Why is water dripping from the exhaust pipe?
1 Answers
The reason for water dripping from the exhaust pipe is: After gasoline is completely burned, it produces water and carbon dioxide. Water exists as steam at high temperatures, which is colorless and transparent. When the temperature drops below 100 degrees, the steam condenses into water. If the condensed water droplets are very small and suspended in the air, the steam appears as white smoke. When the ambient temperature is low, the white smoke from the exhaust pipe is actually steam; if the condensed water droplets accumulate, they turn into water. Water dripping requires three conditions: the air-fuel ratio must be correct, whether the engine is fuel-injected or carbureted, indicating that the vehicle's fuel supply system is functioning properly without issues, the compression ratio is normal, and fuel consumption is within the normal range; the engine cylinder pressure must be normal, indicating that there is no internal wear in the engine block, and components such as the cylinder liner and sealing rings are in good condition.
