The purpose of a catalytic converter is to convert harmful hydrocarbons, carbon monoxide, and nitrogen oxides into harmless compounds. The catalysts inside the catalytic converter convert carbon monoxide and hydrocarbons into carbon dioxide and water, and nitrogen oxides back into nitrogen and oxygen!!!
