Akungabazeki ukuthi izinga lomoya kanye nokuguquguquka kwesimo sezulu yizona ezihamba phambili emhlabeni wonke. Indlela yokuthuthukisa ukuguquguquka kwe-powertrain ngenkathi kuhlangatshezwana ne-CO2 yesikhathi esizayo kanye nokuhlosiwe kwe-emission kusalokhu kuyinselele futhi kuzodinga izinguquko eziyisisekelo kanye nobuchwepheshe obuthuthukile.
Ngokusekelwe kweminye imibiko yezincwadi ezichwepheshile, nazi amasistimu amabili asetshenziswa kakhulu ama-powertrains propulsion ahlanganayo ukuze kuncishiswe i-CO2 ebonakalayo.
Okokuqala, indlela eyodwa ephumelelayo kodwa elula uma kuqhathaniswa futhi engabizi kakhulu isifakazele ukuthi ebizwa ngokuthi i-Variable Geometry System, (VGS) inganciphisa lokhu kungqubuzana. Ukusebenza kwe-VGS nakho kunomkhawulo njengoba umsebenzi obanzi uyimpoqo. Ukwenyuka kokufakwa kukagesi kwe-powertrain kunamandla amakhulu okuqhubeka nokunciphisa ukungqubuzana phakathi kwezimo eziqinile zesikhashana, ezisezingeni eliphansi kanye nezimfuneko zamandla alinganiselwe enjini. Ukulungiselelwa okwengeziwe kuhloselwe ukuzuza ibhalansi yamandla eqondile iyonke. Kulokhu, ukufaka ugesi kungasetshenziswa ukuthuthukisa ukusebenza kahle kwenjini. Empeleni ziyi-plug kanye nobuchwepheshe bokudlala phezu kokuhlanganiswa kwezimoto. Ngaphezu kwalokho, ahambisana namaturbine ejiyomethri aguquguqukayo kanye nezisombululo zokuphindaphinda kwegesi exhaust futhi ngeke abe umthengi kagesi.
Okwesibili, ukuthuthukiswa kweBrake Specific Fuel Consumption (BSFC) ngezimo zokusebenza ezifanele kanye nokwehliswa okulindelekile kwe-CO2 ku-WLTC. Iphuzu elilodwa elibalulekile lezinhlelo zokushaja ezifakwe ugesi isidingo samandla ngesikhathi somjikelezo. Ukufaka ugesi ku-turbocharger kususa umkhawulo wokudinga i-turbine encane esebenza kahle kakhulu ukushayela iminyaka yayo yesibili yokushajwa kwe-turbo. I-turbocharger enosayizi olungile enjalo ingaletha ukuncishiswa kwe-CO2 ngokusekela ukwehlisa nokwehlisa isivinini ngesikhathi esifanayo.
Ngenxa yalokhu, i-turbocharger kagesi ilinganiswa ukuze i-turbocharger ifakwe injini futhi ibhuleki ukuze ifinyelele futhi ifake isivinini esigcwele se-turbocharger. Kubonisiwe ukuthi i-turbocharger enobukhulu obufanele inganikeza umzila kubakhiqizi bemishini yoqobo ukuhlangabezana nezinselele ezinkulu zobunjiniyela, ikakhulukazi imfuneko yokuhlonipha ukusebenza kwe-stoichiometric, kuyilapho besathuthukisa ukusebenza kwezitimela zabo zikagesi ngokuqhubekayo.
