The exhaust created in the combustion chamber is pushed into the exhaust manifold. The combustion chamber needs to be free of exhaust in order to produce fresh combustion. The exhaust manifold pushes the exhaust into the catalytic converter next so it can be treated before it is released into the environment. After about 100,000 miles, the catalytic converter can get clogged. Here are the problems that are caused by a clogged catalytic converter.
Poor Performance/Economy
If the catalytic converter gets clogged, the exhaust cannot make its way through the converter and through the rest of the exhaust system. Consequently, the engine’s exhaust will back up into the combustion chamber and produce problems with the engine’s combustion. This will reduce your engine’s performance and your vehicle’s fuel economy.
Illuminated Check Engine Warning
You may also end up with an illuminated check engine warning on the dashboard because the exhaust system is malfunctioning. The clock in the catalytic converter will prevent it from being able to treat the exhaust. Consequently, there will be excess carbons in the exhaust that are harmful to the environment. System sensors will pick up on this and report the error to the engine control module.
Dark and Thick Exhaust Smoke
The clog in the catalytic converter can also create dark and thick exhaust smoke that flows out of the tailpipe. As the engine struggles to produce combustion, the engine control module will add fuel to the combustion chamber that is not necessary. Consequently, the engine will burn away the fuel and produce dark exhaust smoke.
Exhaust That Smells Rotten
In addition, your exhaust may start to smell rotten if the catalytic converter is clogged. Unfortunately, this is a sign that there are sulfur deposits throughout the inside of the catalytic converter. These deposits cannot be removed. Once the catalytic converter gets clogged, it needs to be replaced. When they come in contact with hot exhaust, the sulfur deposits release a rotten egg odor.
Excessive Undercarriage Heat
Finally, the catalytic converter is clogged if there is a ton of heat underneath your automobile. You may not realize you have a heat problem until the heat rises into the engine and overheats the engine. Again, replacing the catalytic converter will resolve this issue and restore your engine’s normal operating temperature.
