What is the fault when white exhaust is emitted from the engine exhaust pipe?

[ArthurFitz]

There are two situations when white exhaust is emitted from the engine exhaust pipe: 1. White smoke: When white smoke is emitted from the exhaust pipe, it may be due to dirt on the vehicle's air filter causing insufficient air intake, or a fault in the carburetor, or contamination of the oxygen sensor in the exhaust pipe, which prevents the computer from providing correct information for air distribution. 2. White vapor smoke: Normal white vapor smoke is caused by the exhaust gas from the exhaust pipe. When the temperature of these exhaust gases reaches a certain level, they condense into water droplets; if a large amount of white vapor smoke is emitted from the exhaust pipe while the engine is running, check for water in the fuel tank, whether the cylinder gasket is damaged, whether there are cracks in the cylinder, and whether the cylinder sleeve sealing ring is in good condition.
