VTG - Yosinthika Geometry Turbocharger
Mfundo ya ntchito ya turbocharger anatulukira zaka 100 zapitazo. Pokhapokha mu nthawi yathu chipangizo ichi akukumana ndi kubwezeretsedwa mu kutchuka.

Imodzi mwa njira zosavuta kuonjezera mphamvu injini ndi supercharging, ndiye kukakamiza mpweya mu masilindala ake. Mwa mitundu yosiyanasiyana ya compressor, yotchuka kwambiri ndi turbocharger, yomwe nthawi zambiri imaphatikizidwa ndi injini ya dizilo.
Turbocharger imakhala ndi ma rotor awiri omwe ali pamtunda womwewo. Kuzungulira kwa rotor, motsogozedwa ndi mphamvu ya mpweya wotuluka kuchokera mu injini, kumapangitsa kuti rotor yachiwiri ikhale yozungulira nthawi imodzi, zomwe zimakakamiza mpweya kulowa mu injini. Chifukwa chake, palibe gwero lamphamvu lowonjezera lomwe limafunikira kuyendetsa turbocharger.
Mu injini iliyonse ya pisitoni, pafupifupi 70% ya mphamvu zomwe zimapezedwa chifukwa cha kuyaka kwamafuta zimatulutsidwa mopanda phindu mumlengalenga limodzi ndi mpweya wotulutsa mpweya. Turbocharger osati bwino ntchito ya injini, komanso kumawonjezera dzuwa lake.
Tsoka ilo, monga momwe zimakhalira muukadaulo, palibe mapangidwe abwino, kotero turbocharger yapamwamba imakhala ndi zovuta zake. Choyamba, ilibe kuthekera kwa kusintha "kosalala" pakukakamiza kowonjezera kwa masilinda ndipo imadziwika ndi kuchedwa pakuyankha kukanikiza chopondapo cha gasi. Zili mu mfundo yakuti mphamvu ya injini sikuwonjezeka mwamsanga pambuyo atolankhani mwamsanga pa accelerator pedal. Pokhapokha pakapita kanthawi injiniyo imathamanga mofulumira. Zolakwika izi zidawoneka makamaka pamainjini a dizilo a njanji. Umu ndi momwe turbocharger ya VTG yokhala ndi turbine geometry idapangidwira.
Zimagwira ntchito posintha mawonekedwe a masamba a turbine, kuti ntchito ya turbocharger ndiyothandiza kwambiri ngakhale pa injini yotsika komanso yotsika kwambiri. Kuphatikiza apo, zidakhala zotheka kusintha bwino kuthamanga kwamphamvu.
Mu injini za dizilo za VTG, palibe ntchito yowoneka bwino, ndipo ma torque ndi okwera ngakhale pa liwiro lotsika kwambiri la injini, komanso mphamvu yawonjezeka.
