Yes, the catalytic converter does affect engine performance. We will explain this in greater detail below. The bottom line is that there will come a time when the catalytic converter needs to be replaced if you drive an older automobile. Willoughby Hills Auto Repair explains that the average lifespan of the catalytic converter is 10 years. After that time, you may notice the following signs that the catalytic converter is malfunctioning. This malfunction can be due to age or to a clog.
Acceleration/Engine Lag
How the catalytic converter affects your engine performance is that it reduces it. When the catalytic converter is malfunctioning, it will often push the engine exhaust back into the combustion chamber. The exhaust is cleared out of the chamber because there needs to be room for fresh air and fuel. If the exhaust is clogging the chamber, your vehicle’s acceleration and engine performance will lag. This is primarily caused by a clog in the catalytic converter.
Black Engine Exhaust Smoke
The catalytic converter is responsible for treating your engine’s exhaust before it flows out of the tailpipe. Specifically, it converts dangerous emissions into safer ones. If the converter is not doing its job, you may end up with black exhaust smoke flowing out of the tailpipe. This is an indication that the exhaust has not been treated properly before it is being released. This can cause problems with your vehicle’s emissions levels as well as open you up to carbon monoxide poisoning.
Heat Underneath the Vehicle
The catalytic converter can also overheat when it is malfunctioning and this will create excessive heat underneath your car, truck, or utility vehicle. Unfortunately, you may end up with your engine overheating, as well, if the catalytic converter’s heat rises into the engine. If your engine has been running hot recently, check for hot odors emitting from underneath the vehicle, as well. This is where the catalytic converter is located.
Rotten Egg Exhaust Odors
Finally, a faulty catalytic converter will release a very distinctive odor: rotten eggs. You will detect this odor in your vehicle’s exhaust. This odor may also waft into the engine leaving you to smell it in the engine bay, as well. This is definitely a sign that there is a problem with the catalytic converter. The only other time you would smell rotten eggs is if your battery is leaking acid.
