A catalytic converter is a device that reduces the pollutants in exhaust gases from an internal combustion engine. It does this by converting harmful gases, such as carbon monoxide and nitrogen oxides, into less harmful substances, such as carbon dioxide and nitrogen. Catalytic converters are an important part of reducing air pollution and are required by law in many countries.
However, catalytic converters can sometimes become clogged or damaged, which can reduce their effectiveness or cause them to fail. If a catalytic converter fails, it can lead to increased emissions and decreased engine performance. In some cases, a failed catalytic converter can even cause the engine to stall.
