How to Deal with Car Exhaust?
2 Answers
Methods for treating car exhaust: 1. Use a water tank to wash and filter harmful molecules in car exhaust, converting them into harmless substances; 2. Water washing: The water washing method involves using catalysts to convert CO into CO2, and HC into CO2 and H2O, etc. Commonly used catalysts include metal oxides such as manganese oxide, copper oxide, chromium oxide, nickel oxide, and precious metals like platinum. A large amount of car exhaust is not harmless. During the combustion of gasoline, pollutants such as nitrogen oxides are released, which directly contribute to global warming. Hydrocarbons can form highly toxic photochemical smog, which is harmful to human health and can produce carcinogenic substances. The white smoke generated can damage livestock, fruits, rubber products, and buildings.
I've been driving for over a decade, and managing vehicle emissions mainly relies on routine maintenance and driving habits. Regularly changing the engine oil and air filter ensures more complete combustion in the engine, reducing black smoke emissions. When the exhaust system components, like the catalytic converter, age or get clogged, they may produce unusual odors or exceed emission standards, requiring timely repairs. I prefer smooth driving, avoiding sudden acceleration and hard braking, which reduces exhaust emissions and saves fuel. Getting an emissions test every six months at a reliable repair shop is sufficient. These small steps are simple yet practical—over time, emission issues naturally resolve, and the car's lifespan extends. Years of driving have taught me that being eco-friendly isn't just about saving money; it also greatly benefits air quality and community health.
