Is it normal for water to come out of the engine exhaust pipe?

[Tyler]

When the ambient temperature is relatively low, the car's exhaust pipe may drip water, which is a very normal phenomenon. The reasons for water in the engine exhaust pipe are as follows: 1. Reason one: Because gasoline completely burns to produce water and carbon dioxide, water at high temperatures is in the form of water vapor, which is colorless and transparent. However, when the temperature drops below 100°C, the water vapor condenses into water. If the condensed water droplets are very small and suspended in the air, the water vapor appears as white smoke. When the ambient temperature is low, the white smoke from the exhaust pipe is water vapor; if the condensed water droplets accumulate, they turn into water. 2. Reason two: The water droplets discharged from the exhaust pipe are the result of water vapor generated after gasoline combustion condensing in the exhaust pipe and muffler. However, when the ambient temperature is high, the water vapor is discharged before it condenses. When the ambient temperature is low, the water vapor condenses into water droplets on the exhaust pipe wall and is discharged with the exhaust flow.
