The reason for water dripping from the exhaust pipe box: After 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. 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 smoke. When the ambient temperature is low, white smoke from the exhaust pipe is water vapor; if the condensed water droplets accumulate, they turn into water. Conditions required for dripping: The air-fuel ratio is 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 is normal, meaning there is no wear inside the engine block, and components such as cylinder liners and sealing rings are in good condition.
