Everything you should know about catalytic converters

Catalytic converter. Exhaust system of a modern car bottom view.

Catalytic converters are exhaust emission control components that are often called cats, and they are practically in every automobile on the road. Though they are commonly found, they are hardly ever talked about. Cats are usually used with internal combustion engines and need to work at scorching temperatures to be efficient. They are located underneath the vehicle near the exhaust outlet. And some cars have as many as four of them. 

To help catalytic converters adjust quickly to the temperatures at which they are most effective, they are placed between the engine and muffler. There are different kinds of catalytic converters to fit multiple types of vehicles. However, they all serve the same purpose: to transform toxins and convert them into safer gases such as carbon monoxide and water vapors. 

As mentioned before, catalytic converters are designed to receive exhaust gases and change their chemical makeup. They have a ceramic-based honeycomb structure that is lined with precious metals. These shiny metals aid the catalytic converter in reducing emissions with their chemical reaction. Therefore, an effective cat can ultimately reduce the volume of emissions your car puts out (always a plus).

A catalytic converter contains two sorts of catalysts. The first one uses platinum and rhodium to reduce nitrogen vapors. The second one is an oxidation catalyst that uses platinum and palladium to finish the first catalyst. They both work collectively to reduce what we know as smog. The sensor is the third critical piece of the converter to finish the job.
