Kuvandudzwa kwekushanda kweinjini dzinopisa mukati zvakakonzera kudzikiswa kwekupisa kwegasi rekubuda. Iko kusungirirwa panguva imwe chete kwemiganhu yekuburitsa simba kunoda zvakanyanya kuomarara nzira dzekudzora kuburitsa, kusanganisiramushure mekurapwaiyo kushanda kwayo kunoenderana zvakanyanya ne tembiricha yekubuda gasi.
Kaviri-madziro epositi akawanda uyeturbine housingma modules akagadzirwa kubva pashizha resimbi akashandiswa mumajini epeturu kubva muna 2009. Vanopa mukana wemazuva ano Diesel injini kuderedza zvose zvinobudiswa zvezvinosvibisa uye kushandiswa kwemafuta. Vanopawo mabhenefiti maererano nehuremu hwechikamu uye tembiricha yepasi pakuenzanisa nesimbi yakakandwa. Zvigumisiro zvinoratidza kuti kushandiswa kwemhepo-gap insulated exhaust systems kunogona kukonzera kuderedzwa kweHC, CO, uye NOx emissions pa tailpipe mu huwandu hwe20 kusvika ku50%, zvichienderana nekugadzirwa kweinjini, kirasi yemotokari inertia, uye kutenderera kwekutyaira, kana ichienzaniswa neyekutanga exhaust system yakarongedzerwa yakajairwa yakakandwa simbi exhaust manifold uye turbine dzimba.
Nekushandiswa kweakagadziridzwa EGR mazano, kuwedzera kweinjini kunze kweNOx mazinga anogona kubvumidzwa nekutora mukana weiyo yepamusoro NOx shanduko muSDPF. Nekuda kweizvozvo, huwandu hwese hwekuchengetedza mafuta hunosvika 2% hwakaonekwa muWLTP uye Kumwe kuvandudzwa kwetekinoroji mumainjini edhiziri kwakakosha kuzadzisa mutemo unoramba uchiomesera wekupeta gasi nekuderedza panguva imwe chete mukubuda kweCO2. MuEU nedzimwe nyika, kuvandudzwa kwemaitiro akatemerwa, akadai seWorldwide harmonised Light cars Test Procedure (WLTP) uye chaiyo yekutyaira emissions (RDE) miganho, ine chokwadi chekuunzwa. Kuunzwa kweaya maitiro akaomesesa kunoda kumwe kuvandudzwa mukushanda kwesystem. Pamusoro peDOC uye dhiziri particulate sefa (DPF), injini dzemangwana dzichange dzakashongedzerwa neNOx mushure mekurapa mudziyo senge NOx yekuchengetera catalyst kana yakasarudzika inogadzirisa yekudzikisa system.
