Why is water dripping from the car engine exhaust pipe?

[GabriellaDella]

It is normal for water to leak from the engine exhaust pipe. After gasoline is fully burned in the engine combustion chamber, carbon dioxide and water vapor are produced. This water vapor is discharged to the end of the exhaust pipe along with the exhaust gas. Since the external temperature is lower than that inside the exhaust pipe, the water vapor condenses into small water droplets, resulting in the dripping phenomenon. Introduction to the engine: 1. An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, steam engines, jet engines, electric motors, etc. 2. The engine can refer to both the power generation device and the entire machine including the power device, such as gasoline engines and aircraft engines. Its types include internal combustion engines, external combustion engines, electric motors, etc.
