Kodi turbocharger imagwirizana bwanji ndi kusintha kwanyengo?

Palibe kukayika kuti khalidwe la mpweya ndi kusintha kwa nyengo ndizomwe zimayendetsa dziko lonse lapansi. Momwe mungasinthire mphamvu za powertrain mukakumana ndi CO2 yamtsogolo komanso mipherezero yotulutsa mpweya imakhalabe yovuta ndipo idzafunika kusintha kwakukulu ndi matekinoloje apamwamba.

Kutengera ndi malipoti ena akatswiri a zolemba, nazi njira ziwiri zoyendetsera magetsi zomwe zimagwiritsidwa ntchito kwambiri kuti zichepetse CO2.

Choyamba, njira imodzi yothandiza koma yosavuta komanso yotsika mtengo yatsimikizira kuti yotchedwa Variable Geometry System, (VGS) ingachepetse kusamvanaku. Kuchita kwa VGS kulinso kochepa chifukwa ntchito yamitundu yosiyanasiyana ndiyofunikira. Kuchulukitsa kwa magetsi a powertrain kumakhala ndi kuthekera kwakukulu kochepetsera mkangano pakati pa kwakanthawi, kutsika kokhazikika komanso zofunikira zamphamvu za injini. Kukhathamiritsa kwina ndi cholinga chokwaniritsa mphamvu zonse zabwino. Pachifukwa ichi, magetsi amatha kugwiritsidwa ntchito kuti injini igwire bwino ntchito. Iwo kwenikweni ndi pulagi ndi kusewera luso pamwamba pa hybridization galimoto. Kuphatikiza apo, zimagwirizana ndi ma turbine a geometry osinthika komanso mayankho othamangitsa gasi ndipo sadzakhala ogula magetsi.

Kachiwiri, kukonzanso kwa Brake Specific Fuel Consumption (BSFC) pamikhalidwe yoyenera komanso kuchepetsedwa kwa CO2 mu WLTC. Mfundo imodzi yofunika kwambiri pamakina opangira magetsi ndi kuchuluka kwa mphamvu panthawi yozungulira. Kuyika magetsi pa turbocharger kumachotsa cholepheretsa chofuna turbine yaying'ono yogwira bwino kwambiri kuyendetsa zaka zake zachiwiri zokhala ndi turbocharged. Turbocharger yamagetsi yowoneka bwino yotere imatha kupulumutsa CO2 pothandizira kuchepetsa komanso kutsika mwachangu nthawi yomweyo.

Zotsatira zake, turbocharger yamagetsi imakulitsidwa kuti turbocharger ikhale ndi injini ndikumabuleki mpaka komanso kuphatikiza liwiro lonse la turbocharger. Zasonyezedwa kuti turbocharger yolumikizidwa bwino ingathe kupereka njira kwa opanga zida zoyambirira kuti athe kuthana ndi zovuta zazikulu zauinjiniya, makamaka kufunikira kolemekeza magwiridwe antchito a stoichiometric, pomwe akuwongolerabe magwiridwe antchito amagetsi awo mopitilira.
