What are the solutions for automobile exhaust?

[DiAlaina]

Methods for treating automobile exhaust include cleaning the three-way catalytic converter, cleaning the air filter, and performing a deep engine cleaning. The most fundamental approach is to change the vehicle's power source, such as developing electric vehicles and alternative fuel vehicles, which produce little or no polluting gases. Cleaning the three-way catalytic converter: When the engine's air-fuel mixture does not burn completely, a large amount of carbon deposits is produced. These deposits are discharged through the exhaust pipe and adhere to the interior of the three-way catalytic converter. Over time, this can easily lead to clogging, resulting in excessive automobile exhaust emissions. Soaking and cleaning the three-way catalytic converter with an oxalic acid solution, followed by rinsing several times with clean water, can resolve the issue. Cleaning the air filter: The main function of the air filter is to remove particulate impurities from the air. If it is not cleaned or replaced for a long time, the air filter may accumulate many impurities, reducing its effectiveness in filtering suspended particles. This can lead to accelerated engine wear and carbon buildup, resulting in excessive exhaust emissions. Therefore, when the air filter is contaminated to a certain extent, it must be cleaned. Deep engine cleaning: If automobile exhaust emissions still fail to meet standards after cleaning the three-way catalytic converter and air filter, a deep engine cleaning may be necessary. This not only effectively reduces exhaust emissions but also helps maintain the vehicle, significantly improving its operating condition. Management measures: Control at the source by strengthening the new vehicle admission system. New vehicles that do not meet emission standards should be prohibited from leaving the factory or being sold, encouraging automakers to accelerate the development of energy-saving and emission-reducing vehicles. Establish interdepartmental coordination mechanisms. Automobile exhaust management requires multi-departmental collaboration for comprehensive oversight. Regions should establish and improve joint meeting systems for automobile exhaust management, forming a supervision system that includes new vehicle control, fuel quality supervision, regular testing of in-use vehicles, label issuance, network transmission, law enforcement inspections, repair management, and scrapping. Conduct motor vehicle exhaust emission testing. Vehicles that fail to meet standards should be ordered to rectify within a specified period. Those that remain non-compliant after the deadline should be blacklisted, with license plate numbers published by departments such as traffic police, transportation, and environmental protection for elimination. Strengthen automobile exhaust treatment. On the basis of establishing exhaust testing lines, exhaust treatment institutions should be set up to install catalytic purifiers, modify engines, or use cleaning additives for non-compliant vehicles, ensuring exhaust emissions meet standards. The main pollutants in automobile exhaust are carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx), and lead (Pb).
