What to Do When Exhaust CO Levels Exceed Standards?
2 Answers
Solutions for excessive CO levels in vehicle exhaust are as follows: 1. Clean the three-way catalytic converter. Use an IV bottle to hang the cleaning solution onto the car's vacuum tube. The solution burns off carbon deposits in the combustion chamber, removing them and increasing engine power. Then, clean the contaminated three-way catalytic converter in the exhaust pipe to restore its original function of energy conservation and emission reduction. 2. Replace a failed or aged three-way catalytic converter. If the precious metals platinum, rhodium, and palladium inside have deteriorated and cleaning does not restore their exhaust purification effect, spray a nano-precious metal liquid containing platinum, rhodium, and palladium into the removed three-way catalytic converter. 3. If the three-way catalytic converter is hollow, purchase a Fire Lotus three-way catalytic metal soft carrier available on the market and insert it into the exhaust pipe to serve as the original carrier in the three-way catalytic converter. For models equipped with a three-way catalytic converter, this can also enhance exhaust purification effects.
As a veteran driver with nearly twenty years of experience, I've found that when CO emissions exceed the standard, the first thing is not to panic. The most common cause is incomplete combustion in the engine, possibly due to excessive fuel injection or insufficient air intake. I would check if the spark plugs are aged or burnt—poor ignition can lead to wasted fuel and higher CO emissions. Additionally, inspect the air filter to see if it's clogged with dust, as this can reduce airflow and worsen combustion. If CO levels remain high after simple cleaning, it might be time to consider issues with the oxygen sensor or catalytic converter, as these are critical components for controlling exhaust purification. Exceeding the standard not only means failing the annual inspection but could also result in fines, and worse, it increases environmental pollution. So, whenever I notice this issue, I act immediately: start by checking basic components, and if that doesn't help, head to the repair shop for professional diagnosis. Regular oil and air filter changes during maintenance can make the engine run more efficiently and reduce the risk of CO exceeding the standard. Remember, safety comes first—don't delay repairs.
