What is the principle of atomization (white water vapor in exhaust pipe) when a car burns? Why is there fog on the new motorcycle, and it will disappear after about half a year?

The more completely the gasoline burns, the more water is discharged, which also shows that the fuel system is very good and clean, and can achieve the most fuel-efficient state.

Then why are cars that have been foggy for more than half a year or longer not good? That's because with the passage of time, the whole fuel system will enter a lot of dust, impurities in gasoline and so on. Moreover, the nozzle and throttle of the fuel system will be blocked, the atomization is not good, and there will be insufficient combustion. This is also why driving for a long time will consume oil.

Finally, if the fuel system is not cleaned regularly, it will achieve the most fuel-efficient and best power effect.
