What Causes a Cruze to Suddenly Emit a Large Amount of White Smoke?

[Raphael]

If a Cruze suddenly emits a large amount of white smoke, it could be water vapor expelled while driving in low-temperature environments, which is a normal phenomenon. However, it could also be caused by excessively advanced ignition timing or an overly lean air-fuel mixture, resulting in white smoke. To determine the fault point, it is necessary to check the ignition timing advance angle and the air-fuel mixture concentration. Here is some additional knowledge: 1. Black smoke from a car: This is often due to the use of poor-quality fuel, such as accidentally filling up with low-quality gasoline containing many impurities, which reduces combustion efficiency and leads to black smoke. Alternatively, a clogged air filter can cause an overly rich air-fuel mixture, leading to insufficient oxygen supply to the engine and incomplete combustion. 2. Blue smoke from a car: This occurs when engine oil enters the combustion chamber, commonly referred to as 'burning oil.'
