Why is there water coming out of the car's exhaust pipe?

[EliasDella]

The reason for water coming out of the car's exhaust pipe is: The engine exhaust contains water vapor, which condenses into small water droplets when it encounters cold temperatures. These droplets accumulate in the exhaust pipe and are expelled under the force of exhaust pressure during acceleration. In winter, the lower temperatures make condensation more likely. Generally, the condition of the engine can be reflected by the state of the exhaust from the exhaust pipe. The exhaust pipe includes the front exhaust pipe and the rear exhaust pipe. The water droplets expelled from the exhaust pipe are the result of water vapor generated after gasoline combustion condensing in the exhaust pipe and muffler. When the ambient temperature is high, the water vapor is expelled before it can condense. When the ambient temperature is low, the water vapor condenses into water droplets on the walls of the exhaust pipe and is carried out with the exhaust flow.
