What is the difference between dripping and spraying water from the exhaust pipe?

[StBennett]

There is no difference between dripping and spraying water; if the throttle is large, it may spray water. When the ambient temperature is low, water vapor will condense into water droplets on the exhaust pipe wall and flow out along the pipe. This is a normal phenomenon. Below are relevant details: 1. When the ambient temperature is relatively low, especially in winter, the car's exhaust pipe may drip water outward. This is actually a very normal phenomenon. This occurs because gasoline, when completely burned, produces water and carbon dioxide. At high temperatures, water exists as vapor, which is colorless and transparent. However, when the temperature drops below 100°C, 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 smoke. 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. 2. The water droplets discharged from the exhaust pipe are the result of water vapor generated from gasoline combustion condensing in the exhaust pipe and muffler. However, when the ambient temperature is high, the water vapor is discharged before it can condense. When the ambient temperature is low, the water vapor condenses into water droplets on the exhaust pipe wall and is discharged with the exhaust flow.
