Most modern catalysts contain such precious metals, as platinum, palladium, and rhodium. Such devices can be easily found in many countries of the world. German and British manufacturers often use iridium too. In many cases, catalysts manufactured in these two countries are sorted separately as potentially containing this precious metal.
The content of platinum in Japanese and Chinese cars is 15 % lower than in European ones. European catalysts contain twice as much precious metals as American devices. That is why converters from the USA are cheaper.
It is no wonder that a catalyst is one of the most expensive car parts, but it is truly useful. As it is widely known, this device is essential for removing toxic pollutants and contaminants from exhaust gases and making them non-hazardous for the environment and health of people. But looking for a reliable cat at a reasonable price sometimes turns into a difficult quest. If you have faced such problems and do not want to have the same bitter experience, we suggest you pay attention to the online store https://autocatalystmarket.com/us/en. Here you can select a good device for any car brand.
How a Catalyst Works
A catalyst neutralizes a wide range of toxic compounds, such as CO (carbon monoxide), CH (hydrocarbons), NO, NO2 (nitrogen oxides). These and some other contaminants make up smog and affect the environmental situation.
Using a catalytic converter helps a lot to change the situation for the better. The precious metals contained in this device go into a chemical reaction with toxic combustion products and clean up exhaust gases by turning them into neutral compounds.
There is a ceramic or metal honeycomb-like element inside the converter housing with a layer of precious metals. It is required to increase the contact area of exhaust gases with the surface on which the catalytic layer is applied. Due to chemical oxidation reaction instead of CO and CH a catalyst releases just CO2 and N2.
But remember that you need to monitor the current condition of your catalyst for many reasons. A clogged or failed converter is not just useless, it is dangerous for the engine of your vehicle. If there are some problems with the catalyst, you can notice some negative changes in the operation of your car. The most common symptoms are engine power loss and lighting up of the check engine lamp. To be sure about your catalyst use a reliable device and have it regularly maintained.
