Catalytic Converter – Explained The purpose of any catalytic converter is to reduce harmful emissions from the exhaust of a "properly tuned" combustion engine. It accomplishes this through a combination of heat and a precious metal catalyst that causes the harmful emissions to either oxidize or reduce to safe elements in the exhaust flow. If the engine is out of tune and not calibrated to OEM specs, the catalytic converter's efficiency is greatly diminished and could lead to a converter failure. The precious metal catalyst is bound to an extruded ceramic honeycomb substrate. The ceramic has hundreds of flow channels that allow the exhaust gasses to come in contact with a maximum amount of surface area where the catalyst reaction takes place. The catalyst must come in direct contact with the exhaust gasses for the reaction to take place. If the ceramic inside your converter becomes clogged or coated with carbon, lead or oil, then the converter’s efficiency is greatly reduced.
