What methods do cars use to solve exhaust emission problems?

[LeDeclan]

Cars solve exhaust emission problems through the following methods: 1. Replace spark plugs and clean the throttle with cleaning agent; 2. Adjust the ignition timing, delay the ignition time, which will significantly reduce the nitrogen oxide content in the exhaust; 3. Before filling out forms and paying fees at the inspection station while waiting for inspection, ensure the car is in an idling and warmed-up state; 4. Use an automobile exhaust purifier; 5. Clean the three-way catalytic converter and oxygen sensor, and clean the air filter. The impacts of automobile exhaust emissions are: 1. Lead in the exhaust enters internal organs, disrupting the acid-base balance and causing lead poisoning; 2. Carbon monoxide in the exhaust hinders blood absorption and oxygen delivery in the human body, harming health and producing carcinogenic substances; 3. Inhalable particulate matter irritates the eyes and lungs, increasing the risk of respiratory diseases.
