What Are the Harms Caused by Automobile Exhaust?

[EliasDella]

Lead-containing gasoline causes automobile exhaust to contain high concentrations of lead, which poses serious harm to human health. The following are relevant solutions for non-compliant automobile exhaust: 1. Replace the spark plugs: Both new and old ones can be used, as long as the electrode points are cleaned with sandpaper and the gap is properly adjusted. 2. Clean the distributor contacts and rotor contacts: Adjust the ignition timing. Delaying the ignition timing will significantly reduce the NO (nitric oxide) content in the exhaust, which is crucial—please remember this! Due to the delayed ignition timing, the combustion time in the combustion chamber will be shortened, and the maximum combustion temperature will decrease, thereby reducing the emission of hydrocarbons and nitrogen oxides. However, this will result in a decrease in engine power.
