Why Does Water Come Out of a Car's Exhaust Pipe?

[VonTalia]

Water coming out of a car's exhaust pipe is caused by the complete combustion of gasoline, which produces only carbon dioxide and water. When gasoline combusts in the engine cylinders, the temperature ranges from 400 to 800 degrees Celsius. Under high temperatures, water is vaporized. In cold weather, the vaporized water is condensed by the exhaust pipe into water mist, which then accumulates into droplets and flows out. The car's exhaust pipe is installed between the engine exhaust manifold and the muffler, providing a flexible connection for the entire exhaust system. This helps reduce vibration and noise, facilitates installation, and extends the lifespan of the exhaust and muffler system. Its structure consists of a double-layered corrugated pipe covered with a steel wire mesh sleeve, with clamping rings at both ends. To enhance noise reduction, the corrugated pipe may include an expansion joint or an additional mesh sleeve inside.
