Why is there water dripping from the car chassis?

[Gianna]

Reasons for water dripping from the car chassis: During summer, the high temperature inside the car usually requires the cooling system to be activated to lower the interior temperature. At this time, the moisture in the hot air inside the car will condense on the surface of the very cold evaporator heat-absorbing fins, and the water droplets are collected by the plastic casing of the evaporator and drained out of the car through pipes. This is a normal phenomenon. Water dripping from the muffler and exhaust pipe at the rear of the car is also normal. When gasoline is injected into the cylinder and mixed with air, it burns completely in the combustion chamber, mainly producing carbon dioxide and water. The water is discharged into the atmosphere in the form of gaseous water vapor at high temperatures. Since the muffler is located at the rear of the car where the temperature is relatively low, the water vapor will condense into liquid water when it encounters the cold. Some of this liquid water, driven by the high-speed operation of the engine and the airflow, is discharged from the exhaust pipe, resulting in the phenomenon of water dripping or even spraying from the exhaust pipe.
