What Causes White Smoke from Car Exhaust?

[LeJackson]

Here are the reasons why a car emits white smoke: 1. Problem with the air filter - When the car's air filter is dirty and there is insufficient air intake, white smoke may appear from the exhaust pipe; 2. Malfunction of the carburetor; 3. Issue with the oxygen sensor in the exhaust pipe, causing the sensor to fail to provide correct information; 4. Too much water in the gasoline; 5. If the engine runs unevenly, it may be due to wear on the engine cylinder head gasket, creating a gap that allows a large amount of water from the cooling system to enter the combustion chamber; 6. If the smoke increases with acceleration and is accompanied by a pungent odor, this indicates an engine malfunction, and the piston rings need to be replaced.
