What are the causes of engine smoke?

[VanChloe]

The causes of engine smoke: 1. Blue smoke from the engine is related to burning engine oil, indicating that the oil entering the cylinder combustion chamber cannot be fully burned, resulting in blue smoke being emitted from the exhaust pipe; 2. It is normal for the engine to emit white smoke when starting a cold car in winter, as this is just the color of water vapor condensing in the cold. The car engine is the device that provides power for the car, serving as the heart of the car, determining its power, fuel economy, stability, and environmental friendliness. Depending on the power source, car engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrids, among others.
