Hapana mubvunzo kuti hutano hwemhepo uye kushanduka kwemamiriro ekunze ndizvo zvinonyanya kukosha munyika yose.Maitiro ekuvandudza masimba emagetsi uchisangana neremangwana CO2 uye zvinotarwa zvekuburitsa zvinoramba zvichinetsa uye zvinoda shanduko yakakosha uye matekinoroji epamberi.
Kubva pane mamwe marepoti ehunyanzvi, heano maviri anonyanya shandiswa powertrains propulsion masisitimu anosangana kune zvinoonekwa kudzikiswa kweCO2.
Chekutanga, imwe nzira inoshanda asi iri nyore uye isingadhuri yakaratidza kuti inonzi Variable Geometry System, (VGS) inogona kudzikisira kusawirirana uku.Kuita kweVGS kwakaganhurirwawo sezvo kushanda kwakasiyana-siyana kuchisungirwa.Kuwedzera powertrain electrification inotakura mukana mukuru wekuwedzera kudzikisira kupokana pakati penguva pfupi, yakaderera-yekupedzisira-yakagadzikana mamiriro uye yakayerwa simba zvinodiwa zveinjini.Kumwe optimizations kwakanangana nekuwana iyo yakazara yakanaka simba chiyero.Panyaya iyi, magetsi anogona kushandiswa kuvandudza injini kushanda zvakanaka.Iwo akanyanya plug uye yekutamba tekinoroji pamusoro pemotokari hybridization.Zvakare, iwo anowirirana neanosiyana geometry turbines pamwe neanopedza gasi recirculation mhinduro uye haazove mutengi wemagetsi.
Chechipiri, Brake Specific Fuel Consumption (BSFC) kuvandudzwa kwemamiriro ekushanda akakodzera uye kuderedzwa kunotarisirwa kudzikiswa kweCO2 muWLTC.Imwe yakakosha poindi yemagetsi ekuchaja masisitimu ndiko kudiwa kwesimba panguva yekutenderera.Kuisa magetsi turbocharger kunobvisa kumanikidzika kwekuda turbine diki ine hunyanzvi hwekugona kutyaira iyo yechipiri turbocharged age.Yakakwana-saizi yemagetsi turbocharger inogona kuendesa CO2 kuderedzwa nekutsigira kudzikisa uye kudzika nekumhanyisa panguva imwe chete.
Nekuda kweizvozvo, electric turbocharger inoyeverwa kuti turbocharger inogona kufambiswa uye kubhureki kusvika uye kusanganisira yakazara turbocharger kumhanya.Zvave zvichiratidzwa kuti turbocharger yakanyatsogadzirwa nemagetsi inogona kupa nzira yevagadziri vezvigadzirwa zvepakutanga kuti vasangane nemamwe matambudziko makuru einjiniya, kunyanya zvinodiwa kuti varemekedze kushanda kwe stoichiometric, vachiri kuvandudza kushanda kwemagetsi avo.
