What Causes Water Dripping from the Car Exhaust Pipe?

[LorenzoRose]

Water dripping from the car exhaust pipe is a normal phenomenon, commonly observed in new cars. This occurs in all types of vehicles and indicates that the fuel inside the engine is burning efficiently. During operation, the engine burns gasoline, producing water vapor and carbon dioxide. When the external temperature is low, the water vapor condenses into droplets as it passes through the exhaust pipe. If the car's exhaust appears as a milky white oil mist that solidifies upon hitting the ground, it is likely due to poor fuel vaporization. This condition usually disappears after the engine has been running for some time.
