Umwikorezi wicyuma cya ternary catalitike ihindura igizwe nigikonoshwa cya silinderi hamwe ninturusu yatunganijwe mugikonoshwa, irangwa nuko intangiriro igizwe nubwinshi bwamasahani yatunganijwe abangikanye kandi aringaniye, kandi isahani yunamye muburyo bwa wavy ni gutondekanya hagati yamasahani abiri yegeranye. Ugereranije n'ikoranabuhanga risanzweho, ibyiza byo gutwara ibyuma bya ternary catalitike ihindura ni ibi bikurikira: Igishushanyo kirumvikana, imiterere iroroshye, ubuzima bwa serivisi ni ndende, igiciro cyo gukora ni gito, akazi gahagaze neza.
Turashobora gutanga ibyuma byombi byubatswe hamwe nibyuma byiza bya Pt, Pd, Rh kandi bidafite ibyuma byiza, kandi dushobora kuzuza ibyuka bihumanya ikirere cya Euro II, Euro III, Euro IV, Euro V, EPA na CARB.
