As it looks exactly like the muffler externally, inside is a core of ceramic beads enclosed in pores that happen to be coated with certain catalysts. Included in this are palladium, platinum and rhodium. Platinum is definitely an oxidation catalyst, rhodium can be a reduction catalyst and palladium does both.

What makes it work?

The catalytic converter functions reduce the emission of harmful gases such as carbon monoxide, nitrogen oxides and hydrocarbons. Each of the gases in the engine go through the converter as well as the muffler. While they pass through the ceramic beads a compound reaction occurs which changes the gases into water vapour and other harmless gases. The oxidation catalysts convert the co and hydrocarbons into carbon dioxide and water, while the reduction catalysts convert nitrogen oxide into its constituent aspects of nitrogen and oxygen.

Just how do they go wrong?

Catalytic converters can become clogged, but checking this is difficult for your car repair technician. It will will have being removed to find out if the engine’s performance then improves; whether or not this does then a it is blocked.
