Iinjini zokutsha zangaphakathi zikhupha izixa ezikhulu zenitrogen oxides.Itekhnoloji yokuNcitshiswa kwe-Selective Catalytic (SCR) yeyona inamandla kuwo onke amanyathelo okunciphisa i-nitrogen oxides kwaye inokunciphisa ukukhutshwa kumanqanaba aphantsi kakhulu.Ngenxa yale njongo, i-liquid eyongezelelweyo (i-AdBlue) ifakwe kumgca wokukhupha emva kwe-turbocharger kunye ne-vaporises endleleni eya kwi-catalyst.Apho, i-AdBlue iguqula i-nitrogen oxides kwi-catalyst kwi-nitrogen kunye namanzi, zombini izinto zendalo kunye nezingezona ityhefu ngokupheleleyo.Isixa esilinganisiweyo se-AdBlue kunye nokuhanjiswa kwayo ngaphezulu kwe-catalyst imisela ukusebenza kakuhle kwenkqubo ngokuqinisekileyo.
I-GRVNES inikezela ngezisombululo ezahlukeneyo ezilungiselelwe usetyenziso oluthile.Njengomvelisi kunye nomthengisi wenkqubo yonke yokukhupha, abathengi bayazuza kwisiphumo esiqwalasela ukukhutshwa ngokupheleleyo kwaye unikeze isisombululo esenziwe ngokufanelekileyo esilungiselelwe ngokufanelekileyo kwiimfuno.
