Catalytic converter (colloquially, “cat” or “catcon”)

A device used to reduce the toxicity of emissions from an internal combustion engine.

Working Principle of Three-way Catalytic converter:

Reduction of nitrogen oxides to nitrogen and oxygen:

2NO_x → xO₂ + N₂

Oxidation of carbon monoxide to carbon dioxide:

2CO + O₂ → 2CO₂

Oxidation of un-burnt hydrocarbons (HC) to carbon dioxide and water:

C_xH_2x+2 + [(3x+1)/2]O₂ → xCO₂ + (x+1)H₂O
