Why Do Cars Drip Water in Summer?

[DeBarrett]

It is quite normal for a car's exhaust pipe to drip water, which indicates that the engine is working properly, with complete combustion and good atomization effect. Reasons: The dripping water from the car's exhaust pipe is due to the fact that after the gasoline is completely burned, it produces 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 degrees, 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 gas. 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. Minimum conditions for exhaust pipe dripping: The mixture ratio of gasoline and air is correct. The engine's cylinder pressure is normal. The exhaust pipe temperature is low.
