3-Way Catalytic Converter System


The 3-way catalytic converter functions to reduce nitrogen oxides and oxidizes hydrocarbons and carbon monoxide.

The converter is mounted directly to the exhaust manifold. The converter unit houses a "honeycomb" type catalyst with bonding material inside a cast iron casing. A ceramic type seal is employed to prevent exhaust leakage between the case and the outer wall of the catalyst.
