira uye zvakaipira

Parizvino, TwinTurbo inonyanya kuisirwa pamotokari dzepamusoro-soro. Iko kushandiswa kweiyi sisitimu kunopa zvakanakira sekufambiswa kweiyo torque yakakura pamusoro pehupamhi hwekumhanya kweinjini. Mukuwedzera, nekuda kweiyo mbiri turbocharger, ine zvishoma zvishoma kushanda kwevhoriyamu yesimba remagetsi, kuwedzera kwesimba kunowanikwa, izvo zvinoita kuti ive yakachipa kupfuura iyo "inoshuvira".

Izvo zvakanyanya kuipa kweBiTurbo ndeyekudhura kwakanyanya, nekuda kwekuoma kwechigadzirwa. Sezvinoita turbine yekare, maviri maturbocharger masisitimu anoda kubata kwakapfava, mafuta ari nani uye kuchinja kweoiri panguva.
