What Causes Water to Come Out of a Car's Exhaust Pipe?

[MacMatthew]

The reasons for water coming out of a car's exhaust pipe are: 1. After gasoline is completely burned, it forms water and carbon dioxide. Water produces steam at high temperatures, which is colorless and transparent. When the temperature drops below 100 degrees, the steam turns back into water; 2. When the ambient temperature is low, the white smoke emitted from the exhaust pipe is steam, which condenses and accumulates into water droplets. Methods for maintaining the exhaust pipe include: 1. Preventing muffler corrosion: Avoid water entering the muffler during car washing or driving in the rain. If water accidentally enters, start the engine and let it idle for 10 minutes to expel the accumulated water; 2. Preventing muffler discoloration: Clean the muffler surface promptly if it is covered with a large amount of mud or dirt to prevent affecting its heat dissipation.
