Imephu entsha isekwe kusetyenziso lweeparamitha zolondolozo njengamandla e-turbocharger kunye nokuhamba kobunzima beiturbine ukuchaza ukusebenza kweinjini yeinjini kuzo zonke iindawo zeVGT. Iigophe ezifunyenweyo zifakwe ngokuchanekileyo kunye neepolynomials ze-quadratic kunye neendlela ezilula zokudibanisa zinika iziphumo ezithembekileyo.
Ukuhla kuyindlela yokuphuhlisa injini evumela ukusebenza kakuhle kunye nokukhutshwa okuphantsi okusekwe ekwandeni kwemveliso yamandla kwiinjini ezincitshisiweyo zokufuduswa. Ukuze ufezekise le mveliso ephezulu kuyimfuneko ukwandisa uxinzelelo lokunyusa. Kule minyaka ilishumi idlulileyo, itekhnoloji yejiyometri ye-turbocharger (VGT) eguquguqukayo isasazeke kuzo zonke ii-injini zokufuduswa kunye nawo onke amacandelo entengiso, kwaye kule mihla, itekhnoloji entsha yokutshaja i-turbocharging iye yavavanywa njengee-compressor zejometri eziguquguqukayo, ii-injini ze-turbocharged ngokulandelelana okanye iinjini ezixineneyo.
Uyilo oluchanekileyo kunye nokudibanisa inkqubo ye-turbocharging kwi-injini yokutshisa yangaphakathi ibaluleke kakhulu ekuziphatheni okuchanekileyo kwe-injini yonke. Ngokuthe ngqo, ibalulekile kwinkqubo yotshintshiselwano lwerhasi kunye nangexesha le-injini yenguquko yexeshana, kwaye iya kuba nefuthe ngendlela ebalulekileyo ekusetyenzisweni okuthe ngqo kwe-injini kunye nokukhutshwa kongcoliseko.
Iimpawu ze turbine zifakwe ngokuchanekileyo imisebenzi ye-polynomial ye-quadratic. Le misebenzi inomdla wokuba yahlulwe ngokuqhubekayo kwaye ngaphandle kokuyeka. Umahluko phakathi kokuziphatha kweeinjini zomoya ezizinzileyo okanye phantsi kweemeko zokuqukuqela okuguquguqukayo, kunye neziganeko zokhutshelo lobushushu kwi-injini yomoya zisephantsi kophando. Kule mihla, asikho isisombululo esilula sokusombulula ezi ngxaki kwiikhowudi ze-0D. Umelo olutsha lusebenzisa iiparamitha ezigcinayo ezingenovakalelo kangako kwiziphumo zazo. Ngoko ke iziphumo ezixutyiweyo zithembeke ngakumbi kwaye ukuchaneka kwayo yonke injini yokulinganisa iyaphuculwa.
