    Types of Catalytic Converters on the Road Today

    Understanding what type of converter your vehicle uses helps clarify total replacement costs and emission compliance requirements in Colorado:

    2-WAY

    Two-Way Catalytic Converters

    Common on older vehicles, two-way converters break down two types of emissions: Hydrocarbons (HC) and Carbon Monoxide (CO). After passing through, these are released as carbon dioxide ($CO_2$) and water ($H_2O$).

    Most Common
    3-WAY

    Three-Way Catalytic Converters

    Newer cars feature these components, which deal with Nitrogen Oxide (NO) in addition to HC and CO. The conversion releases $CO_2$, $H_2O$, nitrogen ($N_2$), and oxygen ($O_2$).

    DOC

    Diesel Oxidation Catalysts (DOC)

    Like two-ways, converters for diesel engines break down HC and CO. They can process NO — but not quite as effectively as three-way converters can.
