What does white smoke from the exhaust pipe mean?

[MacOscar]

White smoke from the exhaust pipe is caused by cold weather or water entering the combustion process. Here are specific explanations for white smoke from the exhaust pipe: 1. Cold weather: Burning gasoline produces water vapor, which turns into white smoke when it meets cold air. 2. Water entering combustion: If the cylinder gasket is worn, creating gaps, coolant from the cooling system can enter the combustion chamber in large quantities. Water that participates in combustion forms water vapor, which is then expelled through the exhaust pipe. Another possible reason is the use of low-quality gasoline. Some inferior gasoline may be adulterated with water by unscrupulous sellers.
