Kodi double scroll turbocharger ndi chiyani? [utsogoleri]

Mapangidwe a machitidwe a supercharger amasiyana malinga ndi zosowa za opanga. Chimodzi mwazofunikira zachilendo ndi chikhumbo chofuna kupeza torque yapamwamba pa liwiro lotsika kwambiri, osataya zinthu zamtengo wapatali pa liwiro lalikulu, ndipo ili mu injini ya mafuta. Zingatanthauze kuti injini ya mafuta sadzakhala ndi dzenje lamphamvu ngati injini ya dizilo, koma likupezeka kuti likhoza. Izi zonse ndi chifukwa cha double scroll system.

Mutha kugwiritsa ntchito njira zingapo zowonjezera, incl. ma geometry osinthika kapena ma twin-turbo ndi bi-turbo system, koma munjira iliyonse pali vuto lomwe mpweya wotulutsa kuchokera ku masilindala amodzi samalowa mu turbine rotor nthawi imodzi komanso mofanana, koma m'njira yopumira komanso yosasinthika. Zotsatira zake, amasokonezana wina ndi mzake pakhomo la nyumba ya turbine ndipo sagwiritsa ntchito mphamvu zawo zonse.

Choncho twin-scroll turbocharged solution yomwe imagawaniza zotulutsa munjira ziwiri (yosonyezedwa mu zofiira), imodzi yomwe imatumikira, mwachitsanzo, mu injini ya 4-cylinder, ma cylinders akunja, ndi enawo, ma silinda amkati. Izi zimapewa kusokoneza kuyenda mpaka ku nyumba ya turbine. Palinso njira ziwiri pano, koma pali chipinda chimodzi kutsogolo kwa rotor (chowonetsedwa mu buluu). Posankha kutalika koyenera ndi kuchuluka kwa madoko olowera, mutha kugwiritsa ntchito zochitika zamafunde zomwe zimayenderana ndi kusuntha kwa injini, komanso kugwiritsa ntchito bwino mphamvu ya mpweya wotulutsa mpweya. Chifukwa cha kugawanika kwa nyumba za turbine, zosokoneza zosafunikira sizimapangidwa pa liwiro lotsika, ndipo turbocharger yaing'ono imayankha mofulumira kwambiri kukanikiza gasi pedal.

Pazojambula zotere, palibe chifukwa chosinthira ma turbine geometry.zomwe sizimagwiritsidwa ntchito kawirikawiri mu injini zamafuta. Ndipo komabe mbali yaikulu ya mapasa-mpukutu turbocharged injini ndi mofulumira kwambiri kuchita ndi Kuwonjezera wa gasi. Zitha kunenedwa kuti mtundu uwu wa turbocharger umathetsa zochitika za turbolag.

Mmodzi mwa omwe adayambitsa kugwiritsa ntchito ma twin-scroll turbo system ndi BMW. yomwe imagwiritsa ntchito mawu akuti Twin Power Turbo pamayunitsi ake. Ndizofunikira kudziwa kuti palibe chomwe chimalepheretsa kugwiritsa ntchito ma turbocharger amapasa pama injini amapasa awiri monga V8s. Chitsanzo china ndi Ford, yomwe idagwiritsa ntchito turbocharger yamapasa pamasewera a Focus RS. Omwe adayendetsa galimotoyi amadziwa momwe injini yake imachitira mwachangu pakuwonjezedwa kwa gasi komanso momwe ilili yamphamvu pamayendedwe aliwonse. Ndikokwanira kunena kuti 2,3-lita petulo wagawo akufotokozera 440 Nm mu osiyanasiyana kuchokera 2000 kuti 4500 rpm. Kampani ina yomwe yagwiritsa ntchito mapasa-scroll turbocharger ndi Lexus. Mu NX, ndi 2-lita petulo injini.
