What to Do When Exhaust Carbon Monoxide Levels Exceed Standards?

[StHazel]

Solutions for excessive carbon monoxide in exhaust include: inspecting the air filter, spark plugs, intake air temperature sensor, and intake manifold pressure sensor; adding dual-core friction-reducing repair agents and high-efficiency cleaners; if ineffective, cleaning the three-way catalytic converter. Excessive exhaust emissions mainly refer to carbon monoxide, nitrogen oxides, nitrogen-hydrogen compounds, etc., exceeding national exhaust emission standards. These excessive emissions are directly related to carbon deposits in the fuel supply system. More carbon deposits lead to severe exhaust emissions, while fewer result in minor issues. Excessive carbon monoxide in car exhaust is primarily due to poor combustion. Causes of this phenomenon include: failed spark plugs, poor ignition, excessive cylinder wall clearance, uncalibrated valve timing, failed three-way catalytic converter, poor fuel injector atomization, etc.
