A three-way catalytic converter is a device which uses exhaust heat to oxidize (burn) pollutive emissions, thereby reducing their output into the environment, The term "three-way" refers to the three emissions that three-way converters reduce: 1) carbon monoxide, 2) hydrocarbons and 3) nitrogen oxides. 3, record 1, English, - three%2Dway%20catalytic%20converter

Basically, a catalytic converter is a container of chemically treated pellets ... or a chemically treated honeycomb that is incorporated in the exhaust system. It operates at approximately 1500 deg. F to transform noxious emissions into harmless carbon dioxide and water vapor. 4, record 2, English, - catalytic%20converter

Oxydation du CO [monoxyde de carbone] et des HC [hydrocarbures] dans un seul convertisseur catalytique. Ce genre de catalyseur [...] permet un contrôle strict des HC et du CO, même en travaillant avec des mélanges pauvres [...] 5, record 2, French, - convertisseur%20catalytique

L'épuration catalytique est un procédé [...] [qui] permet de réduire les émissions de CO, HC et NOX, sans modifier la carburation, en agissant directement sur les gaz d'échappement. C'est une technique relativement efficace tant que les catalyseurs que l'on emploie ne sont pas empoisonnés par le plomb (Pb), le soufre (S) et le phosphore (P). En effet, en présence de ces produits la longévité du système d'épuration est sérieusement réduite. 5, record 2, French, - convertisseur%20catalytique
