    Catalyst

    Well dispersed precious metal and/or transition metal coated on ceramic honeycomb structure

    Converter

    High quality stainless steel canister

    DPF

    Three Way Catalyst

    Three-way catalyst is made of ceramic honeycomb substrate coated with precious metals. This catalyst converts HC, CO, Nox emitted from gasoline vehicles into CO2, H2o and N2

    Performance

    Diesel Oxidation Catalyst

    DOC is made of ceramic honeycomb substrate coated with precious metals. DOC efficiently reduces HC, CO, Soluble Organic Fraction from diesel exhaust emissions
