What are the methods to deal with excessive carbon monoxide in car exhaust?

Clean the three-way catalytic converter. Once this component is clogged or too dirty, it will lose its ability to convert carbon monoxide. Check the dashboard for any engine warning lights. If the air-fuel ratio of the engine cannot stabilize, incomplete combustion may occur.
I've been driving trucks for over twenty years and encountered excessive carbon monoxide levels several times, usually due to overly rich engine fuel mixture or aging systems. When dealing with it, I start with simple checks, like cleaning the air filter to see if it's clogged, which can prevent insufficient air intake leading to incomplete combustion. The oxygen sensor often gives trouble, so I frequently replace it myself with a new one to test. Also, if the spark plugs misfire, I check the ignition coils for cracks or oxidation. If the catalytic converter is broken, the vehicle inspection will definitely fail, so it needs timely replacement. Don’t slack on regular maintenance—use good fuel additives to reduce carbon buildup and test exhaust concentration periodically. Once, at a repair shop, I found a leak in the three-way catalytic converter. After spending a few hundred bucks to fix it, emissions returned to normal. Safe driving really comes down to paying attention to these small details.
As an ordinary car owner, I am particularly concerned about the safety hazards of vehicle emissions. Carbon monoxide exceeding standards cannot be ignored, and the key solution is to thoroughly inspect the engine's working condition. Start from the source by checking if the fuel injectors are dirty or clogged—cleaning them can improve fuel injection precision. Unstable signals from the oxygen sensor can also cause an overly rich fuel mixture, so keep a spare one in the car. Additionally, inspect the intake manifold for leaks by brushing soapy water around the connections to check for bubbles. Pay attention to the fuel pump pressure as well, as excessively high pressure can lead to exhaust issues. I recommend immediately visiting a professional workshop for an exhaust gas analysis test. After identifying the fault codes, perform targeted repairs, such as replacing aging sensors or cleaning the throttle body. Don’t forget to regularly maintain the catalytic converter to extend its lifespan, reducing pollution and saving money.
I've been into car modifications for a while now, and the key to addressing excessive carbon monoxide lies in optimizing combustion efficiency. An imbalanced air-fuel mixture ratio is the main culprit—try adjusting the ECU programming or cleaning the MAF sensor. Excessive carbon buildup in the intake system affects airflow; soaking the pipe walls with carbon remover can alleviate this. Faulty oxygen sensors are also common; removing and cleaning them or replacing with new parts provides a quick fix. For aged catalytic converters, upgrading to high-efficiency eco-friendly models enhances conversion effectiveness. Regularly check oxygen levels during drives using a diagnostic tool to promptly address any issues. When carbon buildup is severe, adding a fuel system cleaner once helps avoid prolonged idling causing exhaust overlimits. Routine inspections ensure smooth system operation and compliant emissions.
