Why is water leaking from the car's exhaust pipe?

[MacKarter]

Water leaking from the car's exhaust pipe is water vapor produced after gasoline combustion. Here are some explanations about water leaking from the car's exhaust pipe: 1. Water leaking from the car's exhaust pipe is a normal phenomenon as long as it's not severe. In fact, it indicates good combustion efficiency of the car. However, if the leakage is severe, it means there's a problem with the car, and you should promptly visit a 4S shop for inspection and repair by maintenance personnel. 2. The specific principle of exhaust pipe water leakage: After gasoline combustion, water and carbon dioxide are formed. When the ambient temperature is low, the water vapor condenses into water droplets on the exhaust pipe wall and leaks out from the exhaust pipe.
