Osmdes\u00e1t\u00e1 l\u00e9ta 20. stolet\u00ed p\u0159inesla p\u0159evratnou inovaci: t\u0159\u00edcestn\u00fd katalyz\u00e1tor. Na rozd\u00edl od dvoucestn\u00fdch syst\u00e9m\u016f dok\u00e1zaly trojcestn\u00e9 katalyz\u00e1tory sou\u010dasn\u011b redukovat uhlovod\u00edky, oxid uhelnat\u00fd a oxidy dus\u00edku. Toho bylo dosa\u017eeno kombinac\u00ed platiny a palladia pro oxida\u010dn\u00ed reakce s rhodiem pro redukci NOx.

S t\u00edm, jak se emisn\u00ed normy zp\u0159\u00eds\u0148ovaly, se katalyz\u00e1tory vyv\u00edjely.
