Ukuvikelwa kwemvelo kwe-Grvnes kusungule isethi yesistimu yokuphika ye-"grvnes" SCR yokwelapha ama-nitrogen oxides enjinini yomlilo yangaphakathi ngemva kweminyaka yocwaningo olunzima.Ngemuva kokuklama okukhethekile, uhlelo lusakwazi ukubona ukusebenza kahle okuphezulu ngaphansi kwesimo sokushisa okungazinzile kokukhipha kanye nekhwalithi yegesi;Izingxenye ezibalulekile zingamelana nokungcola okuvamile kwegesi yokulahla imfucumfucu futhi ziqinisekise ukusebenza okuzinzile kwesikhathi eside kwesistimu.
