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

[GenevieveLynn]

The reason for water coming out of the car's exhaust pipe is: During driving, gasoline undergoes complete combustion inside the engine, producing water and carbon dioxide after complete combustion. At high temperatures, water is colorless and transparent water vapor. When the temperature drops below 100 degrees Celsius, the water vapor condenses into water and drips from the exhaust pipe. The conditions for water to come out of the car's exhaust pipe are: 1. The air-fuel mixture ratio must meet the normal value; 2. The engine cylinder pressure is normal, with no significant wear inside the engine block or negligible wear, and the cylinder liners and sealing ring components are intact; 3. The exhaust temperature is normal, with most of the heat generated by the engine remaining in the cylinders.
