Platinum is an oxidation catalyst, rhodium is a reduction driver as well as palladium does both.
How does it work?
The catalytic converter functions to reduce the discharge of unsafe gases such as carbon monoxide, nitrogen oxides and also hydrocarbons. All the gases from the engine pass through the converter as well as the muffler. As they pass throughout the ceramic grains a chain reaction happens which alters the gases right into water vapour and other safe gases. The oxidation drivers convert the carbon monoxide and hydrocarbons right into carbon dioxide and water, while the decrease drivers convert nitrogen oxide right into its component parts of nitrogen and also oxygen.
Just how do they fail?
Catalytic converters can end up being clogged, however examining this is tough for your cars and truck repair work professional.
